A full roof replacement on a typical Los Angeles house runs 12,000 to 40,000 dollars and takes three to seven working days.
At a glance
- Price follows the material, the pitch, and how many layers come off.
- Tile roofs often keep the tile and get all new underlayment.
- The city needs a permit and at least one inspection.
- Get the deck looked at before anyone quotes a number.
When a roof is done
Asphalt shingles in this sun last about twenty years. Underlayment under clay or concrete tile lasts twenty to thirty. A flat roof coating lasts ten to fifteen. Once a roof passes those marks, repairs stop holding and the smart money goes into a new system.
Other signs are granules filling the gutters, shingles that curl at the corners, soft spots underfoot, and daylight in the attic.
The tile roof shortcut people miss
Clay and concrete tile can last a hundred years. The felt under it cannot. On thousands of homes across the San Gabriel Valley the right job is a lift and relay. The crew takes the tile off by hand, stacks it, replaces the underlayment and flashing, then sets the same tile back down.
A lift and relay costs less than new tile and keeps the look of the street. Ask every bidder to price it that way before you agree to a full tear off.
What the crew does day by day
Day one is tear off and deck repair. Day two is underlayment, drip edge and flashing. Day three and four are the roof material itself. The last day is cleanup, a magnet sweep for nails, and the city inspection.
Rain, a steep pitch, or a second story slows all of that down. A crew that promises a full roof in one day on a large home is cutting something out.

Common questions
Do I need a permit for a new roof in Los Angeles
Yes. Los Angeles and every city in the county require a permit for a reroof, and the permit is pulled by the licensed contractor.
Can a new roof go over the old one
Code allows one overlay on shingles in some cases, but it hides deck damage and shortens the life of the new roof. Most good roofers will not do it.
How much does a roof add to a home sale
A new roof rarely returns its full cost, but a bad roof kills deals and lands as a large credit at closing.
