Why Tilehurst Roofing Is Key Biscayne’s Preferred Roof Replacement Company

Homeowners on Key Biscayne have good reason to be skeptical of roofers. The island’s permitting process and NOA paperwork are unforgiving, and a contractor who mostly works the mainland often has no idea what Key Biscayne inspectors actually check in the field. We do. Our crews work Key Biscayne regularly and know that Miami-Dade building inspectors here routinely verify fastener type and spacing on the nail fin during permit inspections. That’s not a surprise to us; it’s baked into every quote we write.

Tilehurst Roofing is a Kingswell family company, founded in 2000, led locally by Greg Holloway. We answer the phone with a live person 24 hours a day, 7 days a week, including evenings and weekends. We arrive in the window we give you. And every roofing job starts with a written price in your hands before a single nail is driven. If something isn’t right within a full year of the job, our 365-Day Done Right Promise means we come back and make it right. No negotiation, no change orders at the door. Written guarantee on every replacement, delivered before the crew leaves.

Asphalt Shingle Roof Replacement in Key Biscayne

Asphalt Shingle Roof Replacement in Key Biscayne means tearing off the old shingle layer, inspecting and often replacing the roof decking (the plywood or OSB sheet under the shingles), and installing a new shingle system with underlayment, drip edge, valley flashing, ridge cap, and stainless-steel ring-shank fasteners at NOA-specified spacing. Most full replacements here run $14,000-$26,000 for architectural shingles on a typical 2,000-3,500 square-foot home. A basic three-tab asphalt shingle runs $12,000-$18,000, but we rarely recommend it on the island.

Architectural Shingles: The Island Standard

Most Key Biscayne homes we replace get architectural shingles, sometimes called dimensional shingles. They’re thicker, rated higher for wind uplift, and last 5-10 years longer than three-tab. GAF architectural shingles rated to 130 mph are a common choice here, and they hold a Miami-Dade NOA, which means they can legally be installed in Key Biscayne. We also stock Atlas and CertainTeed architectural lines with active NOAs.

Roof Decking Replacement

The deck is the hidden layer underneath the shingles. On Key Biscayne, it’s often worse than the shingles look. Decades of bay-and-ocean salt spray accelerates oxidation on the fasteners holding the deck to the trusses, and rotted deck sections are common on post-Andrew homes. Miami-Dade code requires the deck to be sound before the underlayment goes down. We inspect every sheet, replace what’s failed, and include the decking work in your written price up front, not as an add-on later.

New Roof Installation in Key Biscayne

New Roof Installation in Key Biscayne applies to new construction, additions, or major renovations where there is no existing roof to remove. Most new construction here is either luxury single-family or low- and mid-rise condominium work with flat or low-slope membrane systems, not shingles. New shingle-roof installation on a house runs $16,000-$38,000 depending on square footage, pitch, and the manufacturer’s system specified. Flat membrane systems for condominium or commercial work run $12-$22 per square foot.

New Construction and Permits

New construction in Key Biscayne means the roofing submittal goes through the full Miami-Dade permit review process, including product approval documents for every component: underlayment, shingle, nail, drip edge, flashing, and ridge cap. The Village of Key Biscayne building department operates under Miami-Dade County code enforcement, and inspectors on the island are known for checking NOA numbers on site. You want a roofer who pulls the permit, lists the correct NOA numbers on the submittal, and passes the inspection without a return trip.

Flat Roofing for Condominium Towers

Key Biscayne has dozens of mid-rise condominium buildings along Crandon Boulevard and Ocean Drive, and nearly all of them have flat or very low-slope roofs. These are not shingle systems. They’re modified bitumen, TPO, or PVC membrane systems that require hot-air welding or torch work, not nailing. Tilehurst crews handle flat roofing replacements on Key Biscayne regularly, and we carry Boral and GAF commercial membrane lines with valid Miami-Dade NOAs.

Trusted Brands We Service in Key Biscayne

Key Biscayne homeowners get genuine material choice from us: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That’s seven manufacturers, every one with a product line certified for Miami-Dade’s NOA program. We don’t install whatever happens to be in the truck. If you want GAF architectural shingles with a 130 mph wind rating, we stock them locally and can have them on your roof within days. If you want Atlas or Tamko, same story. The product is chosen to fit the home and the exposure, not our inventory convenience.

Common Roof Replacement Problems We See in Key Biscayne Homes

• Oxidized galvanized fasteners. The bay and ocean spray attack ordinary hot-dipped galvanized nails and underlayment clips from both sides. We routinely find fasteners that have rusted to the point of losing grip years before the shingle warranty expires.
• Post-Andrew age wave. Homes rebuilt between 1993 and 1996 after Hurricane Andrew are now 28-30 years old. That’s the end of a shingle roof’s service life, and we’re seeing those homes fail in clusters across the island.
• Missing NOA documentation. A cheap mainland bid often skips the Miami-Dade NOA paperwork entirely. The roof may look fine, but it’s unpermitted, and an insurance carrier can refuse a storm claim because the product was never certified to be installed in Miami-Dade County.
• Loose drip edge and ridge cap. The drip edge (the metal strip along the roof’s edge that channels water into the gutter) and the ridge cap (the shingle covering at the roof’s peak) take the worst of the island’s wind and salt. Once those fasteners loosen, water gets under the shingle and into the deck.
