CertainTeed Roof Installation Nationwide

CertainTeed Roof Installation in San Antonio: What to Know First

CertainTeed roof installation in San Antonio typically runs $11,500 to $24,000 for a full tear-off and replacement on an average 1,800-square-foot single-story home, and most jobs take three to five working days from tear-off to final inspection. We’re an independent CertainTeed service provider, not a manufacturer-authorized dealer, which means our recommendations are based on what actually holds up on San Antonio roofs, not what a brand rep wants us to push. This page is for homeowners who own a CertainTeed roof, are planning one, or are trying to figure out whether the quote in front of them is honest. Call (254) 276-4369 and a real person answers, day or night.

How CertainTeed Products Fail, and How We Fix Them

CertainTeed makes a solid shingle. Landmark is a workhorse on San Antonio homes from Stone Oak to Alamo Heights, and Landmark Pro’s heavier fiberglass mat holds up better to hail than the base line. But no shingle fails in a vacuum. The stuff around it fails first, and that’s where we spend our time on an installation. These are the five failure modes we see most on CertainTeed roofs in this city.

• Pipe boot flashing pulls away from the shingle layer. On CertainTeed roofs installed before roughly 2015, the rubber collar at plumbing vent pipes degrades faster in San Antonio’s UV than in cooler climates. The shingle above is usually fine. We strip back the shingles around the vent, install a new flexible lead or rubber boot, weave the CertainTeed shingles back over it, and seal the seam with manufacturer-specified adhesive. It’s a half-day job most of the time, not a full roof replacement.
• Valley flashing corrosion at center-cut valleys. CertainTeed’s installation guides allow center-cut valleys, and on homes where the original installer used thin galvanized metal, we find pinhole rust within a decade. Water follows the valley, rides under the shingle edge, and rots the decking below. Our fix on a re-roof is to switch the valley to a woven or closed-cut configuration with a heavier-gauge metal, which holds up far better in San Antonio’s freeze-thaw-and-bake cycle.
• Nail-pull-through in high-wind exposures. Landmark Pro and Presidential lines carry a 110-mph wind warranty when installed correctly, but installers sometimes use nails that are too short or drive them too hard through the mat. In the Hill Country wind corridors and on two-story homes where gables catch the gusts, we see shingles lifting within a few years. Correct nail placement and length is something we check on every single shingle course, not just the ones you can see from the driveway.
• Improper decking prep on older San Antonio homes. Homes built in the 1970s and 1980s around Alamo Heights and Terrell Hills often have solid 1×6 roof decking with gaps. CertainTeed’s underlayment spec assumes a continuous deck surface, and skimping on prep means the underlayment sags between boards and traps water. We quote decking inspection and repairs as a separate line item so you can see exactly what’s being done, and we don’t bury it as a surprise change order.
• Starter strip and drip edge mismatches from patch jobs. If your CertainTeed roof has had spot repairs over the years, there’s a real chance someone used a different brand’s starter shingle or skipped drip edge entirely along the eaves. That creates a visible seam where the first course sits too high or too low, and wind gets under the edge. We install CertainTeed starter strips and full drip edge on every installation, because the first course is what fails first in a San Antonio thunderstorm if it’s wrong.

Our CertainTeed Roof Installation Process

Here’s how a full CertainTeed installation goes with us, from the first call to the last nail.

1. 1
   Call and schedule a site visit. A live person answers at (254) 276-4369. We schedule a time that works for you, and before the technician arrives, you’ll get their name and photo by text or email. They’ll show up in a clean uniform wearing a photo ID badge.
2. 2
   Full roof assessment and measurement. We inspect the decking, flashing, ventilation, and drainage. We look at the pitch and your neighborhood’s roof profiles so we recommend a CertainTeed line that fits, not just the one we have in stock. Landmark is our default for standard pitches; Landmark Pro or Northgate for high-wind or hail-priority homes; Presidential shake-style for homes where the look matters.
3. 3
   Written line-item price, before any work starts. You’ll receive a quote that separates tear-off, decking repair, underlayment, shingles, flashing, ventilation, and disposal. No “we’ll figure it out later” language. If the decking is worse than expected, you’ll know what the per-sheet price is and approve it in writing before we touch it.
4. 4
   Tear-off and deck prep. We strip the old roof, repair or replace damaged decking, and check that the surface is solid and clean. We don’t install over rotted boards, and we don’t charge for work you didn’t approve.
5. 5
   Installation to CertainTeed spec. Ice-and-water shield in valleys and at eaves, synthetic or felt underlayment per the product line, starter strips, drip edge, and the shingles you chose. We install to wind-nail patterns that match the warranty requirements of the specific CertainTeed line.
6. 6
   Cleanup, inspection, and the written guarantee. We run a magnetic sweep for nails, walk the roof with you if you’d like, and hand you a written 365-Day Done Right Promise covering the workmanship. If you find anything off within a year, we come back and make it right.

What CertainTeed Roof Installation Costs in San Antonio

You’ll hear numbers from $8,000 to $35,000 around San Antonio, and both can be true depending on what’s under the shingles. Here’s what we typically see.

• Basic tear-off and Landmark installation, 1,500 – 2,000 sq ft single-story: $11,500 – $16,000
• Landmark Pro or Northgate, same footprint: $14,000 – $19,500
• Presidential shake-style, same footprint: $18,000 – $24,000
• Decking replacement, per 4×8 sheet if rot is found: $85 – $140 per sheet
• Full roof with new flashing, drip edge, ventilation, and disposal: included in the ranges above, never a surprise line item

What moves the price: roof pitch, number of stories, condition of existing decking, access to the roof, and whether you’re in a homeowner’s association with material requirements. The Alamo Heights area, for example, often calls for specific profiles and sometimes requires heavier architectural shingles. That’s fine. We’ll quote it honestly. Call (254) 276-4369 for a written estimate. It’s free, and you’ll have a number you can actually compare against anyone else in San Antonio.

Why San Antonio Homeowners Call Mercer Roofing Co San Antonio for CertainTeed Work
