How CertainTeed Products Fail – and How We Fix Them
CertainTeed makes a solid shingle, but every roof in Dallas eventually faces the same set of problems. Here’s what we see most often on CertainTeed roofs specifically, and how we address each one.
- Landmark shingle granule loss after hail. Dallas hail is notorious, and Landmark’s granule adhesion, while good, can surrender to golf-ball-size impact. You’ll notice bare asphalt patches on shingles or granules piling up in gutters. We inspect every slope, photograph the damage for your insurance file if needed, and replace impacted shingles with color-matched CertainTeed stock so the repair blends.
- Presidential Shake wind lift at the edges. The Presidential Shake’s thick, dimensional profile looks great, but its edges catch north Texas wind differently than flat shingles. Over time, sealant strips fail and shingles lift. We reseal lifted tabs using the correct adhesive and replace any shingles with cracked or torn corners before sealing. Most Dallas homeowners first notice this after a spring storm front moves through.
- Landmark Pro nail-line misplacement on older installs. We regularly find shingles installed by previous crews with nails driven above the nail line, which CertainTeed’s warranty doesn’t protect. The shingles slip over time, especially on south-facing Dallas slopes where attic heat weakens the adhesive. We assess the install pattern, explain what’s holding and what’s not, and give you a straight answer on whether repair or replacement is the smarter call.
- Flashing failures around Dallas chimneys and skylights. No shingle survives bad flashing. On CertainTeed roofs, we see step flashing pulling away from Dallas chimneys due to clay-brick expansion in our heat, and skylight flashing losing its seal after years of UV exposure. We replace flashing, re-seat the shingle courses around it, and use corrosion-resistant fasteners that hold up to Dallas humidity swings.
- Northgate and Landmark algae streaking on north-facing slopes. Dallas humidity and shade create ideal conditions for dark algae streaks. CertainTeed’s StreakFighter protection exists on some lines, but older Northgate and base Landmark shingles still streak. We treat algae growth with the proper cleaning agent and soft-wash methods that don’t void your shingle warranty, then recommend a treatment schedule for slopes that don’t see sun.

Our CertainTeed Roofing Company Process
Here’s what a typical CertainTeed repair or replacement looks like when you call us:
- 1
You call, a person answers. Not a voicemail. We take your details, ask what you’re seeing, and schedule a visit at a time that works for you.
- 2
We send you the technician’s name and photo before arrival. When our tech rings the bell, they’ll be badged and in a clean uniform. You’ll already know who’s at the door.
- 3
Full inspection, honest report. We get on the roof, inspect the CertainTeed shingles, underlayment, decking, flashing, and ventilation. Then we tell you what actually needs work and what doesn’t. Grant’s rule: never sell work a roof doesn’t need.
- 4
Written price before work starts. You get a line-item quote. The price doesn’t change once we’re on the job unless you ask for additional work and approve a new quote first.
- 5
The repair or replacement, done right. We use CertainTeed OEM parts where warranty compliance matters, and quality aftermarket components where the manufacturer doesn’t restrict it. We’ll tell you which is which.
- 6
Cleanup and written guarantee. We magnet-sweep for nails, haul debris, and leave your property the way we found it. Every repair gets a 365-day written guarantee.

FAQs
Repairs done by an independent CertainTeed roofing company in Dallas don’t void your shingle warranty, as long as the work follows proper installation practices. We’re careful to use CertainTeed OEM parts where warranty compliance requires it, and we document every repair with photos. The bigger risk to your warranty is the original installation, which is something we inspect and report on honestly.
We can typically schedule a Dallas CertainTeed inspection within a few days, and for active leaks we prioritize getting someone out quickly. A live person answers our phone 24/7, so if you’re seeing water or shingles in the yard, call (432) 302-5605 and we’ll get you on the schedule.
If your CertainTeed roof is under 10 years old and damage is limited to a few shingles or a flashing point, repair is usually the right call. If the roof is over 15 years old and you’re seeing granule loss across multiple slopes, curling edges, or recurring leaks, replacement starts making more financial sense. We’ll tell you which one we’d choose if it were our house, and we’ll quote both when it helps.
We use CertainTeed OEM parts whenever warranty compliance is a factor, like matching shingle stock or using the correct underlayment. For components like flashing, fasteners, and sealants, we use high-quality aftermarket parts that meet or exceed spec and hold up to Dallas weather. We’ll always tell you which is going on your roof and why.
No. The written quote you approve before work begins is the price you pay, unless you ask us to add work and sign off on a new quote. We don’t do surprise change orders, and every repair includes the 365-day written guarantee at no extra cost. Call (432) 302-5605 for a free estimate, and you’ll have a real number in writing before you decide anything.
