Why Denver runs above the Colorado average
Construction wages in Denver average $33.00 per hour against $31.67 statewide, so labor-heavy work prices above the Colorado norm here.
Labor is about 42% of the installed cost on this type of work, and it is the part that actually moves between markets. Materials are priced by national manufacturers and barely shift, which is why the gap between metros is narrower than wage differences alone suggest.
