The Hottest Roofs in Los Angeles
NOAA's weather station at Pierce College in Woodland Hills averages 35.6 days a year at or above 100°F, against 14.7 at Van Nuys Airport in the central Valley. On September 6, 2020 the Pierce College station recorded 120°F in NOAA's daily record, and the National Weather Service reported 121°F, a Los Angeles County record.
| NOAA 1991–2020 normals | Woodland Hills (Pierce College) | Van Nuys Airport |
|---|---|---|
| Average July high | 95.1°F | 91.2°F |
| Average August high | 97.4°F | 93.1°F |
| Days a year at or above 90°F | 115 | 77 |
| Days a year at or above 100°F | 35.6 | 14.7 |
| Rain a year | 16.4 in. | 13.4 in. |
Heat like this is hard on asphalt shingles and on the underlayment beneath tile, and it's why a cool-rated product matters here: Woodland Hills is Title 24 climate zone 9, where a residential reroof of more than half the roof needs one unless an exception applies. LADWP customers can apply for its cool roof rebate; see the Title 24 cool roof guide.

Permits: LADBS, Usually an Express Permit
Woodland Hills is part of the City of Los Angeles, so the reroof permit comes from LADBS, online or at the Van Nuys Development Services Center at 6262 Van Nuys Blvd. Most reroofs qualify for an Express Permit with no plan check: a Class A or B covering under 6 pounds per square foot over existing or new solid sheathing, a tile lift-and-relay, or a coating. New clay or concrete tile is heavier and goes through plan check. The permit guide and checker walks through it, and the contract should name the contractor as the one pulling it.
What Woodland Hills's Reroof Permits Show
LADBS issued 2,666 reroof permits in the Woodland Hills-Warner Center Neighborhood Council area from 2020 through 2025, about 444 a year, more than any of the other neighborhoods we cover. Roofs run larger than the city norm, a median of 27.5 squares against 23, and 32% of permits were on hillside lots, against 20% citywide.

Two Woodland Hills: the Hills and Warner Center
South of Ventura Boulevard the neighborhood climbs into the Santa Monica Mountains. About half the neighborhood council area is in the Very High Fire Hazard Severity Zone on the City's map, where LADBS requires a Class A roof, and about a third is designated Hillside Area. ZIP code 91364, mostly south of Ventura, is three-quarters single-family houses, and 72% of homes there were built before 1980, with the 1950s the biggest decade.
North of the freeway is Warner Center, a regional center with its own specific plan. ZIP code 91367 is nearly half apartments and condos in buildings of 20 or more units. The Warner Center 2035 Plan asks for a Solar Reflective Index plan on projects that install a new roof, a reflective roof or a partly vegetated one; ask City Planning whether a straight reroof counts as a project before you order materials.

That layer is the 2011 map written into the municipal code; CAL FIRE's 2025 recommended maps are not yet adopted by the City. Check a parcel on ZIMAS or LAFD's fire zone page.

The Mulholland Scenic Parkway Reroof Check
About a sixth of the Woodland Hills neighborhood council area sits inside the Mulholland Scenic Parkway Specific Plan corridors, along the ridge. City Planning's own applicability chart for the plan has a line for re-roofs: they apply to all properties in the plan area, LADBS checks them, and the notes read "All roofs must be non-reflective." Composition shingle, slate and tile are fine; metal works if it's finished in an earth tone or a darker color. The plan itself says roofs visible from Mulholland Drive must be non-glare, and rooftop solar is exempt. If your street is up toward Mulholland, ask about this before choosing a color, especially a bright cool-roof product.
