CertainTeed Roof Repair in Orlando: What to Know First
CertainTeed roof repair in Orlando typically runs $350 to $900 for shingle replacement, leak repair, and flashing work, with most jobs completed in a single visit. We’re an independent CertainTeed service provider in Orlando, not a manufacturer affiliate, which means we repair your roof the way it should be repaired without voiding what’s left of your warranty. If you own a home in Orlando with CertainTeed shingles and you’re seeing stains, granules in the gutter, or daylight in the attic, call (850) 757-3564 and we’ll give you a written price before any work begins.

This page is for Orlando homeowners who want to understand exactly what’s happening on their CertainTeed roof and what a repair should cost. Grant Whitlock, our owner, learned roofing at Los Angeles Trade-Technical College and has spent nearly two decades on residential and commercial projects. He’ll tell you straight: a roof shouldn’t be a mystery. Let’s talk about what’s actually up there.
How CertainTeed Products Fail – and How We Fix Them
Every shingle brand fails in its own way, and CertainTeed is no exception. Here are the five failure patterns we see most often on Orlando roofs, along with what we do about each one.
- Landmark series granule loss around the eaves. CertainTeed Landmark architectural shingles hold up well in Florida sun, but the first three feet of roof edge take the hardest beating from wind-driven rain. When the granules wear thin there, the asphalt beneath oxidizes and the shingle starts to absorb water instead of shedding it. We replace the affected shingles and check the drip edge while we’re up there, because a rusting drip edge will keep causing the same problem.
- Presidential Shake TL splitting at the fastener line. The Presidential Shake TL is a heavier, laminated shingle that looks great on Orlando’s larger custom homes. But its weight means any nail driven slightly off the nail line creates a stress point. After a few years of thermal expansion, the shingle splits right at that fastener. The fix is removing the split shingle, replacing it with a correctly fastened one, and sealing the surrounding tabs. It’s not a job for a general handyman; the sealant and fastener placement have to match CertainTeed’s installation spec or the repair fails at the first summer storm.
- Flashing failures at valleys on XT 25 installations. Three-tab CertainTeed XT 25 shingles are common on older Orlando ranch homes. The shingles themselves are usually fine. What fails is the valley flashing underneath, especially where installers cut corners and didn’t run metal far enough up the valley. Water gets under the shingles at that transition and shows up as a ceiling stain two rooms away from where the leak actually starts. We pull the shingles at the valley, replace the flashing with the correct gauge metal, and re-lay the shingles so water is directed off the roof the way it should be.
- Vent boot gaskets cracking on any CertainTeed roof. This one isn’t brand-specific, but it’s so common on Orlando homes that it deserves a mention. The rubber gasket around plumbing vent pipes dries out and cracks after five to eight years of Florida heat. On a CertainTeed roof, the shingles around the vent are usually still in good shape, which means a $250 vent boot replacement gets you another five years out of the roof instead of a $12,000 replacement. We replace the boot, reseal the shingles around it, and you’re done.
- Membrane failures on CertainTeed Flintlastic flat sections. Many Orlando homes have a flat section over a patio or carport done in CertainTeed Flintlastic SA, a self-adhered modified bitumen membrane. The Florida sun eventually causes the membrane to shrink and pull at the seams, and then water ponds and finds its way through. We cut out the failed section, apply a compatible patching membrane, and re-seal the seams. If the ponding is severe, we’ll talk to you about whether the slope itself needs correction, because no patch survives standing water forever.

Our CertainTeed Roof Repair Process
When you call us about a CertainTeed roof repair in Orlando, here’s what happens, step by step.
- 1
You call (850) 757-3564 and talk to a person. Not a voicemail, not a call-back form. We ask what you’re seeing, where the stain is, and when it started. That tells us a lot before we ever put a ladder up.
- 2
We diagnose the actual source. Water travels. A stain on the living room ceiling might be a valley flashing failure forty feet away. We inspect the roof, the attic, and the decking from underneath when possible. On a CertainTeed roof, we check the specific failure points we listed above.
- 3
We write the price down. Before any work starts, you get a written quote. Not an estimate with a fuzzy range, not a verbal promise. A number. If it changes, it changes before we start, not after.
- 4
We decide on parts together. For CertainTeed repairs, we use CertainTeed shingles wherever the color and style are still available. If a line has been discontinued, we’ll show you the closest-aftermarket match and explain the difference in writing. The choice is always yours.
- 5
We make the repair. Our technicians arrive in a marked uniform with a photo ID badge, and their name and photo are sent to you before they show up. The repair itself is done to manufacturer spec, including correct fasteners, sealant, and underlayment where needed.
- 6
We test and guarantee it. We run water over the repair area when we can, or inspect from the attic after the next rain if the weather cooperates. Every repair includes our 365-Day Done Right Promise in writing. If the repair fails within a year, we return and make it right at no cost.

Why Orlando Homeowners Call Mercer Roofing Co Orlando for CertainTeed Work
People in Orlando call us because we solve the problem most roofers ignore: you don’t actually know who’s coming to your house. Every Mercer Roofing technician is background-checked, identity-verified, and badged under the Threshold Verified standard. Before they arrive, you get their name and photo. When they knock, they’re in a clean uniform with a photo ID you can check at the door. That matters if you’re home alone, if you’ve got kids in the house, or if you’ve been burned by a driveway contractor before.
We’ve been doing this since 2000, and we’re part of the Threshold Group family of home-service companies, every location independently owned and operated. When a CertainTeed repair fails because of a discontinued shingle or an oddball flashing detail, we can also pull from our experience with GAF and Owens Corning products to find a compatible fix. And every repair, on every job, is covered in writing by our 365-Day Done Right Promise: if it’s not done right, we make it right within a year. That includes spelling out the guarantee before work starts, not after. Written price, written guarantee, techs you know by name. That’s how we work.
FAQs
No, repairing your CertainTeed roof with an independent contractor does not void the manufacturer’s material warranty, as long as the repair is done correctly and uses compatible materials. The certainteed warranty covers manufacturing defects in the shingles themselves, not installation workmanship. We’re careful to use CertainTeed shingles where they’re still produced and to install them according to the manufacturer’s published specs. If you ever need to file a certainteed warranty claim, we’ll help you understand what’s covered and what isn’t. Call (850) 757-3564 if you’re not sure where your warranty stands.
It depends on the line and how old it is. CertainTeed Landmark colors like Weathered Wood, Moire Black, and Georgetown Gray are usually still in production and easy to match. Older three-tab lines like XT 25 are often discontinued, but we can usually find a close aftermarket match or pull shingles from an inconspicuous area of your roof for the repair, then patch that area with the closest available match. We’ll show you samples before we install anything. Call (850) 757-3564 and tell us what your roof looks like; we’ll let you know what’s possible.
Most leak repairs in the Orlando area can be scheduled within a few days, and the repair itself usually takes two to four hours once we’re on site. If a storm just came through and water is actively entering your home, call (850) 757-3564 and we’ll work with you to get a tarp up or get someone out faster. A live person answers the phone, so you’ll know the timeline before you hang up.
Repair makes sense when the damage is localized (a few shingles, one flashing point, one vent boot) and the rest of the roof still has solid life left. In Orlando, a well-installed CertainTeed architectural shingle roof can last 20 to 25 years, so if yours is ten years old and has a single valley leak, repair is almost always the right call. If the roof is past twenty years old with widespread granule loss, curling shingles, or multiple leaks in different locations, we’ll tell you that too. We don’t sell replacements you don’t need. Call (850) 757-3564 for an honest assessment of what you’re working with.
OEM means actual CertainTeed shingles and accessories, made in CertainTeed plants and matched by color code. Aftermarket means shingles or flashing made by another manufacturer that look similar but aren’t identical. For shingle replacement, we always try OEM first because the color and profile match is exact. For things like vent boots, pipe collars, and some flashing materials, the aftermarket options are often just as good and sometimes better, because they’re made by companies that specialize in those components. We’ll always tell you which one we’re using and why, in writing, before we start. Call (850) 757-3564 and we’ll walk you through it for your specific roof.
