Roofing in Granada Hills, Los Angeles

Granada Hills is a neighborhood of the City of Los Angeles in the north San Fernando Valley, south of the Santa Susana Mountains and a short drive from the Santa Clarita Valley. Much of it was built in the 1950s and 1960s, with ranch-style homes on generous lots, including mid-century modern tracts with low-pitched and flat roof sections. Foothill neighborhoods to the north have larger homes on hillsides. Permits go through the Los Angeles Department of Building and Safety (LADBS).

Mid-century roofs and low slopes

Mid-century homes often have low-pitched roofs, flat sections over living areas, exposed beams, and wide overhangs. Those designs need roofing suited to low slopes: modified bitumen, single-ply membranes, or built-up roofing rather than shingles on the flattest areas. Common problems include ponding, seam failures, and leaks at transitions between low-slope and pitched sections. See flat and low-slope roofing.

Are there historic rules?

Part of Granada Hills includes a Historic Preservation Overlay Zone covering a mid-century modern tract. If your home is in an overlay zone, exterior changes such as roofing material may need historic preservation approval from the City of Los Angeles. Check with the city's Office of Historic Resources before you change materials or profiles.

Shingle roofs over old decking

Many ranch homes started with wood shake roofs. Later shingle roofs may sit on skip sheathing that needs solid decking added during a re-roof. Pre-1978 homes may have lead paint on fascia and eaves, and some older roofing materials may contain asbestos. See shingle roofing.

Foothill fire risk

Neighborhoods near the foothills and open space, including areas near O'Melveny Park, are often mapped as fire hazard severity zones. In a mapped zone, re-roofs generally require a Class A assembly and ember-resistant vents. Look up your address on the CAL FIRE Office of the State Fire Marshal maps and see fire-resistant roofing.

Mature trees

Large, older trees shade many Granada Hills roofs and drop leaves into gutters and valleys. Keep branches trimmed back and gutters clean, especially before the rainy season and Santa Ana wind events.

ADUs

Granada Hills lots are often large enough for ADUs. New ADU roofs should be permitted and, in fire zones, meet the same fire rules as the main house.
