Fast, Reliable Shingle, Tile & Metal Roofing Across Key Biscayne
Shingle, tile, and metal roof repair in Key Biscayne typically runs $450–$1,800 for targeted fixes, while full replacements on the island start around $18,000 and climb past $60,000 for tile and standing-seam metal on larger homes. Most jobs take one to three days for repairs and one to two weeks for complete tear-offs. If you’re noticing rust streaks, cracked barrel tile, or granules washing into your gutters after a storm, call (844) 901-4551. We’ll send a background-checked, uniformed technician to your Key Biscayne home, assess what’s actually failing, and give you a written line-item quote before any work begins.
We know what Key Biscayne’s salt air does to roofing systems. The same true barrier-island geography that makes this community beautiful also means every roof takes simultaneous salt spray from Biscayne Bay on the west and the Atlantic on the east. There’s no mainland buffer here. That changes what fails first, what materials last, and what a repair should actually cost.
Why Winslow Windows & Doors Is Key Biscayne’s Preferred Shingle, Tile & Metal Roofing Company
Ed Winslow founded this company in 2011, and his name is on the door, on every job, and on the Done Right Promise that backs every installation. If it’s not done right, we make it right. No fine print. No national-chain ticket number. Just a local owner who lives with the same hurricane seasons, the same salt air, and the same Miami-Dade codes you do.
Key Biscayne homeowners call us because we answer the phone. A live person picks up 24 hours a day, seven days a week. Not a voicemail loop. Not a call center. When your tile roof loses a cap after a squall or your metal roof starts lifting at the ridge line, you reach a person who knows Key Biscayne and can talk through what you’re seeing. Our crews serve Key Biscayne locally, coordinated from our Miami (South FL) office.
We’ve worked on 1960s condo towers off Crandon Boulevard and post-Andrew single-family homes near Mashta Island. We’ve seen the corrosion patterns, the rusted fasteners, the cracked underlayment. That local experience matters when you’re deciding whether to patch or replace. For roofers who don’t work this island, Key Biscayne is a place they visit. For us, it’s a community we serve year-round.
Our Shingle, Tile & Metal Roofing team handles everything from small repairs to complete replacements, and we install products from authorized brands including CGI, CWS, and ES Windows for integrated window and door protection that works with your roof system.
Our Shingle, Tile & Metal Roofing Services in Key Biscayne
Shingle Roof Repair & Replacement
Asphalt shingle roofs across Key Biscayne’s 33149 zip code face accelerated granule loss from constant salt exposure and UV. Most shingle repairs run $450–$950 when we catch them early: a lifted shingle tab, a small wind-damaged section, a nail pop at the ridge. Full shingle replacements on Key Biscayne homes typically run $18,000–$32,000 depending on square footage, pitch, and whether the existing underlayment can stay. We use high-wind nailing patterns and Miami-Dade approved underlayments on every shingle job on the island.

Tile Roof Repair & Replacement
Barrel tile and flat concrete tile dominate Key Biscayne’s luxury home inventory, and they fail differently here than anywhere else. Salt spray accelerates fastener corrosion, so a tile that simply looks out of place or slides down the roof plane usually means rusted nails or screws underneath. Broken or cracked barrel tile repairs run $350–$750 per section. Full tile roof replacement on a typical Key Biscayne home runs $30,000–$60,000 or more, and the biggest cost driver is the tile profile itself. Certain Spanish S-tile profiles have to be custom ordered, which adds fabrication time. We’ll match existing tile by profile and color, and we photograph every step so you see exactly what’s happening on your roof.

Metal Roof Installation
Standing-seam metal roofs are gaining ground in Key Biscayne for good reason. They shed wind-driven rain better than shingle, resist the island’s salt spray when properly spec’d with marine-grade fasteners, and carry some of the strongest wind ratings available. Metal roof installation on Key Biscayne homes starts around $22,000 on smaller residences and runs $40,000–$75,000+ on large single-family homes depending on seam profile, panel gauge, and whether we’re doing a full tear-off. The key in this environment is the fastener and clip package. We only use stainless steel fasteners on Key Biscayne metal roofs. Galvanized fasteners rust through within a few years here, and we won’t install a roof we know will fail early.

Roof Inspections & Storm Damage Assessment
After any significant storm, Key Biscayne homeowners should have their rooflines checked. Wind-driven rain from both the bay and ocean exposures finds every gap, every cracked tile, every lifted shingle. We perform detailed roof inspections and document findings with photos, so you can file an insurance claim with evidence in hand. Storm damage assessment on the island costs $250–$450, and we’ll provide a written report with clear repair recommendations.

Common Shingle, Tile & Metal Roofing Problems We See in Key Biscayne Homes
- Rusted fasteners on tile roofs. The 360-degree salt exposure around Key Biscayne corrodes standard roof nails and screws faster than virtually any other South Florida community. A tile that looks fine from the ground can be hanging on a fastener that’s already lost half its diameter. We replace fasteners with stainless steel on every tile repair.
- Granule loss on shingle roofs facing both water exposures. Shingle roofs on Key Biscayne take salt spray from Bathtub Beach and the bay side simultaneously. That accelerates granule loss and exposes the asphalt to UV breakdown. If your gutters are filling with black granules, the shingles are aging faster than their calendar age suggests.
- Lifted ridge caps on metal roofs. The island’s wind patterns create channelled gusts between condo towers and across the causeway approaches. Ridge caps and standing-seam clips take repeated uplift cycles. A loose ridge cap on a Key Biscayne metal roof is not a cosmetic issue; it’s the first stage of a wind-driven rain intrusion.
- Deteriorated underlayment under tile roofs. The original underlayment on many 1980s and 1990s Key Biscayne tile roofs was not designed for this salt load. We regularly pull up cracked tile to find underlayment that has turned brittle and lost its waterproofing. When that happens, the fix is not another tile replacement. It’s a section re-deck and new high-wind underlayment.
What Shingle, Tile & Metal Roofing Costs in Key Biscayne
Here’s what we actually quote on the island. Targeted shingle repair: $450–$950. Tile repair (including fastener replacement): $350–$750 per section. Metal roof repair: $500–$1,200 depending on seam type and whether clips need replacement. Full shingle replacement on a Key Biscayne home: $18,000–$32,000. Full tile replacement: $30,000–$60,000. Standing-seam metal installation: $22,000–$75,000+. These ranges reflect the island’s material requirements: stainless fasteners, Miami-Dade NOA underlayments, and often custom tile profiles that add fabrication time.
What moves the price? Roof square footage first. Then roof pitch and accessibility (some Key Biscayne homes have tile profiles that require special handling). Then condition of the existing decking: if salt intrusion has rotted the plywood or the concrete tile anchors, that adds scope. We write allowances into every quote so you know what a decking replacement would cost if we find rot. You get a written line-item quote before work starts, and any surprise is priced and approved in writing before we touch it.

Florida Pays You Back
Wind-mitigation improvements on Key Biscayne homes often qualify for real financial incentives, and they stack. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, including roof-to-wall connections, secondary water barriers, and impact-rated opening protection. Florida also exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit can return 30% of product cost, up to $600 per year on qualifying units. And after a wind-mitigation inspection ($75–$150), many Key Biscayne homeowners see windstorm premium credits averaging around 25% on the windstorm portion of their policy. Programs and carriers set the final numbers; we’ll show you what documentation you need.
One more thing worth knowing when you’re comparing options: impact-rated windows and doors beat hurricane shutters in one critical way for Key Biscayne living. Shutters only help if you’re home to hang them before a storm, and they do nothing for the daily salt-air corrosion that eats at your openings year-round. Permanent impact protection works 365 days a year, not just during hurricane watches. If you’re replacing a roof anyway, it’s the right time to check whether your windows and doors meet Miami-Dade HVHZ standards.
Pricing for Shingle, Tile & Metal Roofing in Key Biscayne, FL
A typical asphalt shingle repair in Key Biscayne runs $450–$950, and full shingle roof replacement on an average island home starts around $18,000. Tile roof work runs higher: broken tile sections cost $350–$750 to repair, and a full tile roof replacement on a larger Key Biscayne property can reach $60,000. Metal roofing falls in the middle to upper range, with repairs at $500–$1,200 and full standing-seam installations from $22,000 to $75,000 depending on panel profile and roof complexity. These are real numbers from jobs we’ve quoted and completed in Key Biscayne, not national averages.
The island’s requirements push costs higher than mainland Miami. Stainless steel fasteners are mandatory here; galvanized hardware fails early. Miami-Dade NOA underlayments cost more than standard felt but they’re non-negotiable. And some tile profiles on Key Biscayne’s older homes are no longer manufactured, which means custom fabrication and longer lead times. We account for all of this in the quote, not after work starts. Free estimate: call (844) 901-4551.
Ed Winslow’s approach to pricing is simple. Inspection first. Allowances written into the contract for hidden decking or structural repairs. Any surprise priced in writing and approved by you before we touch it. No change orders that blindside you at invoice time.

FAQs — Shingle, Tile & Metal Roofing in Key Biscayne
The original 1960s and 1970s aluminum sliding glass doors in Key Biscayne’s condo towers were installed with anchors and frame details that don’t meet today’s Miami-Dade HVHZ requirements, and decades of salt-air corrosion from the island’s 360-degree exposure have often deteriorated the concrete surrounding the frame. When we pull the old door, we find crumbling spalls, rusted anchors, and enlarged openings that need remediation before the new impact-rated frame can be installed and pass its NOA inspection. On a 1970s condo replacement in the 33149 towers off Crandon Boulevard, our crew found original storefront-style frames so corroded that the sash seized when we tried to open them. We switched every sliding door to marine-grade stainless-steel rollers and hinges, upgraded to impact-rated glazing with a laminated glass interlayer, and torqued the replacement frames to design-pressure requirements before the Miami-Dade NOA inspection. Call (844) 901-4551 and we’ll tell you honestly what your condo’s opening will need.
HVHZ compliance adds about 15–30% to a typical Key Biscayne shingle or tile roof replacement compared to non-HVHZ mainland work. The additional cost comes from stronger underlayment, more fasteners per square, stainless steel hardware throughout, and the inspection and paperwork burden of Miami-Dade Notice of Acceptance documentation. Key Biscayne’s barrier-island geography means every roof takes simultaneous wind and salt load from the Atlantic and Biscayne Bay, so we can’t cut corners on fastener grade or underlayment spec. Our quotes include all HVHZ requirements upfront, so the number you see is the number the job costs. Free second opinions on written estimates are available to Key Biscayne homeowners; call (844) 901-4551 to schedule.
We look for it specifically on every Key Biscayne inspection because the island’s salt air and wind-driven rain make hidden water intrusion more common here than on the mainland. We check corners, flashing junctions, and the interior side of roof penetrations. We use a moisture meter on suspect areas and we’ll tell you if the staining under the roof edge is historic or active. If we suspect water is getting behind the stucco or drywall at a roof junction, we’ll recommend an invasive inspection before recommending a roof repair. Finding it early is the difference between a $600 flashing repair and a $35,000 structural remediation. Call (844) 901-4551 to book a Key Biscayne roof inspection.
No, you do not need to replace every window in your Key Biscayne home to receive a wind-mitigation credit under Florida Statute 627.0629. The credit applies per opening. Each window or door that receives impact-resistant glazing with a valid Miami-Dade Notice of Acceptance (NOA) or Florida Product Approval number counts toward your home’s wind-mitigation score. A wind-mitigation inspector evaluates the entire home and documents which openings are protected, and your insurance carrier applies the credit accordingly. Many Key Biscayne homeowners phase the work, starting with the ocean-facing or bay-facing elevations. We’ll provide all the NOA documentation for every opening we replace. Call (844) 901-4551 for a free estimate on phased window and door replacement in Key Biscayne.
We write an allowance into every Key Biscayne roof replacement contract that covers rotted decking, damaged fascia, or deteriorated structural framing discovered after the old roof comes off. When we find rot, we stop and show you photos, then give you a written price before we cut anything. Most decking replacements add $3–$8 per square foot depending on material and whether we’re re-sheathing a small section or the whole roof plane. You approve the scope in writing before we proceed. On older Key Biscayne homes, especially those built before Miami-Dade’s current code, we expect to find some rot at the eaves where salt-laden moisture accumulated for decades. The allowance keeps the job predictable. Call (844) 901-4551 for a quote on your Key Biscayne roof.
The Older Key Biscayne Home Reality: What Opens Up When the Walls Come Open
Here’s what opening up an older Key Biscayne home actually turns up. Outdated wiring that no longer meets code. Undersized or damaged framing around window and door openings. Failed waterproofing that’s been silently rotting the sheathing behind your stucco. And code upgrades that a permit triggers once the walls are open, like hurricane straps at roof-to-wall connections and impact-rated anchors that weren’t required when the home was built.
This is the single biggest reason a Key Biscayne remodel quote moves. Not because the contractor is padding the estimate. Because the house is telling the truth once the drywall comes down. We handle it differently than most. First, every Key Biscayne project starts with a detailed inspection so we can identify likely failure points before demolition begins. Second, we write explicit allowances into the contract for wiring, framing, and waterproofing discoveries. Third, any surprise is priced and approved in writing before we touch it. You never get a call that starts with “we found something” and ends with an unapproved invoice.
The island’s true barrier-island geography means every roof and every opening has simultaneous salt-spray exposure from the Atlantic and Biscayne Bay with no mainland buffer, and Miami-Dade HVHZ code demands the strictest NOA-certified roofing and wind-mitigation details in the United States. No neighboring mainland ZIP shares that combination. That’s why a Key Biscayne window or door replacement unfolds differently than it would in Coral Gables: the hidden corrosion, the flood-zone threshold triggers, and the NOA-driven anchor upgrades are all part of the job. We plan for them. We price for them. And we show you the evidence.
