James Hardie fiber cement siding is the gold standard for Colorado homes — and Josh Brooks Construction installs it throughout Longmont, Boulder, Fort Collins, and all of Northern Colorado. Here’s everything you need to know about James Hardie siding in 2026.
Why James Hardie Is the Best Siding Choice for Colorado
James Hardie fiber cement siding is engineered specifically for regional climate extremes. Their ColorPlus Technology and HZ10 product line is formulated for the Western mountain climate — Colorado’s freeze-thaw cycles, intense UV radiation at altitude, hail events, and dramatic temperature swings.
- Hail resistant: Far more durable than vinyl under impact
- Fire resistant: Class 1 fire rating — critical for Colorado’s wildfire interface zones
- Moisture resistant: Won’t rot, warp, or swell with Colorado’s humidity swings
- UV stable: ColorPlus factory-applied paint resists fading at Colorado’s altitude
- Insect resistant: Fiber cement doesn’t attract termites or other insects
- Paintable: Unlike vinyl, you can repaint Hardie in 15-20 years for a fresh look
- 50-year limited warranty

Can James Hardie Siding Be Covered by Insurance?
Yes — if hail or storm damage caused it. Hail damage on fiber cement siding appears as circular impact marks, cracks, and chips. Josh Brooks Construction documents this damage professionally and helps you through the insurance claim process. Many Longmont homeowners upgrade from vinyl to James Hardie during an insurance-funded siding replacement.
Installation — Why Experience Matters With Hardie
James Hardie products require specific installation techniques including:
- Proper clearance from grade and rooflines
- Correct flashing at all terminations
- Stainless steel or hot-dipped galvanized fasteners only
- Caulking with approved sealants at all joints and penetrations
- Back-priming cut ends in field
Improper installation voids the James Hardie warranty. Josh Brooks Construction installs Hardie products to manufacturer specifications on every project.
