Full Roof Replacement in Miami, FL

Full Roof Replacement in Miami, FL

A full roof replacement in Miami means tearing off the old roofing system down to the decking and installing everything new: underlayment, flashing, shingles, and the ridge. It’s what a home needs when repairs would only buy a few more months. For most Miami homeowners, this runs between $9,800 and $24,000 depending on roof size, pitch, and the shingle brand you choose.

We’re Mercer Roofing Co Miami, and we’ve been replacing roofs in this city since 2000 as part of the Threshold Group family of home-service companies. Before you ever sign anything, you get a written price. Before our technician ever rings your bell, you get their name and photo. That’s how we work, and it’s the same on every full Roof Replacement & Installation in Miami job we take. If you’re weighing repair against replacement, call us at (850) 753-2996 and we’ll walk you through what we’re seeing on your roof, honestly.

Key Takeaways

• Full replacement in Miami typically costs $9,800 to $24,000, with most homes landing between $12,000 and $17,000.
• Miami’s wind, salt air, and wet-dry cycles shorten roof life compared to inland Florida, making full replacement common by year 18 to 22.
• Mercer Roofing Co Miami sends every technician’s name and photo before arrival, and every price in writing before work starts.
• The 365-Day Done Right Promise covers the full replacement: if it’s not right within a year, we make it right.
• Live people answer our phones 24/7 at (850) 753-2996.

When You Need Full Roof Replacement

Not every problem roof needs to be torn off. But in Miami, where afternoon thunderstorms hit hard and hurricane season runs half the year, the signs that replacement is the smarter call show up early. Here’s what pushes most Miami homeowners toward a full replacement:

• Shingle granule loss that’s left bald patches. Miami’s UV is brutal. If you’re seeing granules in your gutters after every rain and the shingles look shiny or bare, the protective layer is gone. In neighborhoods like Shenandoah and Coral Gate, where homes were built in the 1950s and 60s, we see this constantly.
• Water stains on ceilings or attic sheathing. A single leak can sometimes be patched. But if you’ve had two or more leaks in different spots within a year, your underlayment is likely failing across large sections. That’s not a repair situation.
• Roof age past 18 years. Even the best asphalt shingle on a Miami roof rarely makes it past 22 years. The heat, the salt air off Biscayne Bay, the humidity cycling through the attic – it all accelerates aging.
• Curling, cupping, or lifting shingles. When shingles start lifting at the edges, wind gets under them. In a tropical storm or hurricane, that’s how sections of roof peel off. If you’re seeing this on more than a third of the roof, replacement is cheaper than repeated repairs plus the risk.
• Sagging or soft decking. If you can see dips in your roofline, or if the decking feels spongy when walked on, moisture has been getting in for a while. This usually means replacing decking sections during the job, which is standard for full replacements in older Miami neighborhoods like Allapattah and Liberty City.
• Your insurance carrier or inspector flagged it. Many Miami homeowners find out they need a replacement when their insurer won’t renew the policy on a roof past a certain age. We’ve replaced roofs in Cutler Bay, Kendall, and Hialeah for exactly this reason.

Our Full Roof Replacement Process

Here’s how a full replacement with Mercer Roofing Co Miami goes, step by step:

1. You call, and a real person answers. No phone tree, no “leave a message.” We answer 24/7. You describe what’s going on with your roof, and we schedule an inspection.
2. You get the technician’s name and photo first. Before the visit, we send you the name and photo of the exact person who will arrive. On the day, they’re in a clean, marked uniform and they show you a photo ID badge at the door. Every Mercer technician is background-checked and identity-verified under the Threshold Verified standard, which each Threshold Group location is contractually held to.
3. The roof gets inspected, and you get a written price. We go up, check the shingles, flashing, valleys, penetrations, and decking. Then we sit down with you and write out a price. Not a range, not a guess. A written number for the full scope. No work starts without it.
4. We tear off and install. We remove everything to the decking, inspect what’s underneath, replace any rotted or damaged decking boards, then install new underlayment, flashing, and shingles. We work with manufacturer-recognized brands including GAF, CertainTeed, and Owens Corning, and can also quote IKO, Atlas, and Tamko depending on what you want and what your home needs.
5. We walk the roof with you. Before we call the job done, we take you through what was installed, where the flashing is, and what to look for in the years ahead. You shouldn’t have to guess what was done up there.
6. Your 365-Day Done Right Promise starts. The written guarantee that comes with the job covers the full replacement for a year. If something isn’t right, we come back and make it right at no charge.

Full Roof Replacement Pricing in Miami

We give real numbers because you deserve to know what to expect before you call. Here’s what full replacements cost in Miami, based on the jobs we’ve priced across the city:

Roof Size / Type	Typical Miami Price Range
Small home, 1,000 – 1,400 sq ft roof	$9,800 – $13,500
Mid-size home, 1,500 – 2,000 sq ft roof	$12,500 – $17,500
Large home, 2,200 – 3,000 sq ft roof	$16,000 – $24,000
Decking replacement (per sheet, if needed)	$85 – $125 per sheet
Flashing replacement (full perimeter)	$750 – $1,800

What moves the number? Roof pitch matters, and Miami has plenty of steep pitches in older neighborhoods. The steeper the roof, the more labor and safety equipment required. Decking condition is the other big one. If rain got through a failed section of underlayment, those boards come out and new ones go in, and that adds to the total. Shingle brand and grade also shift the price, and we’ll show you the difference in writing for each option.

Every quote includes the full tear-off, haul-away, underlayment, shingles, flashing, ridge, and the written 365-Day Done Right Promise. What you see on the quote is what you pay. Call (850) 753-2996 for a free estimate and we’ll send someone out to give you a real number.

Why Miami Roofs Wear Out Faster Than You’d Think

Miami isn’t like Orlando or Tampa when it comes to roofing. We deal with three things constantly:

• Salt air. Homes within a couple miles of Biscayne Bay or the ocean get salt spray on the roof year-round. It accelerates corrosion on flashing and fasteners, and it degrades asphalt shingles faster than inland moisture ever will. We see roofs in Brickell, Edgewater, and Morningside fail two to three years earlier than identical roofs in Westchester or Doral.
• Intense UV + afternoon downpours. The sun bakes the shingles all day, then a 3 p.m. storm drops an inch of rain in 40 minutes. That rapid heating and cooling cycles the materials hard. Shingles lose granules, underlayment bakes, and seams open up.
• Wind-driven rain. It’s not just the hurricanes. Miami gets frequent squalls with wind gusts hitting 50 mph in the summer. Rain driven sideways finds gaps that vertical rain never would. That’s why we’re specific about flashing details on every penetration: skylights, vents, chimneys, pipe boots.

When we replace a roof in Miami, we’re building for these conditions. Not just nailing down shingles and hoping.

What We Install: Shingles That Earn Their Keep in Miami

We install and repair roofs using shingle brands recognized by the manufacturers themselves. For most Miami homes, we recommend GAF, CertainTeed, or Owens Corning, which together cover the majority of what we install. But we also work with IKO, Atlas, and Tamko, and we’ll quote whichever fits your budget and your home’s wind-exposure needs.

For homeowners in coastal zones, we often discuss Atlas StormMaster or CertainTeed’s higher wind-rated lines. For homeowners watching the budget, IKO and Tamko have solid mid-tier options that still carry strong warranties. We don’t push one brand on every house. The right shingle depends on your roofline, your distance from the coast, and what you want to pay. We’ll lay out the options with the real price on each, in writing, before you commit.

Miami Permits and Code: What We Handle

Full roof replacements in Miami require a building permit, and the work has to meet Miami-Dade County’s High Velocity Hurricane Zone requirements. That means specific nailing patterns, specific underlayment, and specific flashing details. We pull the permit, schedule the inspections, and make sure the final job passes.

If you’ve ever had a contractor suggest skipping the permit to save a few hundred dollars, walk away. An unpermitted roof replacement creates problems when you sell the house, and it can void your insurance. We do it by the book, every time, in every Miami neighborhood we serve, from Coconut Grove to Little Havana to North Miami.

FAQs – Full Roof Replacement

How much does a full roof replacement cost in Miami?

In Miami, a full roof replacement typically costs between $9,800 and $24,000, with most mid-size homes landing between $12,000 and $17,000. Roof size, pitch, decking condition, and shingle brand are the biggest cost drivers. Call (850) 753-2996 for a free on-site estimate with a written price before any work starts.

Is it cheaper to repair or replace my roof?

If your roof is under 12 years old and the damage is in one area, repair is usually cheaper. If your roof is 18 years or older, or if you have multiple leaks, granule loss across large areas, or lifting shingles, replacement is often the better long-term value because repeated repairs add up fast. We’ll inspect and tell you straight which one makes sense, and we’ll put both numbers in writing.

How long does a full roof replacement take in Miami?

Most full replacements are completed in two to four days, depending on roof size, pitch, and how much decking needs replacing. Weather can stretch the schedule during Miami’s rainy season, and we’ll keep you updated if storms change the timeline. Our crews work clean and secure the roof every evening in case of overnight rain.

Can you replace my roof the same week I call?

We schedule inspections quickly, and depending on our current queue and permit timing, many Miami homeowners get their replacement started within one to two weeks of signing. Call (850) 753-2996 and we’ll give you a real timeline based on where we are right now.

Do you send someone I can verify at the door?

Yes. Before every visit, we send you the name and photo of the technician who will arrive. When they ring the bell, they’re in a clean, marked Mercer uniform and they show a photo ID badge. Every technician is background-checked and identity-verified under the Threshold Verified standard. You always know who you’re letting in.

What does your 365-Day Done Right Promise cover?

For a full year after your replacement, if anything we installed isn’t right, we come back and make it right at no cost to you. This includes repair visits if something fails. It’s a written guarantee, and it’s included with every job. You don’t have to ask for it, and you don’t pay extra.
