Fast, Reliable Roof Replacement Across Florence-Graham
Roof replacement in Florence-Graham means dealing with tight lot lines, flat or low-slope roofs, and homes built between the 1920s and 1950s that have been patched more times than anyone can count. We know this neighborhood’s housing stock cold. Our crews work from the roof itself on most Florence-Graham jobs because there’s no room for staging on the ground between buildings. If you’re seeing water stains on your ceiling or your tar-and-gravel roof is cracking after another hot LA Basin summer, call us at (866) 974-2271 and we’ll send someone out to look. Estimates are free, and we show up when we say we will.

How Much Does Roof Replacement Cost in Florence-Graham?
In Florence-Graham, a full roof replacement on a standard stucco bungalow runs between $9,500 and $14,000. Low-rise apartment buildings with flat roofs fall in the $15,000 to $25,000 range depending on square footage and whether the decking underneath needs to be replaced. A simple tear-off and re-roof with asphalt shingles on a 1,000-square-foot home will land near $10,500 to $12,000. Architectural shingles add about $1,200 to $1,800 to that total. If you’re pricing flat roof replacement with modified bitumen or TPO, expect $8 to $11 per square foot. Those numbers are honest, current, and based on the actual work we’ve done in the 90001 ZIP code.
What moves the number: the condition of the decking once we open the roof, whether the home needs ice and water shield at the eaves, and whether your existing roof has one layer or three. Multiple layers mean more tear-off labor and higher dump fees. If you want written line-item pricing before you sign, call (866) 974-2271 for a free estimate. We’ll walk the roof, take measurements, and put everything on paper.
Why Koreatown Roofing Is Florence-Graham’s Preferred Roof Replacement Company
We’re a neighborhood-rooted roofing contractor, not a franchised operation with rotating crews. When you call us about Roof Replacement in Florence-Graham, you’re talking to the same people who’ll be on your roof. Manny Cordero runs the shop, and his name is attached to every job we take on. That matters in a place like Florence-Graham, where houses sit so close together that your roofer’s mistakes become your neighbor’s problem within minutes.
Florence-Graham homeowners tell us the same thing over and over: they’ve had contractors quote a price, open the roof, and suddenly discover problems that double the bill. We handle it differently. Before we start, we inspect the roof, identify likely hidden issues such as rotted sheathing or outdated underlayment, and write allowances into the contract. If we find something we didn’t anticipate, we stop, show you photos, and get written approval before proceeding. No surprises, no change orders you didn’t sign off on.
We also understand what this neighborhood specifically demands. Tight lot spacing between 1920s bungalows and low-rise apartments means our crews routinely access and replace roofs without damaging adjacent properties. We sequence tear-off and installation so debris doesn’t land on a neighbor’s roof or carport. We’ve done this work on blocks near Florence Avenue, Hooper Avenue, and throughout the 90001 ZIP. We know the housing stock, the pitch issues, and the flat roofs that dominate this area.
Roof Installation in Florence-Graham
Roof Installation in Florence-Graham is rarely a clean slate. Most of the homes here were built before 1960, and the original roof framing often needs attention once the old layers come off. We install new roofs on both existing homes and the occasional new construction project in the area. For a homeowner, “roof installation” usually means full replacement: tear off everything down to the decking, repair or replace the decking, install fresh underlayment, and put down new shingles or a flat roof system. But installation also covers new construction, where we work from architectural plans and coordinate with the general contractor before sheathing goes down.
You need a new roof installed in Florence-Graham when patching no longer makes sense. If your flat roof has been silver-coated multiple times and still leaks, or your shingle roof is losing granules and shows bare asphalt, the patch route is done. A full installation on a typical bungalow here runs $9,500 to $14,000. For new construction, pricing depends on the plans and material choices; call us for a measured quote.
Decking and Underlayment
The decking is what your roofing material attaches to. In Florence-Graham homes from the 1920s through the 1950s, we often find 1×6 skip sheathing rather than solid plywood or OSB. That sheathing is frequently rotted around penetrations like plumbing vents and chimneys. We replace rotted sections with OSB or plywood before anything else goes down.
Material Selection
Your roof, your material choice. We carry architectural shingles from GAF, CertainTeed in Florence-Graham, and Owens Corning, plus flat roofing systems including TPO and modified bitumen. The right material for a Florence-Graham home depends on the roof pitch. A low-slope bungalow may not be a good candidate for shingles at all, which is why we measure pitch before making recommendations. No pressure toward any single brand.
Roof Replacement Contractor in Florence-Graham
A Roof Replacement Contractor in Florence-Graham has to handle conditions you won’t find in most of LA County. The homes are close. The roofs are flat or nearly flat. The decking is old. And the original construction often used materials that don’t meet current code. When we replace a roof here, we pull permits, schedule inspections, and make sure the finished roof passes the first time. A full replacement on a bungalow in the 90001 ZIP runs $9,500 to $14,000. Apartment buildings with flat roofs start around $15,000.
We’re a roofing-only contractor, which means 100% of our jobs are roofs. We don’t send a crew that was framing a house last week and will be pouring concrete next week. The crew that shows up in Florence-Graham does roofs every single day. That focus is why we can sequence a tear-off on a tightly packed lot without tearing up a neighbor’s stucco wall or crushing a carport.
Flat and Low-Slope Roof Systems
Florence-Graham has a huge concentration of flat and low-slope roofs covered in tar-and-gravel or rolled roofing. These systems absorb intense UV radiation all summer and crack as temperatures cycle. When we replace them, we typically install TPO, PVC, or modified bitumen over new decking and insulation. The result is a roof that reflects heat instead of absorbing it, which cuts cooling costs in a neighborhood where summer temps regularly hit the high 80s and 90s.
Tear-Off Sequencing on Tight Lots
When your roof sits inches from a neighbor’s roof or wall, tear-off can’t be a free-for-all. We work in sections, tarping adjacent walls and using controlled material handling from the roof surface itself. Debris goes into a chute or a designated drop zone, not onto the neighbor’s property. This is slow, careful work, and it’s the only way to do it right in Florence-Graham.
Trusted Brands We Service in Florence-Graham
We install products from seven manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Florence-Graham homeowners, that breadth means you choose based on what you need, not what we happen to stock. GAF Timberline HDZ is a popular architectural shingle for pitched roofs. Owens Corning Duration gives you strong wind performance, which matters during the occasional winter storm that blows through the LA Basin. CertainTeed Landmark is another solid architectural option with good color selection. We keep the common accessories in stock for these brands, so turnaround in Florence-Graham stays tight. If you want a material comparison for your specific roof, call (866) 974-2271 and we’ll walk you through it without the sales pressure.

AfterCommon Roof Replacement Problems We See in Florence-Graham Homes
Florence-Graham’s tightly packed 1920s-1950s stucco bungalows often have roofs that abut or sit within inches of neighboring structures, so tear-off and installation must be sequenced to avoid damaging adjacent properties. That’s the defining condition of roofing work here, and it’s something you rarely encounter in the hillside tile neighborhoods to the north. Here are the specific problems we run into most often:
- Multiple patched layers hiding rotted decking. We see roofs in Florence-Graham that have been silver-coated or elastomeric-coated repeatedly over failed tar-and-gravel. Those coatings trap moisture, and beneath them the decking is often rotted beyond saving. Patching over a failed system delays a full replacement but makes the eventual job more expensive.
- Skip sheathing from original construction. Homes built in the 1940s and 1950s often have 1×6 boards with gaps between them rather than solid decking. Modern shingle warranties won’t apply over skip sheathing, so we typically install new OSB or plywood before re-roofing.
- Tight lot spacing forcing roof-surface work. There is frequently no room to stage materials on the ground beside the house. We work from the roof itself, moving materials carefully and protecting adjacent walls, carports, and roofs from impact during tear-off.
- Permit-triggered code upgrades getting omitted from initial quotes. When an old roof is opened up, LA County building code often requires adding drip edge and upgrading the underlayment at the eaves. Some contractors leave these items off the first quote. We include them as allowances upfront so the contract you sign reflects the real cost.
How We Handle Hidden Issues Before They Blow Up Your Budget
Opening up an older Roof Replacement job in Florence-Graham turns up things nobody can see from the surface: rotted decking, outdated underlayment, damaged flashing, and occasionally framing that has shifted over 70 or 80 years. The biggest reason a roof replacement quote moves is that these findings get discovered mid-job and dropped on the homeowner as a surprise. We don’t work that way.
Our process starts with a full inspection before any contract is signed. We look for visible signs of trouble: sagging areas, water stains inside, cracked tar on flat sections, granules in the gutters. Then we write allowances into the contract for the things we think we’ll find: a certain number of decking sheets, a linear footage of drip edge, underlayment upgrades. If we open the roof and find more than the allowance covers, we stop. We show you photos. We write up exactly what we found and what it costs to fix, and you approve it in writing before we proceed. No one likes a moving price. Especially not on a five-figure roof.
On a 1940s stucco bungalow near Florence Avenue and Hooper Avenue, our crew tore off three layers of rolled roofing and found 1×6 skip sheathing with dry rot around the penetrations. We replaced the decking with OSB, added ice and water shield in the valleys, and installed GAF Timberline HDZ architectural shingles with a ridge vent, all without disturbing the neighbor’s carport that sits inches from the property line. That’s what replacing a roof in Florence-Graham actually looks like: old wood, hidden rot, and a tight squeeze.

FAQs About Roof Replacement in Florence-Graham
We sequence the work carefully: tear-off happens in sections, debris is managed from the roof surface itself, and adjacent walls and carports are tarped to prevent damage. If your neighbor’s structure sits inches from your property line, which is common throughout Florence-Graham, we inspect it before starting and document existing conditions. That protects both you and your neighbor. Call (866) 974-2271 if you want us to assess your specific lot and roofline for free.
When we pull a permit and open an older roof, LA County code often requires adding drip edge at the eaves and upgrading the underlayment, especially in areas prone to wind-driven rain. Homes with skip sheathing will need solid decking installed before new shingles go on. Some contractors omit these items from their initial quotes; we write them in as allowances upfront so you’re not surprised. The total effect on a Florence-Graham bungalow is typically $1,000 to $2,500, depending on roof size.
Yes, but it’s a structural change, not just a roofing job. Converting a flat roof to a pitched roof in Florence-Graham requires engineering, new framing, and a permit. The total cost usually runs $18,000 to $30,000 or more, depending on the roof’s square footage and the pitch you want. For most homeowners, replacing the flat roof with a modern TPO or modified bitumen system is the more cost-effective choice at $8 to $11 per square foot. We’ll show you both numbers so you can decide.
Most stucco bungalows in Florence-Graham have roofs between 10 and 16 squares, where one square equals 100 square feet. A 1,000-square-foot roof is 10 squares. Contractors quote by the square, so if one quote assumes 10 squares and another assumes 13, the prices won’t compare. When we give you a free estimate, we measure the roof and write the square count on the quote. Call (866) 974-2271 to get that measurement.
Yes. Owens Corning Duration and GAF Timberline HDZ both carry strong wind ratings, and we install them in Florence-Graham regularly. The flat roofs here face more UV damage than wind damage, but when winter storms push through the LA Basin, wind-rated shingles give you a margin of safety that entry-level three-tab shingles don’t. We’ll show you the wind-rating differences and what they cost before you choose. Estimates are free at (866) 974-2271.
