What's hard on roofs around Granada Hills
Eichler rooflines in Balboa Highlands
Balboa Highlands Eichlers have three main rooflines: flat, sloped and A-frame, originally over two-inch redwood decking on exposed beams. Flat and low-slope roofs need membrane or foam systems rather than shingles, and seams around skylights and beams need careful sealing. As a historic district, exterior changes there go through city review.
Fire risk in the foothills
The 2008 Sayre Fire threatened the Knollwood community, and the 2019 Saddleridge Fire, pushed by Santa Ana winds, threw embers across Interstate 5 toward Granada Hills and Porter Ranch. Part of that fire burned in a Very High Fire Hazard Severity Zone, where Class A roofs and clean gutters matter.
Citrus and mature trees
Old citrus and decades-old shade trees fill Granada Hills yards. Leaves and fruit collect in valleys and gutters, and branches scrape shingles in the wind. In the fire zone, the Los Angeles Fire Department also requires trees to be kept five feet above roof surfaces.
Mid-century roofs at the end of their run
Most Granada Hills homes date from the post-war decades, and homes that age have usually been re-roofed at least once. Additions from later remodels are common, and each joint between old and new is a likely leak point. A licensed roofer checks the deck and the transitions, not just the shingles.
Newer homes need roof care too: tiles and shingles shift in wind, and flashing around vents and skylights is where leaks often start.
