Metal Roofing in San Antonio, TX: the roof you install once.
A properly installed metal roof will outlast three asphalt roofs, shed hail better, and knock summer attic temperatures down. In Hill Country weather, it's the long-term play.
Why metal makes sense here
Metal roofing costs more up front than asphalt, but the lifecycle math is hard to argue with. A properly installed standing-seam roof lasts 40–60 years — long enough that most homeowners install one and never buy another roof. Compare that to two or three shingle replacements in the same window.
In Central Texas the case gets stronger. Metal reflects rather than absorbs solar heat, which drops attic temperatures 20–30°F in July — that's real money off your cooling bill. Class 4 impact-rated metal also handles hail far better than any asphalt product, which most carriers reward with a discount on your homeowner's premium.
Metal also does something asphalt can't: it sheds embers. In a state where wildfire risk keeps growing along the Hill Country's western edge, that matters.
Not every metal roof is the same.
The two systems we install look similar from the road but behave very differently over time. Here's the honest tradeoff:
Standing seam
Concealed fasteners, panels lock together at raised seams. 40–60 year lifespan. Higher cost, best-in-class weather resistance, minimal maintenance.
Exposed fastener (R-panel / 5V)
Screws visible through the panel face. 25–40 year lifespan. Lower cost, faster install — but screws and gaskets need re-torquing every 10–15 years as they weather.
Stone-coated steel
Metal panels finished to look like shingles or tile. Lifetime durability with traditional curb appeal. Middle of the price range.
How it goes, start to finish.
- 01
Consult & material walk-through
We'll bring physical samples — color, gauge, profile — so you can see and feel the panel options in your driveway.
- 02
Detailed measure & quote
Metal is engineered to your specific roof; measurements and pitch drive panel length and trim.
- 03
Order & fabricate
Panels are cut to your roof's exact runs. Typical lead time is 2–4 weeks for standing seam.
- 04
Tear-off & install
Full tear-off, new underlayment (high-temp synthetic for metal), then panels and trims. Most homes complete in 3–6 days.
- 05
Manufacturer warranty registration
We register your paint and substrate warranties directly with the manufacturer — up to 40-year finish coverage.
What a metal roof runs
Metal roofing in the San Antonio market typically runs $18,000–$45,000 installed, depending heavily on system, gauge, and home size. Standing seam is roughly 2–3× the cost of standard asphalt; exposed fastener is roughly 1.3–1.8× asphalt.
Metal is priced per project after an on-site measure. We'll walk you through standing-seam and exposed-fastener numbers side by side so you can compare on lifecycle cost, not just sticker.
What affects the number
- System type (standing seam, exposed fastener, stone-coated)
- Panel gauge — 24-gauge is the residential standard; 22-gauge is heavier and more expensive
- Color and finish — Kynar-500 finishes carry longer warranties and cost more than SMP
- Roof complexity — hips, valleys, and dormers add trim work, which is where metal labor concentrates
- Whether it's a metal-over-shingle install (only recommended in limited cases) or full tear-off
Is a metal roof worth it in Texas?
Worth it if you plan to stay in the house long enough to use the extra service life, and not worth it if you are moving in a few years. Metal in this market typically runs $18,000 to $45,000 installed against $8,000 to $22,000 for asphalt, so the payback is time, not cash back.
What you get for the difference is a roof that handles heat and wind better, sheds water faster, and does not shed granules. Standing seam has no exposed fasteners to back out, which is the failure point that ages an exposed fastener roof.
The honest case against: if you are selling soon, or you are stretching to afford it, a well installed architectural or impact resistant shingle roof protects the house just as well for now. Nobody has ever regretted buying the roof they could pay for.
Hail is worth knowing about before you commit. Metal resists puncture well, but a hard hail event can dent panels, and dents are cosmetic damage that some policies exclude. Ask your agent how cosmetic damage is treated before you buy.
Does a metal roof lower cooling bills in San Antonio?
It helps, and it is not the whole answer. A reflective metal finish over a properly ventilated attic keeps a lot of solar heat out of your attic, which shows up as less work for the AC in July and August.
How much you save depends on what you have now. If your attic is under insulated and poorly vented, most of your savings are sitting in the attic, not on the roof, and insulation is the cheaper fix to make first.
We do not put a percentage on it because your house, your ductwork, your shade, and your thermostat habits change the number more than the panel does. Any roofer quoting you an exact savings figure is guessing.
If a lower summer bill is your main goal, ask us to price attic insulation and ventilation alongside the roof. That combination is where the difference is actually felt.
Questions we hear often.
Is a metal roof noisier in rain?
No — that's the barn myth. A metal roof installed over solid decking with proper underlayment is no louder than shingle inside your home. The difference only shows up on open-frame structures like barns and pavilions.
Will it rust?
Modern metal roofing uses Galvalume steel or aluminum with baked-on Kynar or SMP finishes. Under normal conditions the finish will fade before the substrate ever rusts — and manufacturer finish warranties run 30–40 years.
Can I put metal over my existing shingles?
Sometimes yes, but we usually recommend against it. Full tear-off lets us inspect and fix the decking, install proper underlayment, and gives you the longest-lasting install.
Does metal roofing lower my energy bills?
In San Antonio summers, meaningfully yes. Reflective metal finishes and a properly ventilated system can drop attic temps 20–30°F, which is a noticeable summer cooling savings. It's not a silver bullet, but combined with attic insulation it adds up.
