Key numbers
45 verified hail storms with stones of 1.75 inches or larger reached Denver County from 1984 to 2026 in the storm records we keep; the largest measured 4.5 inches (softball size) on July 13, 2011 (NOAA NCEI).

A storm counts when the library lists Denver County among the areas it hit. Each hail size is the storm's largest report, which may have fallen in a neighboring county, and insured losses cover every area the storm hit.
Residential roofing in Denver means choosing a roof that can handle hail, high wind, heavy snow, and strong high-altitude sun, then installing it to Denver’s code: no more than two layers, shingles rated for your wind zone, and a city permit. Integrity Roofing and Painting installs asphalt, metal, synthetic cedar, tile, and slate roofs across the metro, and most replacements are finished in a day or two.
Roof types we install in Denver
- Asphalt shingles. The most common Denver roof: affordable, available in many colors, and available in impact-resistant versions that hold up better to hail. Our Class 4 shingle comparison explains the ratings.
- Metal roofing. Durable and energy efficient. It sheds snow and its reflective finishes help keep the house cooler in summer.
- Synthetic cedar. The look of wood shakes without the rot, insect, and maintenance problems of real wood.
- Tile. Clay or concrete tile lasts for decades with proper care and resists fire. Tile is heavy, so the framing has to be able to carry it.
- Slate. The longest-lasting roof you can buy, with natural texture and color variation. It is also the most expensive.
What Denver code requires on a new roof
- A permit. Every replacement needs a Denver permit, and we pull it.
- Two layers at most. If your home already has two layers, everything comes off to the deck. We tear off to the deck on every replacement so we can inspect and repair the decking.
- Wind-rated shingles. Shingles must be labeled to ASTM D7158 (or D3161) and rated at least 115 mph east of Federal Blvd, 125 mph from Federal to Sheridan Blvd, and 140 mph from Sheridan Blvd to Kipling St.
- Insulation in some cases. If the roof has no insulation in the cavity and the sheathing is exposed during reroofing, Denver’s energy code requires adding it (R-30ci above the sheathing, or R-38 flat or R-49 attic below).
- Asbestos rules on older roofs. Colorado’s CDPHE rules can require a certified asbestos inspection before tear-off.
Our Denver roofing codes article covers more of the local code.
Our Denver roof installation process
Every roof follows the Integrity Roofing System, our written install checklist. In short: a pre-construction checklist and permit, landscaping and decking protection, tear-off to the deck, ice and water shield, underlayment, a windstorm starter strip, new valley, wall, and pipe flashing, shingles, hip and ridge, ventilation, cleanup, and inspections. Denver’s guide does not require an ice barrier at the eaves; we install ice and water shield anyway.
What a new Denver roof costs
Price depends on size, pitch, material, and whether the decking needs work. Read how much a roof replacement costs in Denver. If hail caused the damage, your homeowners policy may cover much of it; the claim stays yours, and our photos make sure nothing gets missed in the scope. Financing is available too.
