Why Austin Homeowners Choose Owens Corning Roofing
We provide Owens Corning repair in Austin, TX, and we do it differently than most crews: every technician who arrives is background-checked, uniformed, and photo-badged, with their name and photo sent to you before they knock. We service Owens Corning Duration, Oakridge, and Supreme shingle roofs throughout the Austin area, from central neighborhoods to Round Rock and beyond. As an independent Owens Corning service provider, we’re not tied to any manufacturer sales quota, which means our repair recommendations are based on what’s actually happening on your roof, not what we’re incentivized to sell. Call (361) 202-8874 for a written estimate before any work begins.
Why Trust Mercer Roofing Co Austin for Your Owens Corning Roofing?
Our technicians spend their days on Roof Repair jobs across Austin, and that matters when it comes to diagnosing what’s actually wrong. Grant Whitlock, who leads our Austin crew, learned the roofing trade at Los Angeles Trade-Technical College before spending decades on everything from flat commercial decks to steep residential pitches. He and his team have been working on Austin homes for years, including longtime work in Zilker where summer hail has a way of humbling even well-built roofs. That field experience means we know which Owens Corning components fail under Texas UV, which repairs hold up, and which ones are a waste of your money.
When we repair an Owens Corning roof, we use Owens Corning-branded matching shingles, ridge caps, and underlayment where available because color and warranty alignment matter for a clean patch. For non-cosmetic components like vent boots and flashing, we use high-grade aftermarket metal and rubber parts that actually outperform the originals in central Texas sun. We’re independently owned and operated, part of the Threshold Group family founded in 2000, and held to the Threshold Verified standard: every technician is background-checked, identity-verified, and dispatched under a written quality framework. Before any work starts, you get a written price. After the work is done, you get a written guarantee. That’s not marketing language; it’s how we’ve operated since day one.
And yes, we know what it’s like to wonder who’s actually going to show up at your door. We send you the technician’s name and photo before the visit. They arrive in a clean, marked uniform with a photo ID badge. If you’re home alone, or your kids are napping, or you’ve been burned by a contractor before, you’ll know exactly who you’re opening the door to. Your roof shouldn’t be something you worry about – that’s what we’re here for.

Common Owens Corning Roofing Problems We Fix in Austin
- Nail pops and lifted shingle tabs on Duration Series slopes. The Duration line uses SureNail technology, but central Texas hail can still force nails upward through the shingle surface, especially near eaves where wind uplift is strongest. We see this frequently on Duration roofs in Austin after a spring storm: the shingle looks intact from the ground, but a nail head is pressing against the asphalt layer from underneath, creating a water entry point. We remove the damaged shingle, reseat the nail, and replace the shingle with a color-matched Duration piece.
- Granule loss on Oakridge Series shingles with south-facing exposure. Oakridge shingles hold up well, but Austin’s intense UV exposure accelerates granule shedding on any south-facing slope. Once the asphalt coating is exposed, it oxidizes quickly in the Texas heat. We can repair localized granule loss on Oakridge roofs by replacing the affected shingles, but if the granule loss covers most of a slope, we’ll tell you honestly that patching is a holding action, not a fix.
- Cracked and pulled-away vent boot gaskets on low-slope sections. Austin has a notable portion of mid-century modern and ranch homes with low-slope or flat roof sections. On these roofs, the rubber gaskets around plumbing vents dry out, crack, and pull away from the Owens Corning decking, creating a slow leak that stains ceilings. This is one of the most common Owens Corning roof leaks we repair in Austin, and it’s usually a same-day fix with a UV-stable replacement boot.
- Starter strip misalignment and edge curl on older Supreme installations. The Supreme line is a three-tab shingle, and older Supreme installations in Austin sometimes show edge curl along the eaves, especially when the original starter strip was misaligned. Edge curl creates a wind catch, and a strong Austin storm can peel the shingles back. We replace the starter strip and resecure the shingle edges before wind damage turns into water damage.
- Flashing failures at valleys and chimneys on Owens Corning roofs. Valley flashing and chimney flashing are metal, and they fail differently than shingles: they corrode, pull loose, or develop gaps. We see this on Owens Corning roofs across Austin, especially on homes in Allandale and Crestview where the original roof decks often lack plywood sheathing. The flashing pulls away from the spaced board sheathing, and water finds its way under the shingles. We repair valley and chimney flashing with high-grade aftermarket metal that handles Texas UV better than the original.
Owens Corning Parts & Our Repair-vs-Replace Approach
We install Owens Corning-branded matching shingles, ridge caps, and underlayment when the repair is cosmetic and the roof still has life in it. Color match matters: a mismatched patch on the front slope of an Austin home is visible from the street, and it hurts resale value. For non-cosmetic components like vent boots, flashing, and decking seams, we use high-grade aftermarket metal and rubber parts that outperform the originals under Texas UV exposure. The original vent boot on an Owens Corning roof is often the first thing to fail in Austin’s climate; a UV-stable aftermarket replacement will outlast it.
The Owens Corning repair in Cedar Park call comes down to one question: what does the decking look like? If the shingles are failing but the decking is solid, we patch. If the decking is spongy or water-damaged, patching is a false economy, and we’ll tell you that plainly. We’d rather give you a straight answer than invoice you for work that won’t hold. Call (361) 202-8874 and we’ll walk you through what we find.
Our Owens Corning Service Process – Step by Step
- 1
Diagnosis. We inspect the roof from the deck and the attic, looking for Owens Corning-specific failure patterns: nail pops on Duration slopes, granule loss on Oakridge south faces, vent boot cracks on low-slope sections. We photograph everything and show you what we found in plain language.
- 2
Written estimate. Before any work starts, you get a line-item written price. No verbal estimates, no “we’ll see what we find once we tear it open.” The price is the price.
- 3
Repair or install. We install Owens Corning-branded matching shingles and ridge caps for cosmetic work; for flashing, vent boots, and decking seams, we use aftermarket parts built for Texas UV. Every technician is background-checked, uniformed, and photo-badged – the Threshold Standard.
- 4
Test and verify. We check the repair with water testing where needed, verify shingle adhesion and alignment, and document the finished work.
- 5
Written warranty. Every repair includes a written guarantee, backed by our 365-Day Done Right Promise. If the work isn’t right within a year, we make it right. A free second visit is included if a repair fails.

AfterOwens Corning Products We Service & Install in Austin
We service and install the full Owens Corning line that matters for Austin homes: the Duration Series shingles with SureNail technology, the Oakridge Series for long-term performance on steep residential pitches, the Supreme three-tab line for older homes and budget-conscious replacements, and ProEdge Hip & Ridge Cap Shingles for clean roof edges. We stock commonly needed Owens Corning matching shingle colors locally for fast repair turnaround across greater Austin, and we can source any other line quickly when a full replacement is the right move.
We Also Service These Brands
We work on more than Owens Corning roofs. Our Austin crews also service and install GAF and CertainTeed shingle systems, plus IKO, Atlas, Tamko, and Boral. That multi-brand experience matters because it means we’re not locked into one manufacturer’s style or install quirks. We consider the roof you have, the conditions it faces, and the budget you’re working with – not a brand loyalty card.
FAQs – Owens Corning Roofing Service in Austin
Yes, if you want the repair to blend in. Color matching across manufacturers is unreliable, and a mixed patch on a visible slope looks like exactly what it is: a patch. We stock commonly needed Owens Corning Duration colors locally so we can match your roof without waiting on a special order.
It depends on how far the granule loss has progressed. If it’s isolated to a few shingles, we replace them. If the granule loss covers most of a south-facing slope – which we see regularly in Austin after several years of intense summer sun – replacing individual shingles won’t hold up, and we’ll recommend a slope replacement with new Oakridge or Duration shingles. Call (361) 202-8874 and we’ll give you an honest read.
Because hail impact creates small punctures or cracks in the shingle surface that are too small to let water through during a light rain, but open up when a heavy Austin downpour saturates the roof. We see this on Duration and Oakridge roofs after spring hailstorms: the shingle looks intact, but impact damage is letting water through the cracks. We inspect the roof after any significant hailstorm to catch impact damage before it becomes a ceiling stain.
Yes, in most cases, you can repair just the valley. We remove the shingles along the valley, replace the metal flashing with a high-grade aftermarket piece, and reinstall the surrounding Owens Corning shingles. If the shingles along the valley edge are heavily damaged or delaminating, we may recommend replacing those few courses, but you don’t need a full tear-off just because a valley failed.
Yes, if the water damage is localized. We remove the shingles around the chimney, cut out the rotted decking, install new plywood or OSB, add peel-and-stick membrane over the seams, and reinstall the shingles. The shingles themselves often have years of life left; the decking failure is what’s causing the problem. Call (361) 202-8874 for a written estimate of the decking repair scope.
Owens Corning repair in San Marcos typically runs $350 to $900 for localized fixes like shingle replacement, vent boot replacement, or flashing repair. A full Owens Corning Duration roof replacement in Austin generally falls between $9,500 and $16,000 depending on roof size, pitch, decking condition, and tear-off requirements. The honest answer is that we can’t give you a real number without seeing the roof. Call (361) 202-8874 and we’ll come out, inspect it, and give you a written line-item price before any work starts. Estimates are free.
