CertainTeed Shingle Repair: The San Antonio Owner’s Guide
We stock and install CertainTeed-compatible shingle repair materials across San Antonio, with most repairs running $280 to $650 installed depending on the shingle line and how many squares are involved. Same-day service is available when you call before noon, and our trucks carry Landmark, Landmark Pro, Landmark Premium, and NorthGate color-matched bundles plus starter strips and ridge caps. Most homeowners in San Antonio spot CertainTeed shingle trouble after a spring hailstorm or when they notice grit washing out of their gutters - sometimes it’s a single tab lifted by wind, sometimes it’s a whole slope where the sealant strip has cooked loose after years of 100-degree afternoons.
Which CertainTeed Models This Applies To
CertainTeed’s shingle lines each carry different weights, exposures, and sealant chemistry, and matching them wrong is where a repair starts looking like a patch job. We work with Landmark (the workhorse 3-tab and architectural lines), Landmark Pro and Premium (heavier laminate with dual-layer construction), NorthGate (SBS-modified asphalt for impact resistance), and the discontinued Presidential Shake and Grand Manor lines still found on homes in Alamo Heights and Terrell Hills.
To identify what you’ve got, check the underside of a loose shingle or the packaging if any was left in your garage. The CertainTeed label prints the product name, color code, and lot number - the lot matters because granule color shifts between production runs, and a repair with a mismatched lot will show from the street in San Antonio’s hard afternoon light. We keep current-color stock for the active lines and can source close-match discontinued bundles through our distributor when we’re dealing with older roofs in neighborhoods like Monte Vista or Beacon Hill.
We use OEM CertainTeed starter strips, ridge caps, and field shingles on every repair - no generic substitutions that void the remaining manufacturer’s warranty. For homeowners whose original CertainTeed warranty is already expired, we still recommend OEM because the granule adhesion and sealant activation temperature are spec’d to work together; mixing brands on the same slope is a common shortcut that costs more the second time.
Signs Your CertainTeed Shingle Repair Is Failing
- Curled or cupped shingle edges. The asphalt core has dried past the point where the sealant strip can hold. In San Antonio, we see this accelerate on south-facing slopes where attic ventilation is poor - the shingle bakes from both sides.
- Granule loss leaving bald black patches. Those granules are your UV shield. Once they’re gone, the fiberglass mat underneath degrades fast. We find this especially on CertainTeed repairs where a previous contractor used a non-OEM shingle with softer asphalt that sheds granules faster in Texas heat.
- Lifted tabs after wind under 60 mph. The self-seal adhesive has failed. CertainTeed’s sealant activates with solar heat, but if the shingle was installed in cool weather without hand-sealing or if debris blocked sun exposure, the bond never set properly.
- Cracks running through the shingle body, not just the surface. Thermal cycling in San Antonio - 40-degree winter nights to 105-degree August afternoons - eventually fatigues the fiberglass mat. This is structural failure, not cosmetic.
- Water stains on the ceiling directly below a valley or penetration. The shingle may look intact from the ground, but the waterproofing layer beneath has failed. We photo-document this during inspection because homeowners often dispute what they can’t see.
Replacement Cost & What’s Included
| Repair Scope | Typical Range (San Antonio) |
|---|---|
| Single shingle/tab replacement (wind lift, small hail) | $280 - $380 |
| Multiple shingle repair, same slope (up to 2 squares) | $450 - $650 |
| Ridge cap replacement (full ridge run) | $380 - $520 |
| Valley shingle repair with ice/water shield | $520 - $780 |
| Emergency tarp + scheduled repair bundle | $180 tarp + repair above |
What drives the range: shingle line (Landmark Premium runs heavier and costs more per bundle than base Landmark), roof pitch (steeper means more labor and safety setup), and whether we find decking damage once the failed shingles come off. Our estimate includes removal, disposal, matching shingles, underlayment patch if needed, and a photo report. The 90-Day Done Right Promise covers the workmanship - if it leaks or lifts, we come back. No paperwork, no arguing.
We also honor our standing offers: $50 off any repair over $250, and a permanent 5% senior and veteran discount. The price we quote is the price you pay.
DIY or Call Us?
There’s a difference between what you can safely check and what you should safely do. Walking a roof in San Antonio summer heat is its own hazard - the shingles are soft, the slope is unforgiving, and a fall from a single-story eave can change your life. If you’re determined to look, check your gutters for granule buildup, scan from the ground with binoculars for lifted tabs, and check your attic for water stains on the underside of the decking. That’s where your inspection should stop.
Removing and replacing a shingle seems straightforward until you’re dealing with a brittle shingle that tears instead of releasing, nails that back out into the course below, or a sealant strip that won’t re-engage without proper heat and pressure. We’ve been called to fix homeowner repairs in Stone Oak and Helotes where the patch lifted in the first wind because the replacement shingle was slid in wrong and the nails missed the decking entirely. A roof either holds or it doesn’t. We build ones that hold.

FAQs
Landmark architectural shingles typically perform 18 to 25 years in San Antonio’s climate, though we’ve seen premature failure at 12 years on roofs with poor attic ventilation or where the original install skipped starter strips. The SBS-modified NorthGate line tends to stretch toward 30 years because the rubberized asphalt handles thermal cycling better. Call (833) 756-5022 and we’ll inspect yours for free - no obligation, no sales pitch.
A cracked or torn shingle cannot be reliably repaired; sealants and patches fail within one to two Texas summers because they don’t flex with the shingle body. The proper fix is removal and replacement with a matching shingle. We carry the tools and stock to do this in a single visit for most active CertainTeed lines.
Most single-area repairs are completed in two to four hours, including setup, removal, installation, and cleanup. We photo-document before and after so you see what was done without climbing up yourself. Same-day scheduling is available when you call before noon - (833) 756-5022.
We carry Landmark, Landmark Pro, Landmark Premium, and NorthGate in the most common San Antonio colorways: weathered wood, driftwood, charcoal black, and burnt sienna. Less common colors or discontinued lines require a morning pull from our distributor, which we coordinate before we arrive so there’s no wasted trip. If we don’t have it, we don’t charge you for the return visit.
