What makes Key Biscayne different from every other roofing market in Florida? It’s an island. You’re surrounded by the Atlantic on one side and Biscayne Bay on the other. Salt spray hits your roof from two directions, and every hurricane that crosses the Gulf Stream has a clean shot at your house. We plan every roof on Key Biscayne for that reality, not for a generic Florida codebook.
Why Winslow Windows & Doors Is Key Biscayne’s Preferred Shingle, Tile & Metal Roofing Company
Ed Winslow founded this business in 2011, and his name is on every job we do on Key Biscayne. Homeowners along Crandon Boulevard and in the neighborhoods off Harbor Drive and West McIntyre Street call us because we answer the phone with a live person, every time. No call center, no ticket number, no voicemail loop at 2 a.m. during a storm scare.
We are licensed, insured, and our published address and license number are on every estimate we hand you. Every technician who walks onto your Key Biscayne property is background-checked and in uniform. Before our truck pulls up, you’ll know exactly who is at your door.
We also do the work correctly the first time, because on a barrier island there is no second chance when a storm is 72 hours out. That’s the standard behind our Done Right Promise. If it’s not done right, we make it right. That promise covers roof work on Key Biscayne and has since day one.
We understand the difference between a $12,000 shingle roof that meets minimal Florida code and a $19,000 shingle roof that meets Miami-Dade HVHZ and actually keeps its shingles in a Category 3. The first one passes a fast inspection. The second one survives.
Our Shingle, Tile & Metal Roofing Services in Key Biscayne
Our Shingle, Tile & Metal Roofing crews handle everything from full tear-offs on 1960s-era Key Biscayne single-family homes to tile roof replacements on mid-rise condominium buildings along Crandon Boulevard. Four sub-services matter most here:
Shingle Roof Replacement
The most common roof type on older Key Biscayne homes is architectural asphalt shingle. It’s affordable, and when we install it on Key Biscayne we use Miami-Dade NOA-approved shingles with six nails per tab, not the four nails you’ll see on mainland jobs. Wind uplift on a barrier island is a different animal. Many shingle roofs we replace on Key Biscayne are only 10-12 years old but have already lost shingle tabs at the eaves because the original installer used non-NOA underlayment or skipped the peel-and-stick starter strip at the perimeter.

Concrete and Clay Tile Roofing
Tile roofs look right on Key Biscayne, and concrete tile is still one of the most hurricane-resistant roof coverings available. But tile is only as good as the underlayment beneath it. We strip old tile roofs down to the deck, replace rotted plywood, and install a self-adhered HVHZ-compliant underlayment before laying new Miami-Dade NOA-approved tile. That’s the difference between a tile roof that lasts 40 years on Key Biscayne and one that starts leaking at the valley in year six.

Metal Roofing
Standing-seam metal is gaining popularity on Key Biscayne for a simple reason: it shrugs off salt spray better than any other roofing material, provided you use the right fasteners. The steel panels are not the weak point. The screws and flashing are. On Key Biscayne we spec stainless and marine-grade fasteners on every metal roof, because standard galvanized fasteners corrode through in five to seven years here. A metal roof on Key Biscayne with the right fasteners will outlast every shingle roof on the island.

Roof Repair and Re-Flashing
If your Key Biscayne roof is leaking around a vent, skylight, or HVAC curb, the problem is almost always the penetration flashing. Salt spray eats standard aluminum flashing at the seams, and wind-driven rain finds the gaps. We re-flash roof penetrations with marine-grade stainless steel and replace failed pipe boots with silicone units rated for HVHZ exposure. We also handle wind-uplift repairs on tile roofs where tile tabs have loosened at eaves and hips.

Trusted Brands We Service in Key Biscayne
We install and service roofing from brands that actually hold Miami-Dade NOA product approvals, which is the document that matters on Key Biscayne. Our lineup includes systems from PGT and CGI for skylight and roof-related glazing work, and we are authorized installers for eight premium brands across our window, door, and roof envelope work. For Key Biscayne customers we keep a local stock of marine-grade flashings, stainless fasteners, and high-temp underlayment so we are not waiting on a distributor in Doral when your roof is open. Most materials for Key Biscayne jobs are staged within 48 hours.
Common Shingle, Tile & Metal Roofing Problems We See in Key Biscayne Homes
- Salt-corroded valley metal and flashings. The Atlantic and Biscayne Bay conspire against standard galvanized roof metal. We regularly replace valley metal on Key Biscayne homes that is perforated with rust after only five or six years, well short of the 15-20 years the same metal would last in Kendall or Palmetto Bay.
- Non-NOA shingle and tile systems failing wind-uplift. Some of the original 1960s-1980s roofs on Key Biscayne homes were installed before Miami-Dade required NOA product approvals. After one or two hurricane seasons, shingle tabs lift, tiles crack at the nose, and insurers send non-renewal letters.
- Wind-driven saltwater intrusion at penetrations. Even a Category 1 storm can push saltwater through a poorly sealed pipe boot or exhaust vent on a Key Biscayne roof. We see rotted plywood decking and moisture-stained drywall around skylights and HVAC curbs on condos along Crandon Boulevard after almost every named storm.
- Premature tile failure due to failed underlayment. The tile itself often looks fine, but the felt or synthetic underlayment beneath it has deteriorated from heat and humidity. By the time you see a water stain on the ceiling of a Key Biscayne condo, the underlayment has been shot for months and the deck is wet.
Pricing for Shingle, Tile & Metal Roofing in Key Biscayne, FL
Key Biscayne roofing costs run higher than mainland Miami-Dade for two reasons: the required NOA-rated materials cost more, and the labor for HVHZ installation details (peel-and-stick underlayment, six-nail patterns, stainless flashings, secondary water barrier) adds meaningful hours. Here are honest ranges for Key Biscayne:
- Shingle roof replacement: $14,000-$28,000 for a typical 2,000-3,000 sq ft home, including tear-off, deck repair, NOA underlayment, and architectural shingles
- Concrete tile roof replacement: $22,000-$55,000 depending on tile profile, deck condition, and roof complexity
- Standing-seam metal roof: $18,000-$40,000 for residential; larger commercial or condo scope runs higher
- Roof repair and re-flashing: $750-$3,500 depending on scope; we offer $40 off any repair over $200

What Shingle, Tile & Metal Roofing Costs in Key Biscayne
Your price moves with four variables: the square footage of the roof, the number of penetrations (vents, skylights, curbs), the condition of the plywood deck, and whether you choose shingle, tile, or metal. On Key Biscayne there’s a fifth variable: whether the existing roof already meets Miami-Dade HVHZ and just needs replacement, or whether we have to correct an older installation that was never code-compliant to begin with. The second scenario adds cost because we strip everything to the deck and rebuild the roof assembly correctly.
For whole-home packages, figure $14,000 on the low end for a smaller single-story home with a simple roof plane and architectural shingles, up to $55,000+ for a large waterfront home with a complex tile roof, multiple valleys, and deck replacement. Large custom metal roofs with standing-seam profiles and hidden fasteners can exceed $40,000 on Key Biscayne. Our free in-home measure takes about an hour, and we hand you a written quote before we leave.
What the Miami-Dade HVHZ Code Actually Requires on Key Biscayne
Key Biscayne sits inside Miami-Dade County’s High Velocity Hurricane Zone, which is the strictest wind-load code in the United States. It’s not a suggestion. It’s a permit condition. Every shingle, tile, or metal roof we install on Key Biscayne must carry a Miami-Dade Notice of Acceptance (NOA), which is a product approval that verifies the entire roof assembly, not just the top layer, was tested for wind uplift and water intrusion at design pressures specific to your building’s height and exposure.
What does that mean in plain English? A compliant Key Biscayne roof includes a secondary water barrier installed over the deck seams, a self-adhered or mechanically attached underlayment rated for HVHZ, fasteners sized and spaced per the NOA, and a perimeter attachment detail that resists suction at eaves and rakes. The design pressure on a water-facing Key Biscayne roof is not a single number; it is calculated per building based on the mean roof height, the exposure category (D, because you are on open water), and the enclosure classification of the home. We submit that calculation with every permit application.
Cheap roofing quotes on Key Biscayne usually omit the self-adhered underlayment, use non-NOA tile or shingles, and skip the six-nail shingle pattern or the enhanced perimeter fastening. The roof may still pass a quick visual inspection, but it will not survive a sustained wind event, and your insurer will know the difference when you file a claim. You are not buying shingles. You are buying a roof assembly that proves itself in a storm.
A recent job on a mid-rise condo along Crandon Boulevard tells the story. We replaced a flat tile roof that had been installed just eight years prior with non-NOA-rated underlayment. The salt-laden wind had eaten through the valley metal and lifted tiles at the eaves. Our crew stripped to the deck, installed a self-adhered HVHZ-compliant underlayment, re-flashed all penetrations with marine-grade stainless, and set new Miami-Dade NOA-approved concrete tile, verified by a county inspector before final sign-off. That roof will still be on that building in 2060.
Florida Pays You Back
Owning a home on Key Biscayne means paying Florida-sized insurance premiums, and the state offers some help. The My Safe Florida Home program provides matching grants up to $10,000 for qualifying wind-mitigation upgrades. Impact-rated windows and doors are exempt from Florida sales tax. The federal 25C energy credit covers 30% of product cost, up to $600 per year, on qualifying energy-efficient units. And after a wind-mitigation inspection, which costs roughly $75-$150, Key Biscayne homeowners often see their windstorm premium drop by about 25% on the wind portion of the policy. Programs and carriers set the final numbers, so we don’t promise a specific dollar figure, but we document every NOA number, design pressure calculation, and installation detail so your inspection comes back clean.
Impact Windows vs. Hurricane Shutters: What Key Biscayne Homeowners Ask Us
Since we also install impact windows and doors in the HVHZ, Key Biscayne homeowners often ask whether they should just keep their old windows and add hurricane shutters instead. Shutters are cheaper up front. But they require someone to be home to deploy them, they don’t stop salt-air corrosion of the frames behind them, and they don’t reduce your energy bill or sound transmission the rest of the year. Impact-rated windows are permanent protection, no panels to hang, no storage, no scramble at the last minute. On a barrier island where evacuations happen and time gets short, permanent protection is worth the difference. Either choice works, but we almost never see a Key Biscayne homeowner go back to shutters after living with impact windows for one season.

FAQs - Shingle, Tile & Metal Roofing in Key Biscayne
Yes. Every shingle, tile, and metal roofing system installed on Key Biscayne must carry a current Miami-Dade NOA. That approval covers the entire roof assembly underlayment, fasteners, and top covering together, tested as a system. A product with only Florida Building Code approval is not sufficient inside the HVHZ. We pull permits and pass inspections with NOA documentation for every Key Biscayne roof we touch. Call (904) 478-8983 to ask about your roof’s current NOA status.
There is no single wind speed for all of Key Biscayne. The design wind speed depends on your building’s height, exposure, and location on the island, with water-facing elevations on the Atlantic or Biscayne Bay carrying the highest pressures. Roofs near Crandon Boulevard’s lower elevations typically see design pressures lower than a 15-story condo on the beach, but every Key Biscayne roof must meet Miami-Dade HVHZ standards, which far exceed typical inland Florida codes. Our permit filings include the exact design pressure for your home.
Salt spray. Key Biscayne is surrounded by open saltwater, and wind carries atomized salt onto your roof every single day. That salt corrodes flashings, fasteners, and valley metal years ahead of mainland coastal schedules. A tile roof in Coral Gables may go 20 years before the valley metal rusts through. On Key Biscayne we see the same failure in 5-7 years when non-marine-grade metal was used. The fix is marine-grade stainless flashings and fasteners, which we spec on every tile roof we install on Key Biscayne.
In many cases, yes. Insurers in Miami-Dade County apply wind-mitigation credits when a roof meets current HVHZ standards and the work is documented with a wind-mitigation inspection. We cannot promise a specific percentage because each carrier sets its own rate tables, but we have seen Key Biscayne homeowners reduce their windstorm premium by roughly 25% on the wind portion after a documented HVHZ roof replacement. We provide every NOA number, product approval, and installation detail your inspector needs.
No. Miami-Dade County will not issue a roofing permit on Key Biscayne for a system that lacks a current NOA. Even if a contractor offered to do it, the roof would fail inspection, and your condo association would be on the hook for the full replacement cost. Non-NOA installations also give insurers grounds to deny future wind claims. The money you save on a non-NOA roof evaporates the first time your association gets a non-renewal notice or a claim denial. Do it once, do it to code. Call (904) 478-8983 for an honest quote that meets Miami-Dade standards.
