Questions covered in this guide
Local considerations
Portland’s roof-permit exceptions distinguish townhouses, mapped wildfire settings, and building-integrated photovoltaic coverings. A three-part scope card lets the applicant resolve these separate conditions before a homeowner relies on a general reroof exemption.
The scope card treats Portland’s townhouse, wildfire, and integrated-solar distinctions as separate decision inputs. It prevents a general reroof exemption from being applied before the actual building and product are identified.

Portland’s residential guide identifies townhouse reroofing, dwellings in Wildfire Zones, and building-integrated photovoltaic coverings as permit-required cases. Those distinctions matter before applying a general reroofing exemption to your project.
Verify the property category
Confirm the address’s permitting authority and the building classification with the applicant. Do not treat a Portland mailing address, shared wall, or familiar neighborhood name as proof of jurisdiction or building type. Ask how the city identifies the applicable wildfire designation. Record the response and supporting property information so each roofing bidder works from the same scope assumptions.
Prepare a three-part scope card
Make separate entries for building type, location designation, and proposed roof covering. In the covering entry, distinguish ordinary roofing with a separate solar installation from a proposal that uses photovoltaic roofing as the covering itself. Ask the designer or roofer to identify the actual product and coordinate any solar professional. Add an unresolved-question column rather than choosing the nearest-sounding product category. Have the applicant state which permit route follows from the completed card.
Keep later product changes connected to review
If you change from conventional roofing to an integrated solar product, return the scope card to the applicant before ordering. Ask whether the revised choice changes drawings, trade coordination, or the city review. This guide does not decide the exemption for a particular address or authorize work without permits. The national roof calculator cannot price Portland permitting or integrated solar roofing. Use it only for preliminary planning, then request a project-specific proposal that reflects the confirmed building category and selected roof system.
