Roofers in San Marcos, TX
Roofers in San Marcos, TX work on homes that face a specific set of challenges: Hill Country hailstorms, flash-flood rainfall, and a housing stock that ranges from 1920s bungalows to brand-new subdivisions. Whether it’s granule loss on a 1980s ranch house near the university or a full replacement on a pier-and-beam home downtown, the job starts with a roof that drains fast and holds up to impact. We’re Mercer Roofing, and we serve San Marcos homeowners with upfront written pricing and a 365-Day Done Right Promise on every repair. Call (361) 202-8874 to talk through what your roof needs.
Why San Marcos Homes Are Different
San Marcos sits on the edge of Flash Flood Alley, which means roofs here don’t just shed water – they get hit with it. Rapid, heavy rainfall in spring and fall, often paired with large hail, causes granule loss on composition shingles and shingle blow-off along roof edges. Homes in older neighborhoods east of Texas State University frequently have original cedar shake or three-tab shingles laid over spaced decking, which makes hail splits common and full redecking a regular part of any replacement. The 1970s and 80s ranch-style homes across town often have low-slope roofs that need careful attention to valley and penetration flashing, since standing water after a downpour finds every weak point. Meanwhile, newer subdivisions built since the 2000s typically use composition shingles, and hail impact remains the leading cause of insurance claims. A roofer in San Marcos has to understand all of it: the old and the new, the steep and the low-slope, the original and the already-patched.
Styles & brands we work with
Our Main San Marcos Services
San Marcos homeowners call us most often for repairs after a storm and for full replacements when an older roof has reached the end of its life. Here’s what each service looks like in San Marcos, with a dedicated page for the details.
Roof Repair in San Marcos
Most repair calls in San Marcos start the same way: a storm rolled through, and now there’s a water stain on the ceiling or granules in the gutter. Hail splits shingles, wind lifts them, and the valleys and flashings on older ranch homes take the brunt of it. We locate the actual source of the leak – not just the visible damage – and give you a written price before any work begins. Every Roof Repair in San Marcos job includes a written guarantee and a free second visit if the repair doesn’t hold.
Roofing Company in San Marcos
When homeowners search for a Roofing Company in San Marcos, they’re usually looking for one crew that can handle whatever the roof throws at them, from a quick flashing fix to storm response. That’s what we do. Our technicians arrive in marked uniforms, present a photo ID badge at the door, and we send their name and photo to you before they show up. It’s a simple way to know exactly who’s at your house before you open the door.
Roof Installation in San Marcos
A new roof in San Marcos isn’t just shingles over the old decking. When we install, we check what’s underneath first: the decking, the underlayment, the flashing. Homes east of the university with spaced decking often need full redecking before new materials go down, which we quote in writing before any work starts. We install GAF, CertainTeed, Owens Corning, and IKO shingle systems, all on a written Roof Installation in San Marcos contract with no surprises on the invoice.
