Fast, Reliable Roof Replacement Across Sherman Oaks
Roof replacement in Sherman Oaks usually runs $14,000 to $28,000 for a typical 1,500 to 2,200 square foot home, with hillside properties south of Ventura Blvd trending toward the higher end. Most jobs take four to seven working days once permits clear. We know the 91403, 91413, 91423, and 91495 ZIP codes well, and we show up with the right materials for your specific roof, not whatever happens to be in the truck. Call Koreatown Roofing at (866) 974-2271 for a free written estimate, and we’ll walk the roof with you before quoting a single number.
Why Koreatown Roofing Is Sherman Oaks’s Preferred Roof Replacement Company
We’re a roofing-only contractor. That means every job we do in Sherman Oaks is a roof, not a side project between kitchen remodels and bathroom renovations. Our crews replace shingle roofs, tear off flat sections over additions, and rebuild decking on hillside homes along Mulholland Drive and Dixie Canyon Avenue. That focus shows up in how we handle surprises, like when we find rotten sheathing under a 1960s flat roof that looked fine from the street.
Sherman Oaks homeowners call us because we carry materials from GAF, CertainTeed, Owens Corning, and Boral, and we’ll show you the real differences in warranty terms, shingle weight, and wind ratings instead of pushing one box. Manny Cordero runs every project personally, and he’s the one who shows up for the final walkthrough. When a neighbor on Valley Vista Blvd asks who did your roof, you’ll have a name, not a call center.
We respond to Sherman Oaks estimate requests within one business day, and we schedule tear-offs around the valley heat, starting early and staging materials on the driveway, not the street where the city will ticket you. You get a written line-item bid so you can compare materials and scope against any other contractor. That’s how we build trust in the neighborhood, one roof at a time.
Styles & brands we work with






New Roof Installation in Sherman Oaks
A new roof installation in Sherman Oaks means a complete tear-off to the sheathing, inspection of the decking and framing, and installation of new underlayment, flashing, and shingles or membrane. Homeowners choose this route when a roof is past its service life, when they’re planning an addition that needs matching roofing, or when they want to upgrade to a Class A fire-rated assembly for the hillside wildfire exposure we deal with south of Ventura Blvd. Expect $15,000 to $30,000 depending on size, pitch, and material.
Mid-Century Ranch Tear-Offs
Most Sherman Oaks homes built between 1945 and 1965 were framed with 1×6 tongue-and-groove decking over rafters. That decking has spent 60 years baking in valley heat. We routinely replace sections where nails have popped and boards have cupped, before the new underlayment goes down.
Class A Assembly Upgrades
For homes in the hills off Beverly Glen or Van Nuys Blvd, LA County fire codes push for Class A roof assemblies and ember-resistant vents. We install what’s required and explain the cost difference up front, so the permit inspection passes the first time.
Reroofing in Sherman Oaks
Reroofing in Sherman Oaks, also called a recover, means installing a new shingle layer over the existing one, assuming the current roof has only one layer and the decking is sound. It’s less expensive than a full tear-off, typically $9,000 to $16,000, and it’s a reasonable option for flat-side valley homes where the decking checks out. But it’s not always the right call, and we’ll tell you when a tear-off makes more sense.
When a Recover Works
If your home north of Ventura Blvd has a single layer of shingles and no water damage underneath, a reroof saves on dump fees and labor. We check the attic and the sheathing before recommending it, because we don’t want to bury a problem under a second layer.
Why We Often Recommend Tear-Off
On older Sherman Oaks homes, especially those with additions, we often find hidden flat sections that pond water and rot the decking. A recover won’t fix that. A full tear-off lets us replace the rotted wood and add proper slope to low areas, which is the only way to stop the leak permanently.
Trusted Brands We Service in Sherman Oaks
Koreatown Roofing installs and services roofing systems from GAF, Owens Corning, and CertainTeed, along with Boral tile when the home calls for it. That matters in Sherman Oaks because a 1950s traditional on Valley Meadow Rd and a 1980s contemporary off Sepulveda Blvd need completely different materials. We keep common shingle colors and flashing components stocked locally, so a repair or replacement doesn’t stall while we order parts. Your roof, your material choice. We’ll walk you through the differences in cost, lifespan, and fire rating so you can make an informed decision based on your home and budget.

AfterCommon Roof Replacement Problems We See in Sherman Oaks Homes
- Rotten decking under flat roof sections. Sherman Oaks has hundreds of mid-century additions with original flat or low-slope roofs over rear bedrooms and garages. Water ponds there for years, and by the time we tear off, the plywood or tongue-and-groove decking is often rotted through and needs replacement before the new membrane goes down.
- Cracked flashing around skylights and chimneys. The valley sun bakes flashing every summer, and thermal expansion and contraction cracks the sealant and bends the metal. Skylights on hillside homes south of Ventura Blvd are especially prone, because they catch full afternoon sun on west-facing slopes.
- Undersized or damaged framing. We see homes where original rafters have cracked or where past additions used undersized lumber that doesn’t meet current codes. Permits require us to bring that framing up to standard, and we’ll show you exactly what we found and what the upgrade costs before we proceed.
- Curled and blistered shingles on west-facing slopes. Hillside roofs that face west or southwest get hammered by afternoon heat. Shingles curl at the edges, granule loss accelerates, and the roof fails years earlier than a north-facing slope on the same house. We see this constantly in the 91403 and 91423 hills.
Pricing for Roof Replacement in Sherman Oaks, CA
A full tear-off and replacement on a standard Sherman Oaks ranch runs $14,000 to $28,000. Architectural shingle roofs on mid-century homes with simple gable lines sit at the lower end, while complex hillside roofs with multiple planes, dormers, and skylights push toward $28,000 to $35,000. Flat or low-slope sections over additions add $2,500 to $6,000 depending on size and the condition of the decking underneath. If hidden rot shows up after tear-off, we document it, price it in writing, and get your approval before we order materials or start that repair.

FAQs About Roof Replacement in Sherman Oaks
We include a written allowance in your contract for decking replacement, typically $3 to $5 per square foot for the affected area, so hidden rot doesn’t stall the job. When tear-off reveals rotted wood, we photograph it, mark the area, and get your written approval before we replace it. On Sherman Oaks homes with flat roof additions, we expect some decking replacement and plan the schedule around it. Call (866) 974-2271 for an estimate that accounts for what we typically find in your home’s era and location.
Architectural asphalt shingles with a high solar reflectance rating hold up well in Sherman Oaks heat, and GAF Timberline HDZ and CertainTeed Landmark are the two most common choices we install. For homes in wildfire-adjacent hillside areas, Class A fire-rated assemblies with ember-resistant vents add protection. Boral concrete tile works well on heavier-framed homes and offers excellent reflectivity, but it requires structural confirmation first. We’ll show you three or four options at your estimate.
Yes, the City of Los Angeles Department of Building and Safety requires a permit for a roof replacement, including a reroof. We handle the permit application, drawings if needed, and schedule inspections. If we find undersized framing or old wiring in the attic, the permit triggers code upgrades, and we’ll price those as a written change order before any work begins.
We install modified bitumen or single-ply membrane systems on low-slope sections with proper slope correction so water drains instead of ponding. That means we may add tapered insulation or rebuild the sub-deck to direct water off the roof. On Sherman Oaks ranches with original flat additions, this is the single most important step to stop the recurring leak. We also add ice and water shield in valleys and around skylights where ponding is worst.
A properly installed architectural shingle roof lasts 25 to 35 years in Sherman Oaks, while a flat membrane section lasts 15 to 25 years depending on exposure and drainage. West-facing hillside slopes wear faster due to afternoon heat, so those sections may need attention a few years before the rest of the roof. We’ll show you how to check for early wear on the sunny side so you can plan replacement before leaks start.
