CertainTeed Roof Installation in Dallas: What to Know First
CertainTeed roof installation in Dallas typically runs $9,800 to $18,400 for a full tear-off and replacement on a 2,000-square-foot home, depending on which CertainTeed shingle line you choose and the condition of your decking underneath. Most jobs take two to four days from tear-off to final cleanup. As an independent CertainTeed service provider, we give you a written line-item price before a single nail gets driven, and we never start work without it.
If you own a CertainTeed roof that’s nearing the end of its life, or you’re comparing CertainTeed against other brands for a new installation, this page tells you what actually happens on a CertainTeed job in Dallas, what things cost, and where roofs in this market tend to fail first. Call (432) 302-5605 with any questions, or to schedule a free estimate.
How CertainTeed Products Fail – and How We Fix Them
- Landmark and Landmark Pro granule loss (the telltale “balding” shingle). Dallas summers push roof surface temps past 150°F, and after about 12 to 15 years, the ceramic granules on CertainTeed’s standard architectural lines start shedding into gutters. You’ll see dark patches on the shingle face and a buildup of granules at downspouts. The fix isn’t re-granulating, which no reputable roofer does; it’s a localized replacement if the damage is isolated, or a full reroof if granule loss is widespread. We’ll tell you which one honestly, because a 14-year-old Landmark roof with 40% granule loss isn’t worth patching.
- Presidential Shake and XT 30 curling from attic heat. CertainTeed’s premium laminated lines are thicker and more rigid than standard architectural shingles. In Dallas’s 100°F-plus summers, if attic ventilation wasn’t installed correctly at the time of the original roof, those thick shingles curl at the edges and crack along the nail line. We check venting before we quote the job. A roof replacement on a house with one puny ridge vent and no soffit intake will fail the same way in five years, regardless of what shingle you put on.
- Integrity and CT 20 flashing failures at transitions. Most CertainTeed roof leaks we see in older Plano and Richardson homes aren’t shingle failures at all. They’re flashing failures where the roof meets a chimney, a wall, or a valley. The original installer used thin, low-grade step flashing or skipped the kickout flashing entirely. On our CertainTeed installations, we use 24-gauge galvanized flashing, and we replace every piece of flashing on a teardown rather than trying to reuse it.
- WinterGuard and DiamondDeck underlayment breakdown at eaves and low slopes. CertainTeed makes excellent synthetic underlayments, but in Dallas, the problem is installer error: we regularly see roofers skimp on underlayment at the eaves, on dormers, and on low-pitch sections. Those are exactly the spots where ice damming and wind-driven rain hit first. Our standard is two courses of underlayment at the eave line and ice-and-water membrane on any pitch lower than 3:12, regardless of what the building code minimum says.
- Starter strip and ridge cap neglect (the leak you don’t see until it’s too late). CertainTeed warranties require their starter shingles and ridge caps to be installed with the field shingles. If a contractor skips the starter strip at the eave, or uses generic caps instead of the matching CertainTeed product, the manufacturer can deny a warranty claim later. We inspect every roof for starter and cap issues before quoting, and we use CertainTeed-branded accessories on every CertainTeed job.

Our CertainTeed Roof Installation Process
Here’s what a full CertainTeed roof installation with us looks like, from first call to final sweep.
- 1
Call and schedule the free estimate. A live person answers, not a voicemail, and we’ll set up a time that works for you. Before our tech arrives, we’ll send you their name and photo so you know who to expect at the door.
- 2
The inspection. Grant Whitlock or one of us walks the roof and the attic, takes photos, and checks decking, flashing, ventilation, and the current shingle condition. We look for the specific CertainTeed failure modes we described above, and we show you what we find.
- 3
The written quote. You get a line-item price in writing. No change orders, no “we’ll see what we find” pricing. The number we give you is the number you pay, unless we both agree to something different in writing before the work changes.
- 4
Tear-off and prep. We strip the old roof to the decking, inspect for rot and soft spots, replace any bad decking, and install new underlayment, drip edge, and starter shingles per CertainTeed’s published installation requirements.
- 5
Installation and cleanup. We install the field shingles, ridge caps, and all flashing in line with the manufacturer’s specs and Dallas code. We run a magnet sweep for nails daily and do a final pass before we leave.
- 6
Written guarantee and the 365-Day Done Right Promise. You get the warranty in writing before we leave. If anything isn’t right within a year, we make it right.

What moves the price: roof pitch (steep roofs cost more), access (tight Dallas lots with fences and landscaping), decking condition, and whether you need any structural work once we strip to the deck. That’s why we quote after inspection, not before. Call (432) 302-5605 for a free estimate with a written, line-item price.
Why Dallas Homeowners Call Mercer Roofing Co Dallas for CertainTeed Work
A roof shouldn’t be something you worry about. Let’s make sure yours isn’t.
Here’s the thing most roofing companies in Dallas won’t say out loud: the shingle matters less than the people installing it. A CertainTeed roof installed wrong will fail years before a cheap roof installed right. That’s why we put our process in front of you, not just our brand pitch.
Every tech we send to your door is background-checked, identity-verified, and in a clean, marked uniform with a photo ID badge. You get their name and photo before they arrive, and they present that badge at the door. That’s the Threshold Verified standard, and we’ve been part of the Threshold Group family since 2000.
We install CertainTeed because it’s a good product, but we also work with GAF and Owens Corning for homeowners who need other options, and we’re honest about which one actually suits your roof. Every job gets the 365-Day Done Right Promise and a written guarantee on every repair. If a repair fails, we come back for a free second visit.
FAQs
No. CertainTeed’s shingle warranty covers the shingles themselves, not the installation, and it applies regardless of which licensed contractor installs them. What matters for a warranty claim is that the installation follows CertainTeed’s published specs. We install to those specs and document the whole job with photos, so if you ever need to make a claim, you have the evidence the manufacturer requires. Call (432) 302-5605 and we’ll walk you through what your specific CertainTeed warranty covers.
Two to four days for most full tear-offs, depending on the size and pitch of your roof and whether we find decking damage once the old shingles come off. Steep roofs on two-story Dallas homes, like a lot of the houses in Lakewood and Preston Hollow, can run four to five days. We’ll give you a schedule in writing with your quote.
If your CertainTeed roof is more than 15 years old, shows granule loss across more than a third of the surface, or has leaks in multiple spots, replacement usually beats repeated repairs. If the decking under the shingles is soft or rotted, that’s another sign. But the honest answer requires an inspection. We’ll tell you straight what you need and what you don’t. Estimates are free, and the price is in writing before we start.
No. The price we give you in writing is the price you pay, unless we find hidden damage that changes the scope and you agree to the new number in writing before we proceed. We don’t do surprise invoices.
Yes. Dallas requires permits for reroofing, and we pull them on every job. We’re also familiar with the specific code requirements that trip up roofers who mostly work in the suburbs, like the City of Dallas’s rules on ice-and-water shield and wind load ratings. Permits and inspections are included in our quote, never an add-on.
