Commercial Roof Installation in Austin — The Install Decides the Lifespan
Two crews can install the exact same membrane and get a 10-year gap in how long it lasts. The difference is the install. We install TPO, EPDM, PVC, built-up, and metal to manufacturer spec — fastened, adhered, or welded correctly the first time, and backed by a real warranty.
Commercial roof installation in Austin is the installation of a new roof system on a commercial building — new construction or a replacement — including the attachment method (mechanically fastened, fully adhered, or ballasted), the membrane or metal, and all flashing and detailing. It sounds simple, but the install is exactly where roofs succeed or fail: correct fastening patterns, proper seam welds, and manufacturer-spec detailing are what separate a roof that hits 30 years from one that leaks in year two.
ATX Commercial Roofing Pros is an Austin commercial roof installation company that installs every major system to manufacturer specification. As a certified installer for GAF, Firestone, and Carlisle, our installs qualify for full manufacturer system warranties. We've installed and serviced 500+ commercial roofs across the metro since 2008 — $2M insured, OSHA-compliant, zero accidents in 2024.
The membrane is a commodity. The installation isn't.
You can buy the same TPO or PVC from the same manufacturer as every other roofer in town. What you can't buy off a shelf is a correct install — and roofing manufacturers know it, which is why the strongest warranties are only available through certified installers. Here's where installs actually go wrong, and what a correct one gets right:
Fastening pattern & density. Too few fasteners (or wrong placement) and the roof fails wind-uplift and can peel in a storm. We install to the engineered pattern for your building's wind zone.
Seam welds. Cold or over-welded seams are the #1 single-ply install failure. We probe every heat-welded seam so the bond is continuous and void-free.
Flashing & penetrations. Most leaks start at curbs, drains, and parapets. Correct, manufacturer-detailed flashing is where a good install earns its keep.
Substrate prep. Installing over a wet, dirty, or uneven substrate dooms the membrane. We confirm the deck and insulation are sound and dry first.
How we attach the roof — matched to your building
Single-ply roofs are attached one of a few ways, and the right choice depends on the deck, wind exposure, and whether the building can tolerate fasteners penetrating the deck. A good commercial roof installation company in Austin picks the method for the building — not habit.
| Method | How it works | Best for |
|---|---|---|
| Mechanically fastened | Membrane fastened to the deck with plates/screws along seams | Most cost-effective; strong wind performance; common on metal/wood decks |
| Fully adhered | Membrane bonded to substrate with adhesive across the whole field | Smooth appearance, high wind uplift, no flutter; exposed or high-visibility roofs |
| Ballasted | Loose-laid membrane held by stone or pavers | Large simple roofs where weight is acceptable and cost matters |
| Induction-welded | Plates fastened to deck, membrane welded to plates (no field penetrations) | High wind uplift without seam-line fastening; premium single-ply |
| Heat-welded seams | TPO/PVC seams fused with hot air into a monolithic sheet | Every single-ply install — the seam is only as good as the weld |
We recommend the attachment method during the quote and explain the trade-offs — cost, wind rating, and roof life — so it's an informed choice.
Every major commercial roof system
Because we install all of them, the recommendation fits your building rather than the one product we carry. Certified installer for GAF, Firestone, and Carlisle.
TPO
Energy-efficient white single-ply, heat-welded seams. The go-to for budget-conscious, code-friendly installs.
EPDM
Durable rubber membrane for large, simple roof planes — decades of field track record.
PVC
Best for restaurants and grease/chemical exposure; strong weldability and puncture resistance.
Built-up (BUR)
Multi-ply "tar and gravel" systems for heavy traffic and layered protection.
Modified bitumen
Torch- or cold-applied cap sheets; easy future field repairs on mixed-use buildings.
Metal (standing seam)
40+ year sloped-roof systems with concealed fasteners and engineered edge metal.
Our commercial roof installation process
Assessment & system spec
We evaluate the building (or plans), recommend the right system and attachment method, and return a detailed, line-item install quote with the trade-offs spelled out.
Substrate prep
We confirm the deck and insulation are sound, dry, and clean — and correct anything that would compromise the new membrane before it goes down.
Spec-correct installation
OSHA-compliant crews install to the manufacturer's fastening pattern and detailing, welding and probing seams as we go so nothing gets buried out of spec.
Inspection & warranty registration
Final (and manufacturer, where required) inspection, water-testing as needed, then documentation and full system-warranty registration.
Replacing an old roof rather than building new? The install is the same craft either way. For the full deck-up build, see commercial roof construction; to protect the new roof once it's on, see roof maintenance.

Commercial roof installation in Austin — FAQ
How long does a commercial roof installation take?
It depends on roof size, system, and access, but most single-ply installs on a typical commercial building run a few days to a couple of weeks. We give you a firm timeline in the quote and sequence work to keep the building protected and, on occupied buildings, operating throughout.
Which attachment method is best — fastened, adhered, or ballasted?
It depends on the deck type, wind exposure, and whether deck penetrations are acceptable. Mechanically fastened is the most cost-effective and performs well in wind; fully adhered gives the smoothest look and highest uplift; induction-welded avoids seam-line penetrations; ballasted suits large simple roofs where weight is fine. We recommend the method for your building and explain the trade-offs.
What roof systems do you install?
All major commercial systems — TPO, EPDM, and PVC single-ply; built-up (BUR) and modified bitumen; and standing-seam and exposed-fastener metal. As a certified installer for GAF, Firestone, and Carlisle, we install to manufacturer spec so the roof qualifies for a full system warranty. See our commercial roofing overview.
Does the installer really affect how long the roof lasts?
More than almost anything else. Fastening pattern, seam welds, substrate prep, and flashing detail decide whether a roof reaches its rated life or fails early — and a poor install can void the manufacturer warranty entirely. That's why choosing a certified Austin commercial roof installation company matters as much as choosing the membrane.
Do your installations come with a warranty?
Yes. Because we install to GAF, Firestone, and Carlisle system details as certified installers, new roofs are eligible for full manufacturer system warranties covering both material and workmanship, on top of our own workmanship warranty.
Are you licensed and insured?
We carry $2M in liability coverage, are fully insured, and run OSHA-compliant crews with a zero-accident 2024 record. Texas does not issue a statewide roofing contractor license, so the right way to vet any installer here is by insurance certificates and manufacturer certifications — both of which we provide on request.
What areas do you install in?
Austin and the surrounding metro — Round Rock, Cedar Park, Pflugerville, Georgetown, Leander, Kyle, and Buda — for new installs, replacements, and multi-building developments.
