Walk into a siding conversation with most contractors and you'll hear about three or four different materials before anyone asks what your house actually needs. We don't do that. Alpine Exteriors installs James Hardie fiber cement siding exclusively — not vinyl, not LP SmartSide, not engineered wood panels. On a barrier island town like Redington Shores, where salt air, wind-driven rain, and full sun are just Tuesday, we've found that betting on one manufacturer's engineering and standing behind it fully beats juggling five product lines and half-knowing all of them.
This page isn't a general "what is siding" primer — we cover that elsewhere. This one is about the James Hardie brand itself: what makes the company's fiber cement different from generic fiber cement, what ColorPlus Technology actually does, how the warranty is structured, and why a company with Hardie's manufacturing track record matters more here than in a lot of other parts of the country.
James Hardie didn't start as a siding company chasing trends — it's the company that made fiber cement siding a mainstream category in North America starting in the 1980s, and it has spent decades since refining the formulation, the manufacturing process, and the finish system around that single product type. That kind of singular focus matters when you're deciding who to trust with the exterior of your home. A manufacturer juggling six different siding materials has divided attention; James Hardie has one job, and by most industry measures it's the most recognized fiber cement siding brand installed in the United States today.
For Redington Shores homeowners, brand reputation isn't just marketing comfort — it affects resale. Buyers and their inspectors in Pinellas County increasingly recognize the James Hardie name and understand what it signals: a fiber cement product engineered specifically for humid, coastal, high-UV climates, backed by a manufacturer that's been refining the formula for the exact conditions your house sits in.
James Hardie doesn't make one fiber cement mix and ship it everywhere. The company formulates its siding by climate zone, and Redington Shores falls squarely in the HZ5 category — the formulation built for humid, high-moisture, storm-prone regions like the Gulf Coast. That's a meaningful distinction from generic fiber cement products that use a one-size-fits-all mix regardless of whether the house sits in Arizona or on a Florida barrier island. The HZ5 formulation is engineered to resist the moisture cycling, humidity, and biological growth pressure that come standard with living two blocks from the Gulf of Mexico.
Ask any contractor who's repainted a house on the beach how long that paint job actually held up, and you'll get an honest answer: not as long as anyone wanted. Salt air, intense UV, and humidity are brutal on field-applied paint, and traditional siding — fiber cement or otherwise — usually gets primed and painted on site, which means the finish is only as good as the weather conditions and the crew's technique on install day.
ColorPlus Technology is James Hardie's answer to that problem, and it's the single biggest reason we push clients toward it rather than primed siding they'd paint themselves later. Here's what it actually is:
For a Redington Shores home facing direct Gulf sun for a good chunk of the year, that factory-cured finish is doing real work. It's not a cosmetic upgrade — it's the part of the system most exposed to the exact conditions that wear out ordinary paint fastest.
| Factor | Primed Hardie (Field-Painted) | ColorPlus Technology |
|---|---|---|
| Finish applied | On site, after installation | Factory-baked before installation |
| Upfront cost | Lower material cost, but painting adds labor | Slightly higher material cost, no separate paint job |
| Expected repaint interval | Typically sooner, especially in coastal sun | Extended — factory finish holds color longer |
| Color match after repairs | Depends on painter matching original | Manufacturer touch-up kits matched to exact formula |
| Warranty on the finish itself | Product warranty covers the board; paint is separate | Finish is warrantied as part of the ColorPlus system |
Most homeowners we work with in this area choose ColorPlus once they understand that "primed" siding isn't a finished product — it's a board waiting on a paint job that will, at some point, need to happen again.
James Hardie makes several distinct siding profiles, and which one fits your Redington Shores home depends on the architecture and the look you're after:
We'll walk your specific house and talk through which profile fits the roofline, the neighboring homes, and your own taste — this isn't a one-size-fits-all install.
James Hardie backs its siding with a non-prorated limited warranty running up to 30 years on the substrate (the fiber cement board itself), and ColorPlus finishes carry their own separate finish warranty term. A few things worth understanding plainly, because warranty language is where a lot of homeowners get misled by less reputable products:
That last point is exactly why we install strictly to Hardie's specifications — proper nailing patterns, correct starter strips, ground clearance, and flashing at every penetration. A great warranty on paper doesn't help you if the install voids it.
Redington Shores is a narrow barrier island between the Intracoastal Waterway and the Gulf of Mexico, and depending on which side of the island your home sits — Gulf-front, canal-front on the Intracoastal side, or inland along Gulf Boulevard — the exposure varies, but every property here deals with salt-laden air, high humidity, and a real hurricane season running June through November. Pinellas County building codes reflect that reality, and so does the way we spec siding.
Fiber cement in general resists moisture, salt exposure, and pest damage better than wood-based alternatives, but the HZ5 climate-specific formulation and the ColorPlus factory finish are what make James Hardie specifically well-suited to this stretch of coastline rather than just "good enough." Homes closer to Gulf Boulevard and the beach approaches take the brunt of salt spray; homes set back toward the Intracoastal side deal more with humidity and afternoon storm cells. Either way, we're not installing a generic siding product and hoping it holds up — we're installing the formulation James Hardie built for exactly this kind of exposure.
Wind resistance during storm season is another local factor. Proper Hardie installation, following the manufacturer's fastening and clearance specifications, is part of what gives the system its wind performance — another reason installation quality and warranty compliance aren't just fine print here.
Before we quote anything, we walk the exterior, note the current siding condition (especially around window and door penetrations, which is where most coastal siding failures start), and talk through which Hardie profile and ColorPlus color fit your home. Our checklist for every Redington Shores estimate:
If you're ready to talk about James Hardie siding for your Redington Shores home, we're happy to walk the property and put together a free, no-pressure estimate — no hard sell, just a straight look at what your house needs.
We'd rather be genuine experts in one manufacturer's system than spread our crew's training across several. James Hardie's HZ5 climate-specific formulation and ColorPlus factory finish are engineered for exactly the humid, salt-air conditions Redington Shores sees, and installing to one spec consistently means fewer mistakes and full warranty compliance on every job.
Primed siding is unfinished — it still needs to be painted after installation, and that field-applied paint job is exposed to the same coastal sun and humidity that wears finishes down faster. ColorPlus is a factory-baked, multi-layer color finish applied before the boards ever leave the plant, giving more consistent, longer-lasting color with manufacturer-matched touch-up kits available if it's ever scuffed.
James Hardie's limited warranties are generally transferable to a subsequent homeowner within the warranty period, which can be a real selling point on the coast where buyers ask pointed questions about exterior durability. We can walk you through the specific transfer terms and documentation when we do your install.
Confirm they're licensed in Florida (ours is RB29003900), ask specifically about their experience with Hardie's fastening and flashing specifications, and get a written scope that references those specs directly — since improper installation can affect the manufacturer's warranty coverage regardless of how good the product is.
The exposure does vary — Gulf-facing walls take more direct salt spray, while Intracoastal-facing sides deal more with humidity and afternoon storm moisture — but James Hardie's HZ5 formulation and correct flashing details handle both. We look at your specific lot orientation during the estimate rather than treating every elevation the same.
