CertainTeed Roofing in Schertz, TX | Mercer Roofing Co San Antonio
CertainTeed roofing service in Schertz means working with a contractor who knows how these shingles hold up under I-35 corridor hail. Mercer Roofing Co San Antonio is an independent Schertz Roofing Company, not a manufacturer affiliate, and we’ve repaired and replaced hundreds of CertainTeed roofs across Schertz’s older subdivisions and new builds. What sets our work apart here is simple: we know which CertainTeed failure modes show up after a Schertz hailstorm, and we price the fix honestly before we start. Call (254) 276-4369 for a free estimate.
Why Schertz Residents Choose Us for CertainTeed Service
CertainTeed shingles are all over Schertz. Drive through Fairhaven or any of the 1980s-era neighborhoods off FM 3009 and you’ll spot Landmark Series roofs that have been through two or three declared hail events. Grant Whitlock, our owner, came up through Los Angeles Trade-Technical College’s construction technology program and has spent years on Texas roofs where the real education happens: stripping storm-damaged shingles and seeing exactly where they failed. We bring that to every CertainTeed job in Schertz.
We’re independent, which means we don’t have a brand rep telling us what to sell. We recommend what holds up on a Schertz roof. We use genuine CertainTeed shingles and accessories for replacements so wind and hail ratings stay intact, and for discontinued lines we source aftermarket alternatives that match color and profile. A roof shouldn’t be something you worry about – that’s our job.
Every technician who arrives at your Schertz home is background-checked and photo-badged under the Threshold Verified standard. We send you their name and photo before they show up. You’ll know who’s at your door before you open it.

Common CertainTeed Roofing Problems We Solve in Schertz
- Hail-induced granule loss on Landmark Series shingles. After a Schertz hailstorm, granules shear off the asphalt mat, leaving dark patches where the fiberglass begins to show. On older roofs still carrying 1990s-era CertainTeed shingles, this often means the shingle is compromised and water is next. We inspect every slope, not just the one facing the storm.
- Wind uplift and shingle blow-off along ridge lines. Schertz’s steep-slope homes catch south Texas wind hard at gable edges and ridges. CertainTeed shingles with aged adhesive strips lift, then tear. We re-secure or replace those shingles and check the ridge cap line thoroughly, because that’s where the water gets in after the shingle’s gone.
- Cracking and brittleness in XT 30 IR shingles. Repeated thermal cycling, with Schertz summers pushing roof temperatures past 140 degrees, bakes older XT 30 shingles brittle. Add a hail hit and they crack at nail lines. Leaks follow. We see this most on homes built between 1995 and 2005 that never got a full replacement after the first big storm.
- Failed adhesive strips causing wind-driven rain intrusion. Texas heat eventually kills the sealant on CertainTeed shingles’ overlap strips. When a Schertz thunderstorm drives rain sideways, water works under the shingle laps. Homeowners notice ceiling stains days later. We replace the affected shingles and re-seal the surrounding overlaps.
- Decking rot hidden under old CertainTeed roofs. Original roofs from the 1980s and 1990s in Schertz often have plywood decking that’s been damp for years. We replace rotted decking before laying new shingles, because new CertainTeed shingles can’t fix what’s rotting underneath them.
CertainTeed Service in Schertz: What Local Conditions Mean for Your Equipment
Schertz sits in a hail-prone corridor where insurance claim cycles drive roof replacements. That’s not true of every San Antonio suburb, and it changes how CertainTeed roofs age here. Many homes in neighborhoods like Fairhaven still carry original CertainTeed shingles from the mid-1990s. Those roofs have now absorbed two or three back-to-back hail seasons, each one knocking off more granules and bruising the shingle mats. We’ve found that a CertainTeed roof in Schertz that looks fine from the street often has bruising you can only feel by running your hand across the shingle, and that bruising is what insurance adjusters look for when approving a claim. The proactive move is an inspection before the next declared catastrophe, because once a storm is declared, every roofer in town gets busy and scheduling tightens up. We’d rather catch the damage now, document it, and get your claim filed through Schertz Roof Repair on your timeline, not the storm’s.
After a spring hailstorm, our crew replaced a Landmark Series roof on a Fairhaven home where half the shingles showed bruising and granule loss. We stripped the old shingles, replaced four sheets of water-damaged decking, and installed new Landmark architectural shingles with upgraded synthetic underlayment, finishing before the next front moved through. That’s the pace Schertz demands when hail season hits.
CertainTeed Models & Products We Service in Schertz
We service the CertainTeed lines most common on Schertz roofs. Landmark Series architectural shingles are the workhorse here, and we handle everything from single-shingle replacement to full tear-offs. XT 30 IR shingles, common on late-1990s homes, get inspected for hail bruising and thermal cracking. Landmark TL tri-laminate shingles show up on higher-end Schertz builds and need careful flashing work at valleys and sidewalls. Belmont IR shingles, a heavier architectural option, hold up well but still need storm inspection.
For repairs we use genuine CertainTeed shingles and accessories so the system’s wind and hail ratings stay valid. When a color’s been discontinued, we source aftermarket alternatives that match profile and blend with the existing roof. We stock common Landmark colors locally for faster turnaround on Schertz repairs. For broader services, see CertainTeed sales & service.

FAQs – CertainTeed Roofing in Schertz
If hail damage is limited to one slope, a repair usually makes sense, but if two or more slopes show bruising and granule loss, replacement is typically cheaper long-term. Our inspection documents every slope so you can decide with the full picture. Call (254) 276-4369 for a free inspection and written estimate.
Most Schertz homeowner policies cover hail damage to CertainTeed roofs when the damage meets the policy’s threshold, usually documented bruising or granule loss across a certain number of test squares. We help you file and meet your adjuster on-site. Call (254) 276-4369 and we’ll walk you through what your policy covers.
For current CertainTeed colors, yes, we source genuine shingles in your exact color. For discontinued colors, we use aftermarket alternatives that match profile and blend closely. We’ll show you samples before we start. Call (254) 276-4369 to schedule a color match.
Landmark architectural shingles typically last 22 to 28 years in Schertz, but hail can shorten that significantly. Homes in Fairhaven with 1990s originals are at or past that window now. A free inspection tells you where your roof stands. Call (254) 276-4369.
