Roof replacement and repair in Granada Hills
Granada Hills was founded in the 1920s on former ranch and orchard land and is made up mostly of mid-century modern homes. It includes Balboa Highlands, a 1960s tract of 108 modernist homes by Joseph Eichler that became a Historic Preservation Overlay Zone in 2010.
Eichler homes and many other mid-century designs have flat or low-slope roofs, which need a sealed membrane system and correct drainage, not shingles or tile. Exterior work inside a Historic Preservation Overlay Zone can need review by the city before a permit is issued, so tell us if your home is in Balboa Highlands.
Roofing permits in Granada Hills
Granada Hills is part of the City of Los Angeles, so re-roofing permits come from the Los Angeles Department of Building and Safety (LADBS). LADBS issues a standard re-roof as an express permit, which does not go through plan check. We pull the permit and meet the inspector.

Flat roofs have to drain
A flat roof is a sealed membrane with a slight slope to its drains. Where water stands, we rebuild the slope before the new membrane goes on.

How embers reach a roof
Wind-blown embers start most roof fires. They land on the roof surface (1), blow in through vents (2) and collect in gutters (3). A Class A roof and ember-resistant vents deal with all three.

Granada Hills roofing questions
Do I need a permit to re-roof a house in Granada Hills?
Re-roofing in Granada Hills is permitted through the Los Angeles Department of Building and Safety. LADBS issues a standard re-roof as an express permit with no plan check. We pull the permit and meet the inspector for you.
Does a new roof in Granada Hills have to be Class A fire rated?
LADBS requires Class A roofing inside a Very High Fire Hazard Severity Zone. The Los Angeles Fire Department lists Granada Hills among the communities in that zone, but the boundary goes parcel by parcel, so we check your address on the state map before we specify the roof.
Can you re-roof an Eichler or another flat-roofed mid-century home?
Yes. Flat and low-slope roofs get a membrane roof system, and we correct the slope where water stands. If the home is in the Balboa Highlands Historic Preservation Overlay Zone, we check with the city whether the work needs review first.
