James Hardie Siding Longmont CO | Authorized Installer

“I’ve been installing James Hardie and other siding products across Northern Colorado since 2014. In this climate — the UV exposure, the hail, the freeze-thaw cycles — the siding material you choose makes a real difference in how long it holds up and what it costs you over time. Fiber cement consistently outperforms vinyl here. That’s not a sales pitch; it’s just what I see job after job.”

Why Siding Matters More in Colorado Than Anywhere Else

Between hail, UV exposure, and freeze-thaw cycles, Colorado’s climate is harder on siding than almost any other state.

“James Hardie fiber cement is the only siding I recommend for Colorado homes. I’ve installed it since 2014 and I’ve seen it take direct hail hits that would have destroyed vinyl or wood. The insurance discount alone can offset a significant portion of the project cost.”

How long does James Hardie siding last in Colorado?

James Hardie fiber cement siding carries a 30-year ColorPlus Technology warranty on the factory finish and a 30-year limited warranty on the product itself. In Colorado’s high-UV, hail-prone climate, it consistently outperforms vinyl and wood alternatives, which typically need replacement or major maintenance within 15-20 years.

Does James Hardie siding protect against hail in Colorado?

Yes. James Hardie fiber cement siding achieves a Class 4 impact resistance rating under ANSI/FM 4473 testing — the highest rating available — meaning it can withstand hailstones up to 2 inches in diameter without cracking or breaking. Most Colorado insurance carriers offer premium discounts for Class 4 rated siding.

How much does James Hardie siding cost in Colorado?

Josh Brooks Construction and Renovation Inc. prices siding by the square (100 square feet of wall): primed James Hardie siding is $1,600 per square, James Hardie ColorPlus with its factory finish is $2,200 per square, and LP SmartSide is $1,500 per square. Painting primed Hardie or LP as part of the install adds $5 per square foot ($500 per square); painting alone, without new siding, runs $7 to $8 per square foot. The total depends on wall area, trim detail and number of stories, and you get a fixed, itemized bid before any work starts.

Is James Hardie siding covered by insurance after a hailstorm?

Yes, in most cases. If hail damage is documented and exceeds your policy’s deductible, most Colorado homeowner policies will cover siding replacement. We document every impact point, attend the adjuster meeting, and ensure Ordinance and Law coverage is applied where applicable for code-compliant installation.

What is the difference between HardiePlank and HardiePanel?

HardiePlank is a horizontal lap siding profile — the most popular James Hardie product — while HardiePanel is a vertical panel system often used for board-and-batten looks or on specific architectural sections. Both use the same fiber cement composition and carry the same warranty. The right choice depends on your home’s architectural style.

Do I need a permit for siding replacement in Longmont?

In most cases, yes. Longmont requires a building permit for full siding replacement. Josh Brooks Construction and Renovation Inc. pulls all required permits on every siding project — no exceptions. An unpermitted siding job can create problems with your homeowner’s insurance and at resale.
