Roofing inspections requested before 3:30 p.m. will be performed the following business date from the date of the inspection request, understanding that workload and or severe climate conditions could delay the inspection process. Mid-roof inspections will be performed within 24 hours of the requested inspection. A Mid-roof inspection is required on tile, slate, or any roofing material that requires the use of battens.

Where permitted, all wood shakes or wood shingles shall be minimum Class “C” fire-resistance rated. Proof of the Class “C” fire-resistance rating must be provided for the inspector at the time of inspections (tags on shingles or shakes, purchase order, etc.)

Basic Roofing Permits may be submitted online if it is a residential roofing permit, the existing roof type is asphalt composition or masonite product or metal and the replacement roof type must be asphalt composition or metal.  View Douglas County Roofing Fees.
