Project Assessment
Determine if your roofing project requires a permit. Consider the scope of work, structural changes, and whether you're replacing materials. Many roofing contractors can help with this initial assessment.

Submit your permit application to Redmond's Building Department. This typically involves completing application forms, paying fees, and providing project documentation. Some applications may be submitted online.
Plan Review
City reviewers examine your application for compliance with building codes, zoning regulations, and energy efficiency standards. This process may take several weeks depending on project complexity.
