Columbia County roofing permits & contractor resources

Columbia County publishes a dedicated Roofing Permit Application with roof-installation instructions. It calls for a pre-roof inspection when installing over existing material and disallows a third layer under the cited code. Manufactured-home reroofs are directed to Washington L&I. Washington Roofing Network helps Columbia County homeowners check local roofing resources and prepare a project scope for an independent roofer.

The permit route

Who handles roofing permits in Columbia County?

The county application, revised December 2025, calls for felt, ice shield, and drip edge for shingles and felt for metal roofs. A pre-roof inspection is required for an overlay to assess the existing roof; a third layer is not allowed under its cited code. Right-of-way use may require a separate permit.

What belongs in a Columbia County roofing plan?

The form distinguishes shingle from metal underlayment and flags possible right-of-way permitting for equipment or materials. Identify existing layers and dumpster/access locations before estimating. The source addresses county roofing applications; verify jurisdiction by address and do not extend its terms beyond the stated form.
