Where roofs leak
Most leaks start at a joint, not in open roof: chimney flashing (1), vent pipe boots (2), skylights (3) and the eave edge (4). Each is rebuilt when we re-roof.

West Hills roofing questions
Do I need a permit to re-roof a house in West Hills?
Re-roofing in West Hills is permitted through the Los Angeles Department of Building and Safety. LADBS issues a standard re-roof as an express permit with no plan check. We pull the permit and meet the inspector for you.
Does a new roof in West Hills have to be Class A fire rated?
Only if your address is inside a Very High Fire Hazard Severity Zone, where LADBS requires Class A roofing. The boundary goes parcel by parcel, so we check your address on the state map. Many asphalt shingle, tile and metal roofs are Class A rated in any case.
What makes a roof more resistant to wildfire embers?
A roof covering and underlayment listed together as a Class A assembly, metal edge flashing, closed gaps at the eaves and ridge, and ember-resistant vents in place of open mesh vents. We go through each of these with you for a home near the hills.
