Glendale replacements turn on three local facts: the age of the house, the zone's cool roof values and the fire map the city has adopted.
Median build year in Glendale
Glendale's median home was built in 1966 (U.S. Census Bureau, ACS 2020-2024). The assessment records layers, deck and pitch, and the scope names an allowance for extra sheathing.
The cool roof rule that applies
Glendale is its own city, outside Los Angeles, which means the state rule governs here and the Los Angeles ordinance does not. In zone 9, a single-family reroof of more than half the roof needs at least 0.20 reflectance after aging and 0.75 emittance, with SRI 16 as the other route for steep slopes. Low slopes must reach 0.63 and 0.75, with SRI 75 as the other route.
Fire class and the permit
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. Ask the fire department which class your covering needs. The Re-Roof building permit is listed on the city's Permit Application Guidance page.
