Fast, Reliable Roof Replacement Across Manhattan Beach
Roof replacement in Manhattan Beach typically costs between $14,000 and $32,000 for a full tear-off and re-roof on an average 1,800-square-foot home, with flat roof work running $12,000 to $24,000 depending on decking condition and access. We serve every Manhattan Beach neighborhood from the sand section to the tree section, and we know what salt air and tight lots do to a roof over time. If you’re weighing a repair against a full replacement, call Manny Cordero at Koreatown Roofing at (866) 974-2271 for a straight answer and a free written estimate. We do roofing only, and we’ve done enough Manhattan Beach jobs to tell you what your roof actually needs before we touch it.
Why Koreatown Roofing Is Manhattan Beach’s Preferred Roof Replacement Company
Manhattan Beach homeowners call us because we aren’t a general contractor squeezing roofing between kitchen remodels. We are roofing specialists. Every inspection, repair, and Roof Replacement our crew handles is roofing work, period. That focus matters on a coastal lot where corrosion hides under old flashing and decking issues only show after tear-off.
We’ve worked throughout Manhattan Beach long enough to know the difference between a Hill Section home on a steep slope and a sand section bungalow on a tight flat lot. That local experience shapes how we stage the job, where we park the truck, and how we protect your neighbors’ property. You won’t get a rotating crew of strangers. You’ll get Manny Cordero and a team that knows your street, your city’s permit process, and your roof’s exposure to the marine layer.
Our relationships with seven manufacturers, including GAF, CertainTeed, and Owens Corning, mean we don’t push one brand because it’s what we stock. We recommend the material that fits your home’s coastal exposure, your budget, and your long-term plans. That’s material choice, not salesmanship. Call (866) 974-2271 and we’ll walk you through the options that make sense for Manhattan Beach.
Styles & brands we work with






Reroofing in Manhattan Beach
Reroofing in Manhattan Beach means installing a new roof system over your existing roof, typically when the current roof has a single layer and the decking underneath is still sound. It’s common here on 1980s and 1990s homes where the original composition shingles are nearing the end of their life but the plywood below is still workable. A reroof in Manhattan Beach usually runs $11,000 to $21,000, depending on roof size, pitch, and whether the existing layer needs partial repair before we lay the new system over it.
When a Reroof Makes Sense
If your shingles are curling at the edges or losing granules but there’s no evidence of decking rot, a reroof can strip a layer of cost out of the project and get the job done in less time. We check the sheathing from the attic side before recommending this route, because Manhattan Beach’s coastal moisture can hide decking damage that a quick glance from the top misses.
Reroof Limitations in the Sand Section
Older bungalows in the sand section often carry multiple roof layers already, which rules out reroofing by code. When that’s the case, we’ll tell you directly and explain why a full tear-off is the only legal and safe path. We don’t layer over problems; we solve them the way the building department requires.
Flat Roof Replacement in Manhattan Beach
Flat roof replacement in Manhattan Beach differs from most of LA because the marine layer keeps low-slope roofs damp longer, so membrane selection and drainage matter more than they would inland. Many mid-century homes and duplexes here have low-slope or built-up roofs that need periodic full replacement. A flat roof replacement in Manhattan Beach typically costs $12,000 to $24,000, depending on square footage, parapet wall condition, and whether the decking under the membrane needs repair.
Membrane Options for Coastal Low-Slope Roofs
We recommend materials that handle constant moisture and salt exposure without delaminating. Torch-down modified bitumen and TPO both perform well on Manhattan Beach flat roofs when the seams are done right, and we walk you through the trade-offs on cost, lifespan, and heat reflection before you commit.
Drainage and Salt Corrosion
Flat roofs fail fastest at the low points where water sits. On Manhattan Beach flat roofs, we pay extra attention to scuppers, internal drains, and the metal flashing around roof edges, since ocean-facing metal corrodes visibly faster here than a few miles inland. Replacing corroded edge metal during a flat roof project is standard practice for us in the sand section.
Trusted Brands We Service in Manhattan Beach
We install products from seven industry-leading manufacturers, including GAF, CertainTeed, Owens Corning, and IKO. That roster matters for Manhattan Beach customers because different homes here need different material properties. A shingle that handles high wind and salt spray well on a west-facing Hill Section slope might be overkill for a shaded tree section bungalow. We stock local parts and order Manhattan Beach-specific materials fast, so your project isn’t waiting on a supply chain that treats coastal roofing as an afterthought. Your roof, your material choice. That’s the whole point of working with us.

AfterCommon Roof Replacement Problems We See in Manhattan Beach Homes
- Fastener corrosion on ocean-facing slopes. In the sand section, we routinely find roofing nails and fasteners rusted through within 10 to 15 years, with flashing and vents decaying electrolytically because salt-laden onshore wind accelerates metal failure. These leaks start small and spread under the shingles before you see a stain inside.
- Aging sheathing under multiple re-roof layers. Many 1950s Manhattan Beach bungalows have been re-roofed two or three times over original decking that was never meant to carry that weight. Nail pops, sagging between rafters, and compromised decking are common findings once we tear off the old layers.
- Wind-driven sand abrasion on west and south slopes. Sand from the beach acts like sandpaper on shingle granules, shortening roof lifespan by up to 30% on exposed slopes compared to inland Los Angeles. We see granule loss concentrated on the ocean-facing planes of homes within a few blocks of the water.
- Corroded drip edge and vents on original shake roofs. When we pull original wood shake off a 1950s beach bungalow, the ocean-facing drip edge is almost always pitted and failing. That hidden corrosion is why a Manhattan Beach tear-off quote should always include new edge metal, not reuse of what’s coming off.
Pricing for Roof Replacement in Manhattan Beach, CA
A full tear-off and replacement on a typical Manhattan Beach home costs $14,000 to $32,000. Asphalt shingle roofs on standard pitches land in the $14,000 to $22,000 range.

FAQs About Roof Replacement in Manhattan Beach
Salt air corrodes standard roofing fasteners, flashing, and vents faster in Manhattan Beach than inland, so we recommend corrosion-resistant fasteners and materials like GAF architectural shingles with upgraded metal components for ocean-facing slopes. On sand section homes, we specifically look for electrolytic decay between dissimilar metals and replace old flashing with materials designed for coastal exposure. Call (866) 974-2271 and we’ll explain which upgrades actually matter for your home’s orientation and distance from the water.
Yes, Manhattan Beach requires a building permit for roof replacement, and the process includes plan review, inspections, and compliance with the city’s coastal overlay requirements for certain properties. The complexity depends on your home’s zoning, whether you’re in the sand section or hill section, and what the inspector finds once the old roof comes off. We pull the permit, schedule the inspections, and handle the corrections ourselves, so you aren’t navigating city hall alone. Call (866) 974-2271 and we’ll tell you what your specific permit path looks like.
A square is 100 square feet of roof area, and a typical 1,800-square-foot Manhattan Beach home has between 22 and 30 squares depending on roof pitch and overhangs. Homes with roof decks, dormers, or complex footprints in the tree section often run more squares than their floor area suggests. We measure your actual roof planes from the attic and exterior, not from satellite imagery, so your quote reflects what’s really up there. Call (866) 974-2271 for a precise measurement and a line-item square count on your estimate.
We follow Manhattan Beach’s noise ordinance hours, stage materials in designated areas rather than blocking narrow sand section streets, and keep the job site clean at the end of every workday to respect your neighbors. On tight lots with shared walls, we coordinate access with adjacent homeowners before we start, and we keep the tear-off and nail-gun work within allowed hours. A considerate crew is part of doing business in a dense beach city, and our reputation in Manhattan Beach depends on it. Call (866) 974-2271 and we’ll walk you through how we stage your specific lot.
For ocean-facing Manhattan Beach homes, we recommend brands like GAF and CertainTeed architectural shingles paired with corrosion-resistant fasteners and upgraded flashing, while Owens Corning offers strong wind-rated options for exposed hill section slopes. The right brand depends on your roof’s pitch, orientation, and whether you want a specific look or warranty term. Because we install from seven manufacturers instead of one, we fit the material to your home rather than fitting your home to whatever we stock. Call (866) 974-2271 for a material recommendation based on your actual roof, not a sales script.
