Fast, Reliable Roof Installation Across Austin
A full roof installation on an Austin home typically runs $11,500 – $28,000 depending on the shingle grade, roof complexity, and whether we’re replacing decking. Most jobs take three to five working days once materials are staged. If you’re calling from Allandale, Circle C, or out toward Hamilton Pool Road, we know the terrain and the traffic patterns, and we schedule accordingly. Call (361) 202-8874 for a free, written estimate before any work begins.

What makes roof installation in Austin different isn’t just the heat or the hail. It’s the split between city and county rules. A roof on a lot inside Austin city limits follows one set of permits and inspections. A roof on five acres off Hamilton Pool Road or out near Spicewood follows Travis County’s rules instead, which means different setbacks, different inspectors, and different planning. We handle both, and we’ll tell you which one applies to your address before we quote a dollar figure.
Key Takeaways for Austin Homeowners
- Austin roof installation costs $11,500 – $28,000 for most homes, with shingle tear-off and replacement accounting for the bulk of the job.
- Out-of-city acreage falls under Travis or Williamson County permitting, not City of Austin, and septic and well setbacks can change where a dumpster or material delivery can go.
- Many 1950s-era homes in Allandale and Crestview have spaced board sheathing that needs an OSB overlay before modern shingles go on.
- Every Mercer Roofing technician arrives with a photo ID badge, and their name and photo are sent to you before they show up.
- The 365-Day Done Right Promise covers your roof for a full year after installation. If something’s not right, we make it right.

Why Mercer Roofing Co Austin Is Austin’s Preferred Roof Installation Company
Mercer Roofing Co Austin is part of the Threshold Group family, founded in 2000. That matters because every location is independently owned and operated but held to the Threshold Verified standard: background-checked, identity-verified, photo-badged technicians on every visit. You’ll know who is walking up your driveway before they ring the bell. We send the technician’s name and photo ahead of the visit, and they badge in at the door with a photo ID. For homeowners in Austin who are home alone, or who have young kids, or who simply don’t want a stranger at the door without proof of who they are, that’s the difference that matters.
Our crews have worked roofs from Brentwood to Buda, from Manor to Dripping Springs. We know which Austin neighborhoods have original 1950s decking, which have tile, and which get hammered by hail from the west-moving spring storms. We pull permits when they’re required, we pass inspections, and we put every price in writing before the first nail goes in.
TPO Roofing Installation in Austin
TPO Roofing Installation in Austin runs $9.50 – $14.00 per square foot installed, and it’s the right call for the low-slope and flat roof sections you see on mid-century modern and ranch homes across central Austin. TPO is a heat-welded thermoplastic membrane that reflects UV rather than absorbing it, which matters in a city where July attic temperatures routinely push past 140 degrees. On acreage properties with detached shops, carports, or accessory structures, TPO is often the most cost-effective membrane system for a flat or nearly flat roof.
When TPO Makes Sense on Austin Homes
The mid-century ranches in neighborhoods like Allandale, Crestview, and Brentwood often have a low-slope section over a carport, a porch, or a rear addition. Composition shingles should not be installed below a 2:12 pitch, so those sections need a membrane. We install TPO in white or tan, heat-weld the seams for a watertight bond, and flash it into the shingle sections properly. On acreage, we regularly install TPO on detached garages, barns, and workshop roofs where a metal or shingle roof would require more framing than the structure can carry.
What a Mercer TPO Installation Includes
Every TPO job starts with a written price that covers tear-off of the old membrane, deck inspection, any required OSB replacement, new insulation board if needed, the TPO membrane fully adhered or mechanically fastened per manufacturer spec, and edge metal and flashing. We install TPO from manufacturers we trust, and the 365-Day Done Right Promise applies to every membrane job we do.
Shingle Roof in Austin
Shingle Roof installation in Austin runs $5.50 – $8.50 per square foot for architectural shingles with tear-off, which puts most full replacements between $11,500 and $22,000. Asphalt shingles remain the most common roof on Austin homes, from the 1970s-2000s brick veneer tract houses in the suburbs to the historic bungalows closer to downtown. The key is matching the shingle grade to the home’s exposure and pitch, and making sure the deck, underlayment, and ventilation underneath are done right.
Composition Shingle Replacement, Done for Austin’s Climate
Austin’s sun is brutal on shingles. Intense UV exposure accelerates granule loss, and spring hailstorms crack and bruise shingles faster than most homeowners expect. When we install, we use shingles from GAF, CertainTeed, and Owens Corning because those manufacturers publish wind and hail ratings that hold up to what we actually see in Central Texas. We also inspect and, where needed, correct attic ventilation. A well-ventilated attic keeps the shingle deck cooler, and cooler decks mean shingles that last longer.
Hail Damage and Impact-Rated Shingles
If your Austin roof has taken hail, the replacement decision isn’t just cosmetic. Impact-rated shingles, like the Class 4 options from CertainTeed and GAF, resist hail damage better than standard three-tab. The price difference runs $1.50 – $2.50 more per square foot, and for homes in hail corridors west of I-35, that upgrade often pays for itself before the next storm season ends. We’ll show you samples and give you the honest numbers for both options.
Trusted Brands We Service in Austin
We install and repair shingle roofs using GAF, CertainTeed, Owens Corning, and IKO products. We stick to manufacturer-recognized brands because we can stand behind them, and because we know their wind, hail, and UV ratings hold up to what Austin roofs actually face. For TPO membrane jobs, we source from manufacturers with proven heat-weld systems and Texas distribution, so we’re not waiting on a truck from out of state when your roof is torn off. On acreage properties, we order full squares plus waste factor and stage materials where the county says we can, not where it’s convenient for us. Your shingle dye lots match, your job doesn’t stall waiting for a second run, and the dumpster goes where it won’t crush a drain line.

If you’re deciding between brands, we’ll show you side-by-side samples and published specs. We don’t push one brand. We push the one that fits your roof pitch, your exposure, and your budget.

AfterCommon Roof Installation Problems We See in Austin Homes
- Spaced board sheathing on 1950s-era roofs. Homes in Allandale, Crestview, and Rosedale frequently have 1×6 or 1×8 boards with gaps between them instead of plywood. Modern shingles require a solid deck, so we overlay 7/16 OSB before underlayment and shingles go on. Skipping this step is why some Austin roofs fail prematurely after a re-roof.
- County jobs that skip inspections. Out-of-city acreage in Travis or Williamson County doesn’t always require a county inspection for a re-roof. That loophole lets low-bid crews under-drive nails and walk away. We pull the permit and get the inspection even when the county doesn’t require it, because the inspection catches what a bad crew would hide.
- Septic and well conflicts during tear-off. On acreage lots, the dumpster and material staging can’t go just anywhere. A dumpster dropped on a septic drain field or a material truck parked over a well line can cause damage that costs thousands to repair. We map setbacks before we stage anything.
- Mismatched shingle dye lots from under-ordering. Long hauls to outlying Austin acreage make some roofers order tight and hope it works out. It doesn’t. Partial squares from different dye lots leave a visible patch on the roof. We order full squares with waste factor, and we stage extras on-site so the job doesn’t stall.
Pricing for Roof Installation in Austin, TX
For a standard composition shingle replacement in Austin, expect $5.50 – $8.50 per square foot installed, including tear-off, disposal, underlayment, and labor. A typical 2,000-square-foot roof lands between $11,500 and $17,000. Architectural shingle upgrades, Class 4 impact-rated shingles, new decking, and steep-pitch or cut-up roof lines push the higher end. TPO membrane installation on low-slope sections runs $9.50 – $14.00 per square foot. Metal and tile are a different conversation, and we’ll give you those numbers if the roof calls for it.
What changes the price: roof pitch, number of stories, whether we’re replacing the deck, how many valleys and penetrations, whether the county or city is permitting the job, and yes, whether septic or well setbacks limit where the dumpster can go. We don’t quote a ballpark and then change it. Grant Whitlock’s rule is simple: we measure, we walk the roof, we put every dollar in writing, and the price you see is the price you pay.

FAQs About Roof Installation in Austin
If your property is outside Austin city limits, you go through Travis County or Williamson County, not the City of Austin. County permitting is often lighter than city permitting, and on some re-roofs no permit is required at all, but we pull one anyway when the county allows it. A county inspection gives you a third-party check on the work. Call (361) 202-8874 and we’ll confirm which jurisdiction applies to your address.
Septic drain fields and well heads have required setbacks, and we can’t park a dumpster or a loaded material truck on top of them. On a 10-acre lot that sounds easy to work around, but the house, driveway, and septic system often cluster together. We map the septic field and well location before we stage anything, and the dumpster goes on stable ground outside the setback. Crushing a drain line or cracking a well head during tear-off is an expensive avoidable mistake, and we don’t let it happen.
Yes, it is. Spaced board sheathing, common in Allandale, Crestview, and other 1950s Austin neighborhoods, has gaps between the boards that modern shingles can’t bridge reliably. We overlay the existing boards with 7/16 OSB decking, then install underlayment and shingles over the new deck. On an acreage property off Hamilton Pool Road, our crew did exactly this on a 1970s ranch: overlaid the spaced boards with 7/16 OSB, installed GAF Timberline HDZ architectural shingles with full ice and water shield in the valleys, and corrected the soffit-to-ridge ventilation after hail had stripped granules from the original three-tab. The roof now drains properly, vents properly, and holds a full warranty.
Acreage lots sit open to the wind. No tree canopy, no neighboring homes to break the gusts that sweep across open land west of Austin. Valleys and flashing take the brunt of wind-driven rain, so we use full ice and water shield membrane in valleys, wider flashing at sidewalls, and proper kick-out flashing at roof-to-wall transitions. City roofs get the same standard from us, but on open acreage the difference between good flashing and average flashing shows up after the first storm season.
Water that pools around the foundation or runs back toward the house can rot fascia boards, undermine the drip edge, and shorten the life of the roof system. On acreage, we check how the lot drains before we install. If downspouts are dumping water against the foundation or if a low spot is holding water near the eaves, we’ll tell you before the roof goes on. Fixing drainage is a small cost compared to replacing rotted roof decking five years from now. Call (361) 202-8874 and we’ll walk the property with you.
