Fast, Reliable Roof Replacement Across Florence-Graham
Roof replacement in Florence-Graham usually costs between $9,500 and $18,000 for a typical post-war stucco home, and the work generally takes four to seven days once materials arrive. The price is driven by what’s under the old roof more than what goes on top of it. If you’re off Florence Avenue or over near Compton Avenue, you already know the drill: small lots, shared walls, old built-up roofs, and permits that run through LA County, not the City. We know those streets, we know those roofs, and we know what the County inspector is going to ask for before we ever tear anything off. Call (833) 589-5180 to schedule a free roof inspection and get a written, line-item replacement estimate.
Answer-First: What Roof Replacement in Florence-Graham Actually Costs
A full tear-off and reroof on a small Florence-Graham bungalow typically runs $9,500 to $14,000 for architectural asphalt shingles. A flat or low-slope built-up roof replacement on the same house runs $11,000 to $18,000, depending on membrane type and decking condition. If hidden dry-rot or undersized sheathing shows up after tear-off, add $1,500 to $4,000 for decking replacement, which is common in homes built between 1920 and 1955. Those numbers are not guesses. They’re based on the housing stock, lot access, and LA County code requirements unique to ZIP 90001. Call (833) 589-5180 for an exact quote. Estimates are free.

Why Sunridge Roof Repair Is Florence-Graham’s Preferred Roof Replacement Company
Most Florence-Graham roofs fail in one of three ways: rotted flashings from UV-baked thermal cycling, cracked seams on low-slope built-up roofs, or leaky tie-ins where a backyard addition meets the original house. We’ve worked on all three, repeatedly, across this specific ZIP code. That repetition matters because every roof here has the same DNA: small footprint, old framing, shared property lines, and County permitting. A roofer who only does steep-pitch shingle work in the suburbs will misjudge what a Florence-Graham roof needs. We won’t, because roofing in 90001 is what we do every week.
Ruben Ochoa, our owner, has walked hundreds of roofs in unincorporated LA County. He’s the one who makes the final call on repair-versus-replace. That’s the advantage of working with a roofing-only company: the person quoting your job is a roof specialist, not a general contractor sending a roofing sub out for the day. You get an honest read, a written scope, and a price that holds. Roof Replacement is one of three services we offer, and inspection is always the first step. We’d rather tell you the roof has five years left than sell you a new one you don’t need.
Reroofing in Florence-Graham
Reroofing in Florence-Graham is rarely a cosmetic upgrade. In this neighborhood, reroofing means recovering a structure that was built between the 1920s and 1950s, often added onto over the decades, and exposed to hard UV for seventy-plus summers. The job usually involves a full tear-off down to the decking, replacement of any rotted or undersized sheathing, new underlayment, and a complete shingle or membrane system. Most Florence-Graham reroofs fall between $9,500 and $16,000, depending on roof size, slope, and what the tear-off uncovers. That price includes LA County permit fees and the two required inspections.
Tear-Off vs. Overlay
We do not recommend overlaying new roofing over old in Florence-Graham. The original roofs here are often low-slope built-up or early shingle systems, and layering hides the very failures that will leak next winter. A full tear-off costs more upfront, but it reveals dry-rot and lets the County inspector actually verify the decking. That matters for resale too, especially in a market where many homes carry non-permitted additions.
Sheathing Allowances in the Contract
Every Florence-Graham reroof quote we write includes a line-item allowance for decking replacement. If we find rotted or skip-sheathed decking after tear-off, the cost is already stated in your contract, not sprung on you as a change order. You approve the number before we start. Nothing gets added without your written sign-off.
Flat Roof Replacement in Florence-Graham
Flat roof replacement in Florence-Graham means working on the most common roof type in the neighborhood, but also the most misunderstood. These low-slope built-up roofs don’t shed water like a pitched shingle roof. Water pools, slowly, and works its way into seams, penetrations, and flashings until the membrane fails. Replacement typically costs between $11,000 and $18,000 for a post-war bungalow, with the final number driven by the membrane you choose (modified bitumen, TPO, or PVC), the amount of decking that needs replacing, and the number of penetrations: plumbing vents, swamp cooler legs, wall tie-ins, and old antenna mounts. LA County code also requires specific underlayment details on flat roof replacements in 90001.
Built-Up Roof Tear-Offs
On a 1948 stucco bungalow off Florence Avenue, our crew pulled off three layers of aging built-up roofing and found the original 1×6 skip sheathing was dry-rotted and undersized for a modern architectural shingle system. We wrote a sheathing-replacement allowance into the contract before the tear-off, priced the new 7/16 OSB and ice and water shield in the valleys and penetrations, and got written approval from the homeowner before laying a single square. The County inspector signed off on the upgraded decking and drip edge, and we finished with a ridge vent and new fascia to close out the tie-in to the neighbor’s wall. That’s a typical Florence-Graham flat roof job. It’s never just the membrane.
Membrane Selection for Low-Slope Roofs
For Florence-Graham’s low-slope roofs, we recommend modified bitumen for budget-conscious replacements and TPO or PVC when the homeowner wants reflectivity and longer service life. The UV load here is intense, and a dark built-up roof absorbs heat that accelerates membrane cracking. A white TPO roof can drop surface temperatures enough to extend the membrane’s life by a decade, and that’s not a sales line. It’s physics, and it’s why we show customers the material data before they choose.
Trusted Brands We Service in Florence-Graham
We install and repair roofing products from seven manufacturers, so the brand recommendation you get from us is driven by your roof’s condition and your budget, not a supplier agreement. That means we can pair a premium GAF, CertainTeed, or Owens Corning system with a Florence-Graham homeowner who wants the long-term warranty and curb appeal, and we can also quote IKO, Atlas, or Tamko when the goal is a solid reroof without premium pricing. Budget flexibility matters here. We stock common flashing, underlayment, and venting materials used in 90001, which keeps most replacement jobs moving without waiting on specialty orders. For Florence-Graham homeowners, that means a faster turnaround and a clear, honest material recommendation.

AfterCommon Roof Replacement Problems We See in Florence-Graham Homes
- Dry-rot at flashings and flat-roof seams. Florence-Graham’s hot, dry summers and near-zero snow mean roofs here fail from UV degradation and thermal expansion, not ice. The damage hides for years, then winter rain finds every crack.
- Non-permitted additions with bad tie-ins. Backyard additions and converted garages are everywhere in 90001, and their roof connections to the original structure are where water gets in. Underlayment and ice and water shield were rarely integrated properly on these add-ons.
- Skip-sheathing that cannot support modern shingles. Original 1×6 skip sheathing was fine for 1940s three-tab shingles, but it fails under architectural shingles. We replace it with 7/16 OSB before installation, and we price that replacement in advance.
- Pooling water against shared property lines. Low-slope roofs on zero-lot-line homes drain toward the neighbor’s wall. When the membrane cracks at that seam, water follows the shared wall down into both structures. LA County code requires specific flashing details at those tie-ins, and we build them to spec.
Pricing for Roof Replacement in Florence-Graham, CA

FAQs About Roof Replacement in Florence-Graham
Yes. Florence-Graham is unincorporated LA County in ZIP 90001, so every roof replacement permit runs through LA County Building & Safety, not the City of LA. That means two inspections: one after tear-off to approve the decking, and one final. A contractor quoting City of LA rules will miss required sheathing upgrades and permit triggers that the County inspector will catch. We pull the permit, schedule both inspections, and close out the project with full County sign-off. Call (833) 589-5180 to ask about your specific roof.
We replace it, and the cost is already in your contract. Every Florence-Graham quote we write includes a decking replacement allowance, typically $1,500 to $4,000, because rotted or undersized sheathing is common in homes from the 1920s through the 1950s. If we find rot after tear-off, we show you photos, confirm the allowance covers it, and get your written approval before installing new 7/16 OSB. No surprise change orders.
Yes, the house stays intact. We tear off only the roofing material and damaged decking, not the structure. The work happens from above, and we protect the interior with tarps and daily cleanup. Most flat roof replacements on Florence-Graham bungalows take four to six working days, weather permitting. Your family stays in the house during the job.
We treat shared-wall tie-ins as a critical flashing detail, not an afterthought. On zero-lot-line Florence-Graham homes, the roof meets the neighbor’s wall along a common property line, and that seam is where leaks start. We install proper step flashing, counter-flashing, and sealant details that meet LA County code, and we document the condition of the shared wall before and after. If the neighbor’s wall has damage from years of leakage, we photograph it and discuss how the new flashing stops the water.
Sometimes, and we’ll tell you exactly what applies to your house before you sign. If your home has a non-permitted backyard addition with an improper roof tie-in, the County inspector may require that tie-in to be corrected as part of the permit. That can add cost, but ignoring it leaves a leak that reappears every winter. We identify these issues during inspection, price them in writing, and never surprise you with a County requirement after the job starts. Call (833) 589-5180 for a free inspection and a straight answer on what your roof needs.
