CertainTeed Roof Inspection in Dallas: What to Know First
An independent CertainTeed roof inspection in Dallas typically takes 45 to 90 minutes on site, with a written report and photos delivered the same day. We charge a flat inspection fee in the $150 to $350 range depending on roof size and access, and that fee is credited toward any repair we do. This page is for owners of CertainTeed shingles, also known as CertainTeed products, who need to know what state their roof is in, whether the manufacturer’s warranty still applies, and what it will cost to fix whatever we find. Call (903) 499-4441 to book.
How CertainTeed Products Fail, and How We Catch It
CertainTeed has several shingle lines that show up regularly on Dallas roofs: Landmark, Landmark Pro, XT 25, Presidential Shake, and Highland Slate. Each fails a little differently. Travis Oakley has looked at thousands of them across the metro since bringing his crew to the Dallas market. Here is what we look for, and what we do about it.
- Landmark sealant tab blow-off after micro-hail. Landmark is CertainTeed’s workhorse architectural shingle, and the sealant strip can lose its grip after repeated small-impact hail, the kind Dallas sees every spring. The tabs lift slightly, then a good wind peels them back. We check seal integrity on every tab, not just the obvious missing ones. Fix is hand-sealing with an OEM-compatible adhesive or tab replacement when needed.
- XT 25 brittleness at the nail line. The XT 25 is an older 3-tab line still on plenty of 2000s-era Dallas homes. Its organic mat gets brittle with age, and the nail line cracks first. We see this on south-facing slopes most. If we find nail-line tears across more than 20 percent of the field, the honest answer is replacement, not patching.
- Presidential Shake trapped moisture under the keyway. CertainTeed’s luxury shake line has deep shadow lines that look great but hold water longer after a downpour. In Dallas’s humid spring and fall cycles, that trapped moisture accelerates granule loss at the keyway edges. We check those channels first on any Presidential Shake roof.
- Highland Slate surface cracking on steep slopes. Highland Slate is a heavier laminated shingle. Steep Dallas roofs, like the ones in Lakewood and Kessler Park, put more flex stress on the material. We look for surface cracks radiating from the nail heads. Small cracks get sealed; wide ones mean panel replacement.
- Flashing and valley failure around chimneys and dormers, regardless of shingle line. This one crosses every CertainTeed series. Dallas’s wide temperature swings expand and contract metal flashing, breaking the sealant bond at transitions. We spend as much time on the flashing as on the shingle field, because that’s where water actually gets in. We replace step flashing, counter-flashing, and valley metal when the seal is gone.

Our CertainTeed Roof Inspection Process
Here is how a Brennan Roofing Co Dallas CertainTeed inspection works, from the first call to the final photo.
- 1
You call (903) 499-4441. A live person answers, no voicemail. We book a two-hour arrival window, not an all-day wait.
- 2
Our background-checked, uniformed technician arrives. They walk the property with you, if you want, to hear what you have noticed before they get on the roof.
- 3
Full roof walk. We inspect shingle condition, sealant strips, flashing, drip edge, decking, underlayment, ridge vents, and penetrations. Photos are taken on every trouble spot.
- 4
Attic check. We look at the decking from underneath, check for moisture staining around nails and rafter ends, and verify ventilation is moving air, not just sitting there.
- 5
Written report with line-item pricing. You get the written report same day, with photos and a written price for every repair we recommend. That price goes on paper before any work starts and does not change at the door.
- 6
Repair, if you approve. We use CertainTeed OEM parts when the warranty matters, and quality aftermarket sealants and metals when they don’t. Every repair is backd by the 365-Day Done Right Promise, in writing, for one full year.

FAQs
No. An inspection by an independent contractor cannot void a CertainTeed warranty. We are not affiliated with or authorized by CertainTeed; we are an independent CertainTeed service provider. What voids a warranty is unapproved repair work, removing identification labels, or installing aftermarket parts in a way that contradicts the warranty terms. We use OEM-compatible parts and document everything so your warranty position stays clean. Call (903) 499-4441 with questions.
A CertainTeed roof inspection in Dallas costs $150 to $350 at Brennan Roofing Co Dallas, and that fee is credited toward any repair you approve. You get the report the same day. Call (903) 499-4441 to schedule.
Yes, when it makes sense. Aftermarket sealants, nails, and flashing metal are fine for most repairs and cost less. When the repair touches a warranty-covered component on a newer CertainTeed roof, we recommend OEM parts. The decision goes in your written quote, with the price difference stated before any work starts. Call (903) 499-4441 for a straight answer on your specific roof.
Inspections are usually done same day or next day. Repairs, once you approve the quote, run from a few hours for a tab re-seal to a full day for a valley replacement. We never start a repair without the written price in your hand. Call (903) 499-4441 to get on the schedule.
Repair if the damage is isolated and the rest of the field is sound. Replace if you have widespread tab seal failure, nail-line cracking across twenty percent or more of the roof, or an XT 25 line past its useful life. We will tell you the truth, in writing, with prices for both paths. Call (903) 499-4441 for a free estimate and an honest read.
