Composition shingle, and what the sun does to it. Composition roofs across Los Angeles, including wind damage that is invisible from the ground.
Free inspection, the deck and layer count established, then a written quote.
Steep-slope cool-roof requirements run in climate zones 10 to 15, and Los Angeles sits in 6, 8 and 9. A pitched shingle roof here is generally outside them, so a quote charging for a cool-roof upgrade on one is worth questioning.
Composition shingle is the most common covering in the Valley and the one the climate is hardest on. Ultraviolet light drives the volatiles out of the asphalt, the mat goes brittle, and the granules that were protecting it wash into the gutter.
Composition repairs run $350 to $1,500 in Los Angeles. Where a whole slope has gone, replacement is $7 to $11 per square foot - and on this housing stock a slope does tend to finish all at once rather than in patches. In the city the permit is part of the price. Re-roofing is permitted work through LADBS, and once more than half the roof area is being replaced the energy-code requirements come with it - on a low-slope roof that means a cool-rated product and an aged SRI of 75 or higher.
A creased shingle drops back flat and looks intact. Caught now it is a repair; found in January it is a ceiling.
We will tell you honestly which one you have. A bald section usually means the slope is finished, not damaged.
Two layers is the practical legal limit. If you are already at two, the next job is a tear-off whatever anyone quotes.
Work in the city is permitted through LADBS and has to meet the Title 24 cool-roof requirements where they apply. That is not a detail to discover after the tear-off.
A shingle roof here does not usually fail in one place. It reaches the end of its life across a whole slope at once, which is why an honest assessment sometimes says replace rather than repair.
All roofing work in Los AngelesWorth knowing before you start ringing round, and worth factoring into anything with a deadline on it.
Contractor backlogs across Los Angeles have run four to twelve weeks through 2026, with labor rates 15 to 25% above where they were before the Palisades fire. Materials are up about 6% on last year and LA County labor another 8 to 12%.
What that means in practice: an active leak needs calling now rather than on the weekend, and anything tied to an escrow date or a solar install needs a survey booked well before you think you need it. Emergency call-outs carry a 20 to 30% premium for a reason - everyone is busy.
A leak repair does not usually need an LADBS permit, but the line between a repair and a re-roof is a real one: once more than half the roof area is involved, the energy code requirements come with it.
Re-roofing in the city is permitted work through LADBS, and the permit brings an inspection.
A tile lift and relay does not change the covering, so it does not usually trip the energy-code thresholds a replacement would.
Low-slope is where the energy code actually bites in Los Angeles: cool-roof requirements for low-slope roofs apply statewide, in all sixteen climate zones.
The figure the city cares about on a low-slope replacement is aged solar reflectance index, and the threshold to clear is 75 or higher.
Bungalows and low-pitch ranch, plus butterfly roofs.
Newer tracts, and most of the tile in this market.
Rambling single-story ranch, long runs, wide eaves.
Post-war west Valley. Surveyed before anything is quoted.
Big lots, outbuildings, and a Very High fire zone.

The questions that decide a job, answered before you ask.
Yes, and it is a cheap check. Santa Ana damage is close to invisible from the ground - the shingle creases at the seal line and drops back flat. It leaks in the first driving rain after, which can be months later when nobody connects the two.
Be careful what that tells you. Composition here tends to finish across a whole slope at once rather than in patches, so a bald section usually means that slope is done. We will tell you which one you have rather than selling you a patch that fails.
Because most online figures are national. Asphalt shingle is about $8.50 per square foot here against roughly $4 nationally, and LA County labor is up 8 to 12% on last year. A quote that matches a national average is usually missing something.
For a full replacement in LA County, an estimated $10,000 to $25,000 covers most houses, and repairs usually run an estimated $350 to $1,500. The honest answer is that the range is wide because pitch, access, covering and what the old roof was hiding all move it - which is why the inspection is free and the quote is written down before any work starts.
Roofing in California requires a CSLB C-39 license, and the number is public - ask for it and check it on the CSLB register before anyone sets foot on your roof. Do that with every quote you get, not just this one.
Free inspection, written quote, and we will tell you if the cheaper option is the right one.
