CertainTeed Roofing in Cibolo, TX | Mercer Roofing Co San Antonio
We provide independent CertainTeed roofing service across Cibolo, TX, through our Roofing Company in Cibolo. We’re not a CertainTeed-authorized dealer, and we don’t pretend to be. What we are is a local crew that works on CertainTeed roofs in Cibolo’s subdivisions every week, and we keep a running defect log tied to specific product lines so we know exactly how Landmark shingles, XT 25 tabs, and Flintlastic membranes fail under Cibolo’s hail and heat. If you need shingle replacement, vent boot repair, decking replacement, or flashing work on a CertainTeed roof, call Mercer Roofing Co San Antonio at (254) 276-4369 and we’ll give you a written price before any work starts.
Why Cibolo Residents Choose Us for CertainTeed Service
CertainTeed roofs in Cibolo tend to fail in patterns. Grant Whitlock, our owner, learned the trade through the construction technology program at Los Angeles Trade-Technical College, and he’s spent years teaching our crews to look for those patterns instead of guessing. When a Landmark shingle loses granules after a hailstorm, we already have notes on whether it’s an installation problem, a sealant failure, or something systemic with that product line. That’s the advantage of a crew that works the same neighborhoods week after week: we know what Cibolo’s climate does to CertainTeed materials.
We default to CertainTeed OEM shingles and accessories for warranty documentation and color match. For flashing, vent boots, and underlayment, we specify equal-or-better aftermarket parts that suit Cibolo’s hail and heat profile. The truth is a seam failure under a vent boot is rarely shingle-related, so we replace the boot and surrounding shingles only when the granule loss is structural. Every technician who arrives at your Cibolo door is background-checked, identity-verified, and badged with a photo ID. Their name and photo are sent to you before they arrive. That’s the Threshold Standard, and it’s non-negotiable on every job we run. We also carry full CertainTeed sales & service expertise across our whole operating area, but Cibolo is where we’ve built the deepest track record with these roofs.

Common CertainTeed Roofing Problems We Solve in Cibolo
- Landmark shingles losing granules prematurely. Cibolo’s 100°F-plus summers bake the asphalt layer, and granule loss accelerates fast once that process starts. Homeowners see granules piling up in gutters and dark patches spreading across south-facing slopes. We document the damage with date-stamped photos, then determine whether it’s sealant failure, hail impact, or a systemic granule-loss problem specific to that roof’s install year.
- Sealant bond failure on XT 25 3-tab shingles after spring hail. Hail breaks the bond between tab and sealant strip, and the first thunderstorm after that leaves shingles flapping. We see this pattern most on 2000s-era Cibolo homes, and the fix often means re-sealing or replacing the affected tabs before water gets underneath.
- Flintlastic SA pulling away at seams on low-slope porches. Repeated thermal cycling in Cibolo’s flash-flood-prone corridor makes the self-adhered membrane expand and contract until seams open. Leaks start before the membrane’s rated life. We inspect the seams first, then decide whether to reseal or replace the membrane section.
- Presidential Shake flexing and cracking at overlap points. These dimensional shingles need rigid decking. Many Cibolo homes from the 2000s were built with 7/16-inch decking, and the flex at overlap points causes cracks. We check decking condition before reinstalling any Presidential Shake.
- Vent boot and flashing failures that get blamed on shingles. A leak around a vent pipe usually has nothing to do with the shingle above it. It’s the boot seam. We replace the boot with a hail-rated aftermarket unit and only touch surrounding shingles if the granule loss is structural. This saves Cibolo homeowners from paying for shingle replacement they don’t need.
CertainTeed Service in Cibolo: What Local Conditions Mean for Your Equipment
Cibolo’s Deer Creek and Turning Stone neighborhoods have an unusually high concentration of CertainTeed Landmark roofs installed during the 2013-2016 building boom. After every major hail event, our techs find the same pattern in those subdivisions: edge shingles near valleys missing sealant while ridge caps stay intact. That’s not random. Hail hits the rakes and valleys first, and the original sealant on those Landmark roofs has been cooking in Texas sun for eight to twelve years. We pre-stage extra Landmark bundles and valley flashing before storm season specifically because we know Deer Creek and Turning Stone will need them. A crew that doesn’t work Cibolo every week wouldn’t know to do that. It’s what we mean when we say local knowledge changes the work.
CertainTeed Models & Products We Service in Cibolo
We service the CertainTeed lines most common on Cibolo roofs: Landmark architectural shingles, XT 25 3-tab shingles, Presidential Shake, and Flintlastic SA low-slope membrane. We stock Landmark bundles in the colors seen most often across Cibolo’s newer subdivisions, which means faster turnaround on repairs. For flashing, vent boots, ridge vents, and underlayment, we carry aftermarket components rated for Texas hail and heat. Our warranty documentation uses CertainTeed OEM shingles where it matters, so your manufacturer paperwork stays clean. For Cibolo service area coverage, we run jobs weekly across the city’s subdivisions and surrounding streets.

FAQs – CertainTeed Roofing in Cibolo
No. CertainTeed’s standard limited warranty covers manufacturing defects, not hail, wind, or storm damage. Hail damage in Cibolo is typically an insurance claim, not a warranty claim. We document pre-existing condition and storm damage with date-stamped photos, which gives you exactly what your insurer needs. Call (254) 276-4369 for an inspection and written documentation.
Cibolo’s prolonged 100°F-plus summers bake the asphalt and accelerate granule loss, especially on south-facing slopes. Add hail impacts that loosen the granule bond, and shingles that should last twenty-five years start showing dark patches at twelve. It’s not always a manufacturing defect. It’s the local climate working against the roof. The fix depends on how structural the loss is, and we’ll tell you straight before recommending replacement.
Usually, you replace only the damaged shingles plus any compromised flashing or decking through our Roof Repair in Cibolo. Full roof replacement is for widespread granule loss, structural decking failure, or when matching the existing color becomes impossible. We inspect first, document everything, and give you a written price for only what’s actually wrong. If a spot repair is the honest answer, that’s what we quote. Call (254) 276-4369 for a free assessment.
It’s almost never the shingles. The vent boot seam fails from thermal cycling, and water follows the pipe down. We replace the boot with a hail-rated aftermarket unit and only touch surrounding shingles if the granule loss is structural. This is the single most misdiagnosed leak on Cibolo roofs, so we always check the boot first.
Cibolo’s housing stock is newer and more uniform, mostly 2000s-era and later tract homes with steep asphalt shingle roofs on generous lots. That means longer ladder setups, more valleys to flash, and a higher concentration of CertainTeed Landmark roofs from specific build years. San Antonio has older, more varied housing. In Cibolo, we know the roof before we climb the ladder, because we’ve worked its neighborhoods since the building boom. For CertainTeed service in San Antonio or CertainTeed service in Schertz, that same process applies, adjusted to each city’s housing stock.
