Based on Los Angeles's local building codes, you'll need a permit when:
A full roof replacement (re-roofing) requires a building permit. California limits re-roofing to a maximum of two layers of roofing material. If the existing roof already has two layers, a full tear-off is required. Cool roof requirements (Title 24) may apply.
Changing roofing material type (e.g., composition shingles to tile, or to metal) requires a building permit. The new material may have different weight requirements that affect the structural capacity of the roof framing. A structural review may be needed.
Any roof work involving structural modifications (adding skylights, changing roof pitch, adding dormers, modifying trusses or rafters) requires a building permit with full plan review. Engineered plans are typically required.
These roof replacement projects are typically exempt in Los Angeles:
Minor roof repairs (patching, replacing a few shingles, fixing flashing) that do not involve structural changes are generally exempt from permits. This applies to repairs covering a small area of the roof without changing the roofing material type.
