Tampa Siding Most siding contractors in the Tampa Bay area will sell you whatever you want to buy — vinyl, LP SmartSide, cedar, fiber cement from two or three different manufacturers, sometimes all out of the same truck. We don't do that. Tampa Siding Co installs James Hardie fiber cement siding exclusively. No vinyl, no engineered wood, no other fiber cement brand. This page explains why we drew that line, because "we only install one product" is a claim that deserves a real explanation, not a slogan.
The Climate Made the Decision For Us
Hillsborough County sits in a stretch of Florida that gets hit from every direction. Hurricane season brings sustained winds and wind-driven rain that pushes water sideways into wall assemblies, not just down. Summer brings months of intense UV exposure that breaks down pigments and softens some plastics and coatings. And because Tampa is a coastal-adjacent metro, salt air works its way inland further than people expect, accelerating corrosion and finish breakdown on anything not built to handle it.
Any siding material can be installed somewhere and look fine for a few years. The real test is what it looks like — and how it performs — after a decade of Gulf Coast summers and a few named storms. That's the test we're not willing to gamble a customer's siding job on.
What Wind-Driven Rain Actually Does
In a normal rainstorm, water falls down and sheds off a wall. In a hurricane-force event, wind pushes rain horizontally and even upward under eaves and around penetrations. That means every seam, joint, and fastener point on your home's exterior is a potential entry point, and the siding material itself needs to tolerate repeated wetting without swelling, delaminating, or losing its bond to its finish.
Why We Standardized on One Product
Running multiple product lines means multiple installation methods, multiple warranty structures, multiple sets of manufacturer specs to track, and multiple points where a crew can get sloppy because they're not doing the same thing every single day. When we install one product exclusively, our crews install it correctly every time because it's the only thing they do. That consistency is worth more to a homeowner than having a menu of options that we'd have to caveat anyway.
We also don't think it's honest to sell a homeowner a product we wouldn't want to be responsible for in 10 years. Vinyl siding can crack in cold snaps and warp or fade under sustained UV — it's inexpensive and easy to install, but it's not something we're willing to put our name behind as a long-term investment in a hurricane-exposed market. Engineered wood products like LP SmartSide use a wood-strand core that performs well when perfectly maintained, but they carry inherent moisture sensitivity at cut edges and joints that requires disciplined caulking and upkeep most homeowners don't realize they've signed up for. Cedar is beautiful and some homeowners genuinely want the look, but it requires the most maintenance of any option and is combustible. Other fiber cement brands exist and some are reasonable products, but Hardie has the deepest track record, the widest product lineup engineered specifically for humid climates, and the strongest factory finish system we've found.
What James Hardie Actually Is
James Hardie fiber cement siding is made from a mixture of Portland cement, sand, and cellulose fiber, cured into a dense, stable board. It doesn't have an organic wood core to rot, it doesn't contain wood strands that can swell at a cut edge, and it's non-combustible — which matters to some insurers and to homeowners who simply want one less flammable material on their exterior.
HZ5 Product Line
Hardie engineers different formulations for different climate zones. Homes in our part of Florida fall under the HZ5 climate designation, which is Hardie's product line engineered specifically for high-humidity, high-moisture-exposure regions. It's not a marketing label — the board formulation and finish system are adjusted for exactly the conditions Hillsborough County homes deal with.
ColorPlus Technology
Instead of field-painting siding after installation, Hardie offers ColorPlus: a factory-applied, baked-on finish that's more UV- and fade-resistant than a job-site paint job, and it comes with its own dedicated warranty against fading and peeling. Given how much direct sun Tampa siding takes across a full year, a factory finish that's engineered to resist chalking and fade matters more here than it would in a milder climate.

Installation Is Where Most Siding Jobs Actually Fail
Here's something worth knowing before you hire anyone for a siding job, regardless of which contractor you choose: fiber cement is installation-sensitive. The board itself is durable, but Hardie's warranty and real-world performance depend on following manufacturer specifications exactly — correct fastener type and spacing, proper clearance above rooflines and grade, correct joint flashing, and specified gaps for expansion. A beautiful Hardie installation and a problem-prone one can use the identical board; the difference is entirely in how it went up.
- Fasteners must be corrosion-resistant and driven to the manufacturer's specified depth — not overdriven, which cracks the board's edge
- Butt joints need to be properly flashed or sealed per Hardie spec, not just caulked and hoped for
- Minimum clearance from roof lines, decks, and grade must be maintained to keep the bottom edge of the siding out of standing water and splash-back
- Panels need the specified gap at trim and openings to allow for expansion and contraction
- Any field-cut edges should be sealed with the manufacturer-approved product before installation
We install to those specs on every job because that's what actually determines whether a homeowner gets 30-plus years out of their siding or starts seeing problems in year five.
The Warranty, In Plain Terms
James Hardie backs its siding with a non-prorated limited warranty (commonly 30 years on the substrate, with separate coverage on the ColorPlus finish, typically in the 15-year range depending on the product and finish selected) and the warranty is transferable to a subsequent homeowner within a set window — a real factor if you plan to sell within a decade or two of installation. We register every job properly so that warranty coverage is actually in place, not just implied.
Honest Cost Factors
We won't quote a number on a page like this because every home is different, but here's what actually drives the cost of a Hardie job up or down:
| Factor | Why It Matters |
|---|---|
| Home size and number of stories | More square footage and staging/lift needs for taller walls |
| Existing siding removal | Tear-off and disposal adds labor versus a bare-sheathing install |
| Sheathing and moisture barrier condition | Rotten sheathing or a failed house wrap has to be addressed before new siding goes on |
| Profile and trim complexity | Multiple profiles, accent walls, and custom trim details take more labor than a simple lap-siding box |
| Color and finish selection | Standard ColorPlus colors versus custom or premium finish options |
Questions Worth Asking Any Siding Contractor
- Are you a certified James Hardie installer, and can you show manufacturer training or certification?
- What fastener type and spacing will you use, and is that written into the contract?
- How will you handle the existing sheathing and moisture barrier if there's damage underneath the old siding?
- What clearance will the new siding have above the roofline, deck, and grade?
- Will you register the manufacturer warranty in my name, and can I get that confirmation in writing?
Where This Leaves You As a Homeowner
We're not going to pretend other siding products don't have a place in this market — plenty of Tampa homes have vinyl or LP siding that's holding up fine. What we're telling you is why we, specifically, stopped offering anything but James Hardie: it's the product we trust to handle Hillsborough County's wind, sun, and salt air for decades, installed to a single, consistent standard, backed by a warranty structure we can stand behind without hedging.
