Asphalt Shingles vs Metal Roof Cost in San Antonio — What Homeowners Should Know
TL;DR
Architectural shingles cost $5 to $8 per square foot installed and standing seam metal $10 to $14, so a typical home runs $10,000 to $12,000 in shingles versus $20,000 to $28,000 in metal. But shingles last 15 to 20 years here while metal lasts 40 to 70, which makes metal roughly $450 per year of roof life versus $650 for shingles. Your ownership timeline decides which math applies to you.
The sticker prices are easy: shingles cost less, metal costs more. The real comparison is what each roof costs per year it protects the house, and in a climate that shortens shingle life, that math is closer than most homeowners expect. Here are the actual numbers.
How much does each roof cost installed?
Architectural asphalt shingles run $5 to $8 per square foot installed in Texas, which puts a typical 2,000 square foot home around $10,000 to $12,000. Standing seam metal runs $10 to $14 per square foot, or roughly $20,000 to $28,000 for the same home. Budget metal profiles like corrugated panels start lower, around $4.50 to $6.50 per square foot.
| Cost factor | Architectural shingles | Standing seam metal |
|---|---|---|
| Installed cost per sq ft | $5 to $8 | $10 to $14 |
| Typical 2,000 sq ft home | $10,000 to $12,000 | $20,000 to $28,000 |
| Realistic local lifespan | 15 to 20 years | 40 to 70 years |
| Cost per year of roof life | about $650 | about $450 |
| Replacements over 50 years | 2 to 3 | 0 to 1 |
The row that matters is cost per year. Shingles here realistically deliver 15 to 20 years before heat and hail end them, while metal delivers 40 to 70. Spread each roof over its life and metal comes out cheaper per year of protection, plus the shingle path includes living through two or three more replacements, each at whatever prices look like in 2045.
Why do shingles cost more here than the sticker shows?
Because our climate taxes them. Heat cooks the flexibility out of asphalt, hail bruises what heat made brittle, and the local lifespan lands about five years short of national averages. That means the 20-year shingle roof you priced is usually a 15-to-18-year roof in practice, which quietly raises its true cost per year. Metal gives nothing back to the heat, and Class 4 impact-rated metal shrugs off hail that totals asphalt shingles.
There are two more line items worth asking your insurer about. Some Texas carriers discount premiums for Class 4 impact-resistant roofing, which favors metal, and cosmetic-damage exclusions sometimes apply to metal roofs, which is worth reading before you buy. Reflective metal also trims summer cooling bills, a real number in a place with 160-plus days over 90 degrees in a hot year.
When do asphalt shingles still make sense?
Often. If you plan to sell within ten years, shingles let the next owner buy the replacement. If the budget is fixed and the roof is failing now, a quality architectural shingle install protects the house for less than half the upfront cost. And a properly installed GAF shingle system carries warranty coverage that most homeowners never come close to using up before they move.
What changes the math is a bad install. A poorly nailed shingle roof can fail in 8 to 10 years, and at that lifespan shingles lose to everything. Installation quality is the multiplier on whichever material you pick, which is why the contractor question matters more than the material question. As a GAF Master Elite® contractor, our shingle installs qualify for the Golden Pledge® warranty, the strongest coverage GAF offers.
When is metal worth the premium?
When you plan to stay past year 15, when hail keeps finding your neighborhood, or when this is the last roof you want to buy. Metal wins the long game on every line: lifespan, hail resistance, cooling costs, and resale. The standing seam systems we install carry manufacturer warranty coverage measured in decades, and unlike shingles, metal holds its 40-to-70-year lifespan in this climate instead of surrendering years to it.
One honest caveat: metal costs more to repair when something does penetrate it, and finding the leak in a standing seam system takes more skill than swapping a shingle. Pick metal for the decades, not because it never needs attention.
Which roof should you actually pick?
Run your own numbers on three questions. How long will you own the house? If under 10 years, shingles usually win. Does your area take regular hail? If yes, impact-rated metal plus a possible insurance discount closes the price gap faster. Is this roof replacing one that failed early? Then fix the cause, often ventilation, before spending on either material, because a cooked attic ages both.
We quote both materials on the same inspection, with the lifetime math side by side, and the honest answer differs house to house. What we won’t do is sell metal to someone moving in five years or shingles to someone who never wants to reroof again.
