Commercial Metal Roofing in San Antonio and Austin, TX

Take FM 1825, US 290 East or SH 130 out of town sometime and count the metal roofs. You'll lose track fast. Pre-engineered shops, flex warehouses, equipment barns and rows of self-storage went up across the Austin metro, and nearly all of them are roofed in metal. Our commercial metal roofing work is what keeps them dry. That means swapping out dented or rusted panels, tightening the fasteners that hold the whole thing down, fixing trim and gutters, and putting on a new roof once the old one is used up. Many of these buildings have a few decades on them by now. The original screws and sealant almost never last that long.

A house is a different animal. On a home metal roof, like the ones on our metal roofing page, people mostly ask how it'll look and how long it'll go. Commercial owners ask other things. How many squares? What pitch? And what business is still running under the crew? Picture a cabinet shop in Pflugerville: sawdust and rain can't land on the same bench. A church hall in Georgetown has to be closed up before Sunday.

We think owners replace most commercial metal roofs years too early. The panels are usually fine. It's the screws, washers and trim that gave out, and a proper fastener program can add real service life for a fraction of what a new roof costs. When that's your situation, we'll say so. And when the roof really is done, you'll hear that just as plainly.

Climb onto almost any commercial metal roof in Central Texas and you'll find one of two kinds.

Exposed-fastener panels (R-panel, PBR and other ribbed sheets) are screwed straight through the face into the purlins. They go up quickly and cost less on day one. Their weak spot is the screw itself. Each one has a rubber washer, and a big shop roof might carry thousands. Our heat makes the steel expand and shrink every single day, and over the years that backs screws out and bakes the washers dry.

Standing seam panels keep their clips tucked under raised seams, so nothing punctures the weather surface. On a low-slope warehouse you want the mechanically seamed kind. It sheds water at pitches where a ribbed sheet lets it creep back up through the laps.

Pitch matters more than most owners expect. Every panel maker publishes a minimum slope for each profile, and if a roof goes on below that number, the end laps leak. No amount of sealant changes it. That's why we measure slope on every building before we suggest a panel, and why patching an old roof that was built too flat for its profile is money spent on the wrong repair. You see it a lot on lean-tos and porch roofs some previous owner bolted to the side of a shop, where the pitch fades out to nearly nothing. Another bucket of mastic won't help. A different panel will, or a section of membrane tied into the metal.

Once we're up there, a commercial metal roof usually lands in one of four buckets.

• Spot repair. A few dented or rusted panels, maybe a torn ridge closure or a gutter seam that split. New panels go in at the same profile and gauge, and the laps get resealed.
• Re-screw program. The leaks are scattered across the field, from screws that backed out and washers that died, but the panels have life left. Every fastener comes out and an oversized screw with a fresh washer goes in.
• Retrofit. Old panels rusting through on a sound frame. We set new metal over the top on a spacer or sub-purlin system, and the gap often gets insulation. Tenants can usually keep working below.
• Full replacement. Rusted purlins, soaked insulation, or a roof that was built below its slope rating. The old system comes off and our crew rebuilds in sections, so the building never sits open overnight.

Got a flat section or a shingled office wing too? Same crew. The low-slope parts fall under our flat roofing scope, and a full tear-off on a mixed building runs through our commercial roof replacement process.

Metal holds up to Central Texas weather pretty well. It isn't storm proof, though. On September 24, 2023, hail as big as 4 inches came down on Round Rock and north Austin, and on a metal shop hail that size dents panels, cracks skylight sheets and chips the paint, and then the dents hold water. Wind does different damage. The May 28, 2025 microburst, gusting to 77 mph at the airport, cut a path from Hyde Park east past ABIA, and wind like that peels off trim and ridge caps and lifts any panel whose screws had already worked loose. Before you assume you're covered, read the policy. Some commercial policies call dented metal cosmetic and won't pay a dime. Our team has 30+ years of insurance claim experience, and former insurance adjusters are on our staff. We document the damage one panel at a time, meet the carrier's adjuster up on the roof and show what the storm did. All six steps are laid out on our insurance claims page. Roof open right now?
