This page is for Orlando homeowners who’ve got GAF shingles on their roof and want straight answers about how they fail, what fixes cost, and who they’re letting through the door. We’re an independent GAF service provider, not a factory warranty crew, which means we can tell you when a repair makes sense and when you’re better off replacing instead. Grant Whitlock, our owner, trained on roofs in Los Angeles and has put in nearly two decades of hands-on work, including plenty of GAF systems across Lake Nona and the wider Orlando area.

How GAF Products Fail – and How We Fix Them

Every shingle brand has its own habits. Here’s what we actually see on GAF roofs in Orlando, and what we do about it.

• Timberline HDZ granule shedding in the first five years. GAF’s Timberline line is everywhere in Orlando, and we regularly see granule loss that has nothing to do with age. It’s usually a manufacturing variance in the asphalt mix, not storm damage. The granules wash to the gutter line, leaving dark patches on the shingle face. Our fix is a targeted replacement of the affected slopes, and we’ll document what we find so you have a record for any future warranty conversation with GAF.
• Seal strip failure on Timberline Natural Shadow after high humidity cycles. Orlando’s heat and humidity cause the adhesive strips on older Natural Shadow shingles to lose tack, especially on north-facing slopes that never fully bake dry. Shingles lift, wind gets underneath, and you lose coverage. We hand-seal the lifted tabs with a compatible asphalt adhesive rather than nailing through the shingle face, which would void the GAF wind warranty. A roof shouldn’t be a mystery, and this is one of those fixes that looks simple but has a right way and a wrong way.
• Clogged Deck-Armor drainage at valley intersections. GAF Deck-Armor underlayment is woven to be breathable, but it can catch and hold fine debris at valley transitions, especially under oak canopies in Orlando neighborhoods like College Park. Water backs up, and the underlayment degrades early. We remove the valley shingles, clear and reset the underlayment, and replace the valley metal before reinstalling. It’s a half-day job that prevents a full valley rebuild later.
• Leak-barrier gaps at roof-to-wall joints on GAF Ridge Cap installations. GAF Seal-A-Ridge cap shingles are great when installed correctly, but we find homes in Orlando where the installer skipped the leak barrier at the roof-to-wall transition. The first rain after a humid stretch pushes water under the cap line. We pull the cap, install a proper barrier strip, and reset the ridge. This is one of the most common GAF-specific callbacks we fix.
• Improper starter-row placement causing shingle curl on Timberline UHDZ. GAF’s UHDZ is a thicker, high-definition shingle that demands a properly offset starter row. When it’s not placed right, the bottom edge of the shingle doesn’t sit flat, and curl develops within two years. We pull the first course, reset the starter row, and re-lay the shingles. It’s a repair that restores the look of a new roof without a full replacement.

Our GAF Roofing Company Process

Here’s how a GAF job works when you call Mercer Roofing Co Orlando.

1. 1
   You call (850) 757-3564 and get a live person. We answer the phone. You tell us what’s going on, and we schedule a visit.
2. 2
   You get the technician’s name and photo before we arrive. Every tech is background-checked and identity-verified under Threshold Verified standards. You’ll know exactly who’s at your door, and they’ll badge in with a photo ID.
3. 3
   We diagnose on-site. We inspect the GAF roof, identify the specific failure, and decide whether it’s repair or replacement territory. If repair, we determine whether OEM GAF components or quality aftermarket replacements are the better call, and we explain why.
4. 4
   You get a written price before any work starts. No work begins without that written number in your hand. If the job changes, we stop and re-quote before proceeding. There’s no such thing as “the invoice came in higher.”
5. 5
   We do the work and test it. We fix the roof, run water where we can, verify the seal lines, and clean up the site.
6. 6
   You get the 365-Day Done Right Promise in writing. Every repair includes a written guarantee. If it fails within a year, we come back and make it right, free. That’s not a courtesy; it’s our standard.

Why Orlando Homeowners Call Mercer Roofing Co Orlando for GAF Work

Most roofers can put shingles on. The difference is what happens before and after. Every one of our technicians is background-checked, identity-verified, and uniformed, and we send their name and photo to you before they arrive.

Beyond that, we know GAF roofs specifically. If you’ve got GAF and it’s failing, we can fix it right. If you want to move to a different brand like Owens Corning or CertainTeed, we’re certified to install those too, and we’ll give you an honest comparison. And every job, repair or replacement, carries our 365-Day Done Right Promise in writing.
