Fast, Reliable Roof Replacement Across Florence-Graham
Roof replacement in Florence-Graham runs $9,500 to $18,000 for a typical 90001 single-story bungalow, depending on tear-off layers, decking condition, and the material you pick. Flat or low-pitch fourplex roofs land a bit higher, usually $12,000 to $22,000, because of the added waterproofing and code-required slope corrections. We know these numbers because we’ve torn off enough roofs along Florence Avenue and Graham Avenue to see exactly what’s hiding under them. Call (866) 321-6172 and we’ll give you a straight, written estimate for your roof, your block, your building.
Florence-Graham is dense. The lots are narrow, driveways are shared, power lines hang low over rooflines, and most roofs sit on homes built before 1960. That changes how a replacement gets done here, and it’s why you want a crew that doesn’t have to learn it on your dime. Rick Dominguez and our Roof Replacement team handle the tight access, the hand-carried tear-offs, and the permits the way you’d expect someone who works this neighborhood regularly to handle them: without drama, without surprise bills, and without blocking your neighbor’s driveway longer than necessary.
Why Van Nuys Roofing Co Is Florence-Graham’s Preferred Roof Replacement Company
Most roofing companies in South LA treat Florence-Graham like just another stop on the map. We don’t, because this neighborhood’s housing stock comes with a specific set of problems you don’t see in West Adams or Leimert Park. The 90001 zip code is full of 1920s and 30s wood-frame bungalows with original skip sheathing, plus a solid run of postwar stucco fourplexes with flat or low-pitch roofs that pond water every time it rains. We’ve opened enough of them to know what we’re going to find before we start, and we write that into the contract.
Rick Dominguez runs our Florence-Graham replacement jobs personally, and his name goes on every quote. That matters when you’re an owner who can’t be on-site, because you’re signing a document that has to be specific enough to protect you from fifty miles away. Our customers here get photo documentation of the tear-off, written line-item pricing for decking replacement, and a call before any change order gets touched. We don’t ask you to trust the process. We show you the decking through photos and let you approve the line item in writing before we cut anything.
Response time to Florence-Graham from our Van Nuys yard is same-week for estimates, and we schedule replacements around the dumpster access and parking restrictions your block actually has. You won’t get a crew that shows up, stares at a shared driveway, and tells you the job can’t be done the way the contract says. Frankly, seven leading brands and one crew that knows them all has become our reputation in this community, and that reputation is built on the fact that we tell homeowners the truth about their roof before we sell them a replacement.

Roof Installation in Florence-Graham
Roof installation in Florence-Graham usually means full tear-off and replacement on a 1920s to 40s bungalow or a 1950s to 60s fourplex, and it’s not the same job as new construction. Existing homes carry layers of old asphalt shingles, hidden decking rot, and original framing that was never built to today’s seismic code. A typical tear-off and re-roof here runs $9,500 to $18,000 for a single-story bungalow. If we’re installing on a flat or low-pitch fourplex roof, plan for $12,000 to $22,000 once waterproofing and slope corrections are in.
We inspect first, recommend second. Before we quote installation, we get on the roof, check the decking from above, and look at the attic from below. That inspection is available as a standalone service, so if the roof isn’t actually shot, we’ll tell you that instead of selling you a job you don’t need.
Asphalt shingles on single-story bungalows
Most Florence-Graham bungalows were built with skip sheathing, meaning gaps between boards, and we usually recommend re-decking over it with solid plywood before the new shingles go down. This is the point where a cheap quote from an out-of-area roofer falls apart: the tear-off exposes soft boards, and suddenly there’s a surprise. We build decking replacement allowances into the contract up front, based on what we see during inspection and what we know about your block. Then if the tear-off matches our read, there’s no surprise. If it doesn’t, the allowance is already there and we get written approval before we spend anything.
Flat and low-pitch roofs on postwar fourplexes
The 1950s and 60s stucco fourplexes around Florence-Graham were built with flat or barely-pitched roofs, and most of them have been patched instead of properly sealed for decades. Installation on these involves the same tear-off, but we add the waterproofing these roofs were never given. Modified bitumen or TPO over new insulation, sealed penetrations, and proper slope correction so water stops ponding against the parapet. That’s why the price runs higher than a shingle roof. It’s not markup. It’s the cost of doing the roof right the first time on a building that was never designed to shed water without help.
Roof Replacement Contractor in Florence-Graham
A roof replacement contractor in Florence-Graham has to understand that this neighborhood’s homes sit shoulder-to-shoulder on small lots with limited access, and that the owner often isn’t standing in the yard watching the work. We’ve replaced roofs off Graham Avenue where the only way to get material to the roof was to carry it up a ladder from the front walk. There’s no 30-yard dumpster on the driveway, no conveyor, no room to stage. The job still gets done. We just scope it realistically from the start.
The replacement itself involves full tear-off of the old roof, decking repair or replacement where needed, new underlayment, and installation of shingles or flat roofing material. For a small bungalow in the 90001 zip, expect $9,500 to $15,000. A larger fourplex with a flat roof will run $12,000 to $22,000. If the roof has two or three layers of old shingles, add $800 to $1,500 for the extra tear-off labor and disposal, because in Florence-Graham that often means hand-bagging and carrying material out through a gate rather than throwing it down a chute into a dumpster.
Re-decking and structural work
We don’t replace a roof over rotted decking. On the older bungalows here, the original skip sheathing is often soft near the valleys and eaves, and code requires solid sheathing before the new underlayment goes down. When we find decking that needs to go, we document it with photos, price it as a line item from the allowance already in your contract, and wait for written approval. Most replacement contractors in South LA won’t show you the photo. We do. That’s the difference between a contractor who manages surprises and one who manufactures them.
Tear-off logistics on Graham Avenue lots
Power lines over the roofline are a fact of life on Graham Avenue between Florence and the 105, and that rules out a debris chute or a conveyor. Our crews tear off by hand, bag the material, and carry it down the ladder or through the side gate. If your shared driveway is the only path, we coordinate the day, keep the walkway clear, and finish the haul-out before the neighbors come home. None of this is glamorous. But it’s why our schedule on a Florence-Graham replacement holds, and why the yard isn’t covered in shingle debris at the end of the day.
Trusted Brands We Service in Florence-Graham
We work with GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, and we don’t push one over the other just because a supplier gives us a better margin. Your roof, your material choice. For most Florence-Graham replacements, GAF Timberline or CertainTeed in Florence-Graham Landmark architectural shingles make sense on the bungalows, and Boral’s tile or a GAF flat membrane works well on the fourplexes, depending on what the building can carry. Because we’re brand-agnostic, we stock and order local parts for all of them, which keeps material delays down when you’re already dealing with a tight lay-down yard on a Florence-Graham lot.

AfterCommon Roof Replacement Problems We See in Florence-Graham Homes
- Original skip sheathing that fails once exposed. The 1920s and 30s bungalows were built with spaced board sheathing, not plywood. Once we tear off the old shingles, we often find rot near the valleys and eaves, and it has to be replaced before the new roof can be installed. If it isn’t in your contract, you’re paying for it mid-job. We put it in writing up front.
- Flat roof ponding on 1950s and 60s fourplexes. Those low-slope roofs were built with minimal drainage, and decades of patching and resealing has left low spots that hold water against the parapet. Ponding water after a winter rain is the single biggest reason flat roofs in Florence-Graham fail. A proper replacement fixes the slope, not just the surface.
- Hand-carried tear-off on tight lots with power lines. Graham Avenue and the streets off it have wires running directly over the roofline and shared driveways that won’t fit a dumpster. That means the old roof comes off by hand, bagged and carried. It’s slower, and it’s why cheap quotes from contractors who don’t know the neighborhood don’t hold. Our labor pricing accounts for it from day one.
- Owner-absent approval delays on renter-occupied properties. Most roof replacements in Florence-Graham are scoped and paid for by an owner who isn’t on-site to see the condition of the decking. If the contractor can’t document findings and get written approval quickly, the job stalls with the roof half open. We run our change process by photo and written sign-off, so you’re never guessing what’s under the shingles.

FAQs About Roof Replacement in Florence-Graham
We handle them by writing decking allowances into the contract before work starts, then documenting everything with photos during the tear-off and getting your written approval before any decking work begins. A typical allowance for a Florence-Graham fourplex runs $1,500 to $4,000 depending on the roof size and condition. You approve the line item from the photos, and we only spend what you’ve signed off on. Call (866) 321-6172 for a quote that includes a realistic allowance for your building.
Because the power lines over the roofline make a conveyor unsafe and the shared driveways are too narrow for a dumpster, so the old shingles get bagged on the roof and carried out by hand. It’s slower than a conveyor job on a wide-lot property, but it’s the only way to do the tear-off without risking the wires or blocking your neighbor’s access. We price this labor into Florence-Graham estimates up front, so you’re not surprised by a change order when the crew starts tearing off.
A roofing square is 100 square feet of coverage, and most Florence-Graham bungalow roofs are between 12 and 20 squares. The shingles themselves cover the square, but your bid should list the square count because it’s how we calculate material, labor, and disposal. If one roofer quotes 12 squares and another quotes 16 for the same house, someone measured wrong, and the 12-square bid is going to come up short once the job starts. We give you the square count on every estimate in writing.
Yes, because the original flat roofs on Florence-Graham’s postwar fourplexes were built with minimal drainage and no modern waterproofing, so they pond water against the parapet and fail at the penetrations. A proper replacement includes new insulation, sealed penetrations, and slope correction, which adds to the cost but stops the leak cycle from repeating. We inspect these roofs before we quote so the price reflects what’s actually wrong, not a guess.
The shingle’s wind rating is real only if the installation matches the manufacturer’s specs: the right nail pattern, starter strip, and underlayment. We install to the manufacturer’s installation requirements for whichever brand you choose, whether that’s GAF, CertainTeed, or Owens Corning, and we don’t cut corners on the details that earn the rating. Call (866) 321-6172 for an exact quote built around the roof your building needs.
