New roofs in Glendale are built on additions, units and rebuilds, where the fire map for the address decides the covering.
Where new-roof permits come from
The City of Glendale's own building office issues the permit, within the building permit for the whole structure. Its guidance page lists forms. Roofing inspections follow the sequence the permit sets out.
Class A in fire areas
Glendale's fire department says the March 2025 state maps gave the city Moderate, High or Very High classifications, and that very high zones require Chapter 7A building measures. Fire class belongs to a tested assembly, and vents and eaves need attention. Look up your address on the state map and ask the fire department what the plans must show.
Matching an addition
An addition roof joins the old deck, with underlayment lapped and flashing at the pitch change. Plan the covering to match, subject to what is still made. Where the old roof is old, replace both slopes together.
