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.
Hail performance
Metal can still dent from hail, and cosmetic dents are not always functional damage.
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. 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 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.

Yes — Energy Star-rated cool metal roofing reflects 25–40% more solar energy than dark asphalt shingles. Attic temperatures typically drop 10–20°F, which reduces AC runtime through San Antonio summers.

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.

40–50 years on Galvalume, 50+ on aluminum in coastal exposures. Paint systems (Kynar 500 / PVDF) carry 30–40 year finish warranties.

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.

Standard metal warranties exclude cosmetic denting. If dent-resistance matters to you, spec 24-gauge standing seam with striated or ribbed panels — the profile hides minor impacts.

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 2–3× longer. On a 30-year ownership horizon, metal wins on cost per year. Our roof replacement page covers how the job runs with either material.

Most modern subdivisions allow standing seam in muted colors (matte black, dark bronze, charcoal). Older HOAs vary — we verify before ordering.

Any Energy Star cool-rated color works. Medium tones (Sierra Tan, Weathered Copper, Slate Gray) reflect well and hide dust between rains.
