Fast, Reliable Roof Repair Across Compton
Roof repair in Compton usually runs between $350 and $1,800 depending on what we find once we open things up. Most repairs on the city’s older tract homes take one day, and we schedule Compton jobs every week. If you’ve got a ceiling stain, missing shingles, or a flat roof that’s been recoated too many times, call Koreatown Roofing at (866) 974-2271 for a straight answer and a free estimate. We work on Compton roofs because we understand what decades of sun and patch jobs do to them.
Key takeaways:
- Compton’s 1940s – 1960s tract homes overwhelmingly have low-slope or flat roofs, not steep shingle roofs.
- Repeated coatings on original tar-and-gravel roofs often trap moisture underneath, causing hidden rot.
- We carry materials for both flat-roof patching and shingle repair, so we don’t have to order and delay.
- Every estimate is free, written, and line-itemed before work begins.
Why Koreatown Roofing Is Compton’s Preferred Roof Repair Company
We’re a roofing-only operation. That matters in Compton because the city’s housing stock has a very specific failure pattern: aging low-slope roofs with multiple coating layers that hide problems from the surface. A general contractor who does roofing on the side won’t recognize a moisture-trapped elastomeric coating blistering over rotted decking. Our crews see it weekly in ZIP codes 90222, 90223, and 90224.
The Roof Repair work we do across Compton includes Shingle Replacement, Flashing Repair, Flat Roof Patch, and Vent Boot Repair. We don’t sub out the job to a rotating crew. Manny Cordero runs our team, and he’s the one you’ll talk to when you call about a problem. No call center, no franchise script. When a Compton homeowner tells us the roof was recoated twice and still leaks, we know exactly where to look.
Styles & brands we work with
Commercial Roof Repair in Compton
Commercial Roof Repair in Compton typically means working on flat or very low-slope built-up roofs over warehouses, retail bays, and older office buildings along corridors like Alameda Street, Rosecrans Avenue, and Artesia Boulevard. These systems fail differently than residential shingles. We look for open seams, ponding water, failed drain collars, and delamination between coating layers. A typical commercial flat-roof patch in Compton runs $600 – $2,400 depending on the membrane type and how far the moisture has spread.
Coating Systems and Membrane Patching
Many Compton commercial buildings have either BUR (tar-and-gravel) or modified bitumen roofs that have been coated with reflective aluminum or elastomeric. When those coatings crack or bubble, we cut back to sound material, repair the membrane underneath, and re-coat only if the substrate is dry. Coating over damp felt just repeats the failure cycle.
Older buildings near Compton Boulevard often have rooftop equipment that was never properly flashed. We repair the flashing and re-seal penetrations so the next rain doesn’t find the same path inside.
Roof Leak Repair in Compton
Roof Leak Repair in Compton most often starts with a stain on a ceiling or a drip at a wall junction after winter rain. Three out of four times on the city’s older homes, the leak isn’t where the stain is. Water travels along roof framing and shows up feet away from the actual entry point. We trace the path before we patch anything. A basic leak repair runs $350 – $900, but if the decking under the roof membrane is rotted, expect $1,200 – $1,800 for the full repair scope.
Flashing, Pipe Collars, and Valleys
Rusted flashing at chimneys, plumbing vent pipes, and wall transitions is the leading cause of leaks on Compton’s 70-year-old roofs. We replace the flashing, not just caulk over it. Caulk is a temporary stop gap that fails the next time the roof expands in summer heat.
Valley repairs on the city’s handful of pitched shingle roofs are another common job. When old shingles delaminate at a valley, water gets under the protective layer and rots the sheathing. We strip, inspect, and replace before refelting and shingling.
Trusted Brands We Service in Compton
Koreatown Roofing installs and repairs materials from seven manufacturers, so the right product for a Compton roof is genuinely the right product, not whatever one brand we happen to be loyal to. For shingle repairs and replacements, we regularly handle GAF repair in Compton, plus work with Owens Corning and CertainTeed. For flat-roof and commercial systems, we work with IKO and others. We keep common flashings, vent boots, and coating materials stocked for Compton jobs, which means fewer trips back to the supply yard and a faster turnaround for you. The brands we service are the ones already on most Compton roofs, so matching materials and finishes is straightforward.

AfterCommon Roof Repair Problems We See in Compton Homes
- Moisture trapped under multiple coatings. Original 1950s tar-and-gravel roofs north of Compton Boulevard have often been recoated with aluminum or elastomeric products three or more times. Each coat seals the surface, but traps moisture that rusted flashing and rotted decking.
- Sun-baked shingles on pitched sections. The 1940s – 1960s tract homes with sloped roofs typically have old asphalt shingles that are brittle and cracked after 70 summers of intense UV exposure. Repairing them requires careful handling so adjacent shingles don’t disintegrate.
- Seam failures on built-up roofs. BUR roofs fail at seams and laps first. Compton’s hot, dry summers expand the material; winter rains shrink it. That cycle eventually opens gaps where water gets in, especially near roof drains and scuppers.
- Failed flashing around mechanical penetrations. Older Compton homes got air conditioning units and swamp coolers added decades after the roof was installed. The flashing around those later penetrations was frequently done with sheet metal and tar that eventually fails, letting water run down inside walls.
Pricing for Roof Repair in Compton, CA
For a straight answer: expect $350 – $900 for a typical leak repair on a Compton home, $600 – $1,600 for flashing and valley work, and $800 – $2,400 for a flat-roof patch that includes cutting out wet sections and re-roofing. When hidden rot or failed decking is involved, the full repair scope usually lands between $1,200 and $3,500 depending on how many sheets of plywood or OSB the structure needs. The deciding factor is almost always whether the roof has been recoated repeatedly without addressing what’s underneath.

FAQs About Roof Repair in Compton
The coating is sealing moisture inside instead of keeping it out. Many Compton flat roofs, especially north of Compton Boulevard, were built as tar-and-gravel systems in the 1950s. When they got recoated with aluminum or elastomeric sealants to extend their life, any water already trapped in the old layers had no way to escape. The result is blistering, hidden rot, and leaks that reappear within months. The fix is to cut back to dry material, replace the rotted decking, and only then re-coat with a breathable reflective system. Call (866) 974-2271 for an exact assessment; estimates are free.
Most emergency leak repairs and patches don’t require a permit, but any structural repair that involves replacing roof decking or changing the roof system typically does. Compton’s building department requires permits and inspections on work that alters the roof structure. We handle permit paperwork for any repair that triggers the requirement, and we make sure the inspection passes before we call the job done. If you’re unsure whether your job needs a permit, we’ll tell you honestly up front.
A repair fixes a specific failed area: flashing, seams, a vent boot, or a limited section of rotted decking. A re-roof removes the entire existing roof system down to the structure and installs a new one. For many 1950s Compton homes with original BUR or tar-and-gravel roofs that have been coated multiple times, the point where repeated repairs no longer make sense arrives sooner than homeowners expect. If we open a section and find widespread moisture between layers, we’ll tell you honestly whether continued patching will just keep failing.
We stop, document what we found with photos, and bring you a written cost for the additional scope before we touch it. No surprise bills after the fact. Manny Cordero personally reviews every change-order request. If we find the decking is rotted under a patch we’re about to apply, we’ll explain what the repair requires, what it adds to the cost, and you decide. We never proceed on a verbal “should be fine.”
Yes. We handle flat and low-slope commercial roofs across Compton, including buildings along Alameda Street, Rosecrans Avenue, and in the industrial districts around the 91 and 710 freeways.
