New Construction in Miami, FL

New Construction in Miami, FL

New construction roofing in Miami means putting a brand-new roof on a newly built home, an addition, or a full teardown rebuild. Most new-construction roofs in Miami run between $14,000 and $32,000 depending on square footage, pitch, and material choice, and the work typically takes 3 to 7 days once the roof deck is ready. Mercer Roofing Co Miami handles new-construction roofing from the first sheet of decking to the final ridge cap, and you can reach us at (850) 753-2996 for a written estimate before any work starts. If you’re in the planning phase of a build, our Roof Replacement & Installation in Miami page covers the full scope of what goes into a roof project here.

Building new in Miami is not the same as building new in Tampa or Orlando. The wind loads are higher, the rain comes in sideways during summer storms, and the humidity never really lets up. That changes what goes under the shingles, how the decking is fastened, and which materials make sense. We’ve roofed new construction from Kendall to Aventura, and we build every roof to Miami-Dade County code from the first nail. Grant Whitlock has been running roof projects in this market since 2000, and the standards we follow today were shaped by every hurricane season since.

Key Takeaways

• New-construction roofing in Miami typically costs $14,000 – $32,000 for a single-family home, depending on size, pitch, and materials.
• Miami-Dade County has stricter wind-load and underlayment requirements than most of Florida, and your roof must be inspected at multiple stages.
• You get a written price before any work begins, and every installation is backed by the 365-Day Done Right Promise.
• Every Mercer Roofing Co Miami technician is background-checked, identity-verified, and arrives with a photo ID badge.

When You Need New Construction Roofing

New-construction roofing is not a repair scenario. It’s the roof that goes on when the framing is fresh, the decking is bare, and the building inspector is waiting on your roofer before they’ll sign off. Here are the situations where Mercer Roofing Co Miami steps in:

• You’re building a custom home from the ground up. The roof is one of the first major milestones after framing, and it has to be right before drywall can go in. We work directly with your GC or builder to keep the schedule moving.
• You’re adding a second story or a full addition. The new section needs roof decking, underlayment, and a tie-in to the existing roof that won’t leak where old meets new. That tie-in is where we see the most problems on additions in neighborhoods like Coral Gables and Pinecrest.
• The existing roof was torn off to the deck. Some teardown rebuilds in Miami keep the original block walls but replace everything above them. Your roof starts fresh, and code requires it to meet current wind standards, not the standards from when the house was first built.
• You’re converting a flat roof to a pitched roof. This is common in older Miami neighborhoods like Shenandoah and Silver Bluff, where flat roofs have held water for decades. A new pitched roof changes drainage, curb appeal, and resale value in one project.
• You’re building a detached structure. A garage, guest house, or pool cabana still needs a roof that meets Miami-Dade wind code. We do a lot of these smaller new-construction roofs in the summer, when homeowners are already thinking about storm season.
• Your builder’s roofer can’t pass inspection. This happens more than people expect. Failed inspections, missing documentation, or materials that don’t meet county requirements. We re-do it right, and we document everything.

Our New Construction Roofing Process

New-construction roofing in Miami has to move in step with the rest of the build. Our process is built around the inspection calendar, not against it.

1. Site walk and deck inspection. Before we quote anything, we walk the roof deck. We check the sheathing fasteners, the truss spacing, and the condition of the framing. If the decking isn’t right, the best shingles in the world won’t matter. This walk gives us the exact measurements for a written price.
2. Written estimate and material selection. You get a line-item price in writing. We’ll talk through the material options that make sense for your build. On new construction in Miami, we often recommend self-adhered underlayment in the valleys and eaves because of how wind-driven rain behaves here. You’ll see the exact brand, the exact product, and the exact cost before you sign anything.
3. Scheduling around your build. New-construction roofs are time-sensitive. We coordinate with your builder or GC to set the install dates once the deck passes framing inspection. We show up when we say we will, and the crew is uniformed and badged. You’ll know the name and face of the technician leading the job before they arrive.
4. Underlayment, flashing, and penetrations. This is the part of the roof you’ll never see, and it’s the part that matters most in Miami. We install the underlayment, we flash every pipe boot, vent, and valley, and we make sure the fasteners are driven to the right depth. Miami-Dade inspectors look hard at flashing and fastening, and so do we.
5. Shingle installation and edge detailing. We install the shingles to manufacturer spec for the wind zone you’re in. This matters for your roof warranty and your insurance. We use brands like Atlas, IKO, and Tamko, and we install them the way the manufacturer requires, because that’s the only way the warranty actually holds up.
6. Final walkthrough with you and your builder. You and your builder get a walkthrough before we call the job done. We point out the flashing details, show you the workmanship, and hand you the written guarantee for the installation. The 365-Day Done Right Promise is in writing: if something is not right within a year, we make it right.

New Construction Pricing in Miami

New-construction roofing in Miami is priced by the square, and the range is real: most single-family new-construction roofs we install run between $14,000 and $32,000. Here’s what shapes that number:

Line Item	Typical Range in Miami
Roof decking (if not already installed)	$3,500 – $8,000
Underlayment (synthetic, Miami-Dade approved)	$1,200 – $3,500
Architectural shingles (installed)	$8,000 – $18,000
Flashing, vents, and penetrations	$1,500 – $4,000
Permits and inspections	$400 – $1,200

That’s a real range, not a teaser number. A 1,800-square-foot ranch in Westchester with a simple 5:12 pitch and architectural shingles will sit at the lower end. A two-story custom in Coconut Grove with a steep pitch, multiple valleys, and impact-rated Atlas shingles will push toward the top. Metal, tile, and standing seam all cost more, and we’ll give you a straight answer on where the value is for your specific build. Call (850) 753-2996 and we’ll come out, walk the site, and put a written number in your hand. The estimate is free, and the price we quote is the price you pay.

What Miami Code Demands That Other Florida Cities Don’t

Since Hurricane Andrew, Miami-Dade County has had the strictest building code in the state, and roofing is at the top of the list. If you’re new to building here, this is not the place to wing it.

High-velocity hurricane zone (HVHZ) requirements. Most of Miami sits in a high-velocity hurricane zone. That means your roof assembly, not just your shingles, has to be rated for wind uplift and debris impact. Underlayment has to meet specific tear and nail-seal standards. The inspector will check it.

Self-adhered underlayment at eaves and valleys. Miami-Dade requires self-adhered underlayment in critical areas of the roof. That’s not an upsell in Miami; that’s the baseline. If a roofer quotes you a price that’s several thousand dollars lower than everyone else, ask them what underlayment they’re installing and whether it meets current Miami-Dade code. We install code-compliant underlayment on every new-construction roof, and we’ll show you the product before it goes down.

Fastener schedule and uplift ratings. Miami-Dade inspectors require a specific nail pattern and fastener type based on your roof’s uplift zone. Corner zones and eave zones get more fasteners. This is not negotiable, and it’s not something we shortcut. Every inspection we go through is one our crews have passed hundreds of times.

Materials We Recommend for Miami New Construction

We install and repair with manufacturer-recognized brands, and on new construction in Miami, three stand out for how they handle heat, humidity, and wind.

Atlas shingles. Atlas makes architectural shingles that hold up to intense UV exposure, which matters in a city where the sun pounds a roof almost every day of the year. Their Scotchgard-protected lines also resist the algae staining that turns Miami roofs black within a few years.

IKO shingles. IKO’s architectural lines come with strong wind ratings and are a good middle-ground choice for homeowners who want a quality roof without the highest price tag. We’ve put IKO roofs on new construction in Kendall and Hialeah and they’ve held up through multiple summers.

Tamko shingles. Tamko offers some of the better color variety if you’re building a home with a specific architectural style you want to match. Their high-definition architectural lines are a solid choice for custom builds where looks matter as much as performance.

We’ll talk about what fits your home, your budget, and the look you’re after. You won’t get a hard sell on a brand we prefer; you’ll get a straight recommendation based on your roof.

Why Homeowners Choose Mercer Roofing Co Miami

Most roofing companies in Miami can install a roof. What’s harder to find is a company that tells you exactly who is coming to your home before they arrive. That’s the standard we operate under, and it’s not a marketing line.

You know who’s coming before they ring the bell. Every Mercer Roofing Co Miami technician has been background-checked and identity-verified under the Threshold Verified standard. Before we arrive, we send you the name and photo of the technician who will be at your door. When they show up, they’ll be in a clean, marked uniform and they’ll present a photo ID badge. If you have children at home, if you’re often home alone, or if you just don’t like the idea of a stranger walking your property without proof of who they are, this is the differentiator that matters.

Every price is in writing before work starts. No verbal estimates. No handshake numbers. No “we’ll see how it goes” pricing. You get a written price, and the invoice matches the estimate. That’s how Grant Whitlock has run jobs from the start, and it’s how every Mercer Roofing Co Miami project goes.

The 365-Day Done Right Promise. If any part of your new-construction roof installation is not done right within a year, we make it right. The promise is in writing, and it’s included with every job. There’s no fine print that excludes the things that actually go wrong.

A live person answers the phone, 24/7. Call (850) 753-2996 at any hour and a human being picks up. Not a voicemail tree, not a callback request. That matters when a storm is coming and your roof isn’t done.

FAQs – New Construction

How much does new construction roofing cost in Miami?

New construction roofing in Miami typically costs between $14,000 and $32,000 for a single-family home, with the final number set by square footage, roof pitch, material choice, and code requirements. A simple ranch with architectural shingles lands near the lower end; a steep custom build with impact-rated materials pushes higher. Call (850) 753-2996 for a written quote on your specific project, free of charge.

Can you start new construction roofing right away?

In most cases we can schedule a site walk within a few days of your call and begin work as soon as the roof deck passes framing inspection. New-construction roofing is time-sensitive, and we coordinate with your builder to keep the project moving. Call (850) 753-2996 to check our current availability.

Is a new-construction roof different from a roof replacement?

Yes. A roof replacement goes over an existing house, which means the old roof has to be torn off and the deck inspected for damage. New construction roofing starts with fresh framing and bare decking, so the process is faster in the early stages but requires tighter coordination with building inspectors. Both are work we do regularly, and the pricing model doesn’t change: you get a written price before anything starts.

What roofing materials should I use for new construction in Miami?

For most Miami new-construction homes, architectural asphalt shingles from Atlas, IKO, or Tamko offer the best balance of cost, wind resistance, and longevity. We’re happy to quote tile, metal, and standing seam as well, but shingles remain the most common choice for new builds here. Call (850) 753-2996 and we’ll talk through the options for your specific roof.

Do you handle the permits and inspections for new-construction roofing?

Yes. We pull the permits, we schedule the inspections, and we walk the job through every stage of Miami-Dade’s approval process. You won’t be chasing paperwork or calling the building department. That’s part of what you’re paying for, and we treat it as core to the job, not an add-on.
