AfterFast, Reliable Roof Replacement & Installation Across Sanibel
Roof replacement in Sanibel typically runs $18,000 to $45,000 for a full tear-off and re-roof on a standard elevated stilt home, with metal roofing landing between $28,000 and $60,000 depending on profile and gauge. Most Sanibel jobs take 2 to 4 weeks from permit approval to final inspection, with the permit itself often the longest variable given the island’s post-Ian inspection backlog. If your roof is nearing the end of its service life or showing signs of salt-driven corrosion, call (239) 453-7751 and we’ll schedule a free on-site inspection and written line-item estimate.
We’re Winslow Windows & Doors, and while our name leads with windows and doors, our Roof Replacement & Installation crews have been rebuilding Sanibel roofs since Hurricane Ian forced the island into a full-scale reconstruction. We know what the building department on Dunlop Road requires, what the coastal HVHZ wind zone demands, and what the salt air off the Gulf and Pine Island Sound does to roofing components that would last decades on the mainland. Ed Winslow puts his name on every job we take in Sanibel, and that name means something here.
Why Winslow Windows & Doors Is Sanibel’s Preferred Roof Replacement & Installation Company
Sanibel isn’t a drive-by market for us. Our scheduling team coordinates Sanibel jobs from our South Florida office, and our crews work on the island every week. That frequency matters when you need a follow-up inspection, a flashing check after a squall, or a warranty visit on a roof we installed two years ago. We’re a local name in the way that counts: reachable, accountable, and familiar with the island’s worst-case weather.
Most of our Sanibel work now comes from referrals. Neighbors on West Gulf Drive tell neighbors on Sand Castle Road. Condo boards at complexes near Tarpon Bay Road pass our name to unit owners. That’s how a roofing company survives on a barrier island with exacting codes and an inspector who has seen every shortcut attempted after Ian. Our Sanibel customers know we pull permits, we meet the Miami-Dade HVHZ requirements, and we don’t bring Fort Myers-rated materials onto an island that requires more. Background-checked, uniformed crews arrive on time, and the phone at (239) 453-7751 is answered by a live person all day, every day.
Our 36500-Day Done Right Promise applies to every Sanibel roof we install. If it’s not done right, we make it right. No fine print, no expiration, no corporate handoff. That’s a promise with Ed Winslow’s name attached to it.
Our Roof Replacement & Installation Services in Sanibel
Full Roof Replacement
Most Sanibel homes that survived Ian need full replacement rather than patch work. We tear off to decking, inspect the substrate, and rebuild to current HVHZ code. That means Miami-Dade product approval numbers on every component, from underlayment to ridge cap. A full replacement on a 2,200 square foot elevated home near the Sanibel Lighthouse area typically runs $22,000 to $38,000 for architectural shingle systems. The work includes new drip edge, flashing, and ventilation matched to the island’s humid, salt-heavy air.
Metal Roofing Installation
Metal is becoming the default choice on Sanibel, particularly for homeowners along East Gulf Drive and the bayside streets off Sanibel-Captiva Road. Standing seam and stone-coated steel profiles handle the island’s 150-mph wind zone far better than aged shingle systems, and they shed salt spray instead of absorbing it. Expect $28,000 to $60,000 depending on panel gauge, profile complexity, and whether your decking needs replacement. Given how often Sanibel sees re-inspection for wind-load compliance, we spec metal panels with Florida Product Approval documentation from day one.
Roof Repair & Restoration
Not every Sanibel roof needs full replacement. Post-Ian, we still find homes with localized damage: lifted flashing on canal-facing eaves, corroded boots around vent stacks, punctured underlayment from flying debris off the Gulf. A targeted repair on a shingle roof near Lighthouse Point often runs $800 to $3,500. Our $40-off-any-repair-over-$200 standing offer applies to these smaller jobs, and we’ll give you a written scope before we touch anything.
Roof-to-Wall Transitions & Flashing
This is where Sanibel’s climate does its worst work. The junction between roof decking and exterior walls gets hit with salt from both the Gulf and Pine Island Sound, plus sustained wind-driven rain during summer squalls. On older stilt homes, we commonly find wicking rot at jamb-to-roof interfaces that wasn’t visible from the ground. Rebuilding these transitions with marine-grade metal and proper step flashing typically adds $1,500 to $4,500 to a project, and it’s the difference between a roof that lasts 20 years and one that fails the next inspection.

Trusted Brands We Service in Sanibel
We’re authorized installers for PGT, Mr-Glass, and Therma-Tru, three brands engineered for Florida’s wind zones. When a Sanibel roof replacement triggers code-mandated window and door upgrades, we handle the full exterior envelope so the roof-to-wall connections are built as a single system. For impact-rated laminated glass and marine-grade hardware on exposed coastal elevations, PGT’s Miami-Dade approved configurations are our standard. We stock common Mr-Glass weatherstripping and Therma-Tru hardware components for fast turnaround on repair calls around the island, from Periwinkle Way to the east-end neighborhoods.
Common Roof Replacement & Installation Problems We See in Sanibel Homes
- Fort Myers-rated materials installed on a Sanibel roof. The island sits in the HVHZ, which requires design pressures up to 40% higher than mainland Lee County. Contractors importing mainland-approved components fail inspection and you pay for a full re-do. We spec Miami-Dade NOA products from the first quote.
- Salt corrosion at roof-to-wall interfaces. Dual salt exposure from the Gulf and Pine Island Sound eats aluminum flashing, fasteners, and jamb hardware within five years on exposed elevations. Homes along the water off Dixie Beach Boulevard get it worst. Marine-grade materials aren’t optional here.
- Hidden framing rot only found when the roof comes off. Pre-Ian Sanibel homes, especially 1960s and 1970s elevated stilt cottages, often hide wicking rot at rafter tails and wall-top plates. We find it when we tear off old sheathing, and we handle it with written change orders before any new work begins.
- Original jalousie or single-pane windows left in place during a roof replacement. Once a permit is pulled and walls are opened, the building department typically requires those windows upgraded to impact-rated systems. Budgeting for this up front keeps your project on schedule.
Pricing for Roof Replacement & Installation in Sanibel, FL
A typical architectural shingle roof on a 2,000 to 2,400 square foot Sanibel home runs $18,500 to $34,000. Metal roofing lands between $28,000 and $60,000 based on profile and panel gauge. Flashing and roof-to-wall transition rebuilds add $1,500 to $4,500 when corrosion or rot is present. Decking replacement, if needed, adds $1,200 to $2,800 depending on square footage. These are real ranges from Sanibel jobs we’ve quoted and completed, not national averages. Sanibel costs run higher than Fort Myers or Cape Coral because of the island’s HVHZ wind zone, salt-air material requirements, and stricter inspection process. Call (239) 453-7751 for a written, line-item estimate. It’s free, and it’s specific to your roof.
What Roof Replacement & Installation Costs in Sanibel
For the full exterior envelope, here’s what Sanibel homeowners should know. Impact windows generally run $800 to $1,500 per window installed. Impact single-hung units land at $900 to $1,800. Large or custom openings, like a Gulf-facing picture window, run $2,500 to $5,000. Whole-home packages on a typical Sanibel stilt home fall between $8,000 and $25,000 or more depending on opening count. What moves the price on this island specifically is floor height, proximity to the water, the wind zone designation of the specific lot, and the frame material you choose. A third-story opening on the Gulf side of West Gulf Drive requires a very different design pressure than a ground-floor opening mid-island. We never quote a Sanibel job without first taking field measurements and running the specific design pressure calculations for each opening. The in-home measure and written quote are free.
Florida Pays You Back
Sanibel homeowners rebuilding after a roof replacement can stack several programs. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, including impact windows and doors installed as part of a roof replacement. Florida’s sales tax exemption applies to impact-resistant windows and doors, which saves roughly 6% to 7.5% on product costs. The federal 25C energy credit returns 30% of product cost on qualifying energy-efficient units, capped at $600 per year. After a wind mitigation inspection, which runs $75 to $150, many Sanibel homeowners see windstorm premium credits averaging about 25% on the windstorm portion of their policy. Final numbers come from your insurer and the program administrators, but these are real, stackable incentives worth reviewing before you sign any contract.

FAQs - Roof Replacement & Installation in Sanibel
Because Sanibel enforces Miami-Dade HVHZ code, and once a permit triggers a structural exterior envelope review, the existing windows and doors must meet current impact standards. Older jalousie or single-pane aluminum units don’t pass, so the building department flags them for replacement as a condition of the roof permit. We handle the roof and the window/door scope as one project, which keeps sequencing clean and avoids a second mobilization. Call (239) 453-7751 and we’ll walk the project with you before you apply for permits.
Every product we install on Sanibel carries a Miami-Dade NOA and Florida Product Approval number matched to the specific opening’s design pressure. We run the calculations for each window and door using the lot’s wind zone, exposure category, and elevation before ordering anything. The rating on the label will never exceed +/-100 PSF, and we never rely on a mainland Lee County spec for an island job. That documentation goes into your permit package before the inspector arrives.
Salt spray from two directions accelerates corrosion on aluminum frames, fasteners, and weatherstripping far faster than mainland climates. We routinely find roof-to-wall flashing and jamb hardware on Sanibel homes with pitting and white corrosion within five years of installation. That’s why we spec marine-grade hardware, stainless fasteners, and impact-rated laminated glass on any opening near the water. On a home off Dixie Beach Boulevard, these aren’t upgrades, they’re the minimum standard for the building department to pass the roof and wall assembly.
We write allowances into every Sanibel contract specifically for hidden conditions at the roof-to-wall transition. During a roof replacement on a 1970s elevated stilt cottage off East Gulf Drive, our crew uncovered failed waterproofing where the original roof met the exterior wall. The framing had wicking rot from dual salt exposure. We wrote a change order for marine-grade jamb extensions and PGT impact-rated laminated glass, then rebuilt the roof-to-wall transition with a Miami-Dade NOA assembly before the inspector returned. The homeowner knew the cost in writing before we proceeded, and the project stayed within the allowance range. That’s how inspection-first pricing works on this island. Call (239) 453-7751 and we’ll explain it in person.
Yes, most Sanibel homeowners qualify for a windstorm premium credit after a wind mitigation inspection verifies the new roof and impact-rated openings. The inspection typically runs $75 to $150, and the average credit on the windstorm portion is around 25%. The exact number comes from your carrier, but the upgrades we install meet the criteria inspectors look for: Miami-Dade NOA documentation, proper roof-to-wall attachments, and impact-rated glazing. We provide the paperwork your inspector will ask for.
