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
A cool-rated metal finish reflects more of the sun's heat than dark shingles. Less heat soaks into the attic.
Hail performance
Metal can still dent from hail, and cosmetic dents are not always functional damage. Our standing seam panels are Class 4 impact rated (UL 2218), which can qualify for an insurance discount in Texas depending on your carrier.
Lasts 40–50 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, with mechanically seamed or snap-lock seams, in 24-gauge Galvalume steel. What we specify on custom homes and for 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 40–50 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. If you are planning solar on a standing seam roof, our solar panel detach and reset page covers how the panels come off and go back on.

That's why the same panel from the same manufacturer can last 40–50 years on one house and fail in 10 on another. The system is the details.

Frequently asked

Metal roofing questions

Standing seam runs $23,200 – $37,800 on a typical 2,400 sq ft home at medium pitch, at the same per-square rates our roof cost calculator uses. Exposed-fastener metal on outbuildings is $8–$16 per sq ft installed. Stone-coated steel lands between architectural shingle and standing seam.

It can be. A cool-rated metal finish reflects more of the sun's heat than dark asphalt shingles, so less heat reaches the attic. That can cut AC run time through San Antonio summers. How much depends on the color, your attic ventilation, and your insulation.

Metal can still dent from hail, and cosmetic dents are not always functional damage. Whether a metal roof earns an insurance discount depends on the panel and its tested impact rating. Ask your agent what yours would be. Our hail damage page explains how functional damage is assessed.

Most standing seam roofs on Galvalume steel last 40–50 years when the details are done right. The Kynar 500 (PVDF) paint finish has its own manufacturer warranty, separate from the panel.

No. Over solid decking with synthetic underlayment, a metal roof is no louder than shingles. The barn-roof myth applies to open-purlin construction, not residential.

Yes. Mechanically-seamed standing seam is rated down to 1:12 pitch. Below that we specify TPO or modified bitumen.

Structurally it's possible with 1x4 furring, but we recommend full tearoff for warranty and decking inspection. Central Texas heat degrades hidden shingles quickly.

Metal roofs don't attract lightning any more than other roofs, and being non-combustible they actually reduce fire risk if struck. Grounding is a standard install detail.

Either can qualify for an insurance discount, depending on the product's tested impact rating and your carrier. Class 4 shingle costs less upfront; standing seam lasts about twice as long. On a 30-year ownership horizon, metal wins on cost per year. Our roof replacement page covers how the job runs with either material.

It depends on your HOA. Many deed restrictions set rules for roof color and material. We check your HOA's rules before we order panels.

Lighter colors reflect the most heat. Look for a color with a cool-roof rating from the Cool Roof Rating Council. Medium tones like Sierra Tan, Weathered Copper, and Slate Gray are a middle ground that also hides dust between rains.
