AfterHow Much Does Metal Roof Installation Cost in San Antonio?
Metal roof installation in San Antonio typically runs $9.50 to $18.50 per square foot, or roughly $16,000 to $32,000 for a standard 1,700-square-foot single-family home. That’s the all-in range for materials, labor, tear-off of the old roof, and the underlayment system. You’ll pay more for standing seam panels than for exposed-fastener corrugated metal, and San Antonio’s heat means the underlayment you choose matters more here than it would in, say, Minnesota.
Before you commit, know this: metal roofing is the fastest-growing segment in Bexar County’s residential market, and for good reason. A properly installed metal roof in this climate can outlast two asphalt shingle roofs. But the math only works if the install is done right, and that’s where the price difference between a low bid and a professional job becomes real money.
Metal Roof Installation Cost Breakdown (2026)
Here’s what our team at Mercer Roofing sees in San Antonio right now, broken into the line items that actually show up on an invoice:
| Line Item | Cost Range | Notes |
|---|---|---|
| Tear-off and disposal of existing roof | $2.00 – $3.50 per sq ft | Varies with number of layers and roof pitch |
| Decking repair/replacement | $1.50 – $4.00 per sq ft | Only where rot is found; often 10-20% of the deck in older Alamo Heights and Monte Vista homes |
| Underlayment (synthetic or high-temp rated) | $0.75 – $2.00 per sq ft | We recommend a high-temp synthetic underlayment for San Antonio’s attic heat |
| Corrugated/exposed-fastener metal panels | $4.50 – $7.50 per sq ft | Entry-level metal roofing; includes trim and screws |
| Standing seam metal panels | $8.00 – $13.00 per sq ft | Concealed fasteners; the premium option in Stone Oak and Dominion |
| Labor (install, trim, flashing) | $3.00 – $6.00 per sq ft | Higher for steep pitches and complex roof geometries |
| Flashing, drip edge, ridge caps, closure strips | $1.00 – $2.50 per sq ft | Often bundled into panel pricing by some contractors, itemized by others |
So for a 1,700-square-foot roof with standing seam panels, full tear-off, and standard decking in decent shape, you’re looking at $18,000 to $32,000. The same roof in exposed-fastener corrugated might come in between $13,500 and $21,000. Neither number includes gutters, skylights, or structural reinforcement, which some older San Antonio homes in areas like Jefferson and Tobin Hill may need when switching from a lighter asphalt shingle system.
What Affects Metal Roof Installation Pricing in San Antonio
- Roof pitch and geometry. The Spanish Colonial and Mediterranean-style homes common in Terrell Heights and Lavaca often have multiple roof planes, hips, and valleys. Each one adds cuts, flashing, and labor hours. A simple ranch in Oak Hills is faster and cheaper per square foot than a two-story with dormers.
- Panel type and gauge. Exposed-fastener panels in 29-gauge steel cost less than 24-gauge standing seam. Galvalume holds up well against San Antonio’s UV load, but we recommend a Kynar 500 (PVDF) coated panel for homes with full western exposure, especially in new developments west of 1604 where there’s little tree cover.
- Decking condition. Homes built before the 1980s in neighborhoods like Alta Vista often have 1×6 plank decking or plywood that’s seen decades of humidity cycles. If we have to replace decking, plan for $1,800 to $5,000 extra depending on how much is rotten or delaminated.
- Underlayment type. This is the part homeowners never see but regret skimping on. San Antonio’s July attic temps can exceed 140°F. A high-temp-rated synthetic underlayment adds $0.50 to $1.00 per square foot over basic felt and is one of the single best investments in the longevity of a metal roof here.
- Exposed vs. concealed fasteners. Standing seam uses hidden clips and factory-formed seams, which means two things: more material cost and more skilled labor. In the San Antonio market, expect standing seam to run $8 to $13 per square foot versus $4.50 to $7.50 for exposed-fastener panels.
- Removal of the existing roof. San Antonio allows one reroof layer over an existing shingle roof in some cases, but we do not recommend it with metal. The old shingles trap heat and moisture. Full tear-off adds $2.00 to $3.50 per square foot but is the only way the manufacturer’s warranty stays intact.
Metal Roof Cost by San Antonio Neighborhood
Prices shift across the metro because labor rates, roof styles, and home age vary. Here’s what we’re seeing in 2026:
- Alamo Heights / Terrell Hills: $18,000 – $36,000. These homes often have steep architectural roofs with multiple gables, cedar shake conversions, and strict city aesthetic guidelines that favor standing seam.
- Stone Oak / Sonterra: $17,000 – $33,000. Larger roof footprints (2,200-3,000 sq ft common) but simpler geometries on many late-90s and 2000s builds.
- Monte Vista / Olmos Park: $19,000 – $38,000. Historic districts with slate or tile overhangs demand custom flashing work. Some homes require structural consultation before metal goes on.
- Helotes / Grey Forest: $15,000 – $28,000. Hail-prone and often steeply pitched hill-country homes. Insurance commonly covers part of a metal re-roof here after a storm claim.
- Westover Hills / SeaWorld area: $14,000 – $26,000. Mostly production-built homes with straightforward ranch or two-story plans and lower labor costs due to volume.
Is a Metal Roof Worth It in San Antonio?
Short answer: yes, if you plan to stay in the home more than 8 to 10 years. Metal roofs in the San Antonio climate last 40 to 60 years versus 15 to 20 for architectural asphalt shingles. They reflect a significant amount of solar radiation, which directly cuts attic cooling load during summers that run from May through late September.
The math breaks down like this: a $22,000 standing seam roof on a San Antonio home over 50 years costs about $440 per year. An $11,000 asphalt shingle roof replaced three times over that same period, plus two tear-offs, lands closer to $40,000 to $45,000. That doesn’t include the energy savings, which our customers in Alamo Ranch and Cibolo routinely report as 10% to 15% on summer cooling bills after switching to a light-colored metal panel.
But here’s the honest caveat: a metal roof is only worth what the install quality allows. Exposed fasteners with rubber washers fail over time in our UV and thermal-cycling conditions. That’s why we recommend standing seam or high-quality exposed-fastener systems with stainless steel screws and neoprene washers rated for high-heat climates. The wrong fastener on a San Antonio roof is a leak waiting for August.
Metal vs. Asphalt Shingle Costs
For context, architectural asphalt shingle installation in San Antonio runs $4.50 to $7.00 per square foot, or about $7,500 to $12,000 for that same 1,700-square-foot roof with tear-off. Metal is roughly double up front, sometimes 2.5 times for standing seam. The long-term value proposition is the lifespan and energy performance, not the initial outlay.
One thing often overlooked in the comparison: insurance. Several major insurers now offer premium discounts of 5% to 15% for metal roofs rated for Class 4 hail impact, which matters in San Antonio’s hail alley along the I-10 corridor. If your home is in the Stone Oak or Timberwood Park area, ask your agent about the UL 2218 Class 4 rating before selecting panels.
How to Save on Metal Roof Installation
- Get three written quotes, and compare line items, not totals. One bid may include underlayment and flashing where another adds them later. A written price before work starts is the standard you should hold every contractor to.
- Ask about off-season timing. San Antonio roofers are busiest in spring and fall. Scheduling a December or January install can sometimes save 5% to 8%, though weather windows are tighter.
- Consider exposed-fastener panels for detached structures. A workshop, barn, or carport doesn’t need standing seam. Use corrugated metal at $4.50 to $7.50 per square foot and save the premium panels for the main house.
- Don’t skip the tear-off. Laying metal over old shingles saves $2.00 to $3.50 per square foot up front, but it shortens the life of the new roof and voids most manufacturer warranties. The cheapest way to pay for a roof is once.
- Look at steel, not aluminum. In San Antonio, aluminum panels cost 15% to 25% more and offer no meaningful corrosion advantage unless you live within a few miles of the coast. Galvalume steel is the standard here.

What Our Customers Ask Before Signing
Metal roofing is a big enough investment that most San Antonio homeowners have real questions before they’re comfortable. Here are the ones we hear most often, answered with the numbers we quote in 2026.
Do you offer manufacturer warranties?
Yes. Every metal roof we install is backed by the panel manufacturer’s finish warranty, typically 25 to 40 years for Kynar 500 coated steel. What’s more important is our 365-Day Done Right Promise: if the work is not right within a year, Mercer makes it right. That’s in writing, included with every metal roof installation, and no San Antonio contractor can offer that and not mean it.
Who exactly will be on my property?
You’ll know before they arrive. Mercer Roofing sends every technician’s name and photo ahead of the visit. They arrive in a clean, marked uniform with a photo ID badge at the door. Every technician is background-checked and identity-verified under the Threshold Verified standard, which each independently owned Mercer location is contractually held to. When a crew is on your roof for two to five days for a metal install, that matters.
FAQs – Metal Roof Installation Cost in San Antonio
How much does a metal roof cost for a 2,000 square foot home in San Antonio?
A 2,000-square-foot home in San Antonio with standing seam metal runs $19,000 to $34,000 installed. Exposed-fastener corrugated metal on the same footprint runs $14,000 to $22,000. The spread depends on tear-off needs, decking repair, and roof pitch. For a precise number from a written estimate, call (254) 276-4369.
Is it cheaper to install metal roofing or replace with shingles in San Antonio?
Shingles are cheaper up front: $4.50 to $7.00 per square foot versus $9.50 to $18.50 for metal. But per year of expected service life in the San Antonio climate, metal runs $350 to $550 per year versus $550 to $750 per year for asphalt shingles when you account for two or three replacement cycles.
Does a metal roof lower homeowners insurance in Texas?
Often yes, if the panels carry a Class 4 UL 2218 impact rating. Many insurers in Bexar County offer discounts of 5% to 15% on wind and hail premiums. Confirm with your carrier before selecting a panel. We can spec any metal roof to Class 4 at no additional material cost in most cases.
How long does metal roof installation take in San Antonio?
For a standard single-family home, expect 2 to 5 days depending on roof size, pitch, and the amount of decking repair needed. Standing seam takes longer than exposed-fastener panels because every seam is field-formed. We tell you the schedule in writing before the first panel goes on, and you’ll know exactly who’s arriving each morning.
Can I get metal roof financing in San Antonio?
Many homeowners use HELOCs or cash-out refinancing for metal roofing, but Mercer Roofing can also connect you with third-party financing partners offering terms from 5 to 15 years with rates typically between 6% and 12% APR depending on credit. Monthly payments on a $25,000 roof often land between $230 and $420.
Is metal roofing louder during San Antonio thunderstorms?
No, not when installed over proper decking and underlayment. A metal roof installed over solid decking with a quality synthetic underlayment is only marginally louder than shingles, around 2 to 4 decibels during hard rain. The myth comes from metal roofs over open-frame structures like barns and patios, which do amplify sound.
