Metal Roofing in San Antonio

Standing seam, stone-coated, and exposed-fastener metal systems engineered for Central Texas heat, hail, and 40+ year service life.

Why metal in San Antonio

Built for heat, hail, and the long haul

Central Texas roofs cook. They get pounded. And most homeowners replace them at least once. Metal is the system that changes that math.

Reflects the heat
Cool-rated metal reflects 25–40% more solar energy than dark shingles — attic temps drop 10–20°F.
Handles the hail
24-gauge standing seam is Class 4 impact rated. Most Texas insurers discount the premium.
Lasts 40+ years
Galvalume substrate with Kynar 500 finish outlives 2–3 asphalt roofs. Cost per year wins.
Systems we install

Three metal roofing categories

Standing Seam
The premium choice — concealed fasteners, mechanically or snap-locked seams, 24-gauge Galvalume or aluminum. What we specify on custom homes and long-term owners.
Stone-Coated Steel
Shingle- or tile-profile panels with acrylic-bonded stone granules. Reads as tile from the street, performs as metal. Great for HOA aesthetics.
Exposed-Fastener (R-Panel)
Screw-down panels over purlins. Best for outbuildings, barns, and ranch structures. Concealed-fastener retrofits available for houses with prior R-panel installs.

Engineer's perspective

What separates a metal roof that lasts 50 years from one that leaks in 10

Metal roofing failures are almost never about the metal. They're about substrate prep, fastener selection, panel expansion accommodation, and flashing detail. On a mechanically-seamed standing seam roof, the panel is the easy part — the ridge, hip, valley, and penetration details are where roofers separate.

We specify high-temp synthetic underlayment (not felt), butyl-tape sealed clips, floating panel design that accommodates thermal movement, and hand-formed valley metal — not off-the-shelf 10-foot sections spliced together. Every penetration gets a proper curb flashing, not a rubber boot.

That's why the same panel from the same manufacturer can last 50 years on one house and fail in 10 on another. The system is the details.
