Austin has a commercial roofing requirement that almost nowhere else in Texas does, and it catches out-of-town contractors constantly. Under the City's amended energy code, a commercial roof surface with an incline greater than 2:12 must use a material with a minimum solar reflectance of 0.35 or a minimum initial SRI of 29. The model IECC does not require that. Dallas does not require that. Austin does — and the specification has to account for it before anyone orders material.
Roof Experts is the commercial roofing partner Austin TX property owners trust. We bring DFW-quality crews and materials to every Austin project — TPO, EPDM, metal systems, and asphalt shingles. Free inspections, transparent pricing, workmanship warranties. Need an estimate? Call Roof Experts at (469) 936-7663 or request your free roof inspection online.
Low-slope roofs above cooled conditioned space have to hit a three-year-aged solar reflectance of 0.55 and thermal emittance of 0.75, or an SRI of 64. Steep slope over 2:12 has its own 0.35 / SRI 29 floor. We specify to the number, pull the manufacturer's CRRC data, and put it in the submittal so plan review has nothing to argue with.
White TPO and PVC hit Austin's reflectance targets natively, which is one reason they dominate the market here. We size the membrane to the traffic and exposure — 60 mil where it is a clean roof, 80 mil where there is constant service access or a kitchen exhaust nearby.
Asphaltic systems remain the right answer on heavy-traffic roofs and on older decks where redundancy matters more than a spec sheet. Where the cool-roof rule applies, we specify a reflective cap sheet or coating that actually carries the tested numbers rather than a product that is merely light-colored.
Austin's 2024 IWUIC applies to the construction, alteration, repair and maintenance of any building or structure inside a WUI area, and more than half the city is in one of the three zones. That means Class A coverings, sealed or capped gaps, metal flashing over underlayment in valleys, noncombustible skylight frames, and no vegetative roofs. We verify the site rather than trusting the map, as the City itself advises.
Austin permits private roll-off service for construction waste, but the hauler must hold a City license, run City-inspected vehicles, and carry its name and phone number on both sides of the truck and on at least one side of every container. We use licensed haulers. Ask any bidder whose box is going on your lot.
Retail, medical, restaurant and office work gets sequenced so the tenant keeps trading and nothing is open overnight. Austin's practical work window is 7:00 a.m. to 10:30 p.m. under City Code Sec. 9-2-3(A)(2); a jobsite radio is capped separately at 75 decibels and barred entirely between 10 p.m. and 10 a.m.
Full roof walk, moisture cores, drainage assessment, and a verification of whether the property sits in a Wildland-Urban Interface zone — because that single fact changes the covering, the valley detail and the permit path.
Membrane, insulation, tapered design and the reflectance and emittance values that Austin's C402.4 requires, with the manufacturer's tested data attached. If your scope falls under the repair exemption — the lesser of 50% of the roof or 20 squares — we tell you that, because it is a real cost difference.
Austin requires contractor registration with Development Services before work under a building or trade permit. We handle registration and the permit, and we build the WUI review into the timeline rather than treating it as a surprise.
Daily dry-in with no deck left open, inspections scheduled as we go, and a closeout package: permit, product data with the reflectance values, warranty registrations, core findings and completion photographs.
Heat-welded seams and a white reflective surface that meets Austin's cool-roof targets without a coating. PVC earns its premium where grease, chemical exhaust or a commercial kitchen is involved; TPO carries the rest of the market.
Two-ply asphaltic systems handle constant foot traffic and imperfect substrates better than single-ply, and the redundancy is genuine insurance on a roof with a long repair history. Reflective cap sheets keep them compliant where the cool-roof rule reaches.
This is where Austin differs from every DFW city. A pitched commercial roof over 2:12 — a hotel, a church, a mixed-use building, a school — has to carry a material at 0.35 reflectance or SRI 29. Not every architectural shingle line does, and the ones that do are not always the ones a supplier pushes first.
Five years on our labor for a full commercial system, in writing, with the scope it covers stated. Repairs and partial scopes carry a shorter term and the contract says so plainly.
No-dollar-limit system warranties of 15 to 20-plus years where the building and the scope qualify, installed by a certified crew with a manufacturer field inspection. We tell you whether yours qualifies before you budget around it.
Permit, WUI verification, reflectance and emittance data for the installed products, warranty registrations, moisture findings and completion photographs. Austin's energy code makes that file worth keeping.

Yes, and it is one of the few places in Texas that does. Austin's amended IECC Section C402.4, adopted by Ordinance No. 20250410-038 and effective 10 July 2025, ends with this sentence: roof surfaces with an incline greater than 2 units vertical in 12 units horizontal shall incorporate a roof material having a minimum reflectance of 0.35 or a minimum initial SRI of 29. The same sentence is repeated in Austin's ASHRAE 90.1-2022 compliance path. The model code does not impose it. If a bidder quotes you a steep-slope commercial roof in Austin without naming the reflectance value of the product, they have not read the code.
For low-slope roofs directly above cooled conditioned space in Climate Zones 0 through 3, you comply through Table C402.4 — the headline targets being a minimum three-year-aged solar reflectance of 0.55 with a minimum three-year-aged thermal emittance of 0.75 tested to CRRC S100, or a minimum Solar Reflectance Index of 64 determined under ASTM E1980. There is a substantial exemption list: PV systems, solar thermal, vegetative roofs, above-roof decks and walkways, skylights, HVAC and other opaque rooftop objects, roof area shaded at peak sun angle on the summer solstice, ballasted roofs at 17 psf stone or 23 psf pavers, and roofs where at least 75% of the area meets one of those exceptions.
Not a small one. Austin's C402.4 exempts repairs to roof surfaces when the repair does not exceed the lesser of 50% of the roof surface or 20 squares — 2,000 square feet. That is a genuinely useful threshold to know before you scope a project, because staying under it can be the difference between a straightforward repair and a full compliance exercise. We will tell you which side of the line your job falls on rather than letting you find out at plan review.
More than half of Austin is, per the City's own statement, across three WUI zones. Austin adopted the 2024 International Wildland-Urban Interface Code by Ordinance No. 20250410-041, effective 10 July 2025, and the amended scope section applies it to the construction, alteration, movement, repair, maintenance and use of any building, structure or premises in a WUI area. There is an interactive map, but the City itself cautions that the map is meant to help applicants get started and cannot replace verifying the site. We verify.
Class A rated roof coverings with gaps sealed or capped; metal flashing over underlayment in valleys; noncombustible frames and compliant glass for skylights; and no vegetative or green roofs. Wood shake and wood shingle coverings are banned outright in the WUI area regardless of distance from the wildland, including fire-retardant-treated wood. There is also a specific rule for anything installed over the roof assembly — solar racking, most commonly — requiring it not compromise the assembly's ASTM E108 or UL 790 rating.
In Austin, yes — with a condition. City Code expressly permits a private licensed collection service for solid waste generated in connection with construction activities, and the City may not charge you for using one. But the hauler has to hold a City license, run City-inspected vehicles, and display its name and phone number on both sides of each vehicle and on at least one side of each container. That is a different regime from some North Texas cities, where a municipal container is mandatory.
Serious, and worth understanding properly. In the NOAA record for 2000–2025 there were 70 distinct hail days within ten miles of Austin — 46 with stones of an inch or more, 22 at 1.75 inches or more, 10 at two inches or more. The 25 March 2009 storm produced an NWS-estimated $160 million in losses, described in the record as the most ever for an Austin hail storm, and the notable pattern is that Austin's three costliest hail storms all fell on a 25 March. More recently, 24 September 2023 brought three-inch hail to Brentwood and Fiskville in a complex NCEI estimated at $300 million of damage in Travis County alone — a September event, well off Austin's normal March-through-June pattern.
No, and we would rather give you the honest number than the alarming one. Distinct hail days within ten miles of Austin fell from 30 in 2000–2009 to 25 in 2010–2018 to 15 in 2019–2025. What rose sharply is reports per day — from 3.10 to 5.40 — because 59 of the 81 reports since 2019 came from public crowdsourced submissions, and a single day, 24 September 2023, generated 25 reports on its own. Anyone selling you an Austin roof on a rising report count is quoting the wrong statistic.
Free inspection, honest scope, real warranty. Most service work scheduled within 24–48 hours.
