Fast, Reliable Roof Replacement Across Koreatown
A full roof replacement on a Koreatown building typically costs $9,800 – $24,000 depending on whether we’re tearing off a flat built-up membrane on a 1920s apartment block or re-shingling a postwar stucco bungalow. We run crews through Koreatown every week and know the buildings along Olympic, Western and Vermont well enough to quote accurately before we pull a single shingle. If you’re weighing repair against replacement on an older property in 90005, call (866) 321-6172 and we’ll inspect first and give you straight numbers.
What makes Koreatown different from the rest of Los Angeles is the roof stock itself. This is dense, pre-1970 housing: Spanish Colonial and Craftsman bungalows with original wood-framed flat roofs, low-rise apartment buildings with parapets and rooftop HVAC, and mixed-use commercial strips where a restaurant’s kitchen vent sits ten feet from a tenant’s skylight. A roofer who only does single-family shingle work will miss what these buildings actually need. We won’t.
Why Van Nuys Roofing Co Is Koreatown’s Preferred Roof Replacement Company
Koreatown owners call us because we don’t steer every job toward the same material. We work across seven major manufacturers’s product lines, including Tamko, Boral, GAF and CertainTeed. That means a landlord with a low-slope apartment roof gets a membrane recommendation based on ponding and parapet flashings, not on whatever brand happens to be sitting in our yard. A homeowner on a Craftsman bungalow gets architectural shingles rated for the Santa Ana wind events that peel cheap three-tab off the Olympic corridor every fall.
Our inspection-first approach matters here more than anywhere. Koreatown’s buildings hide problems under old roofing that a quick walk-around won’t catch. We inspect and document before we quote, so you’re not signing a contract that doubles in price when the tear-off exposes rotted decking. Rick Dominguez runs our crews to that standard on every job, and it’s why owners from Koreatown keep our number after the warranty paperwork is filed. We’re reachable fast when a winter storm opens a leak at a parapet flashing or clogged drain.
No reviews or star counts to flash here. What we can say is that our repeat work in Koreatown comes from landlords managing multiple 90005 buildings and homeowners who wanted an honest condition report before committing to a spend. That’s the reputation that matters.
Styles & brands we work with






Roof Replacement Contractor in Koreatown
A Roof Replacement Contractor in Koreatown has to handle two very different jobs on the same block. The first is a full tear-off and re-cover of flat and low-slope membranes on multi-family and mixed-use buildings. The second is a conventional shingle re-roof on the bungalows and stucco homes that still make up the residential side streets off Western. A complete replacement in 90005 runs $9,800 – $24,000, with flat commercial-style work at the higher end once we factor parapet flashing, drain replacement and rooftop equipment re-flashing.
Code-Triggered Repairs When the Roof Opens Up
Here’s what actually moves a Koreatown replacement quote. On older buildings, the permit requires us to bring deficient framing and waterproofing up to current code once the roof is opened. That means soft decking gets replaced, undersized rafters get repaired or sistered, and the roof can’t close until the inspector signs off. We write allowances into the contract for exactly this, and every change order is priced and approved by you in writing before our crew touches it.
Re-Flashing Parapets, Drains and Rooftop Equipment
Koreatown’s flat roofs carry signage, HVAC units, kitchen vents, and sometimes a congregation of satellite dishes. Each penetration is a leak waiting for the first winter storm. Our replacement work includes re-flashing every penetration and clearing or replacing drains so ponding water stops sitting against flashing. That’s the difference between a roof that lasts 15 years and one that leaks again in two.
Asphalt Shingle Roof Replacement in Koreatown
Asphalt Shingle Roof Replacement in Koreatown applies mostly to the single-family bungalows and postwar homes in 90005, where architectural shingles hold up better than three-tab against the wind that funnels down Olympic and Western. A full tear-off and re-shingle on a typical Koreatown home runs $9,800 – $16,500, including new underlayment, starter strip, and ice and water shield in valleys. Homes with steep pitches, multiple dormers or original skip sheathing that needs replacement will land higher.
Architectural Shingles Rated for Santa Ana Winds
We install architectural shingles from CertainTeed, GAF, Tamko and others with high wind ratings, and we follow each manufacturer’s nailing pattern and starter-strip requirements instead of cutting corners on fasteners. The failures we see after Santa Ana events are almost always improper nailing or missing edge detailing. Proper installation math fixes that.
When the Decking Underneath Has Failed
On a 1920s Spanish Colonial bungalow off Western, our crew tore off a wind-lifted modified-bitumen membrane only to find soft decking and an undersized fascia where winds had been working the drip edge loose. We documented the damage, priced the decking replacement and framing repairs in writing, and got owner approval before laying new underlayment and shingles. That’s not a scare story, it’s a typical day in Koreatown.
Trusted Brands We Service in Koreatown
We’re fluent in seven roofing material lines, and that matters when a Koreatown owner wants to compare warranty terms between GAF and CertainTeed without being pushed toward whichever brand earns the roofer the biggest rebate. Our crews know the installation specs, fastener schedules and warranty-eligibility requirements for Tamko, Boral, GAF and CertainTeed product lines, among others. Material-neutral means your roof’s condition and your budget drive the recommendation. We stock common components locally and can turn around most Koreatown replacements without waiting on slow special orders.

AfterCommon Roof Replacement Problems We See in Koreatown Homes
- Rotted decking under old flat roofs. Original wood-framed flat roofs on 1920s and 1930s bungalows hide soft spots that a visual inspection misses. Once the membrane is opened, the permit requires the framing to come up to code before we close the roof.
- Parapet and rooftop HVAC flashing failures. Older apartment buildings along Wilshire and Olympic trap water at parapet walls and equipment curbs. Failed flashing and clogged drains cause winter ponding leaks long before a shingle roof would show wear.
- Santa Ana wind lift on low-slope and shingle edges. Gusts funnel down the Olympic and Western corridors and peel loose membrane edges, tile edges and improperly nailed shingles. Missing starter strip and drip edge detailing are the usual culprits.
- Ponding on low-slope built-up roofs. Koreatown’s short winter rainy season concentrates water on roofs with settled low spots. Once ponding starts, the membrane degrades faster and drain clogs turn small leaks into ceiling damage below.
Pricing for Roof Replacement in Koreatown, CA
Use these ranges as a starting point for 90005 work. A single-family shingle re-roof runs $9,800 – $16,500. A flat or low-slope replacement on a small apartment building or mixed-use property runs $14,000 – $24,000 once parapet re-flashing, drain work and rooftop equipment sealing are included. Full new construction starts around $18,000 and goes up with framing complexity. What moves the number in Koreatown is what the tear-off exposes: old decking, framing upgrades a permit triggers, and how many penetrations need re-flashing. We write those allowances into the contract and price any change order in writing before work continues. Call (866) 321-6172 for a free estimate with real line items.

FAQs About Roof Replacement in Koreatown
Because once the old membrane or shingles come off, the permit requires deficient framing, rotted decking and failed waterproofing to be brought up to code before the roof can close. On 1920s and 1930s bungalows in 90005, that means undersized rafters, soft sheathing and bad valley flashing surface regularly. We handle it by writing code-upgrade allowances into the contract up front and pricing every surprise in writing before we touch it. Call (866) 321-6172 for a quote that accounts for what Koreatown buildings actually hide.
We tear off the old built-up or modified-bitumen membrane down to the deck, inspect and repair framing as the permit requires, then re-cover with a membrane suited to the building’s slope and exposure. Every parapet wall, HVAC curb, vent pipe and drain gets re-flashed or replaced. On a low-rise block we recently handled, we replaced ponding sections and added new drains so winter storms would stop backing water up at the flashings. The job is really a tear-off-and-rebuild around equipment, not a simple re-cover. Call (866) 321-6172 to schedule an inspection.
Yes, we install high-wind-rated architectural shingles from manufacturers like CertainTeed, GAF and Tamko on Koreatown’s single-family homes, and we follow each brand’s nailing pattern and starter-strip requirements exactly. The wind failures we see after Santa Ana events are almost always missing starter strip, improper nailing or no drip edge. Correct installation is what makes the wind rating mean something. Call (866) 321-6172 for a free estimate on an architectural shingle replacement.
On Koreatown’s older flat-roof buildings, the decking usually needs at least partial replacement once the old membrane is off. Soft or rotted sections get cut out and replaced, and if the framing underneath is undersized or damaged, the permit requires us to repair or sister it before the new roof closes. We document everything with photos and get written approval before adding any work. Call (866) 321-6172 and we’ll walk you through what your roof’s decking likely needs.
Line-item both bids and compare three things: whether each includes decking replacement allowances and code-upgrade language, whether parapet flashings and rooftop penetrations are explicitly priced, and what membrane or shingle brand and warranty is specified. A bid that ignores the building’s parapets and HVAC curbs is leaving money off the front end to win the job. We quote Koreatown work with those line items written in from the start. Call (866) 321-6172 for a detailed written estimate.
