If you've been comparing siding options for a home in Redington Shores, vinyl probably came up first. It's the material most siding ads talk about, and on paper it looks cheap and low-maintenance. We want to be upfront before you read another word: Alpine Exteriors doesn't install vinyl siding, LP SmartSide, or any engineered wood product on any home, anywhere in our service area — including here on the barrier island. We install James Hardie fiber cement siding exclusively, and on a strip of land this exposed to the Gulf of Mexico, that's not a marketing preference. It's the standard we've settled on after seeing how each material actually holds up between Boca Ciega Bay and the open Gulf.
Redington Shores is a narrow barrier island in Pinellas County — a few blocks wide in most places, with Gulf Boulevard running down the spine of it. Homes here sit close to salt water on two sides at once: open Gulf surf to the west, the Intracoastal Waterway and Boca Ciega Bay to the east. That double salt-air exposure, combined with direct hurricane-season wind loading, is a tougher test for exterior materials than almost anywhere else in the county. This page walks through why that matters for your siding choice, and what we actually install instead.
Vinyl siding is thin, interlocking PVC panels installed with a hanging-hem system that relies on the panel being able to move slightly with temperature changes. That works fine in a lot of the country. On a barrier island in west-central Florida, three things work against it at once.
Unshaded stretches of Gulf Boulevard and the open lots closer to the beach get intense, reflected sun off both water and sand for most of the day. Vinyl expands, contracts, and can warp or bow over years of that cycle — especially on south- and west-facing walls with no tree canopy to break up the exposure.
Redington Shores sits in one of the higher wind-design zones in Pinellas County. Vinyl panels are rated for wind resistance, but the rating depends entirely on correct, tight fastening — and even installed well, vinyl is a lighter, more flexible material that's more prone to panel lift, cracking at the locking edges, and full panel loss in sustained tropical-storm-force gusts than a heavier, mechanically fastened product.
Salt aerosol off the Gulf settles on everything on this island, siding included. Over time it accelerates UV breakdown of PVC, and vinyl that's already a few years old gets noticeably more brittle — a panel that flexes fine at year two can crack on impact at year twelve. On a barrier island, "year twelve" arrives faster than it does further inland.
James Hardie siding is a cement, sand, and cellulose fiber composite, not plastic and not wood. It's manufactured in a version engineered specifically for humid, high-moisture climates — Hardie's HZ5 formulation, which is what we spec for this part of Florida — and it addresses the exact three weak points vinyl has here.
We install it in the lap plank profile most often, which gives you the same clean horizontal-board look people associate with classic Florida coastal cottages — without the tradeoffs of the material that "coastal siding" usually means.
Not every lot in Redington Shores faces the same conditions. A home directly on Gulf Boulevard or one of the beach-access streets takes more direct salt spray and wind than a home a few blocks east on a canal or bay-facing lot. We walk every property before quoting and adjust the fastening schedule and flashing detail based on which side of the island — and which direction — a given wall faces, not a one-size approach for the whole job.
Most homes on the island are either older concrete block construction at or near grade, or newer/renovated homes elevated on pilings to meet current flood elevation requirements. Elevated homes expose more wall area — and often the understructure — to wind and moisture than a slab home does, which changes how we detail the bottom course of siding, the transition at the elevated floor line, and any exposed piling wraps.
| Factor | Vinyl Siding | James Hardie Fiber Cement (what we install) |
|---|---|---|
| Wind performance in coastal wind zones | Rated but flexible; panels can lift or crack in sustained gusts | Rigid, direct-fastened board; performs to a higher engineered wind standard |
| Salt air / UV exposure over time | Becomes brittle, fades, can chalk | Doesn't degrade from UV or salt; holds finish |
| Heat expansion on sun-exposed walls | Warps or bows on unshaded south/west walls | Dimensionally stable |
| Fire resistance | Combustible (melts/burns) | Non-combustible |
| Repaint / color change | Not really paintable long-term | Paintable and holds finish for years |
| Typical realistic lifespan on the island | Shorter, especially Gulf-front | Decades, with normal maintenance |
Any siding replacement here needs to meet Pinellas County's current wind-load and building code requirements for this zone, and on some properties that means pulling permits through the Town of Redington Shores directly. We handle that process, including any documentation needed for insurance purposes after the job — a properly permitted, code-compliant install matters if you ever file a wind or storm claim.
Before a single piece of siding goes up, we install a weather-resistant barrier and detail flashing at every window, door, and penetration. This step matters more here than almost anywhere — humid Gulf Coast air plus any gap in the moisture barrier is how you end up with hidden rot or mold behind the wall years down the road. We don't shortcut this even though it's invisible once the job is done.
Hardie board gets nailed at a tighter, code-specified spacing in high-wind zones like this one than it would in a calmer inland market. We follow the manufacturer's high-wind fastening schedule, not the minimum spec, on every job on the island.
Redington Shores lots tend to be narrow, with close neighbors and limited staging space, especially on the streets closest to the beach. We plan material staging and daily cleanup around that reality so your project doesn't turn into a blocked driveway or a mess spilling onto a neighbor's yard.
| Cost factor | Why it matters here |
|---|---|
| Home elevation (slab vs. pilings) | Elevated homes have more exposed wall area and more complex transition detailing |
| Existing siding removal | Older block homes may have multiple layers of prior siding or stucco patch repair underneath |
| Wall condition underneath | Any hidden moisture damage found during tear-off adds repair scope before new siding goes on |
| Access and staging | Narrow lots, seawalls, or limited street parking can affect labor time |
| Trim and architectural detail | Corner boards, window trim, and fascia work add to the scope beyond flat wall area |
| Color and finish | Factory-primed vs. ColorPlus prefinished Hardie affects material cost and finish durability |
We give you an itemized, honest number after walking the property — not a rough square-footage guess over the phone.
One thing worth being direct about: no siding on a barrier island is "zero maintenance," and anyone who tells you otherwise is selling you something. What Hardie gives you here is a material that doesn't degrade on its own timeline the way vinyl does. Realistic upkeep is an annual rinse to knock off salt residue, a periodic check of caulking at trim and penetrations, and a repaint on a normal multi-year cycle depending on sun exposure and color choice. That's a manageable routine compared to dealing with cracked, sun-faded vinyl panels that can't be spot-repaired without an obvious color mismatch.
Because Redington Shores sits in a demanding wind and flood zone, the contractor matters as much as the material. Before hiring anyone for siding work here, it's worth checking:
Alpine Exteriors holds Florida license RB29003900 and works this part of Pinellas County regularly, so we know what these lots and this exposure actually require before we ever quote a job.
If you started out searching for vinyl siding installation, we'd rather explain why we'd steer you toward James Hardie fiber cement for a Redington Shores home than sell you a product we don't think holds up out here. Fill out the form below for a free, no-pressure estimate — we'll walk your property, talk through what your specific exposure calls for, and give you a straight answer.
No. We only install James Hardie fiber cement siding, on every home we work on, regardless of the request. We'd rather explain why fiber cement performs better in this exposure than install a product we don't think is right for a barrier island home.
Confirm an active Florida contractor license and insurance directly through the state lookup, ask for a written scope that includes moisture barrier and flashing detail, and ask specifically about their experience with Pinellas County's wind-load requirements. A contractor who's vague on wind-load specs for this zone hasn't worked enough coastal jobs.
HardiePlank is the horizontal lap board profile, the most common choice for the classic coastal cottage look on the island. James Hardie also makes panel and shingle-style profiles for different architectural styles, and we help homeowners pick the profile that fits their home rather than defaulting to one option.
Hardie offers both factory-primed board, which we paint after install with a coastal-grade exterior finish, and ColorPlus prefinished board with a baked-on factory finish that resists fading longer. We'll go over both options and what each means for your repaint schedule.
Homes raised on pilings expose more wall area, including transition points at the elevated floor line, to wind and moisture than a slab home does. We detail flashing and the bottom course of siding differently on elevated homes to account for that extra exposure, and we factor it into the estimate up front.
