Fast, Reliable Roof Installation Across Miami Gardens
Roof installation in Miami Gardens typically runs $8,500 to $24,000 depending on the system you choose, the size of your roof, and how much tear-off is involved. Most full replacements on the concrete block ranches that dominate Miami Gardens take 3 to 7 working days once materials are on site. If you’re weighing options, call (850) 753-2996 and we’ll give you a written line-item price before any work starts, not after. Our roofing company in Miami Gardens knows these streets, from the neighborhoods off NW 27th Avenue to the newer subdivisions near Hard Rock Stadium.
Grant Whitlock leads our team, and he’s built Mercer Roofing Co Miami around one idea: you should know exactly who’s walking up your driveway and exactly what the job will cost before a single nail goes in. That’s why every technician’s name and photo is sent to you before arrival, and every technician badges in with a photo ID at your door.
Why Mercer Roofing Co Miami Is Miami Gardens’s Preferred Roof Installation Company
Miami Gardens homeowners call us because we treat the stranger-at-the-door problem as seriously as the roof problem. Before any visit, you’ll receive the name and photo of the technician coming to your home. When they arrive, they’ll be in a clean Mercer uniform with a photo ID badge, background-checked and identity-verified under the Threshold Verified standard. This is not a courtesy, it’s how we operate on every single job, and it matters most for homeowners who are often home alone, parents with young children, and older residents who want proof of who’s at the door.
Every Mercer Roofing Co Miami project begins with a written price. That’s the pricing before work starts, in writing, with no surprises on the back end. Every installation is covered by our 365-Day Done Right Promise: if the work isn’t right within a year, we make it right. Written guarantee, free second visit if a repair fails. No fine print gymnastics.
We’re part of the Threshold Group family, founded in 2000, and this Miami location is independently owned and operated. Dispatch and scheduling are coordinated from our South Florida office, and crews serve Miami Gardens locally. When you call, a live person answers, 24/7. Not a voicemail. Not a callback form. A human being who can schedule your free estimate.

TPO Roofing Installation in Miami Gardens
TPO Roofing Installation in Miami Gardens is the most common full replacement we do on the city’s original flat-roofed ranches. TPO is a heat-welded single-ply membrane that reflects heat, resists ponding water, and carries high wind uplift ratings, which is exactly what Miami Gardens’ low-slope roofs need during afternoon thunderstorms and hurricane season. A full TPO tear-off and installation on a 1,200 to 1,800 square foot Miami Gardens ranch typically runs $9,500 to $16,500, including tear-off of old built-up roofing, decking repair where needed, new underlayment, and the membrane system.
Tear-Off and Decking Inspection
Many Miami Gardens flat roofs, especially the 1950s and 1960s homes west of NW 27th Avenue, have two or three layers of old gravel-surfaced built-up roofing that has been patched repeatedly. We tear off down to the decking every time, because you cannot properly install a TPO system over saturated or decaying layers. We inspect the deck and replace water-damaged sections before the membrane goes down.
Wind Uplift and Code Compliance
Miami-Dade County operates under High Velocity Hurricane Zone, or HVHZ, codes, and that changes how we fasten and weld the TPO system. We secure the membrane with perimeter fastening and plates, then heat-weld the seams so the roof acts as one continuous surface. If your home needs to pass a wind mitigation inspection, this is the system that gets you there.
Shingle Roof in Miami Gardens
Shingle Roof in Miami Gardens is the standard choice on the newer homes near Hard Rock Stadium and on larger properties where a pitched roof already exists or where homeowners want a traditional look. Dimensional asphalt shingles from Atlas, Tamko, or Boral give you class impact ratings and wind ratings that meet Miami-Dade’s HVHZ requirements when installed with the right underlayment and nail pattern. A shingle reroof in Miami Gardens typically runs $8,500 to $14,000 for an average 1,500 to 2,000 square foot home, including old shingle tear-off, new underlayment, drip edge, and ridge vent.
Re-roof vs. Re-cover on Miami Gardens Homes
If your Miami Gardens home already has one layer of shingles, you’ll likely need a full tear-off to comply with current Miami-Dade building codes. We don’t overlay new shingles on old ones here because the code won’t allow it and the warranty won’t hold. Tear-off also lets us find and repair deck rot around chimneys, valleys, and eaves before the new roof goes on.
The Right Underlayment for Florida Humidity
Miami Gardens’ tropical monsoon climate means heat and moisture are constant enemies under the shingles. We use synthetic underlayment with high perm ratings so trapped moisture can escape, and we seal penetrations and flashings with attention to the details that fail first. The shingle is only as good as what’s underneath it.
Trusted Brands We Service in Miami Gardens
Mercer Roofing Co Miami installs and services manufacturer-recognized shingle brands including Atlas, Tamko, and Boral, alongside GAF service in Miami Gardens and TPO systems built for South Florida’s HVHZ requirements. We keep common flashings, drip edge, and vent components stocked for Miami Gardens jobs, which means fewer delays when we’re mid-install and the weather turns. If you want a specific brand or color, we’ll order it and give you the written price before work begins, so there’s no guessing on the invoice.
Common Roof Installation Problems We See in Miami Gardens Homes
- Ponding water on low-slope built-up roofs: Miami Gardens’ frequent afternoon thunderstorms leave water sitting on flat roofs, and over time that water rots decking around penetrations and at scuppers. We address drainage and positive slope during the installation so water doesn’t just sit there.
- Wind uplift peeling patchwork layers: Hurricane season winds get under loosely adhered patched areas and lift old flashing at parapet walls and roof-to-wall intersections. You can’t fix this with another patch; the old layers need to come off for a full, code-compliant system.
- Multiple re-roofs exceeding structural load limits: Homes that have had two or three layers of built-up roofing added over the decades are carrying more weight than the concrete block walls were designed for. We’ve seen cracking near the roofline on these homes, and a full tear-off is the only way to bring the load back in line.
- Decking rot around penetrations and soffits: Pipe penetrations, vents, and scuppers are the first places water gets in on a Miami Gardens flat roof. When we open these up during a tear-off, we often find rotted plywood at the soffit and fascia that has been quietly failing for years.

AfterPricing for Roof Installation in Miami Gardens, FL
A TPO roof installation in Miami Gardens runs $9,500 to $16,500 for a typical 1,200 to 1,800 square foot ranch. A shingle roof runs $8,500 to $14,000 on most homes. What moves the price: the number of old roof layers we have to tear off, whether decking or fascia needs replacement, whether you have septic and well setbacks that limit equipment access, and the size of your roof. Homes west of NW 27th Avenue with multiple layers of old BUR usually land at the higher end because the tear-off is labor-intensive. Every estimate is written, line-item, and free. Call (850) 753-2996 and we’ll price your exact roof, not a guess.

FAQs About Roof Installation in Miami Gardens
If your flat roof has two or more layers of old built-up roofing, signs of ponding water, or interior staining near penetrations, you likely need a full tear-off. Another patch won’t fix decking rot underneath, and Miami-Dade HVHZ code won’t allow indefinite overlays. Call (850) 753-2996 and we’ll inspect it and give you a straight answer in writing.
Yes, roof replacements in Miami Gardens require a permit through Miami-Dade County, and acreage lots often have additional review for septic and well setbacks. We pull permits on every job and coordinate inspections, so you don’t have to navigate the county process alone.
Yes, TPO is the most common choice for Miami Gardens flat roofs because it’s heat-welded at the seams, resists ponding water, and carries high wind uplift ratings when installed to HVHZ standards. It won’t peel in hurricane winds the way layered patchwork does. We install it with perimeter fastening and welded seams, then back it with our 365-Day Done Right Promise.
Usually not, but setbacks do matter. Miami-Dade requires minimum distances between buildings and septic drain fields or wells, which can change where a detached garage can sit and how we stage equipment for the roof installation. We scope the site for setbacks before quoting so the price reflects real access and grade conditions, not surprises later.
Older concrete block ranches in Miami Gardens often carry multiple layers of gravel built-up roofing that must be torn off down to the decking, and that tear-off labor is a large portion of your cost. If the decking or fascia has rot, which is common after decades of Florida thunderstorms, you’ll see that added to the written quote. The good news: you’ll get an exact number before work starts, and the price won’t change mid-job.
