Tilehurst Roofing Miami provides residential and commercial roofing across Key Biscayne, from flat concrete condo roofs near the Rickenbacker Causeway to barrel-tile villas in the Village. Our crews know which materials survive here, and which ones don’t. Call (850) 613-1762 for a free estimate, and we’ll tell you the truth about your roof before we quote a single dollar.
Why Tilehurst Roofing Miami Is Key Biscayne’s Preferred Roofing Company
Greg Holloway leads our Key Biscayne crews, and he’s spent years watching coastal roofs fail early because someone inland specced the wrong hardware. That’s the difference you feel on the first visit. We show up with marine-grade fasteners in the truck, not a bucket of big-box galvanized. Homeowners across Key Biscayne, from Harbor Drive to Mashta Island, call us back for the same reason: we write the price before the work starts, and we put the guarantee in writing before the crew packs up.
As part of the Kingswell family of roofing companies, founded in 2000, we’re backed by a 365-Day Done Right Promise. If a repair fails inside the guarantee period, we return at no charge. A live person answers every call, 24 hours a day, 7 days a week. No voicemail, no callback queue. Our Roofing Company team knows Key Biscayne’s building codes, its wind-rating requirements, and its HOA expectations. That local knowledge keeps the job moving without surprises.
Styles & brands we work with






Commercial Roofing in Key Biscayne
Commercial Roofing on Key Biscayne means flat or low-slope membrane systems on condominium buildings, office structures, and mixed-use properties across the island. These roofs fight a three-front war: salt spray from the Atlantic, standing water after summer downpours, and relentless UV that bakes elastomeric coatings until they chalk. A typical commercial roof repair on Key Biscayne runs $1,800 – $4,500. Full recoat and membrane replacement on a midsize condo building generally lands between $28,000 and $75,000, depending on square footage, deck condition, and the coating system specified.
Membrane Seam Failures We Find Here
We open more seams on Key Biscayne commercial roofs than anywhere else in our Miami service area. Tropical-storm-driven rain rides horizontally into unsealed penetrations, then delaminates the membrane from the deck. The repair isn’t just re-gluing the seam: it’s stripping back, drying the substrate, and re-sealing every penetration with polyurethane caulk rated for marine exposure.
When Recoating Beats Replacing
A concrete deck that hasn’t cracked structurally can often take a high-solids silicone or polyurethane coating instead of a full tear-off. The catch on Key Biscayne is the prep. Salt film has to be power-washed off completely, or the new coating peels within two seasons. We budget for that prep because skipping it is why cheap recoat jobs fail here in 24 months.
Metal Roof Installation in Key Biscayne
Metal Roof Installation on Key Biscayne is a different animal than metal roofing inland. On Harbor Drive, we replaced corroded flashing and decking fasteners on a 1980s flat concrete roof where the original galvanized drip edge had rusted through. We stripped to the deck, installed a self-adhered ice and water shield over sealed penetrations, and set marine-grade 316 stainless flashing. The homeowner had already lost two ridge vents to salt pitting in six years. A full standing-seam metal roof on Key Biscayne typically runs $18 – $32 per square foot installed, with the upper end reflecting marine-grade alloys and heavier-gauge panels rated for 150-mph uplift.
Fasteners Before Panels
The panel is never the weak point; the stainless screws and clips are. We specify marine-grade 316 stainless fasteners on every metal installation near the water. Standard 304 stainless, which works fine in Coral Gables, pits within three to five years on Key Biscayne. The upgrade adds roughly $300 – $600 to an average roof, and it’s the cheapest insurance you’ll ever buy on this island.
Coastal Trim and Flashing Details
Eave trim, ridge cap, and pipe boots fail before the field panels ever do. We cut all trim from the same marine-grade alloy as the panels and seal every lap joint with polyurethane caulk. Galvanized trim can rust through on Key Biscayne in under four years. We won’t install it here, even when a homeowner asks, because we know it’ll come back as a warranty claim.
Trusted Brands We Service in Key Biscayne
We install and repair roofing systems from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. On Key Biscayne, we lean on IKO and Boral for tile profiles that match 1970s and 1980s originals, and Atlas for wind-rated asphalt shingle lines that meet Miami-Dade requirements. We keep common Key Biscayne replacement parts in our Miami warehouse, so a cracked Boral tile or a rusted Atlas ridge vent doesn’t leave you waiting on a three-week factory order. Our Roofing Company in Key Biscayne crews stock fasteners, caulk, and touch-up coatings specifically for this salt-air environment.

AfterCommon Roofing Company Problems We See in Key Biscayne Homes
- Rusted galvanized flashings and fasteners. Salt-laden wind from the Atlantic corrodes standard galvanized hardware in three to five years. We spec hot-dip or marine-grade 316 stainless on every replacement, because the inland version simply doesn’t last here.
- Delaminating flat-roof membrane seams. Wind-driven rain pushes under unsealed penetrations and peels membrane seams off concrete decks. Polyurethane-sealed penetrations and self-adhered underlayment stop the water before it gets inside.
- Chalking elastomeric coatings. Intense solar exposure breaks down inexpensive coatings on flat concrete roofs within two to three years, leaving standing water to find every hairline crack. High-solids silicone resists UV and salt far longer.
- Rusted ridge vents on mid-rise condos. Even ‘stainless’ steel vents pit out within five years near the water. We replace them with marine-grade alloy vents and seal the bases with polyurethane caulk so the fasteners aren’t the failure point.
Pricing for Roofing Company in Key Biscayne, FL
Roof repair on Key Biscayne generally runs $450 – $1,800, with most asphalt shingle repairs landing between $600 and $1,200. A tile roof repair starts closer to $500 for a few cracked tiles and climbs to $2,500+ when the underlayment underneath has gone. Full asphalt shingle replacement here runs $7 – $12 per square foot installed; tile replacement runs $14 – $25 per square foot; flat concrete recoating runs $6 – $10 per square foot depending on coating type and prep. Coastal-spec materials add 10 – 18% to an inland quote. That premium buys you marine-grade fasteners, sealed penetrations, and a system that doesn’t rust out in five years. Call (850) 613-1762 for a written, line-item price before any work starts.

FAQs About Roofing Company in Key Biscayne
We specify marine-grade 316 stainless steel fasteners on every Roof Replacement - Key Biscayne within a mile of the water. Standard galvanized or 304 stainless, which works fine inland, pits and rusts through within three to five years on Key Biscayne. The upgrade costs a few hundred dollars and is non-negotiable on our coastal jobs. Call (850) 613-1762 and we’ll show you the difference on a sample board.
Because the prep work doubles. Salt film has to be power-washed off the concrete deck completely, and every penetration has to be stripped and re-sealed with polyurethane caulk before the new coating goes down. An inland flat roof might skip that step; on Key Biscayne, skipping it means the coating peels within two seasons. The prep runs $0.80 – $1.50 per square foot extra and it’s the only way a recoat survives here.
We remove the old vent, grind any surface rust around the opening, and install a marine-grade alloy vent with 316 stainless fasteners. The base gets sealed with polyurethane caulk, not standard roofing cement. Standard ‘stainless’ vents from big-box stores pit out within five years here. Our replacement vents are rated for coastal exposure and outlast the roof around them.
Yes. We install a self-adhered ice and water shield over sealed penetrations on every replacement and most repairs on Key Biscayne. Standard felt underlayment doesn’t stop the horizontal rain a tropical storm drives under the roof covering. The upgrade runs $0.40 – $0.80 per square foot and is required by Miami-Dade code for high-wind zones to begin with.
We recommend a two-part polyurethane joint sealer rated for marine exposure, applied over a clean, dry joint after any roofing work below is complete. Standard polymeric sand washes out of rooftop terrace joints within a year on Key Biscayne. The two-part sealer runs about $2.50 – $4.00 per linear foot installed, and we time it with the roofing crew so the terrace isn’t torn up twice.
