Fast, Reliable Roof Replacement Across Mayflower Village
Roof replacement in Mayflower Village runs $9,500 to $22,000 for a typical 1,200 to 1,800 square foot single-story home, with asphalt shingle tear-offs landing between $7.50 and $11 per square foot and concrete tile replacements closer to $14 to $19 per square foot. That range moves based on decking repairs, permit-triggered upgrades, and how much hand-carrying the crew has to do around your side yard. We’re Koreatown Roofing, and we do one thing: roofing. If you’re on a 1920s or 1950s bungalow street near Olive Avenue or Duarte Road and the county just flagged your underlayment, call us at (866) 974-2271 for a free written estimate.
We know Mayflower Village not as a dot on a map but as a specific place where LA County rules, mature oak canopies, and small lots all shape how a roof job goes. The estimate you get from us reflects what we’ll actually find under the old tile, not a generic square count that changes on day two.
Why Koreatown Roofing Is Mayflower Village’s Preferred Roof Replacement Company
We’re a roofing-only contractor, which matters more in Mayflower Village than most places. The homes here are mostly 1920s to 1960s bungalows and ranch houses with wood-frame roofs, original concrete tile, or later asphalt shingle overlays. A general contractor who does kitchens, bathrooms, and the occasional roof won’t know what LA County’s pre-permit inspection looks for on a 70-year-old bungalow. We do, because every job we take is a roof job.
Our reputation in the 91006 zip code is built on transparency about what a tear-off actually uncovers. Homeowners here regularly tell us the same story: the roof looked okay from the street, but leaf litter from the mature oaks had been packing the valley flashings for years, and the underlayment underneath was gone. When that’s what we find, we document it, price it, and get written approval before we proceed. No surprises that show up as a line item after the fact.
We work with seven manufacturers, including GAF, CertainTeed, Owens Corning, and IKO, so if you want to match the original concrete tile look with architectural shingles, we’ll show you options from people you already know. Your roof, your material choice. That’s how we operate.

Roof Replacement Contractor in Mayflower Village
A Roof Replacement Contractor in Mayflower Village has to contend with one thing that contractors in incorporated cities don’t: permits run through LA County, and the county’s pre-permit inspection often turns up unpermitted prior additions and overloaded roof structures hidden above those original 1920s bungalow ceilings. That inspection can change the scope before we even start tearing off. We plan for it from the first walkthrough, because we’ve done enough jobs here to know the county often requires structural reinforcement or fire-rated underlayment once dry-rotted fascia or undersized rafters come into view.
What a Full Tear-Off Involves
When you replace a roof in Mayflower Village, we don’t just lay new material over the old. We tear down to the decking, inspect what’s underneath, and replace what’s failed. That means the old concrete tile or asphalt shingles come off, the sheathing gets checked for rot and cracks, and new underlayment goes down before the new roof does. On a 1948 bungalow we worked on near Olive Avenue, the original concrete tile hid a failed underlayment and cracked sheathing across the entire south slope. Once we tore off, we found the decking baked brittle by decades of 95°F+ summers. We upgraded the drip edge, added ice and water shield in the valleys, and priced the decking repairs and new flashing in writing before touching another shingle. The homeowner approved the change order that same afternoon and the job stayed on schedule.
When Mayflower Village Homeowners Need This
The call usually comes after the first real winter storm. Gutters packed with oak leaf litter back up, water overflows into the fascia, and suddenly a ceiling stain appears in the living room. By the time you see the stain, the underlayment has often been failing for years. If your home still has its original concrete tile from the 1950s or 60s, the visible tile may look fine while the waterproofing underneath is gone. That’s a tear-off, not a patch. We’ll tell you that straight, even when a patch would be cheaper for you today and easier for us to sell.
Asphalt Shingle Roof Replacement in Mayflower Village
An Asphalt Shingle Roof Replacement in Mayflower Village typically runs $9,500 to $16,000 for a standard single-story bungalow, of which material is roughly a third and labor plus tear-off the rest. Shingles work well on the shallow pitches common to this neighborhood’s ranch homes, and they let you move away from aging concrete tile at a fraction of the weight. That weight difference matters on older framing that was never sized for today’s code, which brings us back to the county inspection point.
Architectural Shingles vs. Three-Tab
Most Mayflower Village homeowners choose architectural shingles once they see them held up next to three-tab. The dimensional profile does a better job mimicking the shadow lines of the old concrete tile that characterizes the neighborhood, and brands like GAF, CertainTeed, and Owens Corning all make architectural lines that carry 30 to 50-year material warranties. Three-tab is thinner, cheaper today, and wears out faster under the San Gabriel Valley sun. We’ll quote both and let you decide.
Decking and Underlayment Realities
Here’s the truth most estimates won’t tell you: on a 1940s or 1950s home in Mayflower Village, there’s a real chance the roof decking under your old shingles is compromised. Oak leaf litter accumulates in the valleys, traps moisture, and rots the sheathing from the top down. Add decades of 95°F+ afternoons baking the south and west slopes, and you get plywood that crumbles when you pull the old nails. We write a decking allowance into every Mayflower Village quote, and we show you photographic proof of any decking we say needs replacing. That’s how it should work.
Trusted Brands We Service in Mayflower Village
We’re not tied to one manufacturer, and that’s on purpose. We install products from GAF, CertainTeed, Owens Corning, and IKO, along with three other major brands, so your material recommendation comes from what fits your roof and budget, not from whatever we happen to have a supply deal on. If you’re replacing concrete tile with architectural shingles, we can show you CertainTeed’s Landmark line next to GAF’s Timberline next to Owens Corning’s Duration, all priced out for your specific roof. We keep local stock and ordering channels open for Mayflower Village jobs, which keeps material lead times short. No single-supplier dependency. Your roof, your material choice.

AfterCommon Roof Replacement Problems We See in Mayflower Village Homes
- Hidden water damage under original concrete tile. The tile looks intact from the curb, but the underlayment underneath failed years ago. Once we tear off, we find rot along the valleys and eaves that wasn’t visible during the estimate walkthrough.
- Permit-driven scope changes from LA County. Since Mayflower Village is unincorporated, LA County handles permits. Their inspection can require structural reinforcement or fire-rated underlayment when the tear-off exposes undersized rafters or dry-rotted fascia, which changes the quote.
- Tight access and staging limits. The narrow side-yard setbacks and mature Chinese elms on many lots mean tear-off debris can’t just get tossed into a dump trailer parked at the curb. Crews hand-carry or hoist material, and that labor is real line time.
- Leaf-littered valleys and gutters. Decades of oak leaf drops pack the valley flashings and hold moisture against the underlayment. The first storm of winter is usually what sends the homeowner to the phone, because the backed-up valley finally leaks.

FAQs About Roof Replacement in Mayflower Village
Yes. Because Mayflower Village is one of the San Gabriel Valley’s unincorporated communities, roof replacement permits run through LA County’s building department, not a city hall. The county requires a permit for any full tear-off and re-roof, and their pre-permit inspection can flag structural issues that change the scope. We handle the permit paperwork for you and build the county’s typical inspection requirements into our quote. Call (866) 974-2271 and we’ll explain exactly what applies to your street.
A “square” is roofing shorthand for 100 square feet of roof surface. So if your bungalow has a 1,600 square foot roof, your quote will reference roughly 16 squares. Asphalt shingle replacement in Mayflower Village runs about $750 to $1,100 per square installed, including tear-off of the old material. When you see a per-square line item, multiply it by the square count to sanity-check the total. We break every quote down this way so you can compare us to any other bid without getting confused.
Because the mature oaks and elms that shade these streets drop leaf litter that packs the valleys and gutters, holding moisture against the wood sheathing for years. Add summer temperatures regularly over 95°F baking the south and west slopes, and the plywood or plank decking under your old roofing often fails. You can’t see it until the old tile or shingles come off. That’s why we include a decking allowance in every Mayflower Village estimate and document any replacement with photos before we charge for it.
Yes, usually quite well. Architectural shingles from GAF, CertainTeed, and Owens Corning have dimensional profiles that replicate the shadowed, stepped look of the original concrete tile common on 1940s and 1950s Mayflower Village bungalows. Color matching is easy since we carry samples from multiple brands. The benefit is weight: architectural shingles weigh far less than concrete tile, which matters on framing that’s been carrying that tile for 70 years. Call (866) 974-2271 and we’ll bring samples to your doorstep.
We photograph what we find, write a specific line-item change order for the added scope, and get your written approval before any additional work begins. If we find rotted decking, failed underlayment, or flashing that needs replacing, you see the cost before we spend it. On a 1948 bungalow near Olive Avenue, we found the entire south slope baked brittle and priced the decking replacement, drip edge upgrade, and new valley flashing in writing. The homeowner approved that afternoon and the job stayed on schedule. That’s how we run every Mayflower Village job.
