Roof replacement and repair in Northridge
Northridge's citrus groves were replaced with housing tracts as World War II veterans moved into the area, and most single-family homes here are original or modified tract homes from that era. Larger apartment and condominium buildings came later, many of them serving students at California State University, Northridge.
Homes of that age have usually been re-roofed more than once. Before we price a replacement we check how many layers are on the deck and what shape the original sheathing is in.
The January 17, 1994 Northridge earthquake damaged thousands of buildings and homes in the area. Where a chimney or a section of framing was rebuilt afterward, we look closely at how it meets the roof.
Roofing permits in Northridge
Northridge 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.
