Re-Roof Permit

What is it?

You need a re-roof permit when you are repairing an area greater than 500 square feet or replacing roofing materials on commercial and multifamily projects. A re-roofing permit is not required for one- and two-family homes and townhouses. You need a re-roofing permit if you are replacing the roof cover, sheathing, or insulation. You are required to get this permit so we can verify that your project complies with the energy code requirements. You need to add insulation to meet current energy code standards when the existing roof sheathing or insulation is exposed or the existing roof cavities are not insulated.

How Much Does It Cost?

We charge a flat fee for re-roof permits. It costs half of our base fee plus the state surcharge. All fees are subject to an additional technology fee. See our Fee Subtitle for details.

How Long Does It Take?

We issue re-roofing permits on the same day that you apply online.

Start your application. Complete the Building & Land Use Pre-Application online using the Seattle Services Portal.  Once you're logged into the Seattle Services Portal, create a new Trade and Construction Permit. Select a Re-roofing Permit from the Building Permits section. Then follow the steps to complete the application. 

Complete the contractor disclosure information. To complete this portion of the application you will need the contractor information and owner information. You must provide this information before we will issue your permit.

Pay fees. Fees are due when you submit your application. The fees are calculated based on your project value. 

Print you permit. Please have your permit on-site for inspections. 

Close your permit. An on-site inspection is not required for a re-roof permit. To close and final your permit, fill out the “Affidavit-Roof Replacement” and email the completed document to
