How CertainTeed Products Fail – and How We Fix Them

CertainTeed makes a solid product. But Jacksonville weather is hard on every roof, and CertainTeed lines have failure patterns we see over and over. Here’s what shows up on houses across Arlington, Mandarin, and San Marco.

• XT 25 and Landmark shingle blow-offs after summer storms. These 3-tab and architectural lines use a sealant strip that bonds shingles together. Over years of Duval County sun, that strip bakes hard and loses grip. When a strong afternoon storm rolls through, we get calls about shingles in the yard. The fix is usually a same-day replacement of the affected shingles, and honestly, often a conversation about whether the roof is near the end of its service life.
• Landmark Pro lifting at the edges on south-facing slopes. The south side of your roof takes direct sun for hours. We see the edges of CertainTeed shingles start to curl upward, which lets wind get underneath. We replace the curled shingles and check the drip edge. If the original install skipped a proper drip edge, that’s the root cause, and we’ll put that on your written quote in plain English.
• Flashing failures around vent pipes and chimneys. This isn’t unique to CertainTeed, but we see it most on roofs where the original flashing was a thinner aftermarket piece rather than CertainTeed’s own accessory line. Northeast Florida humidity rusts thin metal. We pull the old flashing, install new corrosion-resistant flashing, and seal it properly. If the boot around a plumbing vent is cracked, that’s a $250 to $400 repair most of the time.
• Granule loss on older Landmark roofs near the coast. Jacksonville’s salt air, especially east of the Intracoastal, accelerates granule loss. You’ll notice it as bare, darker patches on the shingles or granules collecting in the gutters. Granule loss in the first few years is unusual. After fifteen years, it’s a sign the roof is aging out. We’ll tell you which one you have.
• Valleys leaking on Presque Isle and other architectural runs. The valley is where two roof planes meet, and it moves water faster than any other spot on the roof. If the original install used cut shingles in the valley instead of a woven or metal valley, leaks show up within a decade. We repair the valley by removing the damaged shingles, installing proper valley flashing or re-weaving as needed, and testing the water flow before we walk off.

Our CertainTeed Roof Repair Process

Every repair job follows the same steps, whether we’re patching a flat membrane near Regency Square or replacing shingles on a two-story in Mandarin.

1. 1
   You call and talk to a person. No voicemail. We ask what you’re seeing, when it started, and what type of roof you have. Then we schedule a visit inside a window we actually keep.
2. 2
   We inspect the roof and the attic. A leak on the ceiling doesn’t always start directly above that spot. Water travels. Our technician checks the roof surface, flashing, and the attic underside to find the true source.
3. 3
   We explain what we found in plain English. You’ll hear the real trade words, like flashing, underlayment, and decking, but you’ll also get a plain explanation of each one and why it matters.
4. 4
   You get a written price before any work starts. The quote lists parts and labor in dollars. If we recommend a CertainTeed OEM part versus a quality aftermarket equivalent, we tell you the cost difference and our reasoning. The price on that paper is the price you pay. No door-to-door adjustments.
5. 5
   We do the repair. Background-checked, uniformed technicians handle the work. We use materials matched to your existing CertainTeed line where possible, including shingle color matching for Landmark and XT runs.
6. 6
   We test, we clean up, and we guarantee it. Water test where possible. Magnetic sweep for stray nails. Blow-off the roof deck. You get the 365-Day Done Right Promise in writing before we leave.
