Why Choose HRTI in Castle Rock, Colorado?

Castle Rock has grown from about 3,900 residents in 1980 to more than 73,000 in 2020, and the town sits at about 6,200 feet, higher than most of the Denver metro area. That means plenty of homes are now 15 to 30 years old, with roofs and windows reaching replacement age, and the elevation brings stronger UV, wind, and big temperature swings. HRTI tailors recommendations to each property instead of selling one package to everyone.

Across the Denver metro, HRTI provides roofing, siding, and window & door replacement, plus storm damage repair. Browse our completed projects to see local work.

When you partner with HRTI, you benefit from:

  • Over 40 years of combined experience: HRTI crews have been working in the Denver metro area since 1972.
  • Locally owned and operated: we know the Town of Castle Rock’s building process, Front Range weather, and how HOA review works.
  • Hail Alley experience: from proactive hail-resistant upgrades to post-storm insurance claim support.
  • Manufacturer-backed warranties: available on windows, siding, and roofing.

Your Exterior Expert in Castle Rock, Colorado

Whatever the project, HRTI inspects the substrate (sheathing, flashing, moisture barriers, and framing) before installing finish materials. A new roof, window, or siding job is only as good as what it’s attached to, and hidden moisture damage is one of the most common things we find once the old material comes off.

Windows & Doors

Replacement Windows & Doors in Castle Rock

Castle Rock’s elevation means strong sun and big temperature swings, which are hard on window seals and frames. HRTI installs energy-efficient replacement windows plus entry and patio doors from brands including Pella, Sierra Pacific, Simonton, Sunrise, and Weathershield. Good windows cut drafts, help your energy bills, and protect interiors from the sun.

See our full Windows & Doors service page for the full lineup of brands and styles HRTI installs.

Siding

Siding Installation & Replacement in Castle Rock

Hail, UV, and freeze-thaw cycles all shape which siding holds up in Castle Rock. HRTI installs James Hardie fiber cement, LP SmartSide DiamondKote with RigidStack, vinyl, metal, and specialty wood siding, always over the correct sheathing. In the highest-risk wildfire zones on the town’s map, wall coverings must be noncombustible, fire-retardant-treated wood, or ignition-resistant, so material choice matters; James Hardie describes its fiber cement as noncombustible and/or Class A rated when tested under ASTM E84.

Castle Rock Exterior Remodeling FAQs

Does HRTI serve all of Castle Rock, Colorado?

Yes. HRTI serves homeowners throughout Castle Rock and the surrounding south Denver metro area. If you’re not sure your address is covered, call 303-984-6159 and we’ll confirm.

Why does Castle Rock see so much hail damage?

Castle Rock is part of Colorado’s Front Range, often called Hail Alley, which gets frequent and sometimes severe hailstorms. Roofs, siding, gutters, and window frames are the most common casualties.

Does Castle Rock have wildfire rules for roofs and siding?

The Town of Castle Rock has adopted the 2025 Colorado Wildfire Resiliency Code map. According to the Town’s Building Division guidance, re-roofs in the map’s yellow and orange-red zones need Class A roofing, and wall coverings in orange-red zones are limited to noncombustible, fire-retardant-treated wood, or ignition-resistant materials, when a project touches 25 percent or more of the roof or wall area. Parcels with no color on the map have no wildfire requirements. Confirm your address with the Town.

Do I need a permit to replace my roof, siding, or windows in Castle Rock?

Generally yes for roofing and many exterior projects, and the wildfire rules above are applied through the permit process. Confirm requirements for your specific project with the Town of Castle Rock’s Building Division, and HRTI can walk you through what applies.

My Castle Rock home is 15 to 30 years old. When should I replace the roof or windows?

It depends on materials and exposure, but Castle Rock’s rapid growth means many homes now have roofs and windows in the age range where wear, leaks, and drafts show up, and hail can speed that up. A free inspection from HRTI can tell you what needs attention now and what can wait.

What siding holds up best against hail in Castle Rock?

James Hardie fiber cement and LP SmartSide DiamondKote with RigidStack are generally the strongest options HRTI installs for hail-prone areas. The best choice for your home also depends on its style, your budget, any HOA rules, and your wildfire zone.

Does HRTI help with insurance claims after a hailstorm?

Yes. HRTI offers free storm-damage inspections, documents the damage so you have a clear record, and can meet your insurance adjuster on site.
