Roofing Estimating Softwarefor Denver Contractors
If you're bidding roofing in Denver, the gap between a job that nets margin and one that doesn't usually comes down to underestimating waste factor for complex roofs — and how you handle heavy snow loads on roofs. Drop a plan set in, walk away for 10 minutes, come back to a priced bid you can defend.
What Denver does to a roofing bid
Cold winters, mild summers, significant snowfall, high UV. Temperatures swing 10°F - 85°F, rainfall runs 15-25 inches (plus heavy snow), and inspectors here are working off IRC R301.2 / IECC Zone 6–7. None of that shows up on a plan symbol legend — but it changes your fastener schedule, your waste factor, and whether the building department signs off on the rough.

Watch-out specific to this market

Stuff Denver roofers ask before they sign up
Does this respect CO code, or do I have to re-cut every quantity?
Counts assume IRC R301.2 / IECC Zone 6–7 (50+ psf snow load, frost depth 60 in., R-60 attic, WUI-rated assemblies in fire zones). CO doesn't license roofing at the state level, so the variability comes from local amendments. Quantities are correct; you adjust crew rates and local permit assumptions in the bid summary.
How do you handle manually counting squares from blueprints takes hours?
The model reads the plan once, counts symbols against your assembly library, and surfaces the count for review. You override anything that looks off before it hits the quote. For residential work in Denver, the typical correction is one or two assemblies — not redoing the whole thing.
