Do You Need a Permit for a Commercial Roof?

In most cases, yes. The Seattle Department of Construction & Inspections (SDCI) requires a permit for commercial roof work that involves:

• Roof replacement (removing and replacing materials)
• Structural modifications (e.g., adding rooftop equipment, changing load-bearing elements)
• Roofing material changes that affect fire resistance or energy efficiency

Minor repairs, such as replacing a few shingles or reapplying a waterproof coating, may not require a permit. However, it’s always best to check with a professional Seattle commercial roofer like Axiom D7 to determine whether your project needs approval.

 

Types of Commercial Roof Permits in Seattle

Seattle issues different types of permits depending on the scope of your roofing project:

1. Construction Permit (Building Permit)

For significant roof replacements, structural modifications, or material changes, you’ll need a Construction Permit from SDCI. This permit ensures your project meets Seattle’s building codes, fire codes, and energy efficiency standards.

2. Trade Permits

If your roofing project involves electrical, plumbing, or mechanical work (such as HVAC units on the roof), you may need additional trade permits.

3. Environmental & Stormwater Permits

Seattle has stringent stormwater management regulations. If your roofing project affects drainage, waterproofing, or runoff, you may need an environmental permit to ensure compliance with the city’s sustainability efforts.

 

Steps to Obtain a Commercial Roofing Permit in Seattle

Step 1: Determine Permit Requirements

Before starting your project, consult with a licensed commercial roofing contractor like Axiom D7. We’ll help you determine whether you need a permit and which type applies to your project.

Step 2: Prepare and Submit Permit Application

The permit application typically includes:
Project details and scope of work
Structural drawings or roofing plans (if required)
Compliance with energy codes and fire safety standards

Step 3: Await Review and Approval

SDCI will review your permit application, which can take anywhere from a few days to several weeks, depending on project complexity. Structural modifications may require additional inspections.

Step 4: Inspections and Final Approval

Once your permit is approved, inspections may be required during and after construction. A final inspection ensures the work meets Seattle’s building codes before the project is officially completed.
