Why Mercer Roofing Co San Antonio Is San Antonio’s Preferred Roofing Company

San Antonio homeowners deal with something most roofing markets do not: a predictable annual hailstorm season that brings out-of-state crews door-knocking within 48 hours. That is why it matters that Mercer Roofing Co San Antonio is not a truck with an out-of-state plate. We are part of the Threshold Group family, founded in 2000, and each location is independently owned and operated. Our San Antonio office is led by Grant Whitlock, and our crews live and work in the metro area year-round, not just in June.

Every technician who steps onto a San Antonio property is background-checked, identity-verified, and badged. The name and photo of the person coming to your home is sent before they arrive. That is the Threshold Verified standard, and we do not waive it. Homeowners raising young kids along the 78250 corridor, older residents in Terrell Hills, and anyone home alone during the day should not have to guess who is at the door.

We hear from San Antonio customers after storms, during the brutal July-August heat when flashing fails, and in the fall when people finally inspect what the spring storms did. The feedback is consistent: the written price matched the invoice, the crew showed up on time, and the badge at the door made the difference.

Roofing Contractor in San Antonio

A Roofing Contractor in San Antonio does more than nail shingles. We assess decking, flashing, underlayment, ventilation, and drainage. On a repair, that means finding the actual leak, not just sealing the visible stain. On a replacement, it means pulling old material and exposing what the last contractor covered up. San Antonio homes built in the 1970s through 1990s often have plywood decking that has absorbed decades of humid summers and hail impacts. A patch job hides that damage. We expose it, document it, and price the fix before work begins.

Decking and Structural Repair

When hail cracks plywood decking or a leak has rotted the substrate, this is structural work. San Antonio requires a permit for structural changes, including re-decking. A cheap quote that skips the permit leaves you unprotected if the city later flags the work. We pull the permit, coordinate the inspection, and put the passed sign-off in your file. That documentation matters when you submit an insurance claim.

Full Replacements Done to Hail-Country Spec

We install architectural shingles from GAF, CertainTeed, and Owens Corning rated for San Antonio’s 130 mph wind requirement. That is what the code asks for, and what most insurance carriers look for when they apply premium discounts. A 3-tab shingle does not carry the same rating. The difference in material cost is real, but so is the difference in how the roof survives the next supercell.

Roof Inspection in San Antonio

A Roof Inspection in San Antonio is the cheapest insurance you will buy. For $150 – $350, a trained technician walks your roof, tests flashing, checks drip edge, and documents granule loss. San Antonio’s hot, humid summers accelerate granule loss on asphalt shingles. Hailstorms compound it. By the time a homeowner notices a ceiling stain, the decking underneath has often been wet for months.

Post-Storm Inspection

After any hailstorm hits your zip code, book an inspection within a few weeks. Your insurance adjuster will look at your roof, but adjusters are generalists. A roofing contractor looking at the same roof with hail damage in mind will flag impact bruising, lifted shingles, and cracked sealant strips that a general inspection might miss. We photograph everything and provide a written report you can hand to your carrier.

Pre-Purchase Inspection

If you are buying a home in Schertz, Cibolo, or anywhere in the San Antonio metro, the home inspector’s roof summary is usually one paragraph. We go deeper. We check the age of the shingles, whether the roof has been repeatedly patched, and whether the decking shows signs of water intrusion. That report tells you whether you are buying a house or a roofing project.

Trusted Brands We Service in San Antonio

We install and repair roofing systems from GAF, CertainTeed, and Owens Corning. These are manufacturer-recognized brands, not off-label imports. Because our San Antonio office stocks common components locally, we can source matching shingles, ridge caps, and flashing quickly. If you have a GAF roof and need a repair before the next storm, we are not waiting a week on a freight truck. Our technicians know which products carry the wind ratings San Antonio code requires, and we will put that in writing on your quote.

Common Roofing Company Problems We See in San Antonio Homes

• Hail-impacted shingles that look fine from the ground. San Antonio’s spring supercells drop hail large enough to bruise the mat under the shingle surface. From the curb, the roof looks fine. From the ladder, we see impact craters and cracked tabs that will fail within two years.
• 3-tab shingles installed where architectural shingles are required. Some cheap replacement jobs use 3-tab material because it costs less per square. That material does not meet the 130 mph wind rating San Antonio expects. It will lift in the first strong storm.
• Missing ice and water shield in valleys and around penetrations. San Antonio downbursts are short and violent. Water gets driven uphill under shingles. Without ice and water shield in valleys and around pipe boots, the next downpour finds the seam.
• Storm chaser repairs that skip permit checks. After a hail event, out-of-state crews blanket neighborhoods like Stone Oak and Alamo Ranch. They patch, they collect, they leave. Months later, the homeowner discovers decking damage that was never documented, and the insurance company denies the claim because the structural work was never permitted.
