Fast, Reliable Roof Repair Across Los Angeles
Roof repair in Los Angeles usually runs $350 – $1,400 for the common fixes we handle, and the job centers on one truth: LA’s dry season quietly damages your roof months before the first winter rain reveals the leak. We’re Koreatown Roofing, and we work exclusively on roofs across Los Angeles, from the 1920s bungalows off West Adams Boulevard to the flat built-up roofs on pre-war apartment buildings near USC. If you’ve spotted a ceiling stain in Echo Park or water streaking down an interior wall in Silver Lake, call us at (866) 974-2271. We’ll schedule a free estimate and explain exactly what’s failing and what it costs before any work begins.
Why Koreatown Roofing Is Los Angeles’s Preferred Roof Repair Company
We’re roofers, not general contractors who dabble in roofing between kitchen remodels. Every job we take in Los Angeles is a roofing job: inspection, repair, or replacement. That focus means our crews know what a sun-baked flashing seam looks like on a 1920s low-pitch roof in ZIP 90037, and they know the box-gutter failure points on pre-war apartment buildings in 90036. Our reputation lives in the neighborhoods we serve. When a homeowner near MacArthur Park calls us back for a second repair three years after the first, that’s the accountability we want. We don’t rotate random crews through a call center. The people who show up in Los Angeles are our people, and they answer for the work.
We carry materials from seven manufacturers, including GAF, CertainTeed, and Owens Corning, so a repair doesn’t force you into whatever one brand happens to have on the truck. Manny Cordero, who leads our team, has built the company around a simple idea: you should get the material that fits your roof and your budget, not the material that fits our supplier agreement. That’s why we stock a wide fastener and sealant selection locally, so we’re not waiting on a distributor when your valley is lifting after the first November storm.
Key takeaways:
- Roof repair in Los Angeles typically costs $350 – $1,400 depending on the failure.
- We’re a roofing-only contractor. Repair, inspection, replacement. Nothing else.
- We work with seven manufacturers, so your repair uses what fits, not what’s convenient for us.

Styles & brands we work with
Roof Leak Repair in Los Angeles
Roof Leak Repair in Los Angeles is the single most common call we get after the first heavy rain in November, and in most cases the leak was set up months earlier by the long dry season. Sealant at flashing and box-gutter seams bakes under eight months of sun, develops hairline cracks, and then opens up the moment real water hits. A straightforward leak repair, where we locate the entry point and reseal or refasten the failing section, typically runs $350 – $750 in Los Angeles. If the leak has been running for weeks and the decking under the shingles is rotted, the repair pushes toward $900 – $1,400 once we cut out the damaged section and rebuild it.
Finding the failure before it finds your ceiling
We start every leak call by walking the roof surface and the attic if there’s access. Water can travel several feet from the actual entry point before it drips through your ceiling, so a stain in the living room doesn’t mean the leak is directly above it. On low-pitch Los Angeles bungalows, the valley intersections and pipe penetrations are the usual suspects.
The right sealant and fastener, not a smear of caulk
A tube of hardware-store caulk on a sun-baked flashing joint might last one season. We remove the old sealant, clean the metal, and reseal with a product rated for LA’s UV load. When fasteners have rusted and backed out, we replace them with hot-dip galvanized or stainless hardware that holds through another decade of dry-wet cycles.
Emergency Roof Repair in Los Angeles
Emergency Roof Repair in Los Angeles is what you need when a winter storm has already opened a hole and water is coming into the house now, not next week. The call pattern is predictable: the first atmospheric-river storm of the season hits South LA, and within hours we’re tarping flat built-up roofs and securing lifted shingles. Emergency tarping and temporary sealing usually runs $400 – $800 for the immediate response, with the permanent repair priced separately after the weather clears and we can see the full scope. Call (866) 974-2271 and we’ll walk through what’s happening and get someone out to you.
What an emergency tarp does and doesn’t do
A proper tarp job stops active water entry and buys you time for the permanent fix. It’s not a repair, and any roofer who says otherwise is selling you false confidence. We anchor the tarp under the ridge or behind the drip edge where possible, not just over the hole, because LA’s winter wind will rip a poorly anchored tarp off within a day.
Why the first storm hits LA hardest
Months of dry heat create the damage, but the first heavy rain is when it declares itself. Sun-embrittled sealant opens, rusted-through nails release, and flat-roof seams split. That’s why our November and December schedule fills fast. If you see water now, don’t wait for the stain to spread: wet decking rots, and a $500 patch becomes a $1,400 decking replacement within weeks.
Trusted Brands We Service in Los Angeles
Your roof, your material choice. We repair and replace roofs using products from seven major manufacturers, including GAF, CertainTeed, Owens Corning, and Boral. That range matters in Los Angeles, where the right material for a 1920s composition-shingle bungalow in 90038 isn’t necessarily the right material for a flat built-up apartment roof in Hollywood. We stock local parts for fast turnaround across Los Angeles, so when your repair calls for a CertainTeed valley accessory or a specific GAF sealant, we’re not waiting on a distributor to ship from out of state. One contractor, every stage: the repair we do today carries the same material accountability as the replacement we might do in ten years.
Common Roof Repair Problems We See in Los Angeles Homes
- Sun-baked sealant at flashing and box-gutter seams: Los Angeles’s dry season runs eight or nine months, and that heat embrittles the sealant around chimneys, vents, and parapet walls. The cracks form quietly all summer, then leak the moment the first winter rain arrives, which is why November call volume spikes so hard.
- Rusted or backed-out fasteners on 1920s low-pitch roofs: The original nails in many older Los Angeles roofs have been corroding for decades. On low-pitch bungalows, those failing fasteners let shingles lift at valleys and penetrations while the shingle itself still looks serviceable.
- Flat built-up roofs failing at box-gutter seams near USC: Pre-war apartment buildings in central LA share a failure pattern: the built-up roof membrane cracks at the box-gutter seams year after year. Patch jobs that skip the underlayment and seam detail underneath fail again within a season.
- Shallow gutters on 1920s bungalows: Many of the older homes across 90036 and 90037 have gutters that were sized for a different era. In winter rain, they overflow at the corners and run water down the fascia and into the walls, which reads as a roof leak but is often a drainage problem we fix as part of the repair.

AfterPricing for Roof Repair in Los Angeles, CA
A typical roof leak repair in Los Angeles runs $350 – $750. Emergency tarping and temporary sealing runs $400 – $800. A more involved repair with rotted decking replacement runs $900 – $1,400. What moves the number: whether the decking under the shingles is still sound, whether we’re working on a steep pitch or a flat built-up roof, and whether the fasteners need full replacement rather than spot treatment. The dry-season damage ties directly into cost: if we catch the backed-out nails before the decking rots, you’re at the low end. If the leak ran for weeks, you’re at the high end.

FAQs About Roof Repair in Los Angeles
Los Angeles’s long dry season bakes and embrittles roofing fasteners and sealants for eight or nine months, so the failures that appear during the first winter rain were quietly set up all summer, not caused by the storm itself. The first heavy rain exposes every cracked flashing joint, rusted nail, and split box-gutter seam at once. If you want the repair done before the next storm cycle, call (866) 974-2271 for a free estimate.
For Los Angeles’s dry-wet cycle, we specify hot-dip galvanized or stainless fasteners rather than cheap electroplated nails. The electroplated coating fails within a few years under LA sun and winter rain, the nail rusts, and the shingle lifts. For most of our Los Angeles repairs, hot-dip galvanized is the right balance of cost and longevity. Call (866) 974-2271 and we’ll tell you what your specific roof needs.
The fasteners and valley flashing fail first. On a 1920s Los Angeles low-pitch roof, the original nails corrode and back out of the decking, which lets the composition shingles lift at the valleys and penetrations even when the shingle itself has years left. Shallow gutters compound the problem by overflowing at the corners during winter storms. We inspect both the roof surface and the drainage when we quote a repair.
Compare the fastener and sealant spec, not just the price. A $400 bid that uses electroplated nails and hardware-store caulk will fail again within a few Los Angeles dry-wet cycles. A $700 bid that specifies hot-dip galvanized fasteners and UV-rated sealant is cheaper over ten years. Ask each roofer what fastener and sealant they’ll use, and call (866) 974-2271 if you want us to walk through the options.
Yes, we repair flat built-up roofs on pre-war apartment buildings throughout the USC area and across Los Angeles. Our crews focus on the box-gutter seams, where these roofs fail year after year. The repair that lasts is the one that replaces the failed underlayment and seam detail underneath, not just a top-layer patch. For a free estimate on your building, call (866) 974-2271.
