New Construction in Austin, TX

New Construction in Austin, TX

New construction roofing in Austin means installing a roof on a brand-new home, addition, or detached structure from the deck up. It typically costs between $9,500 and $24,000 depending on square footage, roof complexity, and shingle brand, and most new construction roofs take 3 to 7 days from tear-off of any temporary covering to final inspection. If you’re building a custom home in Barton Hills, adding a second story in Crestview, or putting a workshop behind your house in Oak Hill, you’ll want a roofer who understands Central Texas heat, hail, and the specific code requirements for Travis County. Mercer Roofing Co Austin handles new construction roofing from the first nail to the final walkthrough, and you can reach us at (361) 202-8874 for a free estimate.

This page covers what new construction roofing involves, when you need it, how we build it, and what it costs in Austin. If you’re replacing an existing roof instead of building new, see our Roof Replacement & Installation in Austin page for details on that process. And if you’re just starting to explore your options, our home page walks through every service we offer.

When You Need New Construction

New construction roofing isn’t the same as re-roofing an existing house. It starts with bare decking, which means every layer matters: the underlayment, the flashing, the shingles, the ventilation. You need this service in specific situations, and here’s what they look like in Austin:

• Building a custom home: Your builder may handle the roof, or you may be acting as your own general contractor. Either way, you need a roofer who coordinates with framers, electricians, and HVAC crews. In neighborhoods like Mueller and East Austin, where new builds are common, we sequence our work so your roof goes on right after the decking passes inspection and before interior finishes begin.
• Adding a room or second story: A new master suite over the garage in Allandale or a home office addition in Rosedale means new roof area that has to tie into the existing roof. The flashing where old meets new is where leaks show up, and it has to be done correctly the first time.
• Building a detached structure: A guest house, studio, or oversized garage in Tarrytown or Circle C needs its own roof built to the same standard as your main house. We treat a 400-square-foot casita with the same care as a 4,000-square-foot home.
• New construction after a storm or fire: If you’re rebuilding from the ground up after hail damage or a structure fire, you need a roofer who works with your insurance timeline and your rebuild schedule. We’ve handled post-loss new construction in Pflugerville, Round Rock, and across Travis County.
• Spec homes and investment properties: If you’re building to sell or rent, a well-built roof with a documented warranty adds real value. Buyers notice the shingle brand and the paperwork.

Our New Construction Process

Here’s how a new construction roof goes with Mercer Roofing Co Austin, from the first phone call to the final walkthrough:

1. Initial consultation and written estimate: Call us at (361) 202-8874. A live person answers, not a voicemail tree, not a call-back form. We’ll ask about your project: square footage, roof pitch, structure type, timeline. Then we schedule a site visit. Before we leave, you get a written price for the entire job. We don’t start work without it, and the price doesn’t change unless you change the scope.
2. Decking inspection: We walk the bare roof deck and check for gaps, warped sheathing, and proper nailing. If the decking wasn’t installed by the framer with the right spacing or fastener schedule, we flag it before we put anything on top. In Austin’s climate, decking that flexes in summer heat leads to shingle damage within a few seasons. We won’t roof over a deck that isn’t right.
3. Underlayment and ice-and-water shield installation: We install high-quality synthetic underlayment across the entire deck, with ice-and-water shield in the valleys, around penetrations, and along eaves. This is the layer that protects your home between the shingles and the wood. In Austin, our big concern isn’t ice dams, it’s wind-driven rain and the occasional hailstorm, so we take the time here.
4. Flashing installation at every transition: Chimneys, skylights, vents, wall intersections, dormers: every place where the roof plane changes or meets another surface gets custom flashing. We cut and bend flashing on-site to fit your specific roof, rather than relying on generic pre-formed pieces that leave gaps.
5. Shingle installation with manufacturer specifications: We install your chosen shingles, from brands like GAF, CertainTeed, or Owens Corning, exactly to the manufacturer’s nailing pattern and installation requirements. This matters because it’s what keeps your manufacturer warranty valid. We don’t cut corners on nail count or placement.
6. Final inspection and walkthrough: When the roof is complete, we inspect every seam, every flashing point, and every shingle. Then we walk the roof with you or your builder, answer questions, and hand over your written guarantee. You get 365 days of coverage: if anything isn’t right within that year, we come back and make it right, no charge.

Before we ever step onto your property, you’ll know who’s coming. We send the technician’s name and photo ahead of the visit. When they arrive, they’ll be in a clean, marked uniform with a photo ID badge. That’s the Threshold Verified standard, and it’s non-negotiable for every Mercer technician, on every job, including new construction sites where you may not be present every day.

New Construction Pricing in Austin

New construction roofing in Austin typically runs $450 to $650 per square, which is 100 square feet of roof area. For a 2,000-square-foot home with a simple roof, that means roughly $11,000 to $15,000. A 3,000-square-foot home with multiple hips, valleys, and a steeper pitch will land closer to $16,000 to $22,000. Here’s a breakdown by component:

Component	Typical Cost Range
Architectural asphalt shingles (per square)	$180 – $320
Underlayment (per square)	$60 – $100
Flashing, vents, and accessories (per job)	$800 – $2,500
Decking repair or replacement (per sheet, if needed)	$65 – $100
Labor and installation (per square)	$150 – $250
Total per square	$450 – $650

What moves the price? Roof pitch is the biggest factor: a 4/12 pitch is fast and safe to work, while an 8/12 or steeper slows everything down. Complexity matters too, with more hips, valleys, and penetrations meaning more cutting, more flashing, and more time. Shingle brand plays a role: Owens Corning and GAF architectural lines cost less than premium CertainTeed or specialty Boral products. And if your decking has been exposed to rain during framing, you may need to replace sheets before we can proceed.

We give you a written price before any work starts, and that price is the price. No surprises on the invoice. If you’re budgeting a new build, call us at (361) 202-8874 with your plans and we’ll give you a realistic number to work with.

Why Austin Homeowners and Builders Choose Mercer Roofing

New construction is about getting it right before the interior ever goes in. Once drywall is up and paint is on the walls, a roof leak becomes a much bigger problem. Austin’s weather doesn’t help: we get intense UV exposure that breaks down cheap materials, spring hailstorms that test impact resistance, and sudden downpours that find every gap in flashing. A roof built to Code minimum will survive. A roof built to manufacturer specification with proper attention to transition points will last decades.

We were founded in 2000 and have been part of the Threshold Group family of home-service companies since our Austin location opened. That means every technician who comes to your job site is background-checked, identity-verified, and held to the Threshold Verified standard. Not once in a while; on every single visit. When you’re building a home, you have enough moving parts to manage. Your roofer shouldn’t be a question mark.

Our 365-Day Done Right Promise covers every new construction roof we install. Within one year of installation, if anything isn’t right, we fix it. No deductibles, no runaround, no “that’s within tolerance.” We put it in writing because we expect to keep it.

Shingle Brands We Recommend for Austin New Construction

We install new construction roofs using manufacturer-recognized shingle brands, and the right choice for your project depends on your budget, your home’s style, and how long you plan to own the property.

• GAF Timberline: The most common architectural shingle we install. Strong performance in hail tests, wide availability, and a solid manufacturer warranty. Priced in the middle of the range.
• CertainTeed Landmark: A step up in curb appeal, with deeper shadow lines and better color retention in Austin’s sun. A good choice if your new build is in a neighborhood like Tarrytown where the roof is highly visible.
• Owens Corning Duration: Known for its SureNail strip and strong wind ratings. We recommend it when the structure sits on an exposed ridge or hilltop, where wind uplift is a real concern.

We’ll walk through the options with you and give you honest guidance. We don’t push a brand because of a spiff; we recommend what fits your roof and your budget.

Building Codes and Permits in Austin

New construction roofing in Austin falls under the City of Austin’s residential building code, which adopts the International Residential Code with local amendments. Your project will need a permit before the roof goes on, and your final inspection checks for proper nailing, underlayment, flashing, and ventilation. If you’re building in unincorporated Travis County, the process is similar but handled through the county. We coordinate with your builder or you directly to make sure the roof is scheduled for inspection at the right time. A roof that fails inspection means delays and rework, and we’d rather do it once.

Austin also has specific wind zone requirements depending on where your property sits. Homes on the west side near the Hill Country often fall into higher wind exposure categories than homes in central Austin, which changes fastener requirements. We factor this into the written estimate so there are no surprises when the inspector arrives.

FAQs – New Construction

How much does new construction roofing cost in Austin?

New construction roofing in Austin typically costs between $9,500 and $24,000, with most projects landing around $450 to $650 per square. The final number depends on roof pitch, complexity, shingle brand, and whether the decking needs repairs before installation. Call (361) 202-8874 for a free, written estimate specific to your project – we’ll walk the site and give you a real number before you commit.

How long does a new construction roof take?

Most new construction roofs take 3 to 7 days from start to final inspection. A simple 2,000-square-foot roof with a moderate pitch can often be done in 3 to 4 days. Complex roofs with steep pitches, multiple dormers, or tile or slate materials take longer. Weather delays are common in Austin spring storm season, and we’ll communicate with you throughout the process.

Can you work with my builder or general contractor?

Yes. We work with builders and GCs across the Austin metro on a regular basis, including custom home builders in Westlake, Mueller, and Steiner Ranch. We sequence our work to fit your construction timeline, coordinate with other trades, and make sure the roof is ready for inspection when the time comes. If you need us to communicate directly with your builder, we’ll do that, and you’ll still get the written price and guarantee.

What warranty comes with a new construction roof?

Your new construction roof includes two layers of coverage: the manufacturer’s warranty on the shingles, which varies by brand and product line, and Mercer’s 365-Day Done Right Promise, which covers workmanship for a full year after installation. If anything isn’t right within that year, we come back and make it right, at no cost to you. That promise is in writing, and it’s included with every job.
