AA California Roofing handles roof replacement in Los Angeles for homes and businesses: we tear off the old roof, repair the deck where needed, install the new shingle, tile or flat roofing system, take care of the city permit and clean up. We hold California contractor license CSLB #1147688 (C-39 Roofing), and the estimate is free.
To book an inspection, fill in the booking form on our contact page (we work Sunday to Friday, 8 AM to 8 PM). Our office is in Woodland Hills, and we replace roofs across Los Angeles County and in the Ventura County cities of Simi Valley, Thousand Oaks, Moorpark, Camarillo and Oxnard.
New roofs we have installed, from tear-off to the last ridge cap. Open a project to see every photo and what we did.
A repair fixes one failure. Replacement makes sense when the failures are spread across the roof, because the next leak is already forming somewhere else. These are the signs we look for during an inspection:
When the signs are mixed, start with an inspection. Our roof repair service covers what a repair can fix and when it stops being worth it, and our repair-or-replace guide walks through the decision step by step.
We install three roofing systems. Each one is replaced differently, and each meets the Los Angeles rules in its own way.
| Roof type | Where it fits | What the replacement involves | Code points |
|---|---|---|---|
| Asphalt shingle | Pitched roofs (2:12 or steeper) on most house styles | Tear-off to the deck, new underlayment, drip edge, valley metal and flashings, new shingles and ridge | A re-roof covering under 6 pounds per square foot is on the LADBS express permit list; cool-rated shingles meet the Title 24 rules where they apply |
| Tile (clay or concrete) | Spanish, Mediterranean and ranch-style homes | Tiles lifted and stacked, new underlayment and flashings, tiles reset with broken ones replaced; or a change to new tile | LADBS lists removing tiles, laying new underlayment and resetting them as an express permit, with no cool-roof compliance required |
| Flat or low-slope torch-down | Roofs pitched under 2:12: additions, garages, flat-roof homes, apartment and commercial buildings | Old membrane removed, deck repaired, base and cap sheets torch-applied, flashing at parapets, drains and equipment | The 2025 Energy Code sets reflectance rules for low-slope re-roofs in climate zones 4 and 6 to 15, and roof insulation rules in zones 8 to 16 |
Flat roofs have their own failure points (ponding water, seams, parapet walls), explained on our flat roof repair and torch-down page. For clay and concrete roofs, our tile roofing page covers tile types, underlayment and repairs.
Customers notice the communication as much as the roof. One Google reviewer wrote that the team “contacted my Husband and I daily with updates”, and another (in a review Google translated) wrote that Amit “took care of the permit quickly.”
Sometimes. The California Residential Code (Section R908.4 in the 2025 edition) does not allow new roofing over an old roof that already has two or more layers, is water-soaked or deteriorated, or is slate, clay, cement or asbestos-cement tile. That leaves a shingle recover only over one sound, dry layer. Even then the Energy Code counts the new layer as a roof replacement when it covers more than half the roof, and only a tear-off lets the deck be seen and repaired before the new roof goes on.
The City of Los Angeles, which includes Encino and Woodland Hills, repeats the same three limits in its own reroofing section (LAMC 91.1512.3, in force since December 31, 2025), and either kind of job needs an LADBS permit, as our guide to how the re-roof permit works in Los Angeles explains. A recover can only happen once: it leaves two layers, nothing more may go on top, and the next re-roof removes both down to the deck.
If a bid offers new shingles over the old ones, check these points before you sign:
| What is on the roof now | Can new roofing go on top? | 2025 California Residential Code |
|---|---|---|
| One layer of asphalt shingles, dry and sound | Yes, where the new shingle’s installation instructions allow it | R908.4 |
| Two or more layers of any roofing | No: every layer comes off down to the deck | R908.4 and R908.3 |
| A water-soaked or deteriorated roof | No, whatever the layer count | R908.4 |
| Clay, cement or slate tile | No. Sound tile may be reinstalled; damaged, cracked or broken tile may not | R908.4 and R908.5 |
| Torch-down, built-up or another flat membrane | Under the state code, a new protective roof coating may go on without a tear-off. The City of Los Angeles section names only spray polyurethane foam roofs for that, so ask LADBS before counting on it. A new membrane on top meets the same limits as above | R908.4; LAMC 91.1512.3 |
Three sets of rules can apply to reroofing here: the city’s permit, the fire rating of the roof covering, and California’s Energy Code (Title 24, Part 6). Most homeowners only meet them once, so here is how they work.
The LADBS express permit bulletin (P/GI 2026-003, effective January 1, 2026) lists a re-roof with a Class A or B roof covering weighing less than 6 pounds per square foot, over existing or new solid sheathing, as work that needs no plan check. Express permits are issued online or by appointment at the LADBS counters, which include Van Nuys and West Los Angeles. A heavier covering is not on that list, so switching to a heavier material needs a closer look before it is priced.
Inside a Very High Fire Hazard Severity Zone, the same bulletin requires a Class A roof covering. We check whether the address sits in a mapped zone before choosing materials, because it narrows the product list.
Under the 2025 Energy Code, which applies to permits applied for on or after January 1, 2026, the cool roof rules start when more than 50 percent of a home’s roof is replaced, and a new layer laid over the old one counts. For a pitched roof (2:12 or steeper) in climate zones 4 and 8 to 15, the new product needs an aged solar reflectance of at least 0.20 and a thermal emittance of at least 0.75, or a Solar Reflectance Index of at least 16, as rated by the Cool Roof Rating Council (CRRC).
The zone depends on the address. On the Energy Commission’s ZIP code list, Woodland Hills, Tarzana, Northridge, Burbank and Pasadena fall in zone 9, Santa Monica, Torrance and Long Beach in zone 6, and Lancaster and Palmdale in zone 14. The state’s pitched-roof rule does not apply in zone 6, but inside the City of Los Angeles the LADBS bulletin calls for a CRRC-labeled cool roof product on any residential replacement of more than half the roof.
The state code accepts other measures in place of a cool product on a pitched roof: at least R-38 ceiling insulation, a qualifying attic radiant barrier, R-2 or more continuous insulation above or below the deck, or, in zone 9 and a few other zones, no ducts in the attic. We check which of these your house already meets before recommending a product. Our cool roof requirements guide covers the rules in full, and our Los Angeles roofing permit guide covers the paperwork.
We put the schedule in the written estimate instead of quoting a general number, because the time depends on things we can only see at your house:
You can usually stay at home during the work. Expect noise during tear-off, and keep cars out of the driveway while debris comes down.
Yes, between storms. At the downtown Los Angeles (USC) weather station, about 87% of a normal year’s rain, 12.42 of 14.25 inches, falls from November through March, yet those five months average only about 26 days with measurable rain (NOAA climate normals, 1991 to 2020). So a winter tear-off is planned around the forecast rather than put off until spring.
Before the work starts, ask how much roof comes off each day and how open areas are covered overnight if rain moves in. If the roof leaks now, ask our roof repair service about a temporary repair until a dry stretch. The schedule for your house goes in the written estimate, set by its size, layers, deck repairs and permit route.
| Month (USC station) | Normal rain (inches) | Days with measurable rain |
|---|---|---|
| November | 0.78 | 2.8 |
| December | 2.48 | 5.5 |
| January | 3.29 | 6.1 |
| February | 3.64 | 6.3 |
| March | 2.23 | 5.1 |
We do not publish prices, because two roofs of the same size can need very different work. A fair estimate prices these items one by one, and comparing bids line by line on them shows whether two contractors are quoting the same job:
Our roof replacement cost guide explains each factor in more depth. The contractors board’s advice holds too: compare written bids built on the same scope, and be wary of one far below the others, since it may leave out work the others included.
Financing options, when offered, are subject to third-party lender approval. Our roof financing page explains how that works, what to have ready and what to ask a lender before you sign.
Material warranties are provided directly by the manufacturer and are subject to the manufacturer’s terms. Workmanship warranties, if applicable, will be clearly defined in your written contract.
