Roof replacement and repair in Porter Ranch
Porter Ranch was the last part of the San Fernando Valley inside Los Angeles city limits to be developed, with major construction starting in the 1970s. Much of it is master-planned, and today it is mostly gated communities of single-family homes.
Homeowner associations in planned communities commonly set rules on roof material and color. Check your association's rules before you choose, and we will prepare what its review asks for.
Porter Ranch lies in the hilly northwestern tip of the Valley, where winds sweep through regularly and have been clocked at 70 mph. In a windy location the way the roofing is fastened matters as much as the material.
Roofing permits in Porter Ranch
Porter Ranch 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.
