Denver, CO
ROOFING ESTIMATING.
QUICK ANSWERS.
Do I need a roofing contractor license to pull permits in Denver?
Colorado does not issue a statewide roofing contractor license, but the City and County of Denver requires roofing contractors to hold a current Denver Contractor License (Roofing category) and carry minimum general liability and workers' compensation insurance before pulling a permit. You apply through Denver's eLicense portal. Working without a license or permit on a re-roof is a code violation and can void an insurance claim payout for your customer.
Does Denver require Class 4 impact-resistant shingles on re-roofs?
Denver's adopted building code does not universally mandate Class 4 IR shingles, but many insurers require or incentivize them with premium discounts, and some Denver-area HOAs specify them. More importantly, adjusters writing storm-claim estimates increasingly expect IR shingles to be called out in the contractor scope. Specifying the product and UL 2218 rating in your bid avoids back-and-forth and accelerates claim approval.
LOCAL FACTS.
Roofing installers in the Denver-Aurora MSA average approximately $28–$34/hour in 2024 (BLS Occupational Employment data), compared to a national median near $24/hour — a premium driven by altitude, sustained storm-demand cycles, and a competitive skilled-trades labor market.
Denver Community Planning and Development charges a base building permit fee plus a valuation-based component. For a typical $12,000–$18,000 residential re-roof, total permit fees commonly land in the $200–$450 range. Permits are required for re-roofs involving structural sheathing replacement; straight overlay permits may be lower but are less common post-hail.
The Denver metro averages 7–10 significant hail days per year according to NOAA Storm Events data, placing it among the highest-frequency hail markets in the country. The May–August window accounts for roughly 80% of annual hail events, creating a compressed, high-volume storm-restoration season.
