Longboat Key is a narrow barrier island wedged between the Gulf of Mexico and Sarasota Bay, and that geography changes how storm damage shows up on a house here compared to almost anywhere else Alpine Exteriors works in the region. A wind event that leaves a Lakewood Ranch roof with a handful of lifted shingles can strip flashing, crack stucco, and drive water behind siding on a Longboat Key home in the same afternoon, because there's nothing between these houses and open water to slow the wind or the salt riding on it. We repair roofs, siding, soffit, fascia and windows on the Key after named storms, straight-line wind events, and the slower damage that spray and UV do to a home over a normal Gulf-front season.
What we're usually called out for after weather here isn't always dramatic. It's as often a run of lifted shingle tabs along a ridge, a section of soffit that's been sucked loose and is now letting birds and moisture into the attic, or hairline cracks around window frames that turn into active leaks the next time it rains sideways. On the Key, small openings matter more than they would inland — wind-driven rain off the Gulf finds gaps that would stay dry fifteen miles east.
Most of our Longboat Key calls fall into three categories: roof repair after wind or hail, siding and stucco repair where wind uplift or debris impact has separated material from the wall, and window or door repair where seals or frames have failed under repeated storm pressure. Because a large share of Longboat Key housing stock is mid-rise condominiums and villas as well as single-family homes, we also do a fair amount of coordination work — meeting with a condo association's property manager or engineer before we touch a unit, since roof and exterior wall work on attached buildings usually has to be scoped and approved at the association level, not just the homeowner's.
We inspect before we quote. On a barrier island, damage that looks cosmetic from the ground — a stained soffit panel, a slightly bowed siding course — is frequently a sign that water has already been getting behind the exterior for a while, sometimes from a storm two or three seasons back that never got fully addressed. We'll tell you plainly if what you're looking at is a patch job or if it points to something that needs to come off the wall or roof deck to be repaired correctly. Alpine Exteriors would rather lose a smaller job than sign off on a repair that fails again next hurricane season.
Three things drive almost every decision we make on a Longboat Key exterior: salt, wind, and sun. The salt air corrodes exposed fasteners, hinges, and untreated metal far faster than it does even a few miles inland — steel screws and standard flashing can show rust streaks within a couple of years on a Gulf-front elevation. We use stainless or coated corrosion-resistant fasteners and flashing on Longboat Key jobs as a default, not an upgrade, because the alternative is a repair that needs redoing.
Wind is the second factor. Longboat Key sits in Florida's wind-borne debris region under the Florida Building Code, which means new and replacement windows and doors on most of the island need to be impact-rated or protected by code-approved shutters, and roofing has to meet elevated wind-uplift standards. This isn't unique to storm-damage repair — it applies to routine replacement too — but after a storm it matters more, because you're often repairing a system that was installed under an older, less strict code cycle. Bringing a damaged section up to current wind standards, even when only part of the roof or wall needs work, is usually the right call structurally, even where it isn't strictly required for a repair-only permit.
Sun is the quieter factor. UV exposure on this stretch of coast is intense and constant, and it degrades sealants, vinyl, and unprotected trim faster than inland exposure does. A repair that looks fine in month one can fail in month eighteen if the sealant or coating used wasn't rated for reflective, high-UV coastal exposure.
For roofing, we lean toward architectural asphalt shingles with a high wind-uplift rating for most single-family repairs, and standing seam aluminum (not steel) for homeowners who want a metal roof — aluminum resists salt corrosion far better than coated steel over the long run, even though it costs more up front. Tile remains common on the Key and can be repaired in kind, but matching older discontinued tile profiles is sometimes the hardest part of a tile repair, not the labor.
For siding and cladding, fiber cement (HardiePlank and similar) holds up well against salt and UV and is our default recommendation for exterior wall repairs here. Vinyl siding is less expensive but tends to become brittle and discolored faster in this exposure, and we're upfront with clients about that trade-off rather than steering everyone toward the priciest option. Stucco is extremely common on the Key's condo and villa stock, and stucco repair has to be matched carefully in texture and coating or the patch will telegraph visually for years.
For windows, impact-rated aluminum or vinyl-clad frames are the practical standard given the wind-borne debris code, and they remove the need to install and store shutters before every storm — a real convenience for owners who aren't on the island full-time, which is common here.
Longboat Key is its own incorporated town with its own Building Department, separate from both Sarasota County (which covers the island's southern portion) and Manatee County (which covers the northern portion) — permitting here runs through the Town, not the county, for most exterior work. Roof replacement, siding replacement, and window/door replacement virtually always require a permit; like-for-like repair of a small damaged area sometimes doesn't, but the threshold is narrow enough that we pull permits by default rather than guess wrong.
Two things make Longboat Key permitting slower than a typical mainland job. First, condominium and multi-family buildings often need association or engineer sign-off before the Town will process a permit, which adds a step outside our control — we build that lead time into the schedule rather than promise a date we can't back up. Second, much of Longboat Key sits in FEMA flood zones AE or VE, and if storm damage is severe enough to trigger the 50% substantial-improvement rule (repair cost exceeding half the structure's assessed value), the project can get pulled into flood-elevation requirements that go well beyond the original damage. We flag that possibility early if a job is large enough to be anywhere near that threshold, because it changes both scope and cost.
Costs on Longboat Key repairs run higher than comparable work a few miles inland, mainly because of material choice (corrosion-resistant fasteners and flashing, higher-grade coatings), access logistics on a narrow island with limited staging space, and, for condos, the added coordination time. As rough ranges: localized roof storm repair often falls between $1,500 and $8,000 depending on the extent of decking or flashing damage; siding or stucco repair sections typically run $2,000 to $10,000+ depending on how much wall assembly has to be opened up; impact-rated window replacement generally runs $900 to $2,200 per opening installed. Full roof or siding replacement after major storm damage is a different conversation and depends heavily on square footage, roof pitch, and material — we won't quote that without walking the property. None of these numbers are guarantees; they're the range we typically see, and every barrier-island job has the potential for hidden damage once material comes off.
In most cases, yes. The Town of Longboat Key Building Department requires permits for siding and roofing replacement and for most repairs beyond very small, like-for-like patches. We pull permits as standard practice so the work is inspected and documented, which also matters for insurance claims and resale.
Yes. We regularly work with property managers, boards, and their engineers on attached-building exteriors. We can inspect and provide documentation the association needs, then perform the approved work once it's authorized through their process.
Longboat Key falls in Florida's wind-borne debris region, and code often requires repaired or replaced sections to meet current wind-uplift standards rather than the standard the roof was originally built to. It adds some cost, but it's the standard designed for this specific coastline.
It depends on the extent of regional damage and permit turnaround at the Town, which can slow down after widespread storm events when many properties are filing at once. We prioritize active leaks and structural exposure first and give an honest timeline once we've inspected, rather than a number that sounds good over the phone.
If your Longboat Key home or condo took wind or water damage, the sooner it's inspected the less likely a small problem turns into a rot or mold issue behind the wall or roof deck. Alpine Exteriors serves Longboat Key along with Sarasota, Siesta Key, Venice, Osprey, and Lakewood Ranch, and we're familiar with the Town's permitting process and the material standards this coastline requires.
