Styles & brands we work with
Shingle Roof
A shingle roof is the most common roof installation in Austin for good reason: it’s affordable, it’s fast to install, and modern architectural shingles can handle Texas sun, hail, and heavy rain. Shingles are available in asphalt and composite varieties, laid in overlapping rows over roof decking and underlayment. A typical our Roof Installation in Cedar Park and Austin runs $8,500 to $14,500 for an average single-family home, depending on square footage, tear-off requirements, and shingle grade. Mercer Roofing Co Austin works with manufacturer-recognized brands like GAF and CertainTeed, so you get a roof that’s installed to the manufacturer’s specification, not a shortcut job.
Architectural vs. Three-Tab
Architectural shingles are thicker, hold up better against wind, and carry longer warranties. They also cost more, but in Austin’s hail-prone climate, the upgrade usually pays for itself. Three-tab shingles are thinner and less expensive, though we install far fewer of them now that architectural pricing has come down.
Decking and Underlayment
We inspect decking before any shingle goes down. Rotted or spongy decking has to be replaced, and we’ll show you photos of what we find so the price adjustment on decking is never a surprise. Underlayment gets installed over the decking as a secondary water barrier, which matters in Austin when heavy thunderstorms push water sideways.
Standing Seam Metal Roof
A standing seam metal roof is a premium roof installation in Austin that uses interlocking vertical metal panels with concealed fasteners. It’s the roof type we recommend for homeowners who want something that lasts 40 to 60 years and shrugs off hail better than any shingle. Standing seam metal roof installation in Austin typically runs $18,000 to $32,000 for an average home. You’re paying for material longevity, but also for labor: every panel is cut and seamed on site, and the detailing around valleys, hips, and penetrations takes real skill. Mercer Roofing Co Austin installs standing seam systems that are engineered for Central Texas wind loads and thermal expansion.
Concealed Fasteners vs. Screw-Down Panels
Standing seam is the type that hides fasteners entirely, which means no exposed screws to back out over 20 years of thermal cycling. Screw-down ag panels are cheaper and common on barns, but we don’t recommend them for residential homes in Austin. The savings disappear when rubber washers fail and leaks start at the fastener holes.
Thermal Movement and Panel Design
Austin’s summer sun heats metal panels to 150 degrees and beyond. Standing seam systems are designed with floating clips that let panels expand and contract without working loose or oil-canning. It’s the reason this roof type survives decades here while cheaper metal systems warp.
Tile Roof
A tile roof is a Roof Installation in Bastrop and Austin that uses clay or concrete tiles, and it’s a favorite in neighborhoods like Lost Creek, Shady Hollow, and parts of Lakeway where homeowners want the look of a Spanish or Mediterranean home. Tile roofs in Austin run $16,000 to $28,000 on average, with clay at the higher end and concrete more moderate. Tiles last 50-plus years, but the underlayment beneath them does not. In our experience, the most common tile roof failure we see in Austin isn’t broken tile; it’s failed underlayment that goes unnoticed for years. Mercer Roofing Co Austin installs tile over new high-grade underlayment and follows the same written-price rule: no surprises when we’re done.
Clay vs. Concrete
Clay tiles are fired and hold their color for decades, but they’re brittle, and foot traffic during installation has to be careful. Concrete tiles are heavier and more uniform, and they cost roughly 20 to 30 percent less. Both work well in Austin’s climate, but the roof framing has to be rated for the extra weight.
Underlayment Is the Real Waterproof Layer
Tile sheds water, but the underlayment is what keeps your home dry when wind-driven rain gets under the tile. We use high-grade synthetic or double-layer underlayment on tile jobs specifically because it has to last as long as the tile above it. It’s the difference between a tile roof that makes it 50 years and one that leaks at year 15.
Roof Ventilation
Roof ventilation is the system of intake and exhaust vents that moves hot air out of your attic, and it’s part of every complete roof installation in Austin. Without working ventilation, attic temperatures in Austin summers can hit 140 degrees or higher. That heat radiates into your living space, drives up cooling bills, and cooks shingles from underneath, cutting their lifespan short. Mercer Roofing Co Austin calculates ventilation based on your attic’s square footage and the specific vent type, so you get actual air movement, not just a decorative box vent. Ventilation work as part of a roof installation typically adds $800 to $2,500 depending on the layout.
Intake and Exhaust Balance
Ventilation only works when intake and exhaust are balanced. Intake comes from soffit or eave vents, and exhaust goes out the ridge or upper roof. If you add ridge vents without enough intake, the system pulls air from the living space, which makes your AC work harder.
Ridge Vents, Box Vents, and Powered Options
Ridge vents run along the peak and are nearly invisible from the street, which is why most Austin homeowners choose them. Box vents are simpler and work well for smaller roofs. Powered attic fans can help on low-slope designs, though we spec them carefully because an oversized fan can depressurize the attic and pull conditioned air out of the house.
Roof Flashing Installation
Roof flashing installation is the process of sealing the joints where roof planes meet walls, chimneys, skylights, and pipes. Flashing is thin metal, usually aluminum, galvanized steel, or copper, bent and installed in layers to direct water away from these vulnerable transitions. In Austin, most roof leaks we see trace back to bad flashing, not bad shingles. The shingles can be perfect, but if the flashing around a pipe boot or chimney rusted through, water gets in. New flashing installation ranges from $400 for a single pipe boot replacement up to $2,000 to $4,000 when we’re re-flashing chimneys and sidewalls as part of a full roof installation. Mercer Roofing Co Austin replaces flashing on every full install and on any repair where the existing metal is suspect.
Step Flashing at Sidewalls
Where a roof plane dies into a vertical wall, step flashing is woven between each course of shingles and the wall siding. It’s tedious work, and it’s one of the first places shortcuts show up on cheap roof jobs. We use pre-bent step flashing and counter-flashing so water can’t track behind the siding.
Chimney and Pipe Boots
Chimney flashing has multiple pieces: base flashing, step flashing, counter-flashing, and a saddle or cricket behind the chimney to divert water. Pipe boots are simpler but in Austin’s sun, rubber boots crack and split in as little as eight to ten years. We replace every pipe boot on a full roof installation so the new roof isn’t undermined by old rubber.
TPO Roofing Installation
TPO roofing installation is the process of heat-welding single-ply thermoplastic membrane to flat or low-slope roofs, which is common on Austin homes with modern architect-designed flat sections, carports, or patio covers. TPO is white by design, reflecting solar heat instead of absorbing it, which keeps the rooms below cooler in a Texas summer. TPO installation on a typical residential flat section in Austin runs $6 to $10 per square foot, so a 1,000-square-foot flat roof would land in the $6,000 to $10,000 range. Mercer Roofing Co Austin installs TPO systems with heat-welded seams, which are stronger than the tape-and-caulk methods some contractors still use.
Heat-Welded Seams vs. Adhesive
Heat-welded TPO seams fuse the membrane into a single, continuous sheet. It’s the manufacturer-specified installation method and it’s the reason TPO roofs regularly last 20 to 25 years. Adhesive or taped seams save time on install day, but they’re the first place a TPO roof fails.
When a Leak Comes from Above
Flat roof leaks are harder to chase because water can puddle and travel far from the point of entry. TPO membrane makes leak detection more straightforward because the surface is uniform and accessible. If you’ve had a flat roof leak that keeps coming back, it’s often an early signal the membrane has reached its service life and should be replaced rather than patched again.
Brands We Service
Mercer Roofing Co Austin installs GAF shingle systems, and we’ve put enough GAF Timberline roofs on Austin homes to know their nailing patterns and warranty requirements cold. GAF’s Golden Pledge warranty is only available through certified installers, and we install to the standard that makes the warranty valid, not just the roof watertight.
CertainTeed is the other shingle brand we regularly install in Austin, and their Landmark line has a strong local track record. We also work with Tamko, Boral, and Owens Corning products depending on the home and the homeowner’s priorities. Whether you have a GAF roof, a CertainTeed roof, or any other manufacturer’s material, we can help. Our team is trained on manufacturer specs, not generic installation habits.

- Granules in your gutters. Shingle granules wash down as the protective surface wears away. If you’re seeing a steady buildup in your Austin gutters, the shingles are losing their UV shield and are on the back half of their life.
- Curling or lifting shingle edges. Shingles that curl at the edges have become brittle. Austin’s heat accelerates this, and once shingles curl, wind gets under them and tears them off during the next storm.
- Daylight visible from the attic. If you can see light through the roof deck from inside the attic, water can also get through. This is a direct signal your roof installation in Austin has failed or is actively failing.
- Water stains on ceilings or wall tops. Stains mean water has already penetrated the roof and run down through the framing. The leak you can see is often not where the roof hole is.
- Sagging rooflines or soft decking. A roof deck that bounces or feels spongy when walked on is losing structural integrity. In Austin, extended humidity plus small leaks can rot decking quietly for years before anyone notices.
If you’re seeing any of these, call (361) 202-8874. A roof issue left alone always gets more expensive, but you don’t have to make the repair decision over the phone. We’ll inspect it, show you what we find, and give you a written price. Then you decide.

How Much Does Roof Installation Cost in Austin?
A typical shingle roof installation in Austin runs $8,500 to $14,500 for an average single-family home. Standing seam metal runs $18,000 to $32,000, tile comes in at $16,000 to $28,000, and TPO on flat sections runs $6 to $10 per square foot. Roof ventilation adds $800 to $2,500, and flashing work can add $400 to $4,000 depending on how many penetrations and transitions your roof has.
What moves the price? Square footage and roof pitch are the big ones. Steep roofs take longer and require more safety rigging. The condition of the decking matters too; in Austin’s humidity, older homes in neighborhoods like Brushy Creek and Hutto often need Hutto Roof Installation decking replacement that a brand-new home in Wells Branch doesn’t. Shingle grade moves the price, as does the number of valleys, dormers, and pipe penetrations. The cheapest way to protect yourself isn’t finding the lowest bid; it’s getting a written, line-item price and a written guarantee, both of which Mercer Roofing Co Austin provides on every job.

Frequently Asked Questions About Roof Installation in Austin
Roof installation is the complete process of removing the old roofing material and installing a new roof system, including decking repair, underlayment, flashing, ventilation, and the final roofing material itself. It’s different from a roof repair, which addresses a specific problem area. A full roof installation in Austin is the right move when the existing roof is past its service life or when recurring repairs no longer make financial sense.
Most shingle roof installations in Austin take two to four days from tear-off to final cleanup. Standing seam metal and tile roofs take longer, typically five to ten days depending on the roof’s complexity.
