Owens Corning Roof Installation in San Antonio: What to Know First
Owens Corning roof installation in San Antonio typically runs $9,800 to $18,500 for a full tear-off and replacement on a standard single-family home, with most jobs completed in 2 to 4 days once materials are on site. We’re an independent Owens Corning service provider, which means we install the full line of Owens Corning shingles but we aren’t beholden to any manufacturer’s sales quotas or scripted upsells. That changes how pricing works: you get a written number before the first shingle comes off, and that number is the number on the final invoice.
This page is for San Antonio homeowners who already know they want Owens Corning on their roof or who are deciding between Owens Corning, GAF, and CertainTeed. If you want someone to walk the roof with you and explain the difference in plain English, call (361) 209-8857 and ask for a free estimate. We’ll send a real person, not a sales script.
Key Takeaways:
- Full Owens Corning roof installation in San Antonio runs roughly $9,800 to $18,500 depending on roof size, pitch, and shingle line
- We install Duration, Duration FLEX, Oakridge, and TruDefinition lines with manufacturer-backed warranties
- Every quote is written, line-item, and fixed before work starts
- The 365-Day Done Right Promise covers every installation for a full year in writing
How Owens Corning Products Fail – and How We Fix Them
Owens Corning makes a solid shingle. But every roof system fails eventually, and the failure patterns on Owens Corning roofs in San Antonio tend to follow a few predictable tracks. Here’s what we see in the field.
- Duration Series granule loss after hailstorms. Duration shingles hold their granules well under normal sun, but San Antonio hail doesn’t care about brand reputation. We regularly see Duration roofs in Stone Oak and Alamo Heights with bare asphalt patches after a 1.5-inch-plus hailstorm. Granule loss exposes the asphalt mat to UV, which shortens the roof’s life fast. Our fix: a full documented inspection with photos of every slope, then a written repair or replacement scope. No guesswork.
- Oakridge nail-strip tearing in high wind. The Oakridge line uses a standard nail strip, and on San Antonio’s older pier-and-beam houses where the decking flexes, we’ve seen shingles tear at the nail line during the spring wind season. The shingle didn’t fail. The fastening schedule did, or the decking moved. We correct the underlying issue first: new decking if it’s compromised, then re-nailing to code with ring-shank nails and re-installing the shingle course correctly.
- TruDefinition Duration FLEX sealant activation delay. Duration FLEX uses a proprietary sealant that needs warmth and time to fully bond. In San Antonio winters, when nights drop into the 30s right after an installation, that sealant can take longer to activate. If a shingle gets walked on before the seal cures, it can slide. We schedule FLEX installs with this in mind and we tell the homeowner not to let anyone on the roof for the first week in cold weather. It’s a small thing, but it prevents warranty claims.
- VentSure ridge vent separation on older installs. We find plenty of Owens Corning roofs in San Antonio where the original installer used the shingles but cheaped out on the ridge vent, or installed VentSure incorrectly with under-driven nails. The result is a ridge vent that lifts in wind, letting rain into the attic. We repair or replace the vent and re-secure it so the exhaust actually works. A roof is a system. The shingle brand is only one part.
- Flashing failures around San Antonio chimneys, not shingle failures. This one matters. On most Owens Corning roofs we replace in older San Antonio neighborhoods like Monticello Park or Jefferson, the shingles are still fine but the flashing is shot: the metal strips around chimneys, vents, and skylights. We use corrosion-resistant flashing and proper step-flashing technique on every Owens Corning install, because that’s where water actually gets in. It’s the most common leak source on any brand roof, and it’s the first thing we check.

Our Owens Corning Roof Installation Process
Here’s how a full Owens Corning installation runs when you hire us. No surprises, no change orders at the door.
- 1
Call and schedule. A live person answers at (361) 209-8857. We book a time that works for you, and you get a live trackable arrival window before we come out. No four-hour guessing games.
- 2
On-site roof assessment. Dylan Pace or one of our lead techs walks every slope, checks the decking from the attic, and documents everything with photos. We measure, we count squares, and we note every penetration.
- 3
Written line-item quote. You get a written price before any work starts. It lists the shingle line, underlayment, flashing, venting, decking repair allowance, and labor. If your roof is simple, the number stays simple.
- 4
Material ordering and delivery. We order your Owens Corning shingles along with matching ridge caps, synthetic underlayment, and ice and water shield for valleys and penetrations. We schedule delivery the day before tear-off so nothing sits in your driveway for a week.
- 5
Tear-off and installation. We strip the old roof, repair or replace damaged decking, install underlayment, then shingles. We install to Owens Corning specs and San Antonio code. Photos before and after go to your phone.
- 6
Final inspection and digital invoice. We walk the roof with you if you want, show you what we did, and send a digital invoice by text. The 365-Day Done Right Promise is included in writing, covering every part of the install for a year.

AfterWhy San Antonio Homeowners Call Crestview Roofing Co San Antonio for Owens Corning Work
We founded Crestview Roofing in 2000 with one idea: the roofing business is full of people who say one thing and do another, and we didn’t want to be that company. Every Owens Corning installation we do is bound by The Relay Visibility Guarantee: a written price before work starts, before-and-after photos, a live arrival time, and a digital invoice by text. We also carry GAF and CertainTeed, so if an Owens Corning shingle turns out not to be the right fit for your roof profile or budget, we’ll tell you straight instead of steering you into what’s easiest for us.
Every promise we make goes in writing, because a handshake doesn’t keep water out. If a repair fails within 365 days, we return and correct it at no charge. Free second visit, no negotiation. That’s the 365-Day Done Right Promise, and it’s included with every job at no extra cost.
FAQs
No. Owens Corning warranties are tied to the shingle and the installation method, not to any dealer relationship. As long as the shingles are installed to the manufacturer’s published specs, the warranty applies. We install to spec and document the process with photos, so you have a record if a warranty claim ever comes up.
Most full roof installations take 2 to 4 days once materials are delivered. Weather delays happen, but we don’t drag a job out to fill a schedule. You’ll know the timeline before we start, and we keep it in writing.
That depends on the roof’s age, the decking condition, and how much damage exists. If your Owens Corning roof is under 10 years old and the decking is solid, a repair is often the right call and will usually run $450 to $900. If the roof is 15-plus years old and you’re seeing granule loss across multiple slopes, replacement gives you more value. We’ll show you photos of both options and let you decide with real numbers in front of you.
Yes. We pull all required permits for roof replacement in San Antonio and the surrounding areas. The permit is listed as a line item on your written quote, and we don’t start work until it’s approved. If a roofer tells you a permit isn’t needed for a full replacement, call someone else.
It won’t change unless we find damage that could not reasonably be seen during the initial inspection, like rotten decking hidden under shingles. But even that is priced per sheet in your quote, so you know the cost before a single piece of plywood gets pulled. No change orders invented on the spot. Call (361) 209-8857 for an exact quote, free.
