Fast, Reliable Roof Replacement Across Florence-Graham
Roof replacement in Florence-Graham runs $7,200 – $14,800 for a typical post-war bungalow, with flat-roof additions and single-story re-decks landing between $4,900 – $9,600. That’s the honest range for this neighborhood: small lots, dense tree cover, and roofs that have been patched and overlaid more than once. If you’re weighing whether to repair or replace, call (866) 361-1724 and we’ll give you a straight read on what your roof actually needs, not what’s easiest to sell.
Chatham Roof Repair works throughout Florence-Graham and the surrounding unincorporated pockets of ZIP 90001. Our crews know the streets here: Graham Avenue, Compton Avenue, the narrow blocks south of Slauson where jacarandas hang over every alley. We pull permits through LA County Public Works Building & Safety, which matters more than you’d think when the inspector shows up. Nelson Quarry runs the company, and he’s particular about that kind of thing.
Why Chatham Roof Repair Is Florence-Graham’s Preferred Roof Replacement Company
Florence-Graham is not Los Angeles. It’s unincorporated county territory, and the permitting, inspection, and scheduling paths are different. We’ve spent enough days at the county counter and in 90001 backyards to know what holds up a job and what doesn’t. When a homeowner on a narrow lot off Graham Avenue calls us, they get an answer from someone who knows their street, not a dispatch center three counties away.
Our customers in Florence-Graham tell us the same thing: they want a roofer who shows up, looks at the decking with a flashlight, and tells them whether they need six more months or a full tear-off. That’s how we operate. No pressure. We work from the inspection findings, not a quarterly sales target.
Response time for Florence-Graham calls is typically 24 – 48 hours for estimates. If you’ve got an active leak into a flat-roof addition or a porch tie-in that’s ponding after any rain, mention it when you call and we’ll prioritize accordingly. Roofing is all we do. We’re not going to sell you windows or offer to pour a driveway while we’re there.
Styles & brands we work with






Flat Roof Replacement in Florence-Graham
Flat Roof Replacement in Florence-Graham is the single most common full-replacement job we handle, mostly because so many of these post-war bungalows had flat-roof additions tacked on for garage conversions, rear utility rooms, or rental units. In 90001, these flat sections usually carry torch-down or rolled asphalt over original framing that was never given proper slope. That’s why they pond, leak, and eventually rot the adjacent fascia and rafter tails. A full flat-roof replacement on a Florence-Graham addition or detached garage typically runs $4,900 – $9,600 depending on square footage, decking condition, and how much edge and flashing work the tie-in requires.
County inspection for flat-roof work here follows the same path as any other permit: plans, inspection sequencing, final sign-off through LA County Public Works. We handle it start to finish. What we won’t do is sell you a full flat-roof replacement when the real fix is two new drains and a layer of modified bitumen. That’s the repair-first approach Nelson built the company on.
Garage and Porch Tie-In Repairs
Most flat-roof leaks we find in Florence-Graham happen where the flat section ties into the main shingle roof. The original flashing was thin, the deck shifted over 60 years, and now water creeps under the membrane. We re-flash the tie-in, re-slope using tapered insulation or a lightweight fill, and replace edge metal before it wicks moisture into the rafters.
Ponding Water and Drainage Corrections
Florence-Graham gets maybe 10 – 14 inches of rain a year, but when it comes, it comes in a few heavy winter days. A flat roof with even an inch of standing water is a leak waiting for the next storm. We correct slope, add or relocate drains, and coat with a granular cap sheet that holds up to the long UV season better than smooth torch-down.
Roof Installation in Florence-Graham
Roof Installation in Florence-Graham almost always means tearing off two or three layers of old composition shingle before any new material goes on. Many of these 1920s – 1960s wood-frame homes were re-roofed by overlay because it was cheap and the county allowed it. The problem is that those old layers sit on the original plank decking, and the plank decking has been quietly softening under leaf-litter valleys for decades. A full roof installation with tear-off, new underlayment, and architectural shingles on a Florence-Graham bungalow typically ranges $7,200 – $12,500. Larger homes with complex hip lines or multiple tie-ins run $10,000 – $14,800.
County code in unincorporated LA now requires tear-off to inspect decking in most cases. That’s not a gamesmanship item; it’s a legitimate safety and longevity issue. We’ve opened roofs on these narrow lots and found decking soft enough to push a screwdriver through. Better to find it on a Tuesday in October than on a rainy Saturday in February.
Asphalt Shingle Tear-Off and Re-Deck
When we pull the old layers off a Florence-Graham roof, we check every plank. Anything compromised gets replaced with CDX plywood before new underlayment goes down. It adds a few hundred dollars, but it means the new roof isn’t nailed into rot.
Architectural Shingle Installation
New architectural shingles make sense for almost every roof in this neighborhood. They’re thicker, better at hiding surface imperfections, and hold up longer under the relentless South LA sun than three-tab. The UV here is brutal: dark roofs hit 150 degrees in July and August, and dark 3-tab ages noticeably faster.
Trusted Brands We Service in Florence-Graham
We install and service systems from seven major manufacturers, including GAF, CertainTeed, Tamko, and Boral. That means when a Florence-Graham homeowner asks for a particular shingle profile or warranty class, we can actually source it instead of steering you toward whatever’s overstocked in the yard this month. On properties where only the front slope gets replaced, we match the existing shingle profile and color so the curb side doesn’t look like two different roofs. We stock common valley metal, flashing, and starter strip for jobs throughout 90001, which keeps turnarounds shorter. Whether you’re repairing two squares or replacing the whole roof, the right material for your existing roof is matched in profile and manufacturer coverage.
Common Roof Replacement Problems We See in Florence-Graham Homes
- Jacaranda and ficus litter rotting valleys before shingles fail: Leaf debris packs into every valley and gutter on these tree-canopied streets. Moisture sits against the underlayment and fascia for months, rotting the edges while the field shingles still look okay.
- Overlaid second and third shingle layers hiding bad decking: On a 1950s bungalow, the original plank decking has been through 70 summers. When we tear off two overlays, we often find soft spots and old leaks that never showed from the attic.
- Flat-roof additions ponding because the original slope was never corrected: The rear garage conversion or porch enclosure was built flat and cheap. Water pools after any real rain, and the penetrations and flashing eventually fail under standing water.
- Barely-vented attics baking shingles from below: These original homes have minimal soffit and ridge ventilation. In summer, attic temperatures push 140 degrees, cooking shingles from both sides and causing premature granule loss and curling.

FAQs About Roof Replacement in Florence-Graham
We pull through LA County Public Works Building & Safety. Florence-Graham is unincorporated, so the county handles the permit counter, inspection scheduling, and the final sign-off. We handle that paperwork and sequence the inspections so the job doesn’t stall. Call (866) 361-1724 and we’ll walk you through what your specific property requires.
Because jacaranda and ficus leaves are fine, flat, and sticky when wet. They pack into valleys in layers, trap moisture against the underlayment, and hold it there for months. The decking and fascia rot from the bottom up while the shingles on the open field still look serviceable. A quick valley and gutter clean each spring buys years. When rot’s already started, it needs metal and edge repair before it spreads under the roof.
Usually yes, and it’s cheaper to do them together. The flat section and the shingle roof meet at a tie-in, and working that joint once saves you the cost of a second mobilization and a second permit sequence. If the flat roof has life left, we’ll still re-flash the tie-in while the shingle crew is on-site. Get the exact number by calling (866) 361-1724 for a free estimate.
Look at the line items, not the bottom number. A lower bid often assumes no decking replacement and reuses existing flashings. Any Florence-Graham roof with multiple shingle layers or heavy tree cover probably needs decking work and new edge metal. Ask each bidder how they’ll handle county inspections and whether tear-off is full. The honest contractor lists it. Estimating is free, so call us at (866) 361-1724 if you’d like a second read on an existing quote.
Yes, and they’ll last significantly longer than 3-tab under inland South LA’s sun. Architectural shingles have a thicker, more granulated wear layer and handle thermal expansion better. Pair that with ridge and soffit ventilation and you’ve got a roof that doesn’t bake itself from the inside out. We can show you the difference for your roofline.
What Makes a Florence-Graham Roof Different
On a narrow shared-lot parcel off Graham Avenue, our crew tore off two overlaid layers of composition shingle down to original 1950s plank decking, installed new underlayment and ice and water shield in the jacaranda-clogged valleys, and re-flashed a flat-roof addition tied into the rear garage. The leaf-litter rot had eaten the old drip edge and fascia long before the shingles failed, so we rebuilt both edges with new starter strip and ridge venting to finally move heat out of a barely-vented attic. That’s the standard Florence-Graham failure mode, and it’s exactly why we walk every valley, every tie-in, and every fascia line before we write a quote.
This neighborhood’s rooflines are old, modest, and heavily shaded. Permits go through the county, inspection timing is what it is, and the lots don’t leave much room for staging. You need a roofer who knows how to work within those constraints without pad the invoice for it. Roof Replacement here is less about weather extremes and more about the slow, steady grind of leaf litter, UV, and deferred maintenance on buildings that have simply outlived their original roofing.
