How much does a roofer cost in Denver? Based on BLS OEWS May 2024 wage data and RSMeans 2024 construction costs, here are real numbers — not the "$99–$975" ranges you get from lead-gen sites.
Hail capital of the US. Insurance claims drive most replacements. Impact-resistant shingles (Class 4) earn insurance discounts. UV degradation from altitude.
Every price below is adjusted to Denver's labor market using a 1× city index applied to RSMeans 2024 national data. Labor hours assume standard conditions — add 15–40% for older homes, difficult access, or code catch-up.
