Fast, Reliable Roof Replacement Across Los Angeles
Roof replacement in Los Angeles typically runs $8,500 – $22,000 for a standard single-story home, with flat roofs and complex tear-offs on the higher end. That range reflects what we actually see across Los Angeles: the bungalow blocks, the dingbat apartments, the hillside homes with steep pitches, and the flat commercial-style roofs that cover so much of the older core. We’re Chatham Roof Repair, roofing-only, based in Inglewood and working across Los Angeles every week. If you’re trying to figure out whether to repair or replace, call (866) 361-1724 and we’ll give you a straight read, not a sales pitch.
Why Chatham Roof Repair Is Los Angeles’s Preferred Roof Replacement Company
Los Angeles homeowners keep calling us for one reason: we look for the repair before we recommend the replacement. Nelson Quarry built this company on that. When we inspect a roof in Los Angeles, the scope of work follows what the inspection finds, not a predetermined upsell path. That matters in a housing stock where a cracked tile or a failing section of built-up roofing doesn’t automatically mean a full tear-off.
We’re roofing-exclusive. No siding, no gutters, no windows. One trade, done with focus. Our seven-brand material roster (GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral) means we can match a replacement or repair to your home’s existing profile, color, and warranty class rather than forcing a single-brand answer. And because we handle inspection, repair, and replacement under one company, there’s no gap between the person who finds the problem and the one who fixes it.
Call (866) 361-1724 and you’ll speak with someone who knows Los Angeles building stock, not a call center.
Styles & brands we work with
Flat Roof Replacement in Los Angeles
Flat roof replacement in Los Angeles is a core part of our work because so much of the city’s housing stock was built with flat or low-slope roofs. These roofs weren’t designed to shed water; they were designed to hold a membrane and let the slope carry water to a drain or scupper. When that slope fails, water pools, and the roof fails early. A typical flat roof replacement in Los Angeles runs $9,000 – $18,000 depending on square footage, decking condition, and the roofing system you choose.
Hot-Mopped Built-Up Roofing
Many Los Angeles homes and small apartment buildings still carry the original hot-mopped tar-and-gravel roof. Decades of UV exposure bake these systems until the surface cracks and the gravel washes away. When we replace one, we remove the old material down to the decking, inspect the framing and slope, rebuild the fall if it’s insufficient, and install a modern multi-ply system with proper flashing at every penetration.
Modified Bitumen and TPO for Low-Slope Roofs
Depending on the building and your budget, we install modified bitumen systems or single-ply TPO on Los Angeles flat roofs. Modified bitumen performs well on older structures where the decking moves with thermal cycling. TPO reflects heat, which matters on a hot Los Angeles summer. Our team walks you through both options, including the warranty difference, before you commit.
Roof Installation in Los Angeles
Roof installation in Los Angeles covers both new construction and full re-roofs on existing homes. If you’re building an addition, converting a garage, or adding an ADU, we handle the roof system from decking through finish material. For existing homes, installation is the second half of a Roof Replacement: tear-off, decking repair, underlayment, then the new roofing system. A full roof installation on an average Los Angeles single-family home runs $8,500 – $15,000 for architectural shingles, and $12,000 – $22,000 when significant decking or framing work is required.
New Construction and ADU Roofing
Los Angeles has seen an ADU boom across the city. When we roof a new ADU or addition, we coordinate with your contractor to make sure the roof ties into the existing structure correctly. This is where a roofing-only company earns its keep: we catch slope issues, flashing details, and drainage problems before they’re buried under finish material.
Architectural Shingle Installation
For pitched roofs on Craftsman bungalows, Spanish Colonials, and hillside homes, architectural shingles are the standard choice in Los Angeles. They hold up to UV better than three-tab, and the dimensional profile matches older architectural styles. We install GAF, CertainTeed, Owens Corning, Atlas, and Tamko architectural shingles, matched to your home’s existing profile and color family.
Trusted Brands We Service in Los Angeles
Chatham Roof Repair installs products from seven major roofing manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. Seven major brands. You choose the product that fits your roof, your budget, and your warranty goals. What that means for Los Angeles homeowners is simple: we’re not steering you toward a single brand because that’s what we carry. We carry all of them. If you need a repair patch, we match the existing shingle in profile and manufacturer coverage so the repair doesn’t look like a Band-Aid and doesn’t void a warranty.

AfterCommon Roof Replacement Problems We See in Los Angeles Homes
- Sun-baked wood shingles and tar-and-gravel decks. The original 1920s-40s roofing materials on Los Angeles bungalows were never meant to survive 80 years of intense UV. By the time a roof starts leaking, the decking underneath is often rotted where water has been sitting for years.
- Sagging flat roofs over converted rear additions. In older South L.A. bungalow blocks, the giveaway is a rear addition with no drainage slope. A previous owner tacked on a room without rebuilding the fall, so the first El Niño storm sends water pooling against the flashing and finding its way inside. This is one of the most common failure points we see in the 90001-90010 ZIPs.
- Santa Ana wind damage at drip edges and valleys. Low-slope and dingbat roofs are especially vulnerable to wind uplift. When the nailing pattern or starter strip was never brought to current L.A. code, the first strong Santa Ana event peels the drip edge back and opens the roof at the valleys.
- Thermal-cycling cracks in flat roofing membranes. The hot inland valleys and cooler coastal edges of Los Angeles create different thermal-cycling rates. A roof in the 90038 area cycles harder than one in a coastal ZIP, which means the membrane cracks sooner and the replacement has to account for that movement.

FAQs About Roof Replacement in Los Angeles
The original bid covers what anyone can see from the roof surface. On older Los Angeles homes, what’s underneath is the unknown: rotted decking, undersized rear-addition framing, or drainage slopes that were never right. A roofer who opens the decking and then writes change orders without warning is doing it wrong. Our approach is different: inspection first, allowances written into the contract, and any framing or waterproofing surprise priced and approved in writing before we touch it. That’s what the allowance is for. If we don’t use it, you don’t pay it. Call (866) 361-1724 for an estimate that accounts for the unknowns before we start.
We tear off the old roof, expose the framing, and rebuild the slope to carry water to the drain. That’s the only fix that lasts. A new membrane over a bad slope fails in the same place at the first big rain. In the 90001 – 90010 bungalow and dingbat blocks, this is routine work for us. The framing upgrade gets priced and approved before we install the new roof system. Call (866) 361-1724 and we’ll walk you through what your rear addition actually needs.
Yes. Los Angeles requires permits for roof replacement, and once the decking is open, the inspector reviews the framing, nailing, and waterproofing against current code. Older homes often need upgraded nailing patterns, improved drainage, or additional decking fastening. We pull the permits, schedule the inspections, and factor the code work into the estimate up front. You won’t be surprised mid-job. Call (866) 361-1724 to talk through what your specific home is likely to trigger.
Compare the line items, not the totals. One bid may include decking replacement allowances, code upgrades, and permit fees. Another may quote a bare number and add the rest as change orders. Look for the allowance language. Look for whether the bidder names the manufacturer and the specific product. Look for whether the slope and drainage work is included or assumed. If a bid seems too clean, ask what happens when the decking is rotted. Our bids are line-item and written, with allowances spelled out, so there’s a fair comparison. Call (866) 361-1724 for a free estimate you can hold up against any other bid.
Yes, if it’s installed to current Los Angeles code with the right fastening pattern, drip edge, and flashing. Santa Ana winds exploit weak nailing at the drip edge and valleys. El Niño rain exploits any slope deficiency and every penetration. We install roofs that meet current L.A. code for wind uplift and weatherproofing, using products from GAF, CertainTeed, Owens Corning, Atlas, Tamko, IKO, and Boral, each with manufacturer coverage that matches the material. The material matters, but the installation details matter more. That’s where the failure happens or doesn’t. Call (866) 361-1724 and we’ll inspect your roof with those failure points in mind.
