CertainTeed Roofing in San Antonio, TX | Mercer Roofing Co San Antonio
We provide independent CertainTeed roofing service across San Antonio, from full Landmark architectural re-roofs to targeted flashing repair on older XT 30 composition roofs. The thing that makes our CertainTeed work here different is that we don’t just replace shingles – we understand how San Antonio’s hail patterns, summer heat cycling, and freeze-thaw January swings wear down specific CertainTeed product lines on specific slopes. You can reach us at (254) 276-4369 for a straight estimate.
Mercer Roofing Co San Antonio has been working on CertainTeed sales & service since before much of the city’s suburban housing stock needed its first full replacement. We’re independently owned and operated, part of the Threshold Group family founded in 2000. That means every technician who arrives at your door has been background-checked, wears a photo ID badge, and shows up in a clean uniform – and you’ll know their name and face before they ring the bell. No surprises at the door, no surprises on the invoice. San Antonio homeowners across our San Antonio service area tell us that’s exactly what they want after a hailstorm, when unfamiliar trucks start circling the neighborhood.
Why San Antonio Residents Choose Us for CertainTeed Service
CertainTeed roofs require a contractor who knows the difference between a color-matched Landmark shingle and whatever the supply house has on sale that week. Our crews work on CertainTeed roofs across San Antonio, from 1970s suburban compositions to newer architectural systems, and we keep a running catalog of how their product lines behave under hail, wind-driven rain, and thermal cycling in South Texas. As a San Antonio Roofing Company, we bring deep local knowledge to every project. Grant Whitlock, owner of Mercer Roofing Co San Antonio, learned the trade through the construction technology program at Los Angeles Trade-Technical College before spending decades on real roofs in real weather. He’s led projects across the Alamo Heights area, where older homes demand careful flashing work and a patient hand with existing trim.
When you call us about a CertainTeed roof, you get a live person on the phone – 24/7, not a voicemail. You get a written price before any work starts. And you get a written guarantee on every repair, good for 365 days. If the repair fails within that year, we come back at no charge. That’s our Done Right Promise, and it’s backed by the Threshold Verified standard every Mercer technician is held to.

Common CertainTeed Roofing Problems We Solve in San Antonio
- Hail-induced granule loss on Landmark shingles. South-facing slopes in San Antonio take the worst of spring supercell hail. Granules shear off at impact points, exposing the asphalt mat to UV, and within two summers those spots become bare patches that leak. We replace the affected shingles with OEM-matched Landmark stock, not patch-over.
- Wind damage at the 5-inch exposure on older XT 30 shingles. Repeated summer heat cycling plus monsoon humidity weakens the seal strips. When the next windstorm hits, entire tabs lift. We see this most often on homes built in the 1980s and 1990s across the city’s northern subdivisions.
- Valley and flashing failures on Presidential Shake roofs. The heavier laminated shingles create uneven wear at transition points, catching debris and water. San Antonio’s oak and pecan leaves clog those valleys fast. We pull and re-flash rather than caulk over a failing transition.
- Nail pops and decking rot from smooth-shank nails. January and February freeze-thaw swings make smooth-shank nails back out of plywood decking. By March, you’ve got popped shingles and soft spots around the nail heads. We replace rotted decking and re-nail with ring-shank fasteners.
- Vent boot and pipe flashing corrosion. San Antonio’s humidity plus the heat radiating off composition shingles corrodes standard metal vent boots in a decade. We swap them for higher-quality aftermarket flashings that outlast CertainTeed’s standard parts in this climate.
CertainTeed Service in San Antonio: What Local Conditions Mean for Your Equipment
Here’s something most homeowners don’t learn until they’re standing in a permit office: San Antonio does not require a re-roofing permit for simple shingle replacement, only for structural changes. That means after a hailstorm, we can schedule your CertainTeed repair and start pulling damaged shingles the same week – no waiting on city approvals. Compare that to neighboring Alamo Heights or Castle Hills, where local permitting rules are stricter and slower. If you live in San Antonio proper and your Landmark shingles took hail, you’re clear to start. This also means storm-chasing contractors can start just as fast, which is why verifying who’s on your roof matters. The city sees a wave of door-to-door roofing salesmen after every major hail event off Loop 1604. We tell homeowners to check for out-of-state plates and ask for a local permit record on structural work. A roof shouldn’t be something you worry about – that’s our job.
CertainTeed Models & Products We Service in San Antonio
We install and repair Landmark architectural shingles, XT 30 composition shingles, Presidential Shake luxury shingles, and Mountain Ridge slate-look shingles. For shingle color and profile matching, we source OEM CertainTeed components through local San Antonio suppliers. For underlayment and metal flashings, we often recommend higher-quality aftermarket materials that withstand hail and humidity better than CertainTeed’s standard parts. Our default on any CertainTeed roof in this climate is to replace the affected shingle or flashing rather than patch it, because repeated spot repairs usually cost more over five years than one full slope replacement done right.

AfterCertainTeed Service Pricing in San Antonio
Expect to pay roughly $350 to $600 for a typical CertainTeed shingle repair in San Antonio, including removal of damaged shingles, decking inspection, and color-matched replacement. Flashing repair runs $250 to $500 depending on whether we’re replacing a corroded vent boot or re-flashing a valley. Full slope replacement with Landmark architectural shingles starts around $4,500 and moves up depending on decking condition and roof pitch. What drives the cost: how many damaged shingles, whether decking has rot from nail pops, and whether we need to source a discontinued color. Every estimate is free and written – you’ll know the price before a single nail goes in. Call (254) 276-4369 for your exact number.

FAQs – CertainTeed Roofing in San Antonio
No – simple shingle replacement in San Antonio does not require a re-roofing permit. The city only requires permits for structural changes like decking replacement or rafter work. So your CertainTeed repair can start the same week a storm hits, without city approval delays. Call (254) 276-4369 and we’ll confirm what your specific job needs.
That’s granule loss from past hail impacts that went unrepaired. The exposed asphalt mat oxidizes under San Antonio’s UV, and the shingles shed more granules every year. If the bare spots are widespread, a full slope replacement makes more sense than patching. Call (254) 276-4369 for a free inspection and written estimate.
We can usually match XT 30 colors through local CertainTeed suppliers, though sun-bleached older roofs will always show some difference until the replacement shingles weather in. If your roof is more than 15 years old, we’ll be straight with you about whether a patch or a slope replacement makes more financial sense.
For manufacturing defects, CertainTeed handles warranty claims directly, but an independent contractor like Mercer Roofing Co San Antonio can document the failure, provide photos and measurements, and advise whether the issue is actually a defect or weather damage. Most San Antonio CertainTeed failures we see are storm-related, not manufacturing defects.
Ask for their local business license, check for out-of-state plates, and verify they carry liability insurance that covers roof work. Ask for a written price before any work starts – if they won’t put it on paper, walk away. Mercer Roofing Co San Antonio is part of the Threshold Group, founded in 2000, and every technician is background-checked and photo-badged. Call (254) 276-4369 and a live person answers.
