CertainTeed Roofing Company in Austin: What to Know First
An independent CertainTeed roofing company in Austin handles repairs, replacements, and inspections on homes with CertainTeed shingles, usually completing most repairs within a single visit once parts are on hand. Mercer Roofing Co Austin is an independent CertainTeed service provider, not a manufacturer-authorized contractor, which means we replace what’s worn and repair what’s sound rather than pushing a full tear-off. Most CertainTeed repairs in the Austin market run between $350 and $1,800 depending on what failed, while full replacements on average Austin homes range from $12,000 to $22,000. That’s the honest range, and you’ll get a written price before any work starts.

How CertainTeed Products Fail – and How We Fix Them
CertainTeed makes a solid shingle, but Austin’s weather pattern, with its hail season, sudden temperature swings, and months of UV exposure, finds the weak points in any roof. Here’s what we see on CertainTeed roofs and what we do about it.
- Landmark series granule loss after hail. The Landmark architectural line holds up well generally, but after a hard Austin hailstorm we often find granule loss concentrated on the south and west slopes. Granules are the shingle’s sunscreen. Once they’re gone, the asphalt mat underneath bakes and cracks. We document it, check for the telltale circular impact marks, and replace damaged shingles with color-matched CertainTeed Landmark stock before the mat fails.
- Presidential Shake cupping and wind lift at the rake edge. The Presidential Shake line is thick and heavy, and that thickness makes it more prone to cupping when the decking beneath holds humidity, something Austin’s hot summers make worse. On the rake edges, where the shingle overhangs the gable, we find wind lift that lifts the shingle and lets water under the underlayment. Our fix is removing the cupped shingles, checking deck ventilation, and resecuring the edge with proper nail patterns before resealing.
- XT 25 three-tab cracking along the granule line. The XT 25 is a lighter three-tab shingle, and on older Austin roofs we find horizontal cracking right along where the granules embed into the mat. That’s sun aging combined with the daily expansion cycle. When we see that pattern, the shingle is at the end of its life, and we quote both a patch repair and a replacement, with the written price for each so you decide with numbers in front of you.
- CertainTeed flashing integration failures at dormers and skylights. CertainTeed shingles don’t fail around dormers and skylights more than any other brand, but the flashing integration does fail when the original installer cut corners on step flashing. On CertainTeed roofs in older Austin neighborhoods like Hyde Park, we regularly find missing or reversed step flashing where the dormer wall meets the roof slope. Water channels behind the shingle edge, rots the decking, and shows up as a ceiling stain months later. We pull the affected shingles, replace the flashing correctly, and repair the decking if needed.
- Slope ventilation problems under certainteed ridge caps. If the attic isn’t venting, no shingle brand lasts. On CertainTeed roofs with ridge cap shingles, we check that air can actually move from the soffit intakes to the ridge vent. When the original roofer installed a ridge vent without opening the sheathing slot beneath it, the attic cooks in an Austin summer, and shingles age prematurely. We cut the slot correctly, verify airflow, and it extends the remaining life of the roof.

Our CertainTeed Roofing Company Process
Here’s how a CertainTeed job goes from your call to the final walk-around:
- 1
You call (361) 202-8874 and talk to a person. Not a voicemail. You describe what you’re seeing, and we schedule a visit.
- 2
We send you the technician’s name and photo before arrival. When the tech knocks, they’re wearing a clean uniform and a photo ID badge. You’ll already know who they are.
- 3
The tech inspects the roof and tells you what’s actually wrong. We don’t guess from the ground. We get on the roof, look at the shingles, the flashing, the underlayment, and the decking in the affected area.
- 4
You get a written price before any work starts. Line-item, specific, and honored. If the scope changes, you approve the change in writing before we touch it.
- 5
We do the work using the right parts for a CertainTeed roof. That means OEM CertainTeed shingles when appearance and warranty matter, and quality aftermarket flashing and underlayment components when they perform equivalently or better at a lower cost.
- 6
We test, document, and give you the written 365-day guarantee. Every repair carries it. If something’s not right within a year, we come back and make it right, free of charge.

AfterWhat CertainTeed Roofing Company Costs in Austin
CertainTeed roofing costs in Austin depend on what failed and how far the damage runs. Here are real ranges for the jobs we handle most often:
| Job | Typical Cost Range in Austin |
|---|---|
| Replacing 5-10 damaged CertainTeed Landmark shingles (hail or wind) | $350 – $750 |
| Flashing repair at a dormer, skylight, or chimney on a CertainTeed roof | $450 – $1,200 |
| Ventilation correction (opening ridge vent slot, addressing soffit intake) | $600 – $1,500 |
| Partial decking replacement with shingle replacement over the repaired area | $1,200 – $2,800 |
| Full CertainTeed roof replacement on a typical 1,800-2,400 sq ft Austin home | $12,000 – $22,000 |
What moves the price is the size of the affected area, the condition of the decking beneath, whether the roof is a steep pitch, and how much of the existing flashing is reusable. You’ll see every dollar itemized before you approve a thing. Call (361) 202-8874 and we’ll give you an exact written estimate for your roof.
