Fast, Reliable Roof Repair Across Florence-Graham
Roof repair in Florence-Graham usually costs between $350 and $1,800, depending on whether you’re dealing with a flat-roof patch, a shingle replacement, or a parapet flashing failure. Most jobs on the post-war bungalows and duplexes here involve low-slope or near-flat composition roofs, and we’re in and out in a day or two once the permit clears. If you’ve noticed a water stain on your ceiling or granules piling up in a gutter, call us at (855) 382-1073 and we’ll give you an honest assessment of what actually needs fixing.

We know Florence-Graham. The tightly packed blocks off Florence Avenue and Graham Avenue, the 1920s stucco cottages near 92nd Street, the duplex clusters along the major corridors. These homes have specific problems that a roofing company from across town won’t recognize on first look. Our Roof Repair team works throughout ZIP 90001, and we’re familiar with the County’s permit requirements before we ever lift a shingle.
Key Takeaways for Florence-Graham Homeowners
- Flat roof repair in Florence-Graham typically runs $350 – $900 for recoating and patching; shingle repair runs $400 – $1,800 depending on decking condition.
- Almost every roof repair that opens the decking here requires an LA County permit and inspection, not City of LA. We handle that process end to end.
- Shared parapet walls between adjacent bungalows and duplexes mean your leak may actually involve your neighbor’s flashing. We know how to sequence that repair.
- We offer repair as a core service, not a stepping stone to selling you a replacement. If your roof needs a patch, that’s what we’ll tell you.

Why Barnwood Roofing Is Florence-Graham’s Preferred Roof Repair Company
Walk down any block off Graham Avenue and you’ll see it: roof after roof of sun-baked composition shingles and cracked elastomeric coating. We’ve worked on enough of these homes to know what’s under the surface before we open anything up. Ruben Calloway built this company on a simple standard: tell the homeowner what the roof needs, not what pads an invoice. That matters in Florence-Graham, where the housing stock is aging and the last thing anyone needs is a contractor pushing a full re-roof when a $600 patch would do the job.
Our repair crews work throughout Florence-Graham regularly. We know the County inspection process for unincorporated territory, and we know that opening a small soft spot on a bungalow often reveals decking that’s been soaking for years. When that happens, we price the repair in writing before we touch the framing. No change orders sprung on you at the end. No vague allowances. A line-item quote signed before the saw comes out.
Homeowners here tell us the same thing, whether we’re working near 92nd Street or over by the industrial edge along Alameda: they’ve had someone take a look at a leak and come back with a replacement quote for the whole roof. We don’t work that way. We carry materials and parts from seven manufacturers including IKO, Atlas, and Tamko, so when we recommend a patch, a re-coat, or a repair, the product actually fits your home and your budget.
Flat Roof Repair in Florence-Graham
Flat Roof Repair in Florence-Graham is the most common call we get, and it’s usually triggered by a wet spot on a ceiling after one of the rare winter storms. Most of these roofs are original composition or built-up surfaces on 1920s-to-1950s bungalows with shallow pitch or near-flat decks, and the intense inland sun oxidizes the coatings until seams split and water finds a path. A standard flat roof patch, re-coat, or seam repair in Florence-Graham runs $350 – $900, depending on how far the coating has cracked and whether the decking underneath is still sound.
Recoating and Seam Sealing
The sun is the real enemy here. UV breaks down flat-roof coatings fast, and once a seam opens along a scupper or at a wall-to-roof junction, water sits and works its way sideways. We scrape back the failed coating, seal the seam with fabric reinforcement, and re-coat with a UV-reflective white elastomeric that makes a real difference on a south-facing Florence-Graham roof.
Parapet and Drainage Repairs
In the tightly packed blocks off Florence and Graham avenues, low-slope roofs on adjacent homes often share parapet walls and drain toward neighboring lots. That means a leak on your side can actually start in your neighbor’s flashing. We assess where water sheds and where the wall-to-roof detail has failed, then quote a repair that stops the water at the source, whether that’s one property or a coordinated fix across the shared wall.
Shingle Roof Repair in Florence-Graham
Shingle Roof Repair in Florence-Graham handles the sloped portions of shallow-pitch composition roofs, typically on the street-facing sections of bungalows and duplexes. Granule loss, cracked shingles at the drip edge, and valley failures are common after years of direct South LA sun. Depending on whether we’re replacing a handful of shingles or repairing underlayment and decking, shingle repair here runs $400 – $1,800, and we always inspect the sheathing below before we quote.
Drip Edge and Valley Repair
The first place a shingled roof fails in Florence-Graham is the drip edge, where water runs off and sun beats the material hardest. We replace cracked and lifted shingles at the eave, inspect the underlayment for dry rot, and repair valleys where two shallow planes meet and channel the rare rainwater. If the decking is thin and water has gotten past, the repair gets bigger fast, which is why we inspect before we quote, not after.

Starter Strip and Ridge Work
Older homes in Florence-Graham frequently have original shingles nailed to thin 1×6 decking without a proper starter strip or ridge vent. We replace damaged sections with code-compliant details: starter strip along the eave, underlayment where the decking is exposed, and a vented ridge if the home needs one. The repair is done to current County standards, not just to match what was there in 1948.
Trusted Brands We Service in Florence-Graham
We stock products from seven manufacturers, including IKO, Atlas, and Tamko, which means we’re not trying to sell you whatever’s left in the warehouse. When we quote a repair in Florence-Graham, the material is matched to your roof’s pitch, exposure, and age. If your bungalow needs a 30-year architectural shingle to match the existing section, we can get it. If your flat roof needs a specific elastomeric from Boral, we can get that too. Fast turnaround on parts for ZIP 90001 means we’re not making you wait weeks for a repair that should take days.

AfterCommon Roof Repair Problems We See in Florence-Graham Homes
- Failed parapet flashing on shared walls. The bungalows and duplexes here often share a parapet, and when the flashing at the top of that wall fails, water tracks sideways into both units, so a leak on one side can require a coordinated repair across two properties.
- Sun-baked composition shingles. Intense UV and heat oxidize shingles on post-war homes until granules wash off and cracks form at the drip edges and valleys. The thin original sheathing sags once moisture gets past the underlayment.
- Layered patches over rotted decking. We regularly open up a roof that’s been coated or patched multiple times and find the decking underneath is soft. Past repairs often sealed the surface without removing rotted wood.
- County permit surprises. Once a repair opens the decking, LA County inspectors commonly flag undersized rafter tails, dry-rotted fascia, and missing flashing that earlier unpermitted work never addressed. That’s why we pull the permit first and price the likely scope in writing before we start.

FAQs About Roof Repair in Florence-Graham
Florence-Graham is unincorporated LA County territory, so building permits and inspections are handled by LA County rather than the City of LA. Any time a repair opens the roof decking, a permit is required, and the County inspector will check for current code compliance on the repaired section, including flashing, decking, and rafter tails. We pull the permit and coordinate the inspection as part of our repair service. Call (855) 382-1073 if you want us to handle the whole process for you.
In most cases, yes. The shared-parapet and side-by-side drainage situation in Florence-Graham often means the flashing at the property line has failed, not that either roof needs a full replacement. We assess where the water is entering, then quote a flashing repair that stops the leak at the wall-to-roof detail, whether it’s one side or a coordinated fix across both properties. Call (855) 382-1073 and we’ll take a look.
We write a repair allowance into the contract before we start, based on what we can see from the attic, from the roof surface, and from the pattern of the leak. If we open the deck and find rot beyond the allowance, we stop, show you the damage, and get your signed approval on a written change order before we proceed. Ruben Calloway built that process specifically because these old Florence-Graham homes hide damage under years of patchwork.
A flat roof repair addresses the low-slope or near-flat sections, using coatings, seam sealing, and flashing repair, while a shingle roof repair addresses the sloped portions where composition shingles are installed. On many Florence-Graham bungalows, the street-facing section is shingled and the rear addition is flat, so both types of repair often appear on the same house. We handle both under one permit and one coordinated quote.
Most Florence-Graham repairs cover one to five squares of roofing (a square is 100 square feet), and price changes by the amount of decking, underlayment, and flashing that needs replacement within that area. A small leak with no decking damage may cost as little as $350, while a repair that opens multiple squares and exposes rotted framing can run to $1,800. We’ll measure your roof and give you an exact quote before any work begins. Call (855) 382-1073 to schedule a free estimate.
