If you're pricing a metal roof, you've probably noticed something frustrating: almost no roofing company will tell you what it costs until someone is standing in your driveway.

We understand why. Every roof is different, and nobody wants to quote a number and then have to explain why the real price is higher. But you deserve to know whether a metal roof is even in your budget before you spend an afternoon with a salesperson. So this article gives you real numbers: what homeowners in San Antonio, Corpus Christi, Rio Grande Valley, and the Texas Hill Country typically pay, what pushes that number up or down, and how to tell whether a quote is fair.

We'll also be honest about who a metal roof is not a good fit for.

The short answer

For a typical San Antonio home, a professionally installed residential metal roof usually costs about $20,000 to $40,000 on a typical 2,500 sq ft roof. Larger homes, complex rooflines, and premium materials can go well beyond that.

For context, other San Antonio roofers' published 2026 pricing for standing seam generally falls between about $8.40 and $17 per sq ft installed, or roughly $18,000 to $38,000 for a smaller home.

At AL-CO, most of our San Antonio residential projects land at $8–$16 per sq ft installed. Our typical residential roof is about 2,500 sq ft, which works out to about $20,000–$30,000 for standing seam and $32,500–$40,000 for metal shingles or shake.

Rule of thumb: Metal typically costs about two times the price of an asphalt shingle roof, and up.

All prices in this guide are per square foot of roof surface, which is larger than your home's floor area. Once you count pitch and overhangs, the roofs we install are typically about 2,500 sq ft. (You may see some roofers quote by the "square," which just means 100 sq ft of roof.)

Why is the range so wide? Because "metal roof" covers everything from thin exposed-fastener panels on a barn to a heavy-gauge standing seam or stone-look metal shingle roof built to last 50 years. The rest of this article walks through what actually moves the price.

The 6 factors that drive the cost of a metal roof

1. The type of metal roof system

This is the biggest factor. On homes in our area, you'll mostly see three styles:

Standing seam: Long vertical panels with concealed fasteners and raised seams. Clean, modern, or farmhouse look. Industry ranges in San Antonio run roughly $9–$17 per sq ft installed. AL-CO standing seam: $8–$12 per sq ft installed (about $20,000–$30,000 on a typical 2,500 sq ft roof).

Metal shingles and shakes (like the Country Manor Shake profile we install): Interlocking metal shaped to look like wood shake, slate, or traditional shingles. They're popular in neighborhoods and HOAs that want a traditional look. AL-CO metal shingles and shake, such as Country Manor Shake: $13–$16 per sq ft installed (about $32,500–$40,000 on a typical 2,500 sq ft roof).

Stone-coated steel: Steel with a granular finish that looks like tile or shake. Other San Antonio roofers' published pricing puts it at about $9–$14 per sq ft.

You'll also see exposed-fastener (screw-down) panels quoted for $5–$9 per sq ft. They have a place on barns and outbuildings, but the exposed screws and washers need maintenance over time. That's why we don't recommend them for most homes, and it's a common reason one "metal roof" quote is half the price of another.

2. Metal, gauge, and paint finish

Two roofs can look alike from the street and still be very different products. The metal, its thickness, and the paint on it all affect both the price and how long the roof looks and performs like new.

The metal itself. Most homes in our area get Galvalume steel, which is steel coated with an aluminum-zinc alloy that resists rust. It's strong, proven, and the best value for most homeowners. Aluminum costs more but won't rust, which makes it a good fit near the coast, including Corpus Christi and the Rio Grande Valley. Copper and zinc are luxury metals that develop a natural patina. They cost several times more than steel, which can push a project well above our typical range.

Gauge (thickness). With metal, a lower gauge number means thicker metal. 24-gauge steel is thicker, stiffer, and more dent-resistant than 26 or 29 gauge, and it costs more. Thicker panels also lie flatter, which helps reduce oil-canning (visible waves in the flat parts of panels). In hail country, that extra thickness is worth asking about.

Paint finish. A Kynar 500 / PVDF paint system holds its color and resists fading and chalking far longer than the cheaper SMP (silicone-modified polyester) paints used on many budget roofs. Under South Texas sun, an SMP roof can noticeably fade and chalk while a PVDF roof still looks close to new. PVDF finishes also typically carry longer finish warranties.

Why it matters here. Between summer heat, intense UV, and spring hail, San Antonio is hard on roofs. A thinner panel with a budget paint can save money on day one, but it's more likely to dent, fade, and look tired years sooner. When you compare quotes, ask for the metal type, gauge, and paint system in writing.

3. Roof size

Bigger roof, more material and labor. But price per square foot often drops slightly on larger, simpler roofs, because setup and staging costs get spread over more area.

Keep in mind that your roof's area isn't the same as your home's living square footage. The roof covers your home's footprint, plus extra area from the roof's pitch and the overhangs past the walls.

That's why a two-story home usually has a smaller roof area compared to its living square footage than a one-story home of the same size. A 3,000 sq ft one-story home spreads all that living space under one roof, while a 3,000 sq ft two-story home stacks half of it on top of the other half, so its roof only has to cover about half the footprint. (Two-story roofs do cost more per square foot to work on because of the height, which we cover below.)

4. Your roof's shape, pitch, height, and access

How steep, tall, and complicated your roof is, and how easy it is to get to, can move the price a lot. Two homes with the same square footage can differ by $10,000 or more because of these factors alone. We cover these in detail below, in What makes a metal roof cost more?

5. What's under the old roof

Most projects include tearing off the existing roof. Once it's off, any rotted or damaged decking has to be replaced before metal goes on. Underlayment matters too: a high-temperature synthetic underlayment costs more than basic felt and performs much better under metal in Texas heat. At AL-CO, the first 100 sq ft of decking replacement is included at no additional cost. We see damaged decking so often that we plan for it, so we don't have to change your price on the first day of work. If your roof needs more than that, it's quoted up front in your estimate.

6. Local requirements, permits, and the market

Permits, HOA rules, historic-district requirements (King William, Monte Vista), and wind or hail ratings all affect what can be installed. Steel and aluminum prices have also risen with tariffs in 2025–2026, so quotes from a few years ago aren't a good benchmark.

What makes a metal roof cost more?

If your quote is toward the top of our range, or above it, one or more of these is usually the reason.

Exotic metals and premium finishes. Most homes use Galvalume steel. Aluminum, zinc, and copper cost much more per pound and take more skill to form and install, so they can push a project well above steel pricing. Premium paint systems, special-order colors, and specialty finishes like textured or metallic coatings also cost more than standard colors and often come in smaller, special production runs.

Steep roofs. On a steep roof, installers can't simply walk the surface. They need harnesses, anchors, roof jacks, and toe boards, and every panel or shingle takes longer to place safely. Slower work means more labor hours.

Tall roofs and multi-story homes. A two- or three-story roof means getting materials and people higher off the ground. That often calls for scaffolding or staging, lifts, and more fall protection, plus extra time hauling material up and debris down.

Complex roof shapes. A simple roof with a few big, flat planes goes fast. Every valley, hip, dormer, turret, skylight, and chimney means more cutting, more custom-bent trim and flashing, and more detail work to keep it watertight. Those details are where a roof is most likely to leak, so they're where we take the most time.

Difficult access. If we can't pull a truck or trailer close to the house, everything takes longer. Tight lots, no driveway access, landscaping we have to protect, long carry distances, and limited space to stage materials all add labor. Some Hill Country properties also have long or steep drives that make material delivery harder.

None of these are reasons to skip a metal roof. They're just the honest reasons one home costs more than another. A good estimate should show you which ones apply to your home.

What can lower the price

A simpler profile or a standard color instead of a special-order one.

A roof with fewer penetrations and valleys.

Timing your project outside peak post-storm demand.

Possible insurance discounts for Class 4 impact-rated roofing. Ask your insurance agent, since discounts vary by carrier.

Choosing metal shingles or shake and installing over your existing roof. On our metal shingle and shake programs, like Country Manor Shake, we can often install over one layer of existing shingles. That saves you the cost of tearing off and hauling away the old roof. Published San Antonio pricing puts overlay savings of about $1–$2.50 per sq ft. This option doesn't apply to standing seam, as explained next.

How AL-CO handles tear-off vs. installing over your old roof

Standing seam is always a full tear-off. Standing seam panels need a smooth, flat deck underneath. Installing them over old shingles can cause oil-canning, which shows up as visible waves in the flat parts of the panels. Tearing off the old roof gives us the smooth surface that keeps your panels looking flat and clean.

Metal shingles and shake can often go over one layer of existing shingles. Their shape and interlocking design handle an overlay well, so you save on tear-off and disposal.

We never rely on your old roof to keep water out. When we install over existing shingles, we install the new metal roof as a complete, watertight system, exactly as if the old roof didn't exist. The old shingles are not part of your leak protection.

Decking is planned for on tear-offs. When we tear off, the first 100 sq ft of decking replacement is included at no additional cost. We see damaged decking so often that we plan for it, so your price doesn't change on the first day of work. Anything beyond that is quoted up front in your estimate.

Metal vs. asphalt shingles

Metal typically costs about two times the price of an asphalt shingle roof, and up. That's the honest rule of thumb we give every homeowner. The difference is that a quality metal roof is built to last decades longer than shingles in San Antonio's heat and hail.

We'll cover the full life-cycle cost of metal vs. asphalt in an upcoming article.

Why metal roof quotes vary so much

It's normal for San Antonio homeowners to get metal roof quotes that are $10,000 or more apart. Usually the difference is in things you can't see from the ground:

Panel gauge and paint system (26 vs. 24 gauge, SMP vs. PVDF)

Exposed-fastener vs. concealed-fastener systems

Underlayment quality

Trim and flashing custom-bent to fit your roof or one-size-fits-all

What's included: tear-off, decking, permits, and cleanup, or added later

Installer training and workmanship warranty

We've written about how corners get cut on standing seam roofs. When you compare quotes, ask each roofer to list these items in writing.

Is AL-CO the cheapest metal roofing company in San Antonio?

No, and we don't try to be. If the lowest price is your top priority, there will almost always be someone who can beat our number.

What you get for our price: we're a metal-roofing-only contractor, so metal is all we do. Our crews are factory-trained on the systems we install, and your roof comes with the full manufacturer's warranty. We also include the first 100 sq ft of decking replacement, so your price doesn't change on day one. We'd rather explain our price once than have you deal with a leak in five years.

Who a metal roof is NOT right for

A metal roof is a long-term investment, and it isn't the right choice for everyone. We'd rather tell you now than sell you something that doesn't fit. Here's who we'd steer toward another option:

You plan to sell in the next few years. A metal roof's biggest payoff comes over decades. If you just need a sound roof for closing, a quality shingle roof may make more financial sense, since you may not get all of the extra cost back in the sale price.

Your budget can't stretch to about two times the price of shingles. Metal typically costs about two times as much as asphalt, and up. If that would strain your finances, a good shingle roof now is better than a stressful metal roof.

You want the lowest possible upfront price. If price is the only thing that matters, metal, and especially a full-service metal-only contractor like us, probably isn't your best fit. That's okay.

Your HOA or historic district doesn't allow it. Some neighborhoods restrict metal roofs or certain looks. Metal shingles that look like shake or slate are sometimes approved where panels aren't, so it's worth checking your rules before you fall in love with a style.

Your roof is very low-slope or flat. Most residential metal shingles need a certain pitch to shed water, and very low slopes may need a different system, like a membrane roof or a specialty low-slope panel. We'll tell you if your roof falls into that category.

Your home has structural or deck problems you aren't ready to fix. A metal roof is only as good as what it's attached to. If the framing or decking needs major repair and that can't be addressed, it's better to fix that first than to put a 50-year roof on a weak base.

You simply don't like the look. Metal roofs come in many styles, but some homeowners just prefer the look of shingles or tile. You'll live with your roof every day, so it should be one you like.

It's a short-term rental or a flip. If you're holding a property only briefly, or mainly need the lowest cost per unit, the long life of metal may not pay off for you the way it does for a long-term homeowner.

How to get an accurate price for your home

The ranges above will tell you whether a metal roof is realistic for your budget. The only way to get your exact number is to measure your roof and look at what's under it.
