What Parker requires, in plain language

Parker builds to the 2024 IBC and 2024 IRC with the 2024 Parker Administrative Code. That edition, not the newest code published nationally, is the rulebook an inspector in Douglas County holds your roof to.

Layer limit in Parker: One layer. 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 One layer.

Wind is what Parker tests shingles against. Shingles need a SFD - 115 MPH (90 MPH, 3 second gusts, exposure C): Commercial - please contact rating. Rating is proven under ASTM D 7158 or ASTMD 3161. Wind nailing: Yes, 6 nails per shingle.

Underlayment and edge metal are where roofs fail inspection. Ice and water shield: No. On 2:12 to 4:12 slopes: 19" overlap of 15#. On 4:12 and steeper: 15# manufacture requirements may be more stringent check requirements. Drip edge: Yes. Minimum drip edge size 2×2 minimum or large enough to cover any gaps from original construction.

Parker Town Council approved the 2024 International Building Codes with an effective date of June 30, 2026, along with a 2024 Parker Administrative Code.
