★★★★★ 5.0 Google Rating
Trusted Roofing & Siding Contractor in Denver
Denver homeowners face a unique set of challenges that most contractors outside the Front Range simply do not understand. Sitting at exactly one mile above sea level1, the Mile High City subjects every roof and siding panel to ultraviolet radiation that is roughly 25 percent more intense than at sea level.3That relentless sunshine — over 300 days of it each year — breaks down standard asphalt shingles and vinyl siding far faster than manufacturers expect. Add the legendary Denver hail corridor2, where softball-sized stones have made national headlines, and you have a city where exterior material selection is not a cosmetic decision — it is a financial one.
We have spent years roofing and re-siding homes across Denver, from the tree-lined streets of Wash Park and the Victorian blocks of Capitol Hill to the booming new construction in Central Park and Green Valley Ranch. Whether your Craftsman bungalow in Congress Park needs a historically appropriate siding restoration or your modern RiNo townhome requires a standing-seam metal roof, we bring a material strategy that is tailored to Denver's altitude, aridity, and storm exposure. Our crews know the quirks of Denver's micro-neighborhoods — the older framing in Platt Park that demands careful decking inspection, the HOA requirements in Highlands Ranch, the wind tunnels that form near Sloan's Lake.
As a GAF Certified Plus contractor and James Hardie Preferred installer, we match Denver homes with materials engineered to outlast the altitude. Every Denver project begins with a free, no-pressure inspection and a written estimate — because this city has enough pushy salespeople, and we are not one of them.

Denver sits in what meteorologists call “Hail Alley” — one of the most hail-prone corridors in the United States.2The city averages 53 days of thunderstorms per year3, and 2 to 3 of those storms each summer produce hail large enough to damage roofing and siding.2 The Front Range's geography creates a collision zone where warm, moist air from the plains meets cold air cascading off the Rocky Mountains, fueling some of the most violent afternoon storms in the country.
Beyond hail, Denver's daily temperature swings of 30 to 40 degrees Fahrenheit3 create constant expansion and contraction stress on every exterior surface. A roof can bake at 160 degrees on a July afternoon and plunge below freezing that same night. This thermal cycling loosens fasteners, cracks brittle materials, and accelerates granule loss on shingles that were not designed for Colorado conditions.
UV radiation at 5,280 feet1 is approximately 25 percent stronger than at sea level.3 Standard vinyl siding and basic three-tab shingles degrade noticeably faster in Denver than they would in a lower-elevation city. We recommend Class 4 impact-resistant shingles and James Hardie fiber cement siding — materials specifically tested to perform in high-UV, high-hail environments like Denver.
ROOFING PERMITS & BUILDING CODES IN DENVER, CO
Denver adopted the 2021 International Building Code, and the city requires building permits for all roof replacements — no exceptions. The permitting process goes through Denver Community Planning and Development4, located at 201 W Colfax Ave, Denver, CO 80202. Inspections are required both before new materials are installed (to verify decking condition) and after the project is complete.
Denver has specific requirements for fire-rated roofing materials in certain wildland-urban interface zones, particularly in the western and southwestern parts of the city. Additionally, re-roofing over existing layers is restricted — Denver allows a maximum of two roofing layers, and many insurance companies now require a full tear-off regardless of code allowances.
We manage the entire permitting and inspection process for every Denver roofing project. Our team pulls permits, schedules inspections, and ensures every installation meets or exceeds Denver's building code requirements. You never have to set foot in a city office.
We handle all permits and inspections for you.
