Why Fort Lauderdale Homeowners Choose CertainTeed Roofing
Mercer Roofing Co Fort Lauderdale provides independent CertainTeed roofing repair, service, and full replacement across Broward County through our Fort Lauderdale Certainteed service, with deep hands-on experience in the Landmark, Landmark PRO, Presidential Shake, and XT 25 lines. We’re not a manufacturer-authorized dealer, and we say that plainly because it matters: our recommendations come from thousands of real repairs on South Florida roofs, not a brand playbook. Our CertainTeed work is different because every technician who arrives at your door has been background-checked, identity-verified, and badged under the Threshold Standard, and every price is put in writing before a single shingle comes off your roof.
If you own a CertainTeed roof in Fort Lauderdale and you’re seeing granule loss, lifted shingles, or interior stains after a storm, call (754) 354-1224. We’ll diagnose it honestly and tell you whether a repair will hold or whether replacement makes better financial sense.
Why Trust Mercer Roofing Co Fort Lauderdale for Your CertainTeed Roofing?
CertainTeed shingles behave differently in South Florida than they do in other parts of the country, and our techs know exactly what that means for your roof. We’ve pulled back enough Landmark PRO courses in Coral Ridge, Rio Vista, and Las Olas Isles to know where these shingles fail first, and we’ve applied that same field knowledge to our Certainteed service in Pompano Beach, how the granule blend holds up under a Fort Lauderdale summer, and what a warranty-safe repair actually requires. Owner Grant Whitlock brought his construction technology training from Los Angeles Trade-Technical College into more than two decades of roofing work, and he and our crew have served Fort Lauderdale for years, handling everything from flat membrane repairs near Las Olas Boulevard to full tile replacements on older residential homes throughout Broward County. When we service a CertainTeed roof, we’re working with knowledge earned on actual job sites, not classroom theory.
We also understand that inviting a roofing contractor to your home means opening your door to someone you don’t know. So before any Mercer technician arrives, you receive their name and photo. They show up in a clean, marked uniform, present a photo ID badge at the door, and never start work without a written price in your hand. For homeowners who are often alone during the day, parents with young children, or older Fort Lauderdale residents who want certainty about who’s on their property, that’s not a nice-to-have. That’s the reason they call us.

Common CertainTeed Roofing Problems We Fix in Fort Lauderdale
These aren’t generic roofing issues. These are the failure points we see repeatedly on CertainTeed products in Fort Lauderdale’s subtropical, hurricane-exposed climate:
- Sealant strip failure at drip edges on Landmark roofs. Fort Lauderdale’s thermal cycling, hot days followed by cool nights and heavy rain, causes the factory sealant strip on CertainTeed Landmark architectural shingles to lose adhesion at the roof’s edges. When that happens, wind gets under the bottom course and peels shingles upward. We see this most often on homes within a few blocks of the ocean, where sustained wind exposure is worst. The fix is a hand-sealing process that re-bonds the shingles to the starter strip, using a sealant compatible with CertainTeed’s asphalt composition.
- Nail pops and back-outs from the original install. This is the one homeowners rarely notice until water is already in the house. When a shingle is nailed too high on the nail line, or too shallow, the thermal expansion and contraction of the roof deck in Fort Lauderdale humidity slowly works the nail back out. The nail head pushes against the shingle above it, creating a tiny puncture that becomes a leak path into the decking. We find these on Landmark and Landmark PRO roofs that looked fine from the ground for years. Repairing them correctly means removing the affected shingle, checking the deck beneath, and re-nailing on the proper line, not just caulking the nail head.
- Starter strip slippage on steep pitches. CertainTeed roofs on steep Fort Lauderdale townhome and Mediterranean-style villa pitches sometimes suffer from starter strip shingles that weren’t embedded firmly at the eave line. The starter strip is the foundation course, and when it slips, it exposes the bottom edges of the first full course to wind-driven rain. In Coral Ridge and Rio Vista, where steep gable ends are common, we’ve found slipped starter strips on roofs less than eight years old. We re-set or replace the starter course and inspect every fastener along the eave before re-laying the course above.
- Valley metal warping on Presidential Shake roofs. CertainTeed Presidential Shake is a thick, luxurious shingle, but its weight and profile make valley detailing critical. On Fort Lauderdale homes with Presidential Shake, we see valley metal that has warped from the combination of heat, humidity, and the slight movement of the heavy shingles above it. Warped valley metal channels water to the sides instead of down the valley, and water ends up under the shingle tabs. The repair involves replacing the valley metal and re-setting the shingle cuts to match the new profile, keeping the original granule blend intact for appearance.
- Corner cracking on XT 25 3-tab shingles. The XT 25 is an entry-level CertainTeed 3-tab, and in Fort Lauderdale’s intense UV, the corners of these tabs become brittle years before the field of the shingle shows wear. The corners snap off in high wind, leaving ragged edges that catch more wind and begin a cascade. If your XT 25 roof is showing corner cracks, it’s often a signal that the entire field is nearing the end of its service life. We’ll give you a straight answer on that, not a string of patch repairs.
CertainTeed Parts & Our Repair-vs-Replace Approach
When we patch or replace individual courses on a CertainTeed roof, we default to CertainTeed OEM shingles and accessories. Matching the granule blend and profile keeps the roof looking consistent and keeps the manufacturer’s warranty language on solid ground. But we’re honest about where the factory parts don’t cut it in Fort Lauderdale. Underlayment, flashing, and vent boots are areas where we often recommend proven aftermarket upgrades: synthetic underlayment that handles our humidity better than older felt, and stainless steel flashing components that resist salt air corrosion far longer than some factory-spec galvanized options. When we make that recommendation, we explain why, in writing, before we order anything.
Our repair-vs-replace rule is simple and we apply it the same way to every roof we inspect: if 30% or more of a slope has failed, or if the decking feels spongy when we walk it, patching more shingles is throwing good money after bad. We recommend a full replacement with a Landmark PRO system instead. If a repair will genuinely hold, we tell you that too, and we put our 365-Day Done Right Promise behind our Roof Repair services. Call (754) 354-1224 for an assessment of your CertainTeed roof.
Our CertainTeed Service Process – Step by Step
- 1
Diagnosis. We inspect the roof surface, the attic or decking beneath the leak area, and the flashing details. For CertainTeed roofs, we look specifically at sealant strip adhesion, nail placement lines, starter strip integrity, and valley metal condition. We’ll show you photos of what we find and explain what each issue means in plain English.
- 2
Repair or install. For repairs, we use CertainTeed OEM shingles and accessories wherever the warranty and appearance depend on it, and upgraded components where Fort Lauderdale conditions demand more. For replacement, we strip to the deck and inspect the wood before any new material goes down, replacing soft or damaged decking as needed and re-nailing everything to meet Broward County wind-load requirements.
- 3
Test. After the work is complete, we water-test the repaired area or run a visual and tactile inspection across the entire installation, checking every seam, valley, and penetration. If anything doesn’t meet our standard, it gets corrected before we call the job done.
- 4
Warranty. Every repair includes a written guarantee, and our 365-Day Done Right Promise means if it’s not right within a year, we make it right. You’ll have a written record of exactly what was done, what parts were used, and what the guarantee covers. No verbal reassurances, no fine print surprises.

AfterCertainTeed Products We Service & Install in Fort Lauderdale
Our techs work across the CertainTeed residential lineup most common in Broward County.

We also handle Presidential Shake for high-end homes that want the look of wood shake without the rot, and XT 25 3-Tab Shingles on older ranch homes and rental properties. We keep common CertainTeed Landmark color blends available locally for fast patch matching, and we can source any CertainTeed product line through our regular supplier network within days, not weeks.

We Also Service These Brands
Mercer Roofing Co Fort Lauderdale is not tied to a single manufacturer’s product line. We work with GAF and Owens Corning shingles on a regular basis, and we carry the experience to repair or replace roofs from all major shingle brands. That matters because it means our CertainTeed recommendations aren’t born from brand loyalty. They’re born from what actually holds up on a Fort Lauderdale roof.
FAQs – CertainTeed Roofing Service in Fort Lauderdale
No. We are an independent roofing contractor with significant experience servicing CertainTeed products in Fort Lauderdale, but we are not an authorized CertainTeed dealer or service provider. That independence is deliberate: we recommend what works, not what a manufacturer program dictates. All of our work is supported by our own written guarantees and our 365-Day Done Right Promise. Call (754) 354-1224 and we’ll tell you what your CertainTeed roof needs, without any brand agenda.
Yes, for shingle replacement and patching, we default to CertainTeed OEM shingles and accessories to preserve the granule blend match and keep the manufacturer’s warranty intact. For underlayment, flashing, and vent boots, we may recommend aftermarket upgrades like synthetic underlayment or stainless steel components that hold up better in Fort Lauderdale’s salt air and humidity. We explain any material substitution in writing before work begins.
Most CertainTeed repairs in Fort Lauderdale are completed in one visit, typically four to eight hours depending on access and weather, and our CertainTeed Roofing in Sunrise, FL follows the same efficient schedule. Full roof replacements using CertainTeed products generally take two to four days for an average single-family home. We’ll give you a written timeline when we provide your estimate, and we’ll call you if anything changes. Call (754) 354-1224 to schedule a time for us to assess your roof.
We service and install Landmark Architectural, Landmark PRO Architectural, Presidential Shake, and XT 25 3-Tab shingles. We also handle related work including roof decking replacement, tile underlayment replacement, and flat roof patch transitions where they connect to existing CertainTeed asphalt shingle sections. If you’re not sure which CertainTeed line is on your roof, we’ll identify it during the inspection.
No. Using CertainTeed OEM shingles and accessories for repairs keeps the manufacturer’s warranty intact, and we document every material and method in writing. The more common way homeowners lose warranty coverage is by having unlicensed or inexperienced crews perform work with incompatible materials. We follow CertainTeed’s published installation guidelines for every repair we perform, and our 365-Day Done Right Promise stands independently of the manufacturer’s warranty. Call (754) 354-1224 if you’re concerned about your warranty status.
CertainTeed roof service in Fort Lauderdale generally ranges from $350 to $1,800 for common repairs like shingle replacement, sealant strip repair, or valley metal replacement, while full CertainTeed roof replacement on an average single-family home typically runs $14,000 to $32,000 depending on product line, roof size, decking condition, and access. Here’s how those numbers break down in this market:
- Shingle repair or patch: $350 – $900
- Valley metal replacement: $650 – $1,800
- Decking replacement (per sheet): $85 – $140
- Landmark full replacement: $14,000 – $24,000
- Landmark PRO full replacement: $17,000 – $28,000
- Presidential Shake replacement: $22,000 – $32,000
These are real ranges based on Fort Lauderdale labor and material costs, not national averages. The only way to know your specific number is to have someone walk your roof and look at what’s actually there. That’s what we do. Call (754) 354-1224 for a free estimate, and you’ll have a written price before any work is scheduled.
In Fort Lauderdale’s subtropical climate, CertainTeed Landmark architectural shingles typically last 15 to 20 years, compared to the 25 to 30 years they might reach in a drier, cooler climate. The biggest lifespan shorteners here are UV degradation of the asphalt, salt air exposure, and repeated thermal cycling that breaks down the sealant strip. If your home is within a few blocks of the ocean, expect the shorter end of that range. If the roof has proper attic ventilation and was installed with six nails per shingle, it’ll hold up better. Call (754) 354-1224 and we’ll tell you honestly where your roof falls on that curve.
You usually can’t tell from the ground, which is why you should have the roof inspected after any named storm passes through Fort Lauderdale. Wind damage to Presidential Shake often shows up as lifted tabs that settle back down after the wind stops, or as broken adhesive bonds along the shingle’s thick profile that you can only feel by gently pressing along the tab edges. We’ve also seen valley metal warping from the shingle’s weight shifting during the storm. If you’ve got interior water stains or even just a hunch, it’s worth a professional look. Estimates are free: (754) 354-1224.
You can replace one slope, and we do it regularly when the rest of the roof has life left in it. The main issue is color matching: CertainTeed’s granule blends vary slightly between production runs, so a brand new bundle may not match a roof that’s been in Fort Lauderdale sun for eight years. We’ll source the closest available blend and show you a sample before we commit. If the slope is on the front of the house and the mismatch will be obvious, we’ll tell you that plainly and let you decide. Call (754) 354-1224 for an honest assessment.
Corner cracking on Landmark shingles is almost always caused by UV embrittlement and thermal stress, made worse by Fort Lauderdale’s intense sun and humidity swings. The corners of the tabs lose their flexibility first, then break off in high wind. As for warranty coverage, it depends on the age of the roof and the specific warranty terms CertainTeed issued at purchase. Most material warranties cover manufacturing defects, not UV aging, but we’ve seen claims approved for early-life cracking. We can document the condition and help you understand your options. Call (754) 354-1224 and we’ll walk you through it.
Transitions between pitched CertainTeed shingle sections and flat roof patches are where leaks happen most often in Fort Lauderdale, because the junction sees both wind-driven rain and standing water. We build the transition with additional underlayment lapped in the correct direction, a properly embedded flashing detail, and, where appropriate, stainless steel components that resist the salt air. We’ve done this work on flat concrete and membrane sections throughout Broward County, and we detail it the same way every time: with enough overlap that water has no path in. Call (754) 354-1224 to have your transition inspected.
