Roof Replacement in Key Biscayne - Free Roof Inspection, Written Price

Fast, Reliable Roof Replacement Across Key Biscayne

A full roof replacement in Key Biscayne typically runs $18,000 – $34,000 for a mid-size single-family home, depending on the roofing system, decking condition, and whether we’re dealing with a shingle roof or a flat concrete deck. Most jobs take 7 – 14 days once materials arrive, and the permit and wind-load inspection are part of the quote, not an afterthought. We’ve been working on Key Biscayne homes long enough to know the salt air eats standard flashing within a few seasons, so we spec marine-grade fasteners and HVHZ-rated systems from day one. If you need a straight answer on price, call (850) 613-1762 and we’ll put one in writing before any work starts.

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

We answer the phone. That sounds small until you’ve spent a week leaving voicemails after a storm. Tilehurst Roofing Miami operates under the Kingswell Guarantee, which means a live person picks up 24 hours a day, seven days a week, including weekends. No callback queue, no “we’ll get back to you.” When a Key Biscayne homeowner calls about a roof replacement, they get a written price before any work starts, and a written guarantee delivered before the crew leaves the property. If something fails inside the guarantee period, we return at no charge under our 365-Day Done Right Promise.

Our crews know Key Biscayne’s housing stock: 1970s – 1990s flat concrete decks on the ocean side, newer architectural shingle roofs on the inland streets, mid-rise condominium buildings with their own roof assemblies and HOA requirements. Greg Holloway, our owner, has built this team around the Kingswell Way: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails. That’s not a slogan. It’s the standard we hold every Key Biscayne job to.

Roof Replacement Contractor in Key Biscayne

A roof replacement contractor in Key Biscayne has to operate differently than one in mainland Miami. The building code here isn’t the Florida Building Code with a wind map pulled up. It’s Miami-Dade County’s High Velocity Hurricane Zone, or HVHZ, a stricter standard that governs everything from the underlayment to the number of nails per shingle. When a Key Biscayne homeowner calls us for a full replacement, we’re not just swapping shingles. We’re assembling a system that has to pass a county uplift test, a final wind-load inspection, and a permit review that insurers examine line by line when they price windstorm coverage.

What a Compliant Key Biscayne Quote Includes

A legitimate quote for this island includes HVHZ-approved underlayment, a sealed drip edge at every eave, corrosion-resistant flashing at every penetration, and a nailing schedule that matches the manufacturer’s product approval. Cheap quotes leave those out and hope nobody looks. Our written estimates list each component separately so you can see exactly what you’re paying for and why.

Permit and Inspection Steps

Every Key Biscayne roof replacement goes through the Village of Key Biscayne building permit process, which enforces Miami-Dade product approvals. After the tear-off and before the new decking goes down, the inspector checks the fastening pattern and underlayment. After the job is complete, a final inspection verifies the HVHZ compliance. We handle the permit application, the scheduling, and the paperwork. You don’t have to chase the Village, and you get a close-out packet that your windstorm insurer can review directly.

Asphalt Shingle Roof Replacement in Key Biscayne

An asphalt shingle roof replacement in Key Biscayne means more than picking a color. Any shingle we install here has to be approved for use in the HVHZ, which narrows the field significantly. Architectural shingles from IKO, Atlas, Tamko, and Boral all have product approvals on file with Miami-Dade, but the approval only matters if the nailing pattern, underlayment, and drip edge are installed exactly as the approval specifies. That’s why we don’t let the shingle price be the whole conversation. A $14,000 tear-off and reroof can fail the wind-load inspection if the fastening schedule was guessed at.

Architectural Shingle Upgrades

Key Biscayne homeowners who want a higher wind rating often move from standard three-tab asphalt to architectural shingles, which carry thicker construction and higher uplift resistance. Atlas StormMaster and IKO Nordic are two options we install regularly on Key Biscayne. Both are rated for HVHZ use when matched with the correct underlayment and fastening pattern.

Decking Replacement Before the Shingles

When we tear off an old Key Biscayne roof, we routinely find rotted plywood at the eaves and around penetrations. Salt spray and high humidity accelerate wood decay, especially on homes built with OSB decking in the 1980s and 1990s. We replace that decking before the new shingles go down, and we show you the rotted sections before they’re covered. The decking is the roof’s foundation. Hiding a problem there is how you end up with a shingle failure inside two years.

Trusted Brands We Service in Key Biscayne

We install and service roofing systems from seven manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Key Biscayne specifically, we keep Atlas and IKO architectural shingles in regular rotation because their HVHZ product approvals are clean and their wind ratings hold up to county scrutiny. Boral makes a concrete tile product that some Key Biscayne homeowners prefer for the ocean-side aesthetic, though tile adds weight and cost. You get a real choice based on your home’s roof assembly, not whatever happens to be in the truck. Call (850) 613-1762 and we’ll walk through what each brand actually costs on your roofline.

Common Roof Replacement Problems We See in Key Biscayne Homes

• Salt-corroded flashing and fasteners. Standard galvanized flashing rusts through within a few seasons on Key Biscayne. We replace it with marine-grade alloys or stainless steel at every penetration, including vents, pipes, and the drip edge.
• Standing water on flat concrete decks. Many 1970s – 1990s flat roofs on Key Biscayne weren’t sloped properly and hold water after summer storms. That standing water saturates the deck and cracks the membrane. The fix is a new tapered system or a UV-stable coating that sheds water instead of pooling it.
• Non-compliant underlayment from old cheap jobs. If a previous roofer skipped the HVHZ-mandated underlayment, the shingle rating means nothing. Even a 130 mph-rated shingle fails the county’s uplift test when the underlayment and nailing pattern aren’t right.
• Wind-lifted drip edges at the eaves. Key Biscayne’s storm winds catch any drip edge that wasn’t sealed and fastened properly. We see lifted edges all along the ocean side, and that’s where the first leaks start.
