What Clear Creek County requires, in plain language

Clear Creek County builds to the 2024 IBC and 2024 IRC. That edition, not the newest code published nationally, is the rulebook an inspector in Clear Creek County holds your roof to. Energy work on the same permit follows the 2024 IECC.

Layer limit in Clear Creek County: Only 1 layer permitted. This is the line item that moves a bid the most. If your existing roof is already at the limit, the deck gets stripped before new material goes down, and the labor plus dump fees belong in the written price. Flat roof sections are capped at Only one layer permitted.

Wind is what Clear Creek County tests shingles against. Shingles need a 100 MPH rating. Wind nailing: Yes.

Underlayment and edge metal are where roofs fail inspection. Ice and water shield: Ice barrier required at eaves per IRC R905.1.2. On 2:12 to 4:12 slopes: 19" overlap of 30 pound. On 4:12 and steeper: 15 pound self adhering at eave 2' from exterior wall line. Drip edge: Yes. Minimum drip edge size 2 x 2.

Clear Creek County adopted the 2024 International Residential, Building, Plumbing, Mechanical, Fuel Gas, Energy Conservation and Swimming Pool codes by resolution, along with the 2025 Colorado Wildfire Resiliency Code.
