Fast, Reliable Roof Replacement Across Montebello
Roof replacement in Montebello typically runs $8,500 – $16,000 for a standard single-story bungalow, depending on size, tear-off layers, and hidden decking repairs.

Call (866) 974-2271 to get a written line-item estimate from Manny Cordero and the Koreatown Roofing team.
We know Montebello’s streets, its older tract blocks, and the particular way these homes behave after 70 or 80 years under California sun. That local familiarity is what lets us price honestly and stage smartly, even when the side yard is barely wider than a wheelbarrow.
Why Koreatown Roofing Is Montebello’s Preferred Roof Replacement Company
Koreatown Roofing does one thing: roofing. Inspection, repair, and replacement. We’re not a general contractor squeezing your roof between a bathroom remodel and a patio cover. Every crew we send to Montebello works roofs full time, and the person who walks your property in Montebello is the same type of specialist who will run the job. Our Roof Replacement team handles tear-offs, decking, underlayment, and shingle installation as a single continuous process, not a series of subcontracts.
Montebello homeowners tell us the same thing: they want a roofer who actually answers the phone, shows up when scheduled, and doesn’t disappear when a surprise shows up under the old shingles. That’s the reputation Manny Cordero has built, and it’s tied directly to how we behave in neighborhoods like the streets south of Whittier Boulevard. We work where our customers live, and our name carries that weight.
Response time to Montebello is consistent because we schedule by neighborhood, not by whoever calls first. When you call (866) 974-2271, you speak with someone who can look at our Montebello schedule and give you a real date, not a vague window.
We also bring something few roofers do: material choice. We install GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. Seven manufacturers. That means your roof gets the product that fits your house and budget, not whatever single brand the contractor happens to stock. Your roof, your material choice.
Styles & brands we work with






Asphalt Shingle Roof Replacement in Montebello
Asphalt Shingle Roof Replacement in Montebello means tearing off whatever is up there now – often a layer of original wood shake, a layer of 1970s three-tab, and maybe a layer of rolled roofing on the back addition – and installing a clean, properly fastened shingle system. On Montebello’s 1920s – 1950s bungalows, we most often recommend architectural shingles for their wind resistance and the dimensional look that suits older Spanish and California bungalow styles.
A typical asphalt shingle tear-off and replacement on a Montebello bungalow runs $8,500 – $13,500, including disposal, underlayment, drip edge, and standard ridge venting. The final number moves based on square footage, how many tear-off layers are up there, and what the decking looks like once it’s exposed.
Architectural Shingles on Older Montebello Roofs
Architectural shingles carry a higher wind rating than basic three-tab, which matters when Santa Ana winds push through the Whittier Narrows and hit the older neighborhoods south of Beverly Boulevard. We use a six-nail pattern on most Montebello installs, not the minimum four, because the wind uplift on these exposed single-story roofs is real.
For homeowners deciding between three-tab and architectural, the price difference is usually $1,200 – $2,200 on a typical bungalow. Most Montebello owners choose architectural for the lifespan and the look.
Roof Decking Replacement on Back Additions
Back additions on Montebello homes – the enclosed porches and service rooms added in the 1940s and ’50s – frequently hide rotted 1×6 decking under original tar paper. When we tear off an asphalt roof and find spongy or delaminated sheathing, we replace it before anything else goes down. That cost runs $2.50 – $4 per square foot of decking replaced, and we price it in writing before installing a single new panel.
New Roof Installation in Montebello
New Roof Installation in Montebello usually means a full tear-off to bare framing, then building the roof back up correctly: decking repairs, ice and water shield in valleys, synthetic underlayment, shingles, ridge vent, and new flashing at every penetration. For homes that have been reroofed multiple times, this is often the only way to get a roof that drains right and holds up to summer heat cycling and winter rain.
A complete new roof installation on a Montebello home typically falls between $10,500 and $16,000. That includes the full system, not just shingles. If your home is one of the postwar tracts with a nearly flat main roof, the price shifts toward the higher end because flat sections need different materials and more careful drain detailing.
New Construction Roofing for Montebello Additions
When Montebello owners add a bedroom, an ADU, or extend a kitchen, the roof on that new section is a New Roof Installation from the framing up. We coordinate with the framing crew so the roof is designed to tie into the existing structure without creating a leak-prone transition. Materials match or upgrade what’s on the main house.
New construction roofing on Montebello lots means working inside tight setbacks. We stage materials carefully, sometimes using a conveyor over the house when the side yard is three feet wide, because there’s no other way to get sheathing and shingle bundles to the roof.
Flat Roofing on Original Montebello Additions
Original tar-and-gravel flat roofs on Montebello back additions often hide rotted sheathing that only shows after tear-off. When we replace a flat section, we strip the gravel, inspect the decking, and install a modern membrane with proper drain and scupper detailing. The cost for flat roofing replacement runs $9 – $14 per square foot installed, and we always write the decking allowance into the contract before starting.
Trusted Brands We Service in Montebello
We work with the brands you already trust: GAF, CertainTeed, and Owens Corning are the ones Montebello homeowners ask for most, and we also install Boral, IKO, Atlas, and Tamko when the job calls for them. Because we maintain relationships with seven manufacturers, we stock the components needed to match whatever system your home requires. No single-supplier dependency, no take-it-or-leave-it pitch. On Montebello jobs, that means we can usually have materials delivered and staged within a week of your signed estimate, even when the job needs specialty flashing or a specific shingle color.

AfterCommon Roof Replacement Problems We See in Montebello Homes
- Hidden rot under original tar-and-gravel. Flat roofs on back additions were built cheap, and decades of trapped moisture rot the sheathing underneath. The rot only shows after tear-off, which is why we write a decking allowance into every Montebello contract before work starts.
- Santa Ana wind lift on old shingles. Older Montebello roofs were often nailed with staples or the minimum pattern. When the Santa Anas blow through, edges lift and tear. Our standard is a six-nail pattern with proper starter strip so the edges stay down.
- Narrow side-yard staging. On streets south of Whittier Boulevard, the gap between houses is often three to five feet. That means plywood and shingle bundles get carried over the house or run on a conveyor. We plan material delivery around this from day one, so the job doesn’t stall mid-tear-off.
- Undersized framing at valleys and additions. We regularly find 2×4 rafters where modern code calls for 2×6 or better, especially in valleys and older additions. When a permit opens the structure, we price the framing upgrade in writing and get approval before touching it. The alternative is a new roof over a structure that can’t carry it.
Pricing for Roof Replacement in Montebello, CA
A standard asphalt shingle tear-off and replacement on a Montebello bungalow runs $8,500 – $13,500. A full New Roof Installation with decking repairs and flat sections typically lands between $10,500 and $16,000. The main cost drivers are roof square count (most Montebello bungalows run 12 – 18 squares, and you’re paying per square), number of tear-off layers, decking replacement at $2.50 – $4 per square foot, and whether the job includes a flat back addition at $9 – $14 per square foot.

FAQs About Roof Replacement in Montebello
We inspect the flat section during our initial estimate, but the honest answer is that rot hides until the gravel comes off. That’s why every Montebello contract includes a written decking allowance, usually $2.50 – $4 per square foot for replacement. If we find rot during tear-off, we photograph it, show you the scope, and get written approval before installing new sheathing. You’re never surprised by a charge you didn’t approve. Call (866) 974-2271 to schedule an estimate.
Yes. On narrow-lot tear-offs south of Whittier Boulevard, we run materials over the house with an electric conveyor, or hand-carry bundles through the alley where one exists. This is routine for our crews, and we build the staging plan into the schedule before the tear-off starts. The job doesn’t stop because the side yard is tight. Call (866) 974-2271 and we’ll walk your property and tell you exactly how we’d stage it.
The most common ones are ice and water shield at eaves and valleys, ventilation requirements that may force a ridge vent or additional intake venting, and flashing upgrades at penetrations and sidewalls. If the existing framing is undersized for the span, the inspector can require reinforcement. We handle the permit on every Montebello replacement and price code-required upgrades into the estimate up front. Call (866) 974-2271 for a written quote that includes permit scope.
Most Montebello bungalows run 12 to 18 squares. That matters because shingle pricing is per square, and it’s the fastest way to compare quotes: divide the shingle portion of any estimate by the square count and you’ll see who’s marking up materials. We’ll give you the square count on every estimate, in writing. Call (866) 974-2271 to get yours.
We install GAF, CertainTeed, and Owens Corning architectural shingles as the most common wind-resistant choices for Montebello homes, along with Boral, IKO, Atlas, and Tamko when the job calls for them. Architectural shingles carry higher wind ratings than three-tab, and we use a six-nail pattern on exposed single-story roofs where Santa Ana uplift is real. Ask us about wind ratings when you call (866) 974-2271 for your estimate.
If your Montebello roof is at the point where patches aren’t making sense, get a straight answer about what replacement will cost. We’ll walk the property, check the decking condition where we can, and give you a written line-item estimate with the square count, material brand, and permit scope spelled out.
