Andalucia Lake Worth Roof Leak Repair, Case Study


A ceiling stain does not always point to the roof detail that looks most suspicious from the outside. On this project in Andalucia, a gated community in western Lake Worth near Wellington, a homeowner who was preparing to sell the home was considering a repair proposal of nearly $2,000 for the wrong area. The original estimate focused on a dryer vent. A real estate agent partner referred the homeowner to BLU Roofing for a second opinion, and a methodical inspection showed that the actual leak source was about five feet away at a different roof penetration.

Quick Summary

BLU Roofing completed an Andalucia Lake Worth roof leak repair on a two-story tile roof after a real estate agent referred the homeowner for a second opinion. Attic evidence did not support the original dryer-vent diagnosis. We inspected the ceiling-stain location, attic, roof penetrations, and vent pipe, then used controlled hose testing to isolate a small gap in the lip of a lead pipe boot. After drying and sealing the precise opening, the leak repair was completed the same day for a $500 service call and repair. More than six weeks later, after substantial South Florida rain, the repair was still holding.

Watch the controlled roof leak diagnosis that identified the exact source before any repair was made.

Why a Second Opinion Made Sense

This home, located in the Andalucia community in western Lake Worth, was under contract preparation for sale. The homeowner had noticed water staining on the ceiling and needed a reliable answer before moving forward. A previous roofing company had identified the dryer vent as the suspected leak source and proposed a repair of nearly $2,000. The homeowner had questions about that diagnosis, and a real estate agent who works with BLU Roofing referred us for a second opinion.

We are not in a position to say what testing another company did or did not perform. What we can say is that the visible ceiling stain, the attic evidence, and the dryer-vent location did not line up during our inspection. A correct repair starts with a correct diagnosis. When the source is uncertain, replacing the first component that appears suspicious can be expensive and still leave the homeowner with the same leak.

For a homeowner preparing to sell, that distinction matters even more. The goal is not simply to produce an invoice showing that a repair was performed. The goal is to identify the actual source of the water intrusion, correct it, and have confidence that the repair will hold during the next rainfall.

The Attic Evidence Did Not Match the Dryer Vent

We started where a proper leak inspection should start: inside the home and inside the attic. The stain location is a clue, but it is not a map. Water can travel along the underside of roof decking, along framing members, down plumbing pipes, or along other building components before it becomes visible on a ceiling.

At the dryer-vent area, we did not find evidence of active or prior water intrusion that correlated with the ceiling staining. About five feet away, however, we found moisture around a separate vent pipe penetration. That gave us the right general area, but it did not prove the cause.

Andalucia Lake Worth roof leak repair attic inspection

Attic inspection during the Andalucia Lake Worth roof leak repair. Finding moisture near a pipe established the general location, but controlled testing was still needed to prove exactly where the water entered.

There were several possible explanations. Water could have been entering around the roof penetration. The vent pipe itself could have been leaking. A 90-degree elbow fitting inside the attic could have been compromised. Or there could have been another small defect nearby. Each possibility needed to be tested, rather than repaired on assumption.

Controlled Testing, One Possibility at a Time

Once we narrowed the general area, we used a controlled hose test to eliminate each possible source individually. This is a straightforward method, but it needs to be performed patiently. Applying water broadly over a large area can make it difficult to know which detail is actually leaking. The point is to isolate one component at a time while someone checks the attic for water.

First, we hose-tested the roof penetration and the surrounding roof area. We checked from inside the attic, and nothing showed up. Next, we ran water through the vent pipe itself to rule out a leak in the pipe or its 90-degree elbow fitting. We went back into the attic, and again found no water. At that stage, we had enough evidence to rule out the primary penetration and the vent pipe as the source.

Andalucia Lake Worth roof leak repair controlled hose test

A controlled hose test on the concrete tile roof in Andalucia. Testing each detail separately helped BLU Roofing rule out the suspected dryer vent and identify the actual water entry point.

These steps were not wasted time. They were the work. A small amount of sealant may ultimately be all a repair needs, but the skill and value lie in proving what needs to be sealed, and just as importantly, what does not.

The Actual Source: A Small Gap at the Lead Pipe Boot

With the main penetration and the vent pipe ruled out, we returned to the roof and examined the lead pipe boot more closely. Lead boots are designed to conform around a pipe penetration, but a tiny gap at the lip can become a path for water under the right conditions, especially during wind-driven South Florida rain.

We noticed a very small opening at the lip of the lead pipe boot. Rather than treating it as a theory, we concentrated water directly on that exact point for an extended period. Back in the attic, we finally reproduced the leak. A small amount of water began dripping down the outside of the pipe. We had found the actual source of the ceiling stain.

That result explains why the dryer-vent repair would not have been the right first move. The dryer vent was not the problem based on the interior evidence and the controlled tests. The leak was coming from a distinct penetration roughly five feet away.

Why Roof Leak Diagnosis Matters More Than Guessing

Roof leaks are rarely as simple as they appear from the ceiling below. The location of a water stain can be displaced from the actual entry point, especially on a two-story tile roof with framing, penetrations, and attic space that allow water to travel. That is why a visual roof check alone can be misleading.

For difficult leaks, BLU Roofing combines the following information before recommending a repair:

  • The precise location of the interior ceiling stain.
  • Attic conditions, including moisture, water marks, and the direction water is traveling.
  • Exterior roof conditions around every relevant penetration and flashing detail.
  • Controlled hose testing, when the source cannot be proven through inspection alone.

The objective is not to identify something that might be leaking. The objective is to reproduce the leak and prove exactly where the water is getting in before repairing it. That approach prevents unnecessary work, protects the homeowner’s budget, and gives the repair a much higher chance of lasting.

It is also why a second opinion can make sense when a diagnosis or estimate does not add up. The lowest quote is not automatically the right answer, and neither is the highest. The right answer starts with knowing what actually needs to be fixed.

The Repair and the Result

Once we isolated the exact source, the repair itself was simple. We allowed the lead pipe boot to dry, then properly sealed the small opening at the lip. There was no need to replace the entire pipe boot, repair the dryer-vent area, or start replacing unrelated roof details because those components had been tested and ruled out.

The inspection and repair were completed the same day. The service call and repair total was $500. The value was not the small amount of sealant used at the end. The value was the diagnostic work involved: multiple trips onto a two-story tile roof, attic access, a 40-foot ladder, controlled water testing, and the experience to eliminate each possible source without jumping to the most expensive repair.

More than a month and a half after the repair, the homeowner had experienced plenty of South Florida rain without any further leaking. That follow-up period provided an additional layer of confirmation that the correct source had been identified and repaired.

Steeplechase Palm Beach Gardens Roof Inspection: Repair or Replace?

Multiple previous repairs. An active leak. Slipping tiles. Rotted fascia. If you described those findings to most homeowners, they would assume the answer is a full roof replacement. On a recent inspection in the Steeplechase community of Palm Beach Gardens, that was not my recommendation. This post walks through exactly what we found, why I voted repair over replace, and what that decision process should look like for any homeowner facing a similar situation.

Quick Summary

BLU Roofing was referred by a real estate agent to inspect a home in Steeplechase, Palm Beach Gardens. The original call was to assess and bid the flat roof, which does need replacement. While on the property, we walked the entire main concrete tile roof and found three previous repairs, one active leak, slipping tiles, and fascia that needs attention. Despite that repair history, the recommendation for the 18-year-old tile roof is repair, not replacement. All four leak areas are concentrated at high-flow water areas and penetrations, not spread across the field of the roof. That distinction matters.

How We Got There: The Flat Roof Call

This visit started with a referral from a real estate agent partner. The home is being prepared for sale in Steeplechase, and the agent identified that the flat roof section needed to be replaced before listing. That is a common scenario in Palm Beach Gardens, where many homes have a combination of a pitched concrete tile roof and a flat section over a garage, patio, or addition. We came out, assessed the flat roof, and submitted a bid for that replacement.

While we were already on the property, we did what any thorough roofing contractor should do: we walked the entire roof and the full property perimeter. If you are going to get on a roof, there is no reason to look at only one section. A complete walkthrough takes a relatively small amount of additional time and gives the homeowner a full picture of everything going on above their heads, not just the one issue that prompted the call.

At the end of the visit, we provided a full written inspection report documenting every finding on the property, with photos, condition notes, and our honest assessment of what needs immediate attention versus what can be monitored over time. The flat roof needs to be replaced. The main tile roof, despite its repair history, does not, and here is why.

What We Found on the Tile Roof

The main tile roof is approximately 18 years old and sits at a 7/12 pitch, which is a steeper-than-average pitch for South Florida. Here is what the inspection turned up:

  • Three previous repairs: Evidence of prior repair attempts at three separate locations on the roof.
  • One active leak: One location with an ongoing water intrusion issue.
  • Slipping tiles: Several tiles that have shifted out of position, which can create gaps and expose the underlayment to direct water flow.
  • Fascia damage: Sections of fascia board that need attention, likely from water exposure over time.
  • Mechanically fastened tile system: The tiles are attached with one screw per tile, with no foam adhesive. There is a single layer of self-adhered underlayment installed direct-to-deck beneath them.

On paper, that list sounds like a roof that is at the end of its useful life. In practice, the picture is more nuanced.

Why I Voted Repair, Not Replace

The recommendation here is to repair the tile roof, not replace it, and the reasoning comes down to two things: age and leak pattern.

At 18 years old, a concrete tile roof in South Florida is not old. Concrete tile is one of the most durable roofing materials available, with a properly installed system capable of lasting 40 to 50 years or more. The tile itself on this roof is not failing. The field of the roof is intact. There is no widespread granule loss, no systemic cracking, and no evidence that the tile as a material has reached the end of its serviceable life. Recommending a full replacement on an 18-year-old tile roof with no systemic failure would not be an honest assessment.

The second factor is the repair history. Four leak areas over 18 years sounds like a lot until you look at where those leaks occurred.

What the Leak Pattern Actually Tells You

Every single one of the four leak areas on this roof occurred at a high-flow water area or a roof penetration: three returns and one penetration. Not one of the leaks originated in the open field of the roof. That is a critical distinction.

A roof that is leaking in random locations across the field, with no clear pattern, is a roof where the underlayment system is failing broadly. That is a replacement conversation. A roof where every single leak has occurred at a return, a valley, a penetration, or a transition point is a roof where the installation details at those specific locations were not built to a high enough standard. That is a repair and reinforcement conversation.

High-flow water areas are exactly what the name implies: locations on the roof where water concentrates, accelerates, and exerts significantly more pressure on the roofing system than the open field does. Returns, valleys, roof-to-wall transitions, and penetrations all fall into this category. When these areas are built to the minimum code requirement and nothing more, they are the first places a roof will develop problems over time. That appears to be what happened here.

How BLU Roofing Installs Differently

This inspection is a useful illustration of why we build our roofing systems the way we do. Building code establishes the minimum requirement. We do not want the most vulnerable areas of a roof built to the minimum.

On every BLU Roofing reroof, the high-flow water areas receive additional layers of protection beyond what code requires. Valleys get ice and water shield as a first layer, then valley metal, then CertainTeed SA granulated cap sheet on top. Returns and roof-to-wall flashings get ice and water shield underneath them before the flashing is installed. Penetrations get additional peel-and-stick membrane applied around the full perimeter of the base flashing. The perimeter eave gets ice and water shield before the drip edge and before the field underlayment.

The field of the roof gets Polyglass TU Plus single-ply self-adhered underlayment installed direct-to-deck, and the tiles are set with ICP Polyset AH-160 two-part polyurethane foam adhesive rather than mechanical fasteners. Foam adhesive means no screws or nails penetrating the underlayment across the field of the roof. The only mechanical fasteners in the field are at the perimeter row, where code requires a higher wind uplift resistance.

The roof we inspected in Steeplechase was built with one screw per tile and a single layer of self-adhered underlayment, with no additional reinforcement at the high-flow areas. That system meets the minimum code requirement. It is also the reason this roof has had four leaks in 18 years, all at the exact locations where the system was most vulnerable.

The Takeaway for Homeowners

If you are a homeowner in Steeplechase or anywhere in Palm Beach Gardens dealing with a tile roof that has had multiple repairs, the most important question is not how many repairs there have been. It is where the repairs have been and why.

Multiple repairs concentrated at high-flow water areas and penetrations tell a different story than repairs scattered across the field of the roof. The first scenario points to installation details that were not built to last. The second points to a system that is failing broadly. Before agreeing to a full roof replacement, make sure you understand which situation you are actually in.

A proper inspection documents every finding with photos, identifies the pattern of failures, assesses the age and overall condition of the roofing system, and gives you an honest recommendation based on all of that information, not just a quote for the most expensive option. That is what we did here, and it is what we do on every roof we inspect.

If you are in Steeplechase, Palm Beach Gardens, or anywhere in Palm Beach County and want an honest assessment of your tile roof’s condition, contact Peter Menke at 561-379-5364. We will tell you what we find and what we actually recommend, even if that recommendation is not a full replacement.

Project Spotlight: Lake Charleston Concrete Tile Reroof in Lake Worth


Every reroof project tells a story. This one, completed in the Lake Charleston community of Lake Worth, is a good example of what a well-managed concrete tile reroof looks like from the first phone call to the final inspection. It also happens to be a project where the homeowner used the My Safe Florida Home program to offset $10,000 of the cost, so we will walk through that process as well. If you are a homeowner in Lake Charleston or a similar HOA community in Palm Beach County considering a reroof, this post is written for you.

Quick Summary

BLU Roofing completed a full concrete tile reroof in Lake Charleston, Lake Worth. The project involved HOA approval through the Lake Charleston Homeowners Association, a Palm Beach County permit, Eagle Malibu concrete tile in Palm Beach Blend, a single-ply direct-to-deck Polyglass TU Plus underlayment system with reinforced high-flow water areas, ICP Polyset AH-160 foam tile adhesive, and a Solatube RM2400 solar attic fan. The homeowner received the full $10,000 My Safe Florida Home matching grant. The tear-off and dry-in were completed in one day, and the finished tile was installed one week later.

The Estimate Process

This project started with a phone call from a homeowner in Lake Charleston who had been following BLU Roofing on social media and had watched enough of our content to feel confident in reaching out. When a homeowner comes to us already educated about the process, it makes for a much smoother experience for everyone.

Before putting together an estimate, we do a full roof inspection. This is not just a quick look from the driveway. We get on the roof and assess the condition of the existing tile, the underlayment, the flashings, the fascia, the decking, and every penetration on the roof. We also ask the homeowner the right questions: Where are you in the decision-making process? What is your timeline? What is most important to you in choosing a contractor? What concerns do you have about the process? Understanding what matters to the homeowner is just as important as understanding the condition of the roof.

Once the estimate was ready, we sat down together with the homeowner and his wife and walked through the entire scope of work, the materials, the process, and the timeline. We do not email estimates and wait for a call back. We review them in person so every question gets answered before a decision is made.

HOA Approval and Permitting

Lake Charleston is governed by the Lake Charleston Homeowners Association, which requires that any reroof use concrete tile matching the community’s approved materials list. This is common in Palm Beach County HOA communities, and it is something we handle routinely. The HOA had a pre-approved list of tile profiles and colors to choose from, and we worked with the homeowners to select the right option.

They chose the Eagle Malibu profile in Palm Beach Blend, a warm, multi-toned blend that complements the stucco homes throughout Lake Charleston beautifully. We had already completed a roof in this exact color and were able to send them photos of the finished product so they could see exactly what their home would look like before committing. They loved it, and so do we.

We handled the full HOA application: certificates of insurance listing both the association and the homeowner as additional insured, our contractor license, the product specifications, and photos of a completed reference roof. The HOA approved the application promptly.

On the permit side, this project fell under Palm Beach County Unincorporated jurisdiction. We submitted a complete permit application, and the county approved it within a few days. A fast permit turnaround comes from submitting everything correctly the first time. Incomplete applications are the most common reason permits get delayed, and we have a thorough checklist to prevent that.

The My Safe Florida Home Program

This homeowner had already been approved through the My Safe Florida Home program and had a $10,000 grant available. The program provides eligible Palm Beach County homeowners with matching grants for hurricane mitigation improvements, including qualifying roof replacements. For a $20,000 reroof, the state’s 2-to-1 matching grant covers $10,000, meaning the homeowner pays their portion and receives a reimbursement check from the state after the work is complete and passes final inspection.

It is important to understand that the program does not pay the contractor directly. The homeowner pays the full invoice, and then BLU Roofing helps put together the complete reimbursement packet, including the paid invoice, permit documentation, final inspection records, and all required product approval paperwork. We have processed dozens of these packets and know exactly what the program requires to get the reimbursement approved without delays.

If you are a Lake Worth or Palm Beach County homeowner who has already received a My Safe Florida Home inspection report, or if you are curious whether you qualify, we can walk you through the process. For a more detailed overview of the program, see our comprehensive My Safe Florida Home Program Guide.

Tile Ordering and Timeline Management

One of the most misunderstood aspects of a tile reroof is the timeline, specifically the relationship between when you order the tile, when you tear off the old roof, and when the tile arrives. This is where poor planning by a contractor can cause significant delays for a homeowner.

Because the Lake Charleston HOA can take up to 30 days to approve an application, we ordered the tile immediately after the contract was signed, scheduling delivery approximately two to two and a half months out to account for both the HOA approval timeline and the manufacturer’s lead time. The HOA approved the application quickly, which was great, but the more important planning factor was the tile delivery.

We received notification that the tile was ready approximately three weeks ahead of the scheduled delivery date. This is why the following rule is critical: a roofing contractor should tear off a tile roof approximately two to four weeks before the expected tile delivery date. If the tile arrives early and the roof is not dried in and ready, you miss your delivery window and go back to the end of the queue, potentially adding weeks to the project. We were ready. The roof was torn off and dried in on Thursday and Friday, and when the early delivery notification came on Friday afternoon, we were already prepared to receive it.

We had a seven-day window to schedule the delivery date from the moment we received that notification. We coordinated the install crew to pop the lines on Monday, scheduled tile delivery for Wednesday, and had the install crew back on Thursday. The tile was fully installed by Friday morning, exactly one week after the tear-off. That is what efficient project management looks like on a tile reroof.

Tear-Off, Inspection, and Dry-In

On tear-off day, we protect the property first: driveway, landscaping, and anything adjacent to the work area. This project had a zero lot line, meaning the neighboring homes are directly adjacent with no side yard buffer. We introduced ourselves to the neighbor before work began, explained what we were doing and how long it would take, and committed to keeping his side of the property as protected as possible throughout the process. He had been through a reroof himself and appreciated the communication. At the end of the job, he confirmed his property was left in perfect condition.

Aerial view of the tear-off in progress. The old concrete tile and underlayment have been removed, exposing the plywood roof deck. The zero lot line neighbors’ properties are visible on both sides.

The tear-off process involves removing all tile, all underlayment, and the entire roofing system down to the bare plywood decking. Any rotted, deteriorated, or damaged plywood is identified, photographed, and replaced. The same applies to fascia boards. We document everything with photos throughout the entire process using CompanyCam, so there is a complete photographic record of every condition we found and every repair we made.

Once all bad wood is replaced, the first city inspection takes place. This is the sheathing and re-nail inspection, which verifies that the roof deck is nailed to current building code standards and that there is no rotted or deteriorated decking remaining. In Palm Beach County Unincorporated, all inspections are conducted virtually: Peter gets on the roof and walks the inspector through everything live on video. This is a thorough process that gives the inspector a complete view of the work rather than a quick in-person glance.

The Roofing System: Products and Process

Once the sheathing inspection is passed, we begin installing the new roofing system. There is more than one way to build a proper tile roof system, and the right choice depends on the pitch, the climate, and the homeowner’s priorities. On this project, we used a single-ply direct-to-deck Polyglass TU Plus system, which is one of the highest-performing underlayment options available for Florida tile roofs.

We do not treat the entire roof as a uniform surface. The high-flow water areas, the locations where water concentrates and moves fastest, receive additional protection. Here is exactly how we built this system from the deck up:

Perimeter (eaves): Ice and water shield goes down as the first layer around the entire perimeter before the drip edge. The drip edge is then installed on top of this first layer but underneath the Polyglass TU Plus. This layering sequence ensures that water running off the eave edge cannot work back under the drip edge and into the roof system.

Valleys: Ice and water shield is installed as the first layer in every valley. On top of that, we install 26-gauge valley metal. On top of the valley metal, after the full Polyglass TU Plus field is installed, we add a layer of CertainTeed SA granulated cap sheet to fully bulletproof the valley. Valleys carry the highest volume of water on any roof, and they get the most layers of protection accordingly.

Wall flashings: Ice and water shield goes under all roof-to-wall flashings, including the section over the garage on this property.

Penetrations: Additional peel-and-stick membrane is applied around every pipe jack, gooseneck vent, and wall flashing before those components are installed.

Full field: Polyglass TU Plus self-adhered membrane is installed directly to the deck over the entire roof surface, back-nailed to code with all laps properly sealed. This system qualifies as the Secondary Water Resistance (SWR) layer, which is one of the key features that can unlock a homeowners insurance wind mitigation discount.

The second city inspection, the metal and tin tag inspection, takes place during this phase. The inspector verifies how the valleys are installed and how the drip edge is installed. Again, this is conducted virtually in Palm Beach County Unincorporated.

Tile Installation and Inspections

Before the first tile goes down, two things need to happen. First, the eave enclosure (also called bird stop) is installed around the entire perimeter. This is the component that closes off the open end of the first tile row at the eave, preventing birds, insects, and debris from getting underneath the tile. Second, the Trim Lock hip and ridge channel metal is installed on all hips and ridges. This channel is what the hip and ridge cap tiles will eventually lock into.

Then we pop the lines, which means laying out the tile courses across the entire roof to ensure perfectly straight, evenly spaced rows from eave to ridge. This is done before any tile is permanently set.

Tile installation on this 6/12 pitch roof uses ICP Polyset AH-160 two-part polyurethane roof tile adhesive for the full field. This is a foam adhesive applied in a measured patty pattern directly to the deck, and the tile is pressed into it. There are no nails, no screws, and no penetrations through the Polyglass TU Plus underlayment across the field of the roof. The perimeter row, the first course of tile around the entire eave, receives one screw per tile in addition to foam. This is required because the perimeter row must meet a higher wind uplift resistance standard: if wind is going to lift tiles, it starts at the edge, and that first row needs to hold tight.

Tile installation in progress. The Polyglass TU Plus is visible on the upper section of the roof, and the Eagle Malibu Palm Beach Blend tiles are being set from the eave up using ICP Polyset AH-160 foam adhesive.

The third city inspection is the in-progress inspection, conducted while tile installation is underway. The inspector checks three things: the eave enclosures, the hip and ridge channel metal, and the tile installation method, specifically the foam patty size and pattern. Once we receive the green light, installation continues to completion.

Why We Added a Solar Attic Fan

This homeowner also chose to add a Solatube RM2400 solar-powered attic fan during the reroof, and the timing was ideal. Here is something most homeowners do not know: when you go from a traditional felt underlayment system to a direct-to-deck peel-and-stick system like Polyglass TU Plus, you are significantly reducing the permeability of your roof deck.

With 30-pound felt, hot attic air could escape through small gaps in the plywood and through the felt itself. The permeability was not zero. With a fully adhered peel-and-stick system, the deck is essentially sealed. The permeability drops dramatically, closer to that of glass, which has zero permeability. That is excellent for waterproofing, but it means the attic has one less passive path for heat to escape. A sealed deck combined with a South Florida summer can push attic temperatures well above 140 degrees.

A solar-powered attic fan directly addresses this by actively exhausting hot air from the attic during the peak heat hours of the day. It reduces the heat load on the HVAC system, extends the life of the roofing materials from the inside, and helps manage attic humidity year-round. Installing it during a reroof is the ideal time because the roof is already open and the integration is clean. For a full overview of the Solatube RM2400 and how it works, see our Solatube RM2400 Installation Case Study.

Final Details, Cleanup, and Completion

Once the tile is fully installed, the hip and ridge caps are set and mortared. The mortar mix uses an oxide colorant matched to the tile color, so the mortar joints between the hip and ridge caps and the field tile blend seamlessly into the finished roof rather than standing out as a different color.

The fourth and final city inspection is the final inspection, where the inspector walks the entire completed roof virtually with Peter. They verify the mortar work, the overall installation quality, and that everything is complete per the approved permit documents. Once the final inspection passes, the permit is closed.

After the final inspection, we return to paint all pipe jacks and gooseneck vents to match the tile color as closely as possible. A silver steel pipe jack on a warm terracotta tile roof stands out immediately and makes the roof look unfinished. This is a detail that most contractors skip, and it is one of the finishing touches that separates a truly complete job from one that is just technically done.

Boynton Beach solar attic fan installation

Case Study: Solatube RM2400 Solar Attic Fan Installation in Boynton Beach

Most homeowners think about their roof as a barrier against rain. Fewer think about what is happening on the other side of that barrier, in the attic. On a recent job in Boynton Beach, we arrived to install a Solatube RM2400 solar-powered attic fan on an 18-year-old three-tab shingle roof. The attic temperature was 147 degrees. Before we were done, we had also discovered a premature leak in the failing underlayment that the homeowner had no idea existed. Two days after the install, he texted us to say his HVAC system was running less and his attic was 30 to 40 degrees cooler. This case study covers the full installation process, what we found, and everything you need to know about attic ventilation as a South Florida homeowner.

Quick Summary

BLU Roofing installed a Solatube RM2400 solar-powered attic fan on an 18-year-old three-tab shingle roof in Boynton Beach. During the installation, we discovered that the existing 30-pound felt underlayment was failing and moisture had already begun entering the roof system. We replaced the compromised underlayment with Polyglass TU Plus self-adhered membrane, properly waterproofed the fan base flashing, and completed the installation. Two days later, the homeowner confirmed his attic was 30 to 40 degrees cooler and his HVAC system was running less.

Why Attic Ventilation Matters in South Florida

In South Florida, an unventilated or poorly ventilated attic is not just uncomfortable, it is actively damaging your home. When attic temperatures reach 147 degrees, as they did in this Boynton Beach home, the heat radiates down through the ceiling insulation and into the living space, forcing the HVAC system to work harder and longer to maintain a comfortable temperature. Over time, extreme attic heat also accelerates the degradation of roofing materials, shortening the lifespan of shingles and underlayment from the inside out.

The damage is not limited to the summer months. During South Florida’s cooler, more humid season, a poorly ventilated attic traps moisture from everyday household activities, including showers, cooking, and humidifiers. That trapped moisture condenses on the underside of the roof deck, leading to mold growth, insulation degradation, and over time, structural decay in the framing. Active attic ventilation addresses both problems year-round.

The financial case is equally compelling. A cooler attic reduces the heat load on your HVAC system, which translates directly into lower monthly energy bills. It also extends the life of your air conditioning equipment, which is working against a smaller temperature differential when the attic above it is not superheated. For Palm Beach County homeowners, where air conditioning runs for the majority of the year, the long-term savings from proper attic ventilation are significant.

Passive vs. Active Ventilation: What Is the Difference?

This Boynton Beach home already had a rolled ridge vent installed when we arrived. Ridge vents are a form of passive ventilation: they rely on natural convection, warm air rising and escaping through the ridge while cooler air is drawn in through soffit vents at the eaves. When a roof system is well-balanced and the attic is properly sealed, passive ventilation can be effective. In many South Florida homes, however, the passive exchange is minimal, particularly during the peak heat hours of the day when outside temperatures are also at their highest and the temperature differential driving convection is reduced.

An active solar-powered attic fan like the Solatube RM2400 forces hot air out of the attic mechanically, regardless of outside temperature or wind conditions. It does not rely on convection or wind. It runs whenever the sun is shining on the solar panel, which in South Florida means it is working during the exact hours when attic heat is at its worst. The result, as this homeowner experienced, is a measurable and immediate reduction in attic temperature.

It is important to note that a solar attic fan and a ridge vent are not mutually exclusive. When installed correctly, with the fan positioned well below the ridge, the two systems can actually work together. The fan exhausts hot air from the central attic space while the ridge vent handles the area immediately at the peak. Placing the fan too close to the ridge would cause it to short-circuit, pulling air in through the ridge vent rather than drawing it up from the lower attic. Proper placement and soffit intake are the most critical parts of every installation we perform.

Choosing the Right Location for the Fan

Placement of an attic fan is not arbitrary. For this installation, we selected a central location on the roof, well below the existing rolled ridge vent, to maximize the volume of attic air the fan would draw through before exhausting it. A fan placed too close to the ridge pulls air from a very small zone near the peak rather than ventilating the full attic volume.

Before cutting any opening, we also verified from inside the attic that the chosen location fell cleanly between two roof trusses. Cutting into a truss would compromise the structural integrity of the roof framing, and this is a non-negotiable check on every attic fan installation we perform. We confirmed a perfect placement between trusses before proceeding with the opening.

The Surprise Discovery: A Premature Leak

Once we opened the roof at the selected location, we found something the homeowner was not expecting. The existing underlayment, a single layer of 30-pound felt, was already compromised. There was a visible tear in the paper right at the opening, and when we removed the felt and the tin caps securing it, the plywood beneath was wet in several areas. Moisture had already begun entering the roof system.

This is a common condition on 18-year-old roofs with 30-pound felt underlayment. Over time, felt paper becomes brittle, loses its flexibility, and develops cracks and tears, particularly around fastener points and in areas of thermal movement. The shingles above may still look acceptable from the ground, but the underlayment beneath them, which is the true waterproofing layer of the system, can be failing silently. In this case, opening the roof for the fan installation revealed a premature leak that, left unaddressed, would have eventually caused visible interior damage. Adding to this the roof will probably be replaced in the next couple of years.

We replaced the compromised section of underlayment with Polyglass TU Plus self-adhered membrane, tying it into the existing roof system with Bolle roof cement and cotton membrane to create a proper, water-tight transition. This is the same material and method we use on full roof replacements, applied surgically to the affected area. The homeowner essentially received a free leak repair as part of the fan installation, simply because we opened the roof in the right place at the right time.

The Installation Process: Step by Step

A proper solar attic fan installation is not just drilling a hole and dropping a fan in. Done correctly, it involves integrating the fan base flashing into the existing roof system with the same waterproofing standards we apply to any roof penetration.

  1. Determine the fan location, keeping it well separated from the existing ridge vent and confirming the opening falls between trusses. We bounce on the roof a bit and can tell when we’re on a truss or in-between them. This comes with experience.
  2. Remove the shingles in the work area to expose the underlayment.
  3. Remove the existing 30-pound felt and tin caps. In this case, the felt was already compromised and showing signs of moisture intrusion.
  4. Cut the circular opening through the plywood roof deck, sized precisely for the Solatube RM2400 base flashing, with perfect placement confirmed between trusses.
  5. Install new Polyglass TU Plus self-adhered underlayment, tying it into the existing roof system with bull roof cement and cotton membrane around the full perimeter of the repair area.
  6. Apply bull underneath the fan base flashing as an additional sealant layer before nailing the base down. This step seals the nail penetrations from below as the base is fastened, ensuring the new roof penetration remains water-tight.
  7. Nail the fan base flashing into the roof deck at the proper fastening schedule per the applicable Florida product approval.
  8. Apply bull and cotton membrane over the top of the base flashing to seal all nail heads and create a fully water-tight installation.
  9. Install new shingles around the fan base, using the best available color match to the existing three-tab shingles.
  10. Install the Solatube RM2400 fan unit onto the base and secure it per the manufacturer’s specifications.
  11. Perform a thorough clean up of the work area.

About the Solatube RM2400: Full Product Overview

The Solatube RM2400 is Solatube’s most powerful roof-mounted solar attic fan. It is powered by an industry-leading 33-watt solar panel, which drives a high-speed motor engineered for ultra-low vibration and sound. It operates entirely on solar power with no wiring required and no ongoing electrical operating cost after installation.

The optional ClimaSense upgrade adds temperature and humidity sensing to the system, allowing the fan to continue ventilating for up to 4 hours after the sun sets. This is particularly valuable during South Florida’s humid evenings, when attic moisture levels can remain elevated long after temperatures drop. The ClimaSense controller lets you set your own temperature and humidity thresholds so the fan responds automatically to your attic’s specific conditions.

For homeowners who want a simpler automation option without the full ClimaSense upgrade, Solatube also offers a Thermal Switch add-on that activates the fan automatically when attic temperatures reach 85 degrees Fahrenheit and shuts it off when temperatures drop below 65 degrees. This is a cost-effective way to add temperature-controlled operation to any RM2400 installation.

The RM2400 carries a 10-year manufacturer’s warranty and has a typical life expectancy of 10 to 15 years or longer depending on conditions. The benefits extend beyond the summer months. During South Florida’s cooler, more humid season, an active attic fan equalizes interior and exterior temperatures, which helps prevent moisture accumulation, mold growth, and the insulation and framing damage that excess humidity can cause over time.

Solatube Model Comparison

Solatube offers several attic fan models to suit different attic sizes and installation requirements. Here is a quick comparison of the options most relevant to South Florida homeowners:

Model Solar Panel Best For ClimaSense Available
RM 2400 33 watts Large attics, maximum ventilation power Yes
RM 1500 16 watts Smaller attics, sheds, open-ceiling garages Yes
IM 1500 16 watts Interior mount, converts existing passive gable or dormer vents Yes

For most standard South Florida homes with a full attic, the RM2400 is the right choice. Its 33-watt panel delivers the maximum airflow needed to make a meaningful difference in a large, superheated attic space. The RM1500 is better suited for smaller spaces like a garage or a shed where a full-power unit would be more than necessary.

Florida Building Code and HVHZ Compliance

For Florida homeowners, product approval is not optional. Any roof penetration, including an attic fan, must be installed using a product that carries a valid Florida Product Approval number or a Miami-Dade Notice of Acceptance (NOA) for properties in High Velocity Hurricane Zone (HVHZ) jurisdictions.

The Solatube RM2400 is available in two mounting profiles that address the full range of Florida requirements. The Low Profile Roof Mount meets Florida Building Code (FL10884) and is appropriate for most pitched roof applications outside of HVHZ. The High Profile Roof Mount is aerodynamically engineered for locations with heavy winds and tropical storms, and it meets Florida Building Code HVHZ requirements (FL14826) as well as Miami-Dade standards. BLU Roofing always installs the correct profile for the jurisdiction and follows the applicable product approval method for every installation.

A note on flashing: depending on the applicable approval and jurisdiction, the exposed lower portion of the fan flashing may extend farther over the shingles than what is visible in some installations. The important factor is that the fan base, flashing, underlayment, and shingles are integrated correctly so the new roof penetration remains properly waterproofed and code-compliant.

The Result: 30 to 40 Degrees Cooler in 48 Hours

The fan was installed on a Saturday. On Monday, two days later, the homeowner sent a text confirming that his attic was 30 to 40 degrees cooler and that his HVAC system was noticeably running less. He noted that Monday was one of the hottest days on record, likely hotter than the day of the install, which makes the result even more significant. A 30 to 40 degree reduction in attic temperature on an extreme heat day is a meaningful improvement in both comfort and energy efficiency, and it happened within 48 hours of installation.

This result is consistent with what Solatube and independent testing have documented for active solar attic ventilation. The combination of a 33-watt solar panel, a high-efficiency motor, and proper placement in the attic creates a system that makes a real, measurable difference in the homes where it is installed.

Frequently Asked Questions

Do solar attic fans only work while the sun is shining?
The standard RM2400 operates during daylight hours when the solar panel is generating power. With the optional ClimaSense upgrade, the fan can continue ventilating for up to 4 hours after the sun sets, providing cooling and humidity control into the evening.

Will a solar attic fan work with my existing ridge vent?
Yes, as long as the fan is positioned well below the ridge and other criteria are met- Please consult a roofing contractor that knows about ventilation. Placing the fan too close to the ridge would cause it to pull air in through the ridge vent rather than exhausting hot air from the lower attic. Proper placement is part of every BLU Roofing installation.

Can a solar attic fan be installed on a tile roof?
Yes. Solatube offers a proprietary tile roof flashing profile that integrates seamlessly with the tile structure. The installation method is basically the same as a shingle installation, and the waterproofing principles are the same.

How long does the installation take?
A standard Solatube RM2400 installation on a shingle or teile roof typically takes one day, including any underlayment repair work. Metal roofs will be a 2 day process as to get new panels fabricated.

What if my roof has a lot of shade from trees?
Shade can reduce the solar panel’s output and limit the fan’s performance. Solatube offers an RM1500 Add-On Panel that can supplement the system when shadows limit sun exposure. If your roof is heavily shaded, we can discuss whether a solar fan is the right solution for your specific situation. The fan runs in the shade too.

Is a permit required for a solar attic fan installation in Palm Beach County?
Permit requirements vary by municipality. BLU Roofing follows all applicable local code requirements and can advise on permitting for your specific location in Palm Beach County.

If you are interested in a Solatube RM2400 installation for your Boynton Beach or Palm Beach County home, contact Peter Menke at 561-379-5364 for a free consultation. We will assess your attic, recommend the right product, and ensure the installation is done correctly from the waterproofing up.

Loxahatchee metal roof repair

Case Study: Loxahatchee Metal Roof Repair on a Standing Seam Snaplock Roof

Metal roofs are often marketed as low-maintenance and long-lasting, and for the most part, that is true. But even the best metal roof system has one vulnerability: the penetrations. Wherever something passes through a metal roof, whether it is a pipe, a vent, or an electrical mast, the seal around that penetration is only as good as the installation. On a recent job in Loxahatchee (The Acreage) in Palm Beach County, we found an 8-year-old standing seam snaplock metal panel roof that had likely been leaking for years, all because of a zipper boot that was installed without caulking or butyl tape underneath it. This case study walks through the full diagnosis and repair.

Quick Summary

BLU Roofing completed a Loxahatchee metal roof repair on an 8-year-old 1-inch standing seam snaplock metal panel roof in The Acreage. The leak originated at the electrical mast penetration, where a zipper boot had been installed with no caulking and no butyl tape underneath it. The repair required removing the ridge caps, Z channel, two panels, and damaged underlayment, replacing rotted plywood decking, installing new Polyglass TU Plus underlayment, fabricating two custom-matched replacement panels, and reinstalling everything with proper sealing at the boot.

The Root Cause: A Zipper Boot with No Seal

When we arrived at this Loxahatchee property, the homeowner had been dealing with a persistent leak near the electrical mast for some time. On a standing seam metal roof, the electrical mast passes through the roof deck and is sealed with a rubber fitting called a zipper boot. This boot is designed to create a water-tight seal around the mast and prevent any moisture from entering the roof system at that penetration point.

When we removed the old zipper boot, the cause of the leak was immediately obvious. There was no caulking underneath the boot, and no butyl tape anywhere on the installation. Butyl tape is a butyl-based, self-adhering tape used to create a secondary seal between the boot flange and the metal panel surface. Without it, and without caulking beneath the boot, the only thing keeping water out was the physical pressure of the boot flange sitting on the panel, which is not a reliable seal in South Florida’s heavy rain environment. Water had been finding its way underneath the boot and into the roof system for what appeared to be a significant portion of the roof’s 8-year life.

What Is a Zipper Boot and Why Does It Matter?

A zipper boot, sometimes called a pipe boot or mast boot, is a rubber or silicone fitting that slides over a pipe or mast penetrating through a roof and seals the opening. On a standing seam metal roof, the boot must be properly sized to the mast diameter, set with a butyl or silicone caulk bead underneath the flange, and secured with butyl tape around the perimeter to ensure a complete, water-tight seal.

This is not a complex installation, but it requires attention to detail. A boot installed without the proper sealants underneath it may look correct from the outside but will allow water to migrate under the flange during wind-driven rain. On a metal roof, where water can travel significant distances horizontally before finding a path downward, a small unsealed penetration can cause damage far from the visible entry point.

The Scope of Damage: Years of Hidden Water Intrusion

Once we removed the two metal panels adjacent to the mast, the extent of the damage became clear. The underlayment beneath the panels consisted of two layers of 30-pound felt topped with Polyglass TU Plus, but the long-term water intrusion had compromised the plywood roof decking beneath it. The rot was significant enough that we could tell this had not been a recent leak. The decking had been absorbing moisture for an extended period.

We also noted something unusual during the panel removal: there were no screws in one of the panels for approximately the first four feet up from the eave. This is a detail worth flagging, as proper fastening of standing seam panels is critical to maintaining the wind resistance of the system. A panel that is not properly secured at the base is more susceptible to uplift during high-wind events.

The Repair Process: Step by Step

Repairing a standing seam metal roof requires a different approach than tile or shingle work. The panels interlock with one another, meaning you cannot simply replace one section without carefully disassembling the surrounding system and sourcing panels that match the original profile exactly.

  1. Remove the ridge caps and Z channel by unscrewing them to access the top of the affected panels.
  2. Remove the old zipper boot and document the absence of caulking and beetle tape as the primary failure point.
  3. Remove the two affected metal panels, carefully unscrewing and unsnapping them from the standing seam system.
  4. Remove the damaged underlayment, exposing the rotted plywood decking beneath.
  5. Cut out and replace the rotted 5/8-inch plywood with new decking, restoring the structural integrity of the roof deck. The work area was covered during a brief rain event to protect the open deck, which is standard practice for Florida weather conditions should a rain shower pop up.
  6. Install new Polyglass TU Plus underlayment, matching the existing system and rolling it from the top of the ridge all the way down to the eave across the full width of the two removed panels.
  7. Take an original panel to a metal fabricator to have two custom-matched replacement panels fabricated to the exact profile, width, and finish of the existing roof system.
  8. Measure, cut, and install the new panels, screwing them down at the proper fastening schedule and snapping them into the standing seam locks on either side.
  9. Install the new zipper boot with a full bead of caulk underneath the flange and beetle tape around the entire perimeter, creating the proper water-tight seal that was missing from the original installation.
  10. Reinstall the Z channel and ridge caps and perform a thorough clean up of the work area.

What Loxahatchee Metal Roof Owners Should Know

Standing seam metal roofs are an excellent choice for The Acreage and surrounding Loxahatchee properties. They are durable, wind resistant, and when properly installed and maintained, can last 40 to 50 years. However, the penetrations in any metal roof system are the most vulnerable points, and they deserve regular attention.

If your home has an electrical mast, plumbing vents, or any other penetration through a standing seam metal roof, it is worth having a professional inspect the boots and seals around those penetrations, especially if the roof is more than five years old. A failed boot seal is an inexpensive repair when caught early. Left unaddressed, as this case demonstrates, it can result in significant plywood replacement and panel fabrication costs that far exceed the cost of a simple re-seal.

If you have noticed any signs of a leak, a water stain on your ceiling, moisture in your attic, or discoloration around a penetration on the roof surface, contact Peter Menke at 561-379-5364 for a professional inspection.

Westlake roof leak repair

Case Study: Westlake Roof Leak Repair on an 8-Year-Old Concrete Tile Roof

When an 8-year-old roof is already leaking, the first question any homeowner should ask is not just “where is the water coming in?” but “why is this happening so soon?” On a recent job in The Hammocks of Westlake, near Loxahatchee in Palm Beach County, we found the answer, and it is a systemic issue affecting multiple homes on the same block. This case study walks through how we tracked down a complex leak over a garage, what we found in the attic, and why the original construction method is at the root of the problem.

Quick Summary

BLU Roofing completed a Westlake roof leak repair on an 8-year-old concrete tile roof in The Hammocks of Westlake. The root cause was mechanically fastened (screwed-in) tile installed over a single layer of peel-and-stick underlayment, a system that becomes vulnerable over time as tile movement loosens the screw holes. The repair involved removing rotted plywood, installing new decking, applying CertainTeed SA Granulated cap sheet, reinforcing the valley and return flashings, and re-foaming the tiles. The homeowner called Friday, the proposal was approved Monday, and the repair was completed Wednesday.

  4. The Repair Process: Step by Step
  5. What Westlake Homeowners Should Know

The Roof Detail: Why This Area Was High-Risk

The section of the roof above the garage was not a simple flat run of tile. It included a bottom valley, a roof-to-wall return flashing, and a cricket, a small peaked structure designed to divert water away from a vertical wall. These are all high-flow water areas, meaning during a South Florida rainstorm, large volumes of water converge in these zones before draining off the roof. Any weakness in the waterproofing system in these areas will be found by water, and it will be found quickly.

When a roof has multiple complex details concentrated in one area, as this garage section did, the margin for error in both the original installation and the long-term performance of the system becomes very small. This is exactly why these zones require extra layers of waterproofing protection, not just the base system used on the open field of the roof.

The Root Cause: A Single-Ply System with Mechanical Fasteners

This roof was built with mechanically fastened (screwed-in) concrete tile installed over a single layer of self-adhered (peel-and-stick) underlayment. In Peter Menke’s experience, this is a system that is more susceptible to premature leaks than two alternative approaches: mechanically fastened tile over a two-ply underlayment system, or foam-set tile over a single-ply system.

Here is why the single-ply, screw-in combination is problematic. Concrete roof tiles are not completely rigid once installed. Over time, as the structure settles, as temperatures fluctuate, and as wind loads are applied during storms, the tiles move slightly. Each time a tile shifts, even a fraction of an inch, the screw that penetrates the only layer of underlayment you have works that hole a little wider. Over 8 years, those screw holes can loosen enough to allow water to migrate underneath the tile and directly through the underlayment.

This is not a theory. This is the fourth or fifth leak on the same block in The Hammocks of Westlake, and the leaks have been in different locations on different roofs. This is not one bad spot on one roof, it is a pattern across an entire subdivision, pointing directly to the original construction method as the systemic cause.

The solution, both for new construction and for repairs, is straightforward. If you are using a single-ply underlayment system, use roof tile adhesive (foam) to set the tiles, not screws. This eliminates the penetration through the underlayment entirely. It is equally important, if not more important, to add a second layer of waterproofing in all high-flow water areas: valleys, returns, crickets, roof-to-wall flashings, around all roof penetrations, and along the perimeter eaves. Doubling the protection in these zones is what separates a roof that lasts 30 years from one that leaks at year 8.

Finding the Leak: Starting in the Attic

Rather than guessing which of the several complex details above the garage was the entry point, we went straight to the attic. Tracing a leak from the inside is the most reliable way to identify the true source, especially when multiple roof details converge in one area. In the attic, we were able to pinpoint exactly where the water was entering and follow the trail back to the roof deck.

What we found confirmed the diagnosis. There was a crack in the underlayment paper at the screw penetration, and directly beneath it, a visible gap in the plywood roof decking. That gap was consistent with a new construction defect, the kind of issue that goes unnoticed for years until water finds it. The combination of the compromised underlayment and the gap in the decking had allowed moisture to sit against the wood long enough to cause rot.

The Repair Process: Step by Step

Once the source was confirmed, the repair followed a precise sequence designed to restore the full waterproofing integrity of the system.

  1. Inspect the attic to trace the leak back to its source on the roof deck.
  2. Carefully remove the concrete roof tiles without breaking any. The homeowner had no spare tiles, so preserving every one was essential.
  3. Remove the old underlayment and damaged roof decking, cutting out the rotted plywood and replacing it with new material.
  4. Reinforce the surrounding waterproofing details, including the bottom of the valleys and the return flashing, to address the high-flow water zones that contributed to the failure.
  5. Install CertainTeed SA Granulated cap sheet underlayment and tie it into the existing roof system using roof cement with reinforcing cotton membrane, creating a seamless, water-tight connection.
  6. Reinstall the roof tiles using ICP two-part polyurethane roof tile adhesive, no new screw penetrations through the fresh underlayment.
  7. Perform a thorough clean up of the work area, leaving the property in better condition than when we arrived.

The homeowner called on a Friday evening. We inspected the roof Monday morning, the proposal was approved Tuesday, and the repair was completed Wednesday.

What Westlake Homeowners Should Know

If you live in The Hammocks of Westlake or a nearby community built with mechanically fastened concrete tile over a single layer of peel-and-stick underlayment, this case study is directly relevant to your home. You do not need to wait for a ceiling stain to take action. A professional roof inspection can identify whether your high-flow water areas have adequate waterproofing protection before a leak develops.

The most important thing to understand is that a leak on a relatively new roof is not necessarily a sign of a catastrophic problem. In many cases, like this one, it is a localized failure that can be repaired surgically, preserving the existing roof system and avoiding a premature full replacement. The key is catching it early, before water has time to cause widespread rot in the decking.

If you have noticed a ceiling stain, experienced a leak after heavy rain, or simply want peace of mind about your roof’s waterproofing system, contact Peter Menke at 561-379-5364 for a professional inspection. BLU Roofing serves Westlake, Loxahatchee, and all of Palm Beach County with honest assessments and repairs that are built to last.
