What Park County requires, in plain language

Park County builds to the 2018 IBC and 2018 IRC with county revisions and exemptions. That edition, not the newest code published nationally, is the rulebook an inspector in Park County holds your roof to.

Layer limit in Park County: 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 Park County tests shingles against. Wind nailing: Yes.

Underlayment and edge metal are where roofs fail inspection. Ice and water shield: Yes. On 4:12 and steeper: Per Code. Drip edge: Yes. Minimum drip edge size Per Code.

Park County adopted the 2018 building code by resolution with county revisions and exemptions. Confirm with development services whether a newer edition has been adopted before you rely on the 2018 provisions.

Installation details above come from our building department field survey for Park County, last updated 1/3/19. Code editions and contacts are refreshed from the department directly. Always confirm the details on your permit before work starts, since departments amend requirements on their own schedule.
