Unincorporated Los Angeles County
Roofing in Acton, CA
Reroofs, repairs and skylight work for Acton homes in the hills south of Palmdale, from a licensed roofer. Free estimates.
Acton is over the hill from Palmdale, down the 14 into the canyon country, with brush on the slopes and more trees than the valley floor. That is why fire is the first word in most Acton roofing conversations. Acton is unincorporated Los Angeles County, and the county's fire zone rules go further than a lot of people expect.
Where a county home sits in a fire hazard severity zone, the roof covering must be Class A, tested to ASTM E108 or UL 790. That rules nothing exotic out; many tile and shingle products carry a Class A rating. What it does rule out is patching a fire zone roof with whatever was in the garage.
Skylights get caught by the same rules. In a fire zone the county wants skylights to be multi-pane units with at least one tempered pane, or glass block, or a 20-minute rated unit. An old single-pane acrylic dome does not meet that, so if you are replacing a skylight in Acton, the new one has to.
The permits themselves come from county Public Works through the Antelope Valley Building and Safety office in Lancaster. If you want us to look at a roof, a leaking skylight or the gutters before fire season, book online and we will come out.
