Metal costs more on day one than asphalt in San Antonio—typically about two to three times the installed price of architectural shingles on the same house. On a 2,000 sq ft home, that gap often lands around $8,000 to $18,000 depending on panel type and roof complexity.
Asphalt here usually needs full replacement in 15 to 20 years. Standing seam metal commonly runs 40 to 60 years with light maintenance. Compare price per year of service, not only the check you write today: a $12,000 roof that lasts 20 years is $600 / year; a $22,000 roof that lasts 50 years is $440 / year.
In 2026, local crews are pricing architectural asphalt around $4–$8 / sq ft installed and metal from about $9–$18 / sq ft (corrugated through standing seam). Reflective metal can also cut cooling costs roughly 10–25% in South Texas summers.
By the end of this guide, you’ll know upfront ranges for both systems, how replacement cycles change the math, what maintenance and energy savings add, and when asphalt still makes sense for a short hold.

Upfront Installed Cost in San Antonio
Ranges below include typical labor, materials, tear-off, underlayment, and trim for an average-complexity Bexar County roof.
| System | Installed cost / sq ft | About on 2,000 sq ft |
|---|---|---|
| 3-tab asphalt | $4–$7 | Lower end; weak hail/wind choice |
| Architectural asphalt | $5–$8 | Roughly $10,000–$16,000 |
| Corrugated / exposed-fastener metal | $9–$12 | Roughly $18,000–$24,000 |
| Standing seam metal | $12–$18 | Roughly $24,000–$36,000 |
Pitch, valleys, dormers, and multi-layer tear-off raise both sides. Confirm tear-off, synthetic underlayment, flashings, permit, and manufacturer warranty docs in every quote.
Practical rule: compare options by cost per year of service, not only the day-one invoice.
Lifespan and Replacement Cycles
Manufacturer “30-year” asphalt warranties are defect warranties—not a promise of 30 years in San Antonio UV and heat. Real-world architectural shingles here often need replacement at 15–22 years. Corrugated / exposed-fastener metal: about 30–45 years. Standing seam: about 40–60 years.
| Roofing system | Expected life in San Antonio | Replacements in 50 years | Typical maintenance |
|---|---|---|---|
| 3-tab asphalt | 12–18 yrs | 3–4 | Rising repairs late in life |
| Architectural asphalt | 15–22 yrs | 2–3 | Flashing checks; algae in shade |
| Exposed-fastener metal | 30–45 yrs | 1–2 | Fastener/sealant pass every 10–15 yrs |
| Standing seam metal | 40–60 yrs | 0–1 | Flashing checks about every 10 yrs |
Maintenance and Energy Costs
Isolated asphalt repairs often run $200–$600 per event and become more frequent in the last five years. Metal sealant/fastener events often $150–$500. A full fastener pass on exposed-fastener metal every 12–15 years can cost $1,200–$2,500—planned maintenance, not “maintenance-free.”
Dark asphalt can hit 150–175°F on a July afternoon. Reflective metal can run 50–80°F cooler at the surface. DOE-linked estimates for hot climates put cooling savings around 10–25% with Energy Star–rated reflective metal. On a household spending roughly $250 / month on summer electricity (about half cooling), a 20% cooling cut is on the order of ~$100 / year—meaningful over decades, especially with rising rates. Check CPS Energy rebate schedules when active.
Practical rule: metal is lower maintenance, not zero maintenance—especially with exposed fasteners.
50-Year Cost Comparison
Illustrative 2,000 sq ft San Antonio home (2026 dollars, modest future asphalt inflation):
| Cost category | Architectural asphalt (50 yrs) | Standing seam metal (50 yrs) |
|---|---|---|
| Initial install | ~$13,000 | ~$30,000 |
| 2nd replacement (~yr 18) | ~$17,000 | Not required |
| 3rd replacement (~yr 36) | ~$21,000 | Not required |
| Ongoing maintenance | ~$6,000–$9,000 | ~$3,000–$5,000 |
| Energy savings offset | Minimal | ~$4,000–$8,000 |
| Estimated total | ~$57,000–$63,000 | ~$29,000–$35,000 |
If you sell within 5–10 years, lifetime metal savings may not accrue to you. Fresh asphalt still sells well; metal’s full premium may not appraise dollar-for-dollar. Past about 15 years of ownership—especially with high cooling bills, hail claims, or rental holds—metal usually pulls ahead.
Which System Fits Your Situation
Lean asphalt if: you sell in 7–10 years; cash cannot cover the metal premium; decking repairs already stretch the budget; neighborhood comps will not support a metal premium.
Lean metal if: this is your long-term home; you own a rental and want fewer cycles; cooling bills are high and attic ventilation is solid; hail claims keep hitting asphalt; you can finance the premium at a rate the lifetime savings can cover.
Common Questions About Metal vs Asphalt Cost
How much more is metal than asphalt here?
On a typical 2,000 sq ft home: asphalt about $10,000–$16,000; corrugated metal $18,000–$24,000; standing seam $24,000–$36,000—roughly 2–3× upfront.
Is metal worth it in San Antonio?
For owners staying 15+ years, usually yes—lifespan, maintenance, hail, and cooling close the gap by year 15–20. Under 10 years, asphalt can be the practical call.
How long do shingles really last here?
About 15–20 years in practice, even when the box says 30. Plan replacement near year 20, not year 30.
Do metal roofs cut energy bills?
Yes when reflective and paired with decent attic ventilation—often 10–25% cooling. Dark metal helps less.
Can metal go over existing asphalt?
Often one layer is allowed if the deck is sound, saving roughly $1,000–$2,500 in tear-off. You lose deck inspection; soft or wet deck means full tear-off.
What is the cheapest metal option?
Corrugated or exposed-fastener Galvalume/painted steel around $9–$12 / sq ft installed—closer to high-end asphalt, with fastener maintenance over the life of the roof.
Next Steps for San Antonio Homeowners
Get paired asphalt and metal quotes on the same roof. Ask for lifespan assumptions, fastener maintenance schedules, Energy Star / SRI data, and CPS rebate eligibility. Be honest about how long you will own the house—that drives the answer more than any brochure lifespan.
