New Construction in Dallas, TX

New Construction in Dallas, TX

New construction roofing in Dallas means installing a roof on a home that never had one before, whether it’s a custom build in Lakewood, a spec home going up in Frisco, or an infill project in East Dallas. A new-construction roof is a different animal from a reroof: the decking is fresh, the walls aren’t settled yet, and the roofer has to coordinate with framers, electricians, and HVAC crews who are all working on the same structure at the same time. Mercer Roofing Co Dallas handles new-construction roofing from the first delivery of decking to the final shingle, with a written price before any work starts and a 365-Day Done Right Promise behind every nail. If you’re building a new home and need a roof that will pass inspection the first time and hold up to Dallas hail for decades, call us at (432) 302-5605. This page sits under our broader Roof Replacement & Installation service line, but new construction is its own specialty, and it deserves its own conversation.

What makes new-construction roofing different is that nothing about the house has settled yet. The framing is fresh, the decking is clean, and the roofer’s job is to create a watertight envelope on a structure that will shift, settle, and flex for the first two years. Get the flashing details wrong on a new build, and you’ll see leaks in places a reroof never leaks. Get the ventilation wrong, and you’ll cook the attic before the first summer is over. Get the underlayment wrong, and you’ll be tearing off a roof on a house that’s barely been lived in. We’ve been doing work like this in the Dallas area for years, and we’ve learned exactly where new-construction roofs fail when the roofer cuts corners or rushes the job. We don’t cut corners, and we don’t rush.

When You Need New Construction

If you’re reading this, you’re probably in one of a handful of situations. Here are the most common ones we see across Dallas and the surrounding cities:

• You’re building a custom home from the ground up. You’ve hired a general contractor or you’re acting as your own GC, and the roof is one of the trades you need to line up. In neighborhoods like Preston Hollow and Bluffview, we regularly work alongside custom builders who need a roofing crew that shows up when promised and doesn’t hold up the schedule.
• You’re a builder or developer running a spec home. You need a roofing partner who can price a job quickly, hit a deadline, and not leave punch-list items that scare off buyers. We work with builders in growing areas like Celina, Prosper, and Forney, where new home starts are constant.
• You’re adding a major addition that requires new roof framing. A second story, a new wing, a garage conversion, a sunroom. When the addition’s roofline ties into the existing roof, the new-construction side needs to be detailed so the tie-in doesn’t leak at the seam.
• You’ve bought a lot and you’re doing an owner-builder project. You’re acting as your own contractor and you need subs you can trust. You’ll appreciate that we put every price in writing before work starts, because owner-builders get burned by vague estimates more than anyone.
• You’re replacing a roof that was installed incorrectly on a newer home. This happens more than you’d think in fast-growing North Texas subdivisions. A volume builder’s roofing sub rushed the job, and now a 4-year-old roof in Little Elm is failing. In that case, you need a reroof, but the fixes require the same attention to detail as new construction because the original work was done so poorly.
• You’re building a detached structure. A workshop, a casita, a pool house, a detached garage in the alley. These smaller new-construction roofs need the same flashing and underlayment details as a full house, and smaller projects are exactly where sloppy work shows up fastest.

Whatever your situation, the common thread is this: a new-construction roof needs to be installed by a company that treats the roof as part of a larger building envelope, not just a pile of shingles nailed to plywood. That’s how we approach every job, from a 5,000-square-foot custom home in Highland Park to a 200-square-foot pool house in Garland.

Our New Construction Process

Every new-construction roof we install follows the same sequence. Here’s what happens when you call Mercer Roofing Co Dallas for a new-construction roof:

1. You call, and a live person answers. Not a voicemail, not a call-back form. A real human being at (432) 302-5605 takes your call, asks about your project, and schedules a site visit. If you’re calling at 2 a.m. because your framing crew needs a roof next week, you’ll still get a live person.
2. We walk the site and measure. For new construction, that means checking the framing, looking at the decking, reviewing the plans if you have them, and noting any detail areas: valleys, dormers, chimneys, skylight rough-ins, cricket locations, and tie-in points. We want to see the roof before it’s a roof.
3. You get a written price before any work starts. This is non-negotiable at Mercer. No verbal estimates, no “we’ll figure it out as we go.” You get a document that spells out the shingle brand, the underlayment type, the flashing specs, the ventilation plan, and the total price. You sign it, we start. You don’t sign it, we don’t start. It’s that simple.
4. We install according to manufacturer specs and Dallas code. Decking fastening, underlayment laps, valley detailing, flashing at every penetration. We use shingle brands including IKO, Atlas, and Tamko, chosen based on your budget, your color preference, and what’s available locally. Every install complies with Dallas building code for wind uplift and fire rating, because a roof that fails inspection costs you weeks.
5. We walk you through the finished roof. Before we consider the job done, we walk the roof with you or your builder, point out every detail, and leave you with the written guarantee and our 365-Day Done Right Promise. If anything isn’t right within a year, we make it right.

Throughout the process, you’ll know exactly who’s on your roof. Every Mercer technician is background-checked, identity-verified, and dispatched under the Threshold Verified standard. Before the crew arrives, we send you their names and photos. When they knock on the door, they’ll be in a clean, marked uniform, and they’ll present a photo ID badge. That’s the Threshold Standard, and it applies to every visit, every time, no exceptions. Grant Whitlock, our owner, holds every technician to this standard on every job, including new-construction roofs where the homeowner may never even be on site. We think that’s exactly when the standard matters most.

New Construction Pricing in Dallas

We believe in putting real numbers on the page. Here’s an honest look at what a new-construction roof costs in the Dallas area as of 2025. These are ranges, not quotes; your exact price comes in writing after we walk your site. But these numbers will help you plan before you call.

Project Type	Typical Range (Installed)	Notes
Detached garage or small outbuilding (200-400 sq ft)	$2,800 – $5,500	Architectural shingle, standard slope, no valleys
Small new home or addition (800-1,200 sq ft roof)	$5,500 – $9,500	Includes underlayment, standard flashing, one or two valleys
Typical new-construction home (1,500-2,500 sq ft roof)	$9,500 – $17,000	Architectural shingle, full flashing, ridge vent, standard pitch
Larger custom home (2,500-4,000+ sq ft roof)	$17,000 – $30,000+	Multiple valleys, steep pitches, dormers, premium underlayment
Complex rooflines with dormers, crickets, or steep slope	Add 15-35%	Labor increases with complexity; flashing details multiply

What moves the number on a new-construction roof in Dallas specifically:

• Roof complexity. A simple 6/12 gable roof over a rectangular footprint is the cheapest roof to install. Add dormers, valleys, hips, crickets, or a 10/12 pitch, and labor costs climb fast. Custom homes in neighborhoods like Lakewood and Preston Hollow tend to have complicated rooflines, and that’s reflected in their roof pricing.
• Shingle choice. A standard architectural shingle from IKO or Atlas is the workhorse of North Texas roofing and the most budget-friendly option. Upgrading to a heavier, higher-wind-rated shingle adds cost but can extend service life and may help with insurance premiums down the road.
• Underlayment spec. We can install standard synthetic underlayment, or upgrade to a peel-and-stick ice-and-water shield across the entire deck. The upgrade costs more and protects better. For new construction, we recommend it on low-slope sections and around all penetrations.
• Decking condition. On a true new build, decking should be fresh and clean. But if you’re doing a major addition that ties into existing roof, the old decking may need repair or replacement at the tie-in point, and that adds cost.
• Season and schedule. Spring and early summer are the busiest roofing months in Dallas, with high demand from both new construction and storm-repair work after hail season. If your schedule is flexible, late fall and winter can sometimes be more affordable, though Dallas winters are mild enough that we install year-round.

Every new-construction estimate from Mercer includes a written price before a single nail is driven. No surprises on the invoice. No “materials went up” phone calls. The price you sign is the price you pay. We include this because it’s the honest way to do business, and because Dallas homeowners have been burned by vague estimates too many times.

If you want an exact number for your new construction, call (432) 302-5605 and we’ll schedule a time to walk the site. The estimate is free.

Why Dallas Homeowners and Builders Choose Mercer Roofing

Dallas is a tough market for roofs. Hail the size of golf balls, 100-degree summers that bake shingles, sudden spring downpours, and the occasional freeze-thaw cycle that cracks flashing. A new-construction roof has to be built to handle all of it from day one, because it’s going to spend the next two to three decades out in that weather. Here’s what we bring to the job that most roofing companies don’t:

The 365-Day Done Right Promise

Every new-construction roof we install is covered by our 365-Day Done Right Promise. If anything we installed isn’t right within a year of the install date, we come back and make it right at no charge. That’s a written guarantee, not a verbal promise. It covers workmanship. It’s included with every new-construction job, and it’s part of the written contract you sign before we start.

Written Price Before Work Starts

We’ve said it twice already, and we’ll say it again because it matters: you get a written price before any work begins. Always. No conditions. No exceptions. If a roofing company won’t put the price in writing, that’s a signal, and not a good one. We put it in writing because we stand behind our numbers.

The Threshold Standard: You Know Who’s Coming

The roofing industry has a problem: homeowners open the door to a stranger and hope for the best. We do things differently, and it’s one of the reasons people choose Mercer even when another bid comes in lower. Before our crew arrives at your new construction site, you receive their names and photos. When they arrive, they’re in clean, marked uniforms and they present a photo ID badge at the door or to your builder. Every technician is background-checked and identity-verified under the Threshold Verified standard, which each independently owned Mercer location is contractually held to. Grant Whitlock, our owner, enforces this standard on every job. If you’re building a home and you’re not on site every day, this is the difference between hoping nothing goes wrong and knowing who’s there.

We Answer the Phone 24/7

If a storm is coming and your partially-framed roof needs tarping, you can’t wait until Monday morning. Mercer Roofing has a live person answering the phone 24/7, every day of the year. Not a voicemail. Not an automated phone tree. A real human. Call (432) 302-5605 at 2 a.m. and you’ll get a person who can help.

Manufacturer-Recognized Shingle Brands

We install new-construction roofs using shingle brands that Dallas homeowners recognize and insurance companies respect. On new construction, we often use IKO, Atlas, and Tamko architectural shingles, chosen for their wind ratings, their color options, and their availability in the Dallas market. We also work with other manufacturers, but these three tend to strike the right balance of cost, durability, and style for new North Texas homes.

New Construction Roofing Details That Matter in Dallas

New-construction roofing in the Dallas area has some specific technical considerations that you may not hear about from a roofer who mostly does reroofs. Here are the details we pay attention to, and why they matter for your new build:

Flashing at the Roof-to-Wall Intersections

Dallas building code and common sense both require step flashing and counter-flashing where a roof meets a vertical wall, like a dormer sidewall or a second-story wall. On new construction, this flashing has to go in before the siding or brick goes on. If the flashing is wrong, the fix requires tearing off siding or cutting into brick. That’s a five-figure mistake. We detail these transitions correctly the first time.

Ventilation for Dallas Summers

A Dallas attic can hit 140 degrees in August without proper ventilation. That heat radiates into the living space, drives up cooling bills, and shortens shingle life. New construction is the best time to get ventilation right, because you can spec the intake and exhaust before the insulation goes in. We calculate the right balance of soffit intake and ridge exhaust for every new roof we install.

Underlayment That Performs in a Hailstorm

Shingles take the visual beating from hail, but the underlayment is what keeps water out when shingles are compromised. On new construction, we install synthetic underlayment that’s more tear-resistant and holds up better than felt during the inevitable hail season. It’s a modest cost upgrade that pays off the first time a Dallas storm drops golf-ball hail on your new roof.

Decking Fastening Schedule

The nails that hold your decking to the trusses are the foundation of the whole roof system. Dallas wind codes require a specific fastening schedule, and we follow it to the letter. A new roof with under-fastened decking can lose whole sheets in a high-wind event. That’s not a repair. That’s a disaster.

FAQs – New Construction

How much does new construction roofing cost in Dallas?

New construction roofing in Dallas typically costs between $9,500 and $17,000 for a standard 1,500 to 2,500 square foot roof with architectural shingles, full flashing, and ridge vent. Smaller structures like a detached garage run $2,800 to $5,500, while larger custom homes with complex rooflines can run $17,000 to $30,000 or more. The main cost drivers are roof complexity, shingle brand and grade, underlayment spec, and the season. Call (432) 302-5605 for a written quote on your specific new construction. Estimates are free.

How long does a new construction roof take to install?

A typical new-construction home in Dallas takes two to four working days to roof, depending on roof size and complexity. Simple roofs on a detached garage or pool house can be done in a day. Large custom homes with multiple dormers, valleys, and steep pitches can take up to a week. Weather plays a role too: Dallas springs bring the rain, and we don’t install shingles on a wet deck. We’ll give you a realistic timeline when we walk your site.

Should I choose a shingle roof or metal for new construction in Dallas?

That depends on your budget and your long-term plans, but in the Dallas market, most new homes get architectural shingle roofs installed for $9,500 to $17,000. Shingle roofs handle North Texas hail and heat well when installed correctly, and they’re much more affordable than metal, which can run two to three times the price of shingles. Metal can make sense for a steep roof or a structure where longevity is the primary concern, but for most Dallas new builds, a high-quality architectural shingle from brands like Atlas, IKO, or Tamko is the right call.

Can Mercer Roofing work with my general contractor on the schedule?

Yes, absolutely. We work with general contractors and builders throughout Dallas, including in neighborhoods like Lakewood, Preston Hollow, Bluffview, and the fast-growing suburbs to the north like Frisco and Celina. We coordinate our portion of the schedule so the roof goes on at the right point in the build sequence: after the decking is up, before the siding and brick go on. If your GC has questions about our process or pricing, they can call (432) 302-5605 directly and talk to a live person.

Is it cheaper to have a roofer do new construction versus a reroof?

Generally, new construction roofing in Dallas is less expensive than a reroof of the same size because there’s no tear-off, no dump fees, and no decking repair. The new decking is clean, so we go straight to underlayment and shingles. For a 2,000-square-foot roof, a new-construction shingle install might run $10,000 to $15,000, while a full reroof of the same size, including tear-off and disposal, often runs $12,000 to $18,000. But the bigger advantage on new construction is that everything goes in right the first time, with a written guarantee behind it.
