How CertainTeed Products Fail – and How We Fix Them

• Landmark shingle granule loss after hailstorms. CertainTeed Landmark is the most common architectural shingle we see in Dallas neighborhoods like Lakewood, Richardson, and Plano. After a North Texas hailstorm, these shingles lose granules in a distinctive pattern: the asphalt underneath is exposed but not cracked. That exposed asphalt bakes in the summer sun and the shingle fails within two or three years. We document the granule loss, check the decking below, and either patch the affected area or recommend a full replacement depending on how widespread the damage is. Hail damage like this is why we keep detailed photo records on every CertainTeed job.
• Presidential Shake TL curling at the eaves. CertainTeed’s Presidential Shake TL is a heavier, thicker shingle meant to mimic wood shake. In Dallas, the problem isn’t usually the shingle itself – it’s what’s underneath it. Homes where the original installer skipped proper attic ventilation see these shingles curl at the edges within eight to ten years because trapped heat cooks the underside. We fix the ventilation first, then replace the curled shingles. If you replace them without fixing the airflow, you’ll be replacing them again in two years. Travis Oakley checks the attic on every Presidential Shake job before touching a single shingle.
• Flashing failures at roof-to-wall transitions. CertainTeed shingles can look perfect while the real leak is coming from step flashing that was never installed correctly where the roof meets a brick wall or chimney. This is common on older Dallas homes in East Dallas and Oak Cliff where original flashing was nailed too high or too low. Water gets behind the flashing, runs down the wall, and stains the ceiling. We pull the relevant shingles, install proper step flashing, and reseal. This is a $400 to $900 fix that a lot of roofers miss because they never look past the shingles.
• NorthGate and XT 25 membrane issues on flat roofs. CertainTeed’s NorthGate line and the older XT 25 are modified bitumen and roll roofing products we see on flat and low-slope roofs around the Stemmons corridor and warehouse districts. The weak point is almost always at the seams – Dallas heat expands and contracts the material until the lap seams crack and let water in. We strip the failed seam, apply new adhesive and membrane, and seal it with a cold-applied topcoat. On newer flat installations, we also check the drip edge, because that’s where water backs up when Dallas gets a hard downpour.
• Worn sealant strips on Landmark Pro and XT 30 IR shingles. The sealant strip on CertainTeed shingles is what keeps them locked down in a windstorm, and it does degrade over time in Dallas heat. When the sealant fails, shingles flap in the wind and eventually tear off. The telltale sign is shingles on the ground after a storm, or shingles you can lift with your hand from the roof edge. We reseal where possible, replace where the shingle is damaged, and always check the drip edge and starter course while we’re up there. Ignoring a few flapping shingles now is how you end up with decking rot later.

Our CertainTeed Roofing Company Process

1. 1
   We answer the phone. You call (903) 499-4441, a live person answers, and we schedule a time. No voicemail, no callback queue. The technician shows up inside the promised window, in uniform, with a name you already know.
2. 2
   We inspect the whole roof, not just the leak. On a CertainTeed job, we’re looking at the shingles or membrane, the flashing, the drip edge, the decking, and the ventilation. We take photos and document everything.
3. 3
   We put the price on paper before any work starts. You get a written line-item quote. The price does not move at the door. If we find something unexpected during the repair, we stop, call you, and get your approval before touching it. No change orders appended to the final bill.
4. 4
   We make the repair with the right materials. On CertainTeed work, we use manufacturer-spec parts where warranty or mechanical integrity depends on it, and quality aftermarket components where they perform just as well at a better price. We explain the difference in plain English so you decide with both eyes open.
5. 5
   We test before we leave. On every repair, we water-test the affected area and confirm the fix in writing. You’ll see the work, you’ll see what we did, and you’ll get exactly what the quote said.
6. 6
   We stand behind it for a full year. This is the 365-Day Done Right Promise. If that repair fails within one year, we come back and fix it at no charge. In writing, no fine print.

What CertainTeed Roofing Company Costs in Dallas

Dallas CertainTeed repairs are the kind of work where the range matters more than the number. Small fixes – a few missing shingles, a popped nail, a small flashing repair – run $350 to $650. Moderate work – resealing a section of shingles, replacing a patch of damaged decking, fixing multiple flashing points – lands between $650 and $1,400. Larger repairs or partial re-roofs go $1,500 to $3,500. Full CertainTeed roof replacement in Dallas typically runs $9,500 to $22,000 depending on square footage, pitch, decking condition, and whether you choose Landmark, Landmark Pro, or Presidential Shake. The main things that move the price: roof pitch (steep roofs cost more to work on), decking condition, and how many layers of old material need tearing off. Call (903) 499-4441 for a written line-item quote. Estimates are free.

Why Dallas Homeowners Call Brennan Roofing Co Dallas for CertainTeed Work

Crews that know CertainTeed products well don’t guess at the failure cause. We show up with the product lines and their failure patterns already in our heads – Landmark granule loss, Presidential Shake ventilation issues, NorthGate seam cracks. That means the diagnosis is faster and the fix is right the first time. We also don’t have to sell you on a full replacement when a $600 repair will hold. If the repair is the honest call, that’s the price we put on paper. And if you want to compare, our techs work with GAF and Owens Corning too, so if a product swap makes more sense for your roof and budget, we’ll tell you that plainly. Every technician on your roof is background-checked and in uniform. Every job is under the 365-Day Done Right Promise. We keep it simple: written price before any work starts, live person on the phone, and a one-year written guarantee. That’s The Garrison Standard, and we don’t work any other way.
