A new roof in West Hollywood sits inside a building permit for the structure.
Permits for new roofs
The city's own Building and Safety office issues the building permit that carries the roof. Roofing inspections are one stop in the sequence the permit sets out. Ask the office which inspections it wants before the covering goes on.
Title 24 on new roof work
A new roof is all new work, and the permit office decides how the Energy Code applies to it. The 2025 code has been in force since 1 January 2026. Ask the building office which cool roof values apply to your plans, since they depend on slope and climate zone 9.
Matching an addition to the existing roof
The new deck joins the old one, with underlayment lapped over the seam and flashing where pitches change. If the old covering has few years left, replacing both slopes together removes the seam. Color and profile matching depends on whether the old product is still made.
