Roofing in San Marcos, Texas
If you live in San Marcos, you know the feeling of floating down the river on a July afternoon, the spring-fed water staying cold no matter how hot it gets above. That's the kind of thing that keeps people here. A leaking roof is not.
San Marcos is a college town with a river running through it. Between Texas State, the outlet malls, and the square downtown, the energy here is younger than a lot of Central Texas — but the bones of the town are old. We see a little bit of everything when we roof in San Marcos: 1920s bungalows in the historic district with 1x6 plank decking and steep gables, 1980s tract homes in the Willow Creek area, newer builds in Kissing Tree and Blanco Vista, and ranch properties out toward Wimberley Road.
A Note From the River People
The San Marcos River rises from the San Marcos Springs right on the Texas State University campus — the second-largest spring in Texas — and joins the Blanco River just south of town. Spring Lake, fed by those springs, is where the glass-bottom boats at the Meadows Center have been running for generations. Locals tube the river all summer, and the water stays a steady 72 degrees year-round.
What We Do in San Marcos
3 Rivers Roofing offers a full range of exterior services to homeowners and property owners in San Marcos. Below is the short version of each — if you want the long version, click through to the dedicated service page.
Roof Replacement
Roof replacement in San Marcos means doing the job the right way: tear-off down to bare decking, inspect and repair anything rotten or sagging, install the full modern system (synthetic underlayment, ice and water shield, drip edge, starter strip, field material, ridge vent, ridge cap), and leave the property cleaner than we found it.
Roof Repair
Repair work is the unglamorous side of roofing, and it's where a lot of San Marcos homeowners get taken advantage of. We do repairs right: honest assessment, written estimate, correct materials, warranty on the workmanship. If your roof doesn't need replacement, we'll tell you that.
Standing Seam Metal
Standing seam metal is the longest-lasting roof you can put on a San Marcos home. We install both snap-lock and mechanically-seamed (double-crimp) standing seam systems in 24-gauge Galvalume with Kynar 500 finishes that hold their color through decades of Texas sun. A metal roof installed correctly in San Marcos will likely be the last roof your home ever needs.
Atlas Shingle Roofing
Shingle roofs in San Marcos don't all have to be created equal. We install Atlas Pinnacle Pristine architectural shingles with HP42 technology, Class 3 impact resistance, a 130 mph wind warranty, and 3M Scotchgard Protector against algae streaks. The full system — not just the shingles — is what makes the difference.
Seamless Gutters
We install custom-formed seamless gutters on San Marcos homes as a standalone project or alongside roof replacements. Heavy-gauge aluminum, factory-baked color finishes, hidden hangers driven into solid wood, and downspouts sized for the actual roof area — not one-size-fits-all.
James Hardie Siding
James Hardie siding is a long-term upgrade for San Marcos homes — and when it's installed correctly, it's one of the last exterior updates a home will ever need. We install to Hardie's specification down to the last fastener and finish detail.
We also handle commercial roofing for San Marcos-area warehouses, retail properties, churches, and multi-family buildings. For San Marcos property owners and facility managers, we install TPO, modified bitumen, standing seam metal, and commercial shingle systems on warehouses, retail centers, churches, and multi-family buildings. Commercial roofs have different failure modes than residential, and we approach them accordingly.
About San Marcos — and Why We Love Working Here
San Marcos has roughly 27,000 housing units, and a mix of owner-occupied homes, student rentals, and investment properties. That means we work with a wide range of customers: homeowners doing a once-in-30-years replacement, landlords maintaining rental stock, and property managers handling portfolios.
The San Marcos economy is anchored by Texas State University, Central Texas Medical Center, the San Marcos CISD, and the outlet mall corridor along I-35. When we work in San Marcos, we work on homes owned by people who depend on those employers and on the stability of this community — and we approach every job with that in mind.
Our office is at 301 S. Johnson Avenue — literally in the middle of town. If you see our trucks, you're probably seeing us on the way to or from a job a few blocks from home base.
