A complete breakdown of metal roof replacement costs for San Antonio homeowners in 2026, including material types, labor, tear-off, and what drives prices up or down in Bexar County.
If you are a San Antonio homeowner thinking about switching from asphalt shingles to metal, the first number you need is an honest, local cost figure, not a national average that does not reflect Bexar County labor rates, Texas permit requirements, or the specific demands of our climate. The short answer for 2026 is that a full metal roof replacement in San Antonio typically runs between $26,000 and $45,000 for a standard 2,000 square foot home, depending on the metal type, panel system, and the complexity of your roof.
That range is wide because "metal roof" is not one product. Corrugated panels, standing seam systems, and stone-coated steel tiles all carry different price tags and different performance profiles. This guide breaks down every cost factor, explains what drives prices higher or lower, and tells you exactly what to expect from a San Antonio metal roofing contractor at each price point.
Roofing contractors price jobs by the "square," which equals 100 square feet of installed roof surface. Your roof surface is almost always larger than your home's footprint because of pitch and overhang. A 2,000 square foot home typically has between 2,200 and 2,600 square feet of actual roof surface. When you see a per-square price on a quote, multiply it by the number of squares on your roof to get the base material and labor cost before adding tear-off, permits, and accessories. In San Antonio in 2026, metal roofing runs approximately $600 to $900 per square installed, depending on the system you choose.
The type of metal and the panel system you choose is the single largest variable in your total project cost. In San Antonio, the most commonly installed systems are corrugated steel panels, standing seam steel panels, and stone-coated steel shingles. Each serves a different budget, aesthetic preference, and performance requirement.
Corrugated metal panels are the most affordable option. They use exposed fasteners, install quickly, and are well suited to agricultural buildings, workshops, and budget-conscious homeowners who prioritize durability over appearance. In San Antonio, corrugated steel runs approximately $3.50 to $8.00 per square foot installed.
Standing seam panels use hidden fasteners and interlocking raised seams that run vertically up the roof. They are the premium residential choice because they shed water more effectively, handle thermal expansion without fastener stress, and carry better manufacturer warranties. Expect to pay $10 to $16 per square foot installed in San Antonio.
Stone-coated steel mimics the look of shingles, slate, or tile while delivering the durability of steel. It is heavier than bare steel panels and slightly more complex to install. San Antonio pricing runs $12 to $18 per square foot installed.
- Panel system confirmed: exposed fastener (corrugated) vs. hidden fastener (standing seam)
- Steel gauge specified in writing: 26-gauge or thicker is recommended for San Antonio hail exposure
- Paint system specified: PVDF (Kynar) finish lasts longer under Texas UV than polyester coatings
- Color selected from manufacturer's standard range custom colors add cost and lead time
- Warranty term confirmed: both manufacturer product warranty and contractor workmanship warranty
Your roof's actual square footage is almost always larger than your home's interior footprint. A 2,000 square foot single-story home typically has a roof surface between 2,200 and 2,800 square feet, depending on the pitch. Steeper pitches cover more surface area per linear foot of home and require more material. They also take longer and cost more to install safely, as crews need additional safety equipment and work more slowly on steep slopes.
Roof complexity matters just as much as size. Simple gable roofs with two slopes are the fastest and cheapest to install. Roofs with dormers, multiple valleys, hips, skylights, chimneys, HVAC curbs, or other penetrations require significantly more cutting, flashing, and precision work. In San Antonio, a complex roof with multiple planes can add 15 to 30 percent to the base price of a standing seam installation.
| Home size (sq ft) | Estimated roof surface | Corrugated steel (est. total) | Standing seam (est. total) |
|---|---|---|---|
| 1,000 sq ft home | 1,100 to 1,300 sq ft | $7,700 to $10,400 | $11,000 to $20,800 |
| 1,500 sq ft home | 1,650 to 2,000 sq ft | $11,550 to $16,000 | $16,500 to $32,000 |
| 2,000 sq ft home | 2,200 to 2,600 sq ft | $15,400 to $20,800 | $22,000 to $41,600 |
| 2,500 sq ft home | 2,750 to 3,200 sq ft | $19,250 to $25,600 | $27,500 to $51,200 |
| 3,000 sq ft home | 3,300 to 4,000 sq ft | $23,100 to $32,000 | $33,000 to $64,000 |
Estimates based on San Antonio 2026 market rates of $7 to $8 per sq ft for corrugated and $10 to $16 per sq ft for standing seam. Actual quotes vary by roof complexity, pitch, and selected accessories.
Never estimate your roof size from the inside square footage of your home. Always ask the contractor to measure the actual roof surface and provide the square count on the written estimate. A discrepancy between the estimated square count and the actual measurement is one of the most common sources of price surprises after a metal roof replacement project gets underway in San Antonio.
- Contractor provides a measured square count of actual roof surface on the written estimate
- Pitch (slope) of the roof identified and any steep-pitch labor premium disclosed upfront
- Number of valleys, hips, and roof planes counted each adds cutting, flashing, and labor time
- All penetrations inventoried: skylights, chimneys, vents, HVAC units, and pipe boots
- Custom flashing requirements for any non-standard penetrations quoted as a separate line item
A full metal roof replacement in San Antonio almost always requires tearing off the existing roof system before new metal panels go on. Texas building codes generally limit roofs to two total layers of material. If your existing roof is a second layer or if you are upgrading from asphalt shingles to metal, the tear-off is required. This is a real line item in your project cost, and it needs to be quoted separately from the material and installation price.
Tear-off and disposal typically costs $1.00 to $3.00 per square foot in San Antonio. For a 2,000 square foot home, that is $2,200 to $5,800 just for removal and haul-off. The price varies based on the number of existing layers, the weight of the existing material, and dumpster or hauling fees in Bexar County.
Decking inspection and repair is the hidden wildcard in any roof replacement. Once the old shingles come off, the contractor can see the plywood or OSB sheathing underneath. Soft spots, rot, or water-damaged sections must be replaced before metal panels go on. Decking replacement runs $6 to $20 per square foot depending on the board size and extent of the damage.
Underlayment is a critical component of a properly installed metal roof and should always be included in your quote. Standard synthetic underlayment runs about $1.15 to $1.20 per square foot. For standing seam installations on San Antonio homes, a high-temperature underlayment is strongly recommended because metal panel surfaces can reach 160 to 180 degrees Fahrenheit in summer. High-temp underlayment runs about $1.30 per square foot and is worth the additional cost in the Texas heat.
- Tear-off and disposal included as a separate line item on the written estimate
- Number of existing shingle layers documented before the quote is submitted
- Underlayment type specified: synthetic standard vs. high-temp for standing seam applications
- Decking contingency discussed: what is the per-sheet price if damaged sections are found?
- Bexar County roofing permit included in the quote and pulled by the contractor
- Disposal method confirmed: licensed haul-off, not burned or buried on property
Metal roofing installation is a skilled trade. Standing seam panels in particular require fabrication equipment, precision seaming tools, and experience with the specific panel system being installed. A crew that installs asphalt shingles five days a week and occasionally installs metal is not the same as a dedicated metal roofing crew. The difference shows up in the quality of the seams, the condition of the flashings, and whether the roof holds up to San Antonio's next hailstorm.
In San Antonio in 2026, roofing labor runs approximately $3.50 to $8.00 per square foot for metal installation, on top of material costs. Labor rates are higher for standing seam than for corrugated panels because the installation process is more specialized. For a 2,500 square foot roof, labor alone could run $8,750 to $20,000 depending on the panel system chosen.
Ask every contractor for their specific metal roofing experience before accepting a quote. A legitimate metal roofing crew in San Antonio can tell you how many standing seam or stone-coated steel roofs they installed in the last 12 months, which manufacturers they are certified with, and what seaming equipment they own. Contractors who do not own their own seaming machine and rent or borrow equipment are a yellow flag on standing seam jobs. Ask to see photos from recent metal roof installations they completed locally.
- Contractor demonstrates recent metal roofing experience specific to the panel type being installed
- Standing seam contractor owns or leases a dedicated seaming machine for the panel profile selected
- Flashing scope confirmed: chimney, vent, valley, and eave flashing included in the base quote
- Ridge cap installation method specified: closure foam, ridge vent, or solid ridge panel
- Crew size and timeline provided: how many installers and how many calendar days to complete?
- Subcontractor use disclosed: will the crew doing the work be the contractor's own employees or a sub?
Once you add material, labor, tear-off, underlayment, permits, and decking contingency, the total cost for a metal roof replacement in San Antonio in 2026 comes together quickly. The table below shows all-in estimated totals for the most common scenarios we quote in the Bexar County market. These are realistic numbers, not lowball figures designed to get you through the door and then change-ordered up.
| Scenario | Home size | System | Total estimated cost (San Antonio, 2026) |
|---|---|---|---|
| Budget metal replacement | 1,500 sq ft | Corrugated galvanized steel | $13,000 to $19,000 |
| Standard residential replacement | 2,000 sq ft | Standing seam, 26-gauge | $26,000 to $38,000 |
| Premium residential replacement | 2,000 sq ft | Stone-coated steel shingles | $28,000 to $42,000 |
| Large home standard | 2,500 sq ft | Standing seam, 26-gauge | $32,000 to $48,000 |
| Complex roof (dormers, hips) | 2,000 sq ft | Standing seam | $33,000 to $45,000 |
| Insurance storm claim replacement | Any size | Matches existing or upgrades | Out-of-pocket: deductible only (if claim approved) |
1. File an insurance claim if storm damage is present. If your existing roof has hail or wind damage from a qualifying storm event, your Texas homeowners insurance policy may cover all or most of the replacement cost. You are responsible for your deductible (typically $1,000 to $2,500), but the insurance company covers the rest. You have up to one year from the storm date to file a claim in Texas. Get a professional inspection and document the damage before filing.
2. Apply for the federal energy efficiency tax credit. As discussed in our pillar guide, qualifying metal roofs with ENERGY STAR certified cool-roof coatings may be eligible for a federal tax credit of up to 30 percent of the project cost under current IRS guidelines. Confirm eligibility with your tax professional before assuming the credit applies.
3. Schedule your replacement in fall or winter. Roofing demand in San Antonio peaks from March through September. Scheduling your metal roof replacement in October through February can save 10 to 20 percent on labor because contractors have more availability and are more likely to negotiate on price during slower months.
4. Choose a steel gauge that matches your actual exposure risk. 26-gauge steel is the sweet spot for most San Antonio homes. Going down to 29-gauge saves money upfront but sacrifices hail resistance and surface life significantly. Going up to 24-gauge steel on a simple gable roof that is not in an especially hail-prone micro-zone is often overkill. A good contractor will recommend the right gauge for your specific location and roof profile without upselling you.
- Roof inspected for storm damage before ruling out an insurance claim
- Tax credit eligibility verified: ENERGY STAR qualified cool-roof coating on specified panel
- Off-season scheduling explored: October through February bookings often command better pricing
- Steel gauge matched to actual exposure: 26-gauge is the right call for most San Antonio roofs
- Financing options requested from the contractor if total project cost needs to be spread over time
- Three written quotes obtained before signing any agreement
