Question 1

Does a Bellevue roof replacement need a permit?

Accepted Answer

Bellevue's roofing guidance separates roof recover work from roof replacement and looks at the condition and amount of substrate or sheathing work. The City says a permit is required when roofing includes modifying or replacing sheathing. For a residential roof replacement, its published threshold for repaired or replaced substrate is limited to five 4-by-8 sheets before a building permit is required. Bellevue determines the final path from the complete project scope.

Question 2

How is a Bellevue roof recover different from a roof replacement?

Accepted Answer

Bellevue defines a roof recover as a new roofing layer installed over an existing covering. For residential work, its policy says a building permit is not required unless the added material increases total roof weight by more than 5 percent. A replacement removes existing roofing and can include substrate repair, so it is reviewed differently. The City should confirm the actual material and scope before work starts.

Question 3

What Bellevue sheathing work can affect the permit path?

Accepted Answer

Bellevue's residential roofing policy states that a building permit is not required when repaired or replaced substrate is limited to five 4-by-8 sheets. Its general permit guidance also says roofing that modifies or replaces sheathing requires a permit. Structural conditions, the final amount of work, and related changes can affect the City path, so the completed scope should be confirmed before scheduling construction.

Question 4

How does attic ventilation affect a Bellevue roof replacement?

Accepted Answer

When a roof cavity is exposed, Bellevue's published roofing policy addresses insulation conditions. For a vented assembly, it says a gap must be maintained between insulation and sheathing for air circulation under IRC R806.3. The roof design and final scope determine how the City requirements apply to a particular home.

Question 5

How do skylights or structural changes affect a Bellevue roofing project?

Accepted Answer

Bellevue states that installing or moving an exterior skylight requires a plan-review permit, while a same-size replacement in the same location can have a different path. Changing roof slope or adding dormers also requires plan review. Applications, documents, permit status, and inspection requests are handled through MyBuildingPermit, with required inspections listed on the issued permit.
