A roof replacement here starts with the house. The median home in North Hollywood was built in 1965 (U.S. Census Bureau, ACS 2020-2024), and the deck under the covering is read before anything new goes on. A hip roof slopes on all four sides, which means the hips and the ridge have to meet cleanly.
The permit is a City of Los Angeles one
North Hollywood sits inside the City of Los Angeles, so the permit office is LADBS. A re-roof with a Class A or B covering on solid sheathing at under 6 lb per square foot qualifies for an express permit and skips plan check (LADBS, 2026). Permits are issued online, or by appointment at a LADBS counter such as Van Nuys (LADBS, 2026).
The City's cool roof step starts at more than 50 percent of the roof. Lifting tile, laying new underlayment and setting the tile back is a separate express permit item without it (LADBS, 2026).
Heat and the cool roof rule
North Hollywood is in climate zone 9 (California Energy Commission, 2022). Under the City rule a steep roof needs 0.25 aged reflectance and 0.85 emittance, or SRI 20, once the job replaces more than half the roof (LADWP, 2022).
For zone 9 the state value on a steep roof is 0.20 reflectance and 0.75 emittance (California Energy Commission, 2022). We read both and build to the stricter one.
Fire class and the one-year rule
Check the address on the CAL FIRE map viewer. Class A is required where a City of Los Angeles address falls in a Very High Fire Hazard Severity Zone (LADBS, 2026).
Re-roof more than 50 percent in a year and the City of Los Angeles asks the whole roof to meet current code. Stay at 50 percent or less and only the new part must (LADBS, 2026). We plan the scope around that line.
Reroof questions for North Hollywood
Which coverings suit a house in North Hollywood?
Tile, shingle, metal and flat membranes can all work in zone 9 when the color and finish are chosen for the sun. On a hip roof, tile shows its lines well. Cool rated tile can meet the state value of 0.20 and 0.75 (California Energy Commission, 2022).
What cool roof rule governs a reroof in North Hollywood?
The City of Los Angeles rule applies once more than half the roof is replaced, with aged reflectance 0.25 and emittance 0.85, or SRI 20, for a steep slope (LADWP, 2022). The state asks 0.20 and 0.75 for zone 9 (California Energy Commission, 2022).
Is Class A needed for a reroof in North Hollywood?
The map settles it. Look up the address on the CAL FIRE map viewer. Under City of Los Angeles rules, Class A is required in a Very High zone. Fire District No. 1 allows Class A or B; anywhere else, Class A, B or C will do (LADBS, 2026).
