Do I need a permit for roof replacement or repair in Arvada?
Yes. In Colorado, roof replacement or repair generally requires a permit, and Arvada is no exception.
Because Colorado has no statewide building code, whether a reroof needs a permit and which IRC edition applies is set by your city or county, but most jurisdictions require a building permit to re-cover or tear off a roof. In mountain and foothill areas, roofs must meet local snow-load design and, in wildland-urban-interface zones, ignition-resistant (often Class A) roof-covering rules; confirm both with your building department before choosing materials. Arvada requires a reroofing permit to replace a roof. You can skip it only when replacing up to 25 percent of the roofing, not to exceed 100 square feet, with a maximum of 100 square feet per year. Asphalt shingles in Arvada must be Class 4 impact resistant and tested to UL 2218 (City Code Sec. 18-191). The building official may approve the highest available class when matching existing shingles, and repairs of 100 square feet or less may use the same or similar materials. An ice barrier (ice and water shield) is required, slopes from 2:12 to 4:12 need double underlayment, and T-lock shingles are no longer allowed for new installation. Roofs must be installed for 136 mph (ultimate) east of Highway 93 and 150 mph west of Highway 93. Roofing must have a Class A fire rating in wildfire zones, and Class B may be permitted elsewhere. A new covering may go over an existing one only where 2024 IRC Section R908.4 allows it. Spaced sheathing may be reused if the gaps are no more than 1/2 inch and the boards are sound. For inspections you must provide a duty-rated ladder extending at least 3 feet above the roof edge, because city inspectors cannot set up ladders.
