Arvada enforces the 2024 IRC, adopted March 24, 2026, and you need a reroofing permit to replace a roof unless you replace no more than 25% of the roofing and no more than 100 square feet in a year. Ice and water shield is now required citywide.
General information, read from the official sources listed below on 2026-10-28. Codes and local policies change, so confirm the rules for your address with the building department before work starts.

What it means for a homeowner reroofing in Arvada
The ice and water shield rule is new in Arvada. Roofs permitted under the old 2018 codes may not have it, so a reroof today can add a line item the last roof did not have.
Highway 93 divides the wind zones. Homes east of it design to 136 mph; homes west of it, closer to the foothills, design to 150 mph. Confirm the shingle rating covers the higher number if your home is west of 93.
Arvada lets you replace only one damaged face of the roof when the shingle manufacturer allows it and the code is met, which can keep a small hail repair from becoming a full roof. The yearly cap of one square without a permit is tight, though, so most real repairs need a permit.
Common inspection failures in Arvada
These are items the building department's own code or handouts say it checks or rejects. No public data ranks how often each one fails, so the order means nothing.

- A Class 1 or 2 wildfire-map property permitted without the plan review.
- Roof not safe or not clear of frost or snow at inspection time.
- Solar panels not removed by the contractor who installed them.
