Trusted Roof Replacement for Koreatown Homeowners
Roof replacement in Koreatown is a serious investment, and the biggest mistake we see is homeowners getting pushed into a single brand they never chose. That’s not how this works. At Koreatown Roofing, we install seven different manufacturers, so you get the roof that fits your home, your budget, and the look you want. We’re led by Manny Cordero, a roofing specialist who built this company on straight answers and real material options. We do one thing: roofing. Inspection, repair, replacement. That’s the whole list. If you need a roofer in Koreatown who won’t upsell you into a brand we happen to stock more of, call us at (866) 974-2271 for a free estimate.
Key Takeaways
- Seven brands available: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. Your roof, your material choice.
- Roofing-only contractor: 100% of our jobs are roofing jobs. No handyman work, no general construction, no subcontracted crews.
- Free estimates: Call (866) 974-2271 and we’ll walk the roof, measure it, and give you a written line-item quote.

Styles & brands we work with






Roof Installation
Roof Installation is the process of setting a completely new roofing system on a structure, whether it’s a brand-new build or a full tear-off and replacement of the existing layers. In Koreatown, most roof installation jobs we handle are replacements on homes built between the 1920s and 1980s, which means we’re often dealing with older framing, multiple shingle layers, and decks that need repair before the new system goes down. Koreatown Roofing handles this from start to finish: tear-off, deck inspection and reinforcement, underlayment, flashing, and the new roofing material. A full roof installation in Koreatown typically runs $8,500 to $18,000 depending on square footage, pitch, material choice, and deck condition. We work with seven manufacturers, so the price you pay reflects the roof you chose, not the roof we happened to have in stock.
Full Tear-Off vs. Overlay
A full tear-off removes every layer down to the wood deck. An overlay puts new shingles over the existing layer. Codes in Los Angeles allow overlays in limited cases, but we rarely recommend them if the deck has any signs of sagging, water intrusion, or rot. A tear-off costs more up front but gives us a clean slate to find and fix hidden deck problems that would otherwise ruin the new roof early.
Choosing Materials That Fit the Structure
Some Koreatown roofs are too low-slope for standard asphalt shingles. Others can’t handle the weight of certain tile products without structural reinforcement. We evaluate pitch, framing capacity, and exposure to afternoon heat before recommending materials. That’s where having seven brands matters: you’re not forced into one product line that doesn’t match your house.
Roof Replacement Contractor
A Roof Replacement Contractor is a licensed professional who removes your old roof, repairs the deck underneath, and installs a new roofing system. The difference between a roofing specialist and a general contractor who “also does roofs” is what happens when things get complicated. Old Koreatown homes often have unexpected deck rot, non-standard rafter spacing, or chimney flashing that wasn’t done right in the first place. Koreatown Roofing does roofing every day, so these aren’t surprises to us, they’re just Tuesday. Manny Cordero leads every project with the same approach: inspect first, quote honestly, and never switch brands on you because a supply order didn’t arrive. A Roof Replacement – Los Angeles project in Koreatown generally runs $9,000 to $22,000 depending on material grade and roof complexity.
Why a Specialist Matters on Older Homes
Homes in Koreatown built before 1960 often have spaced sheathing instead of solid plywood decking. Modern shingle manufacturers require solid decking for warranty compliance. A generalist might lay shingles over spaced boards and create a leak problem the homeowner won’t discover for two years. We catch these issues before the first nail goes in.
Permits and Code Compliance
Los Angeles requires permits for full roof replacements, including reroofing jobs. We pull the permit, coordinate the inspection, and make sure the final installation passes on the first visit. If the inspector flags something, we fix it. That’s our job. You don’t chase down the city; we do.
Asphalt Shingle Roof Replacement
Asphalt Shingle Roof Replacement is the most common roofing job we do in Koreatown, and the material options are broader than most homeowners realize. You’ve got three-tab, architectural, and designer shingles across multiple brands, each with different lifespans, wind ratings, and aesthetic profiles. Koreatown Roofing installs asphalt shingle systems from GAF, CertainTeed, Owens Corning, IKO, Atlas, and Tamko, so the conversation starts with what your home needs, not what we’re trying to move. An asphalt shingle replacement in Koreatown typically costs $8,500 to $16,000 for a standard single-family home. The shingle grade, roof pitch, and number of penetrations like skylights and vents all move that number.
Architectural vs. Three-Tab Shingles
Three-tab shingles are the flat, single-layer classic. They’re cheaper but thinner, with shorter lifespans, usually 15 to 20 years in our climate. Architectural shingles are thicker, dimensional, and rated for 25 to 30 years or more, and they add visual depth to the roofline. Most Koreatown homeowners choose architectural-grade for the durability, and the price difference is often only $1,500 to $3,000 across the whole roof.
Heat and UV Exposure in Koreatown
Koreatown sits in a dense urban heat corridor. Afternoon sun beats on roofs for hours, especially on west-facing slopes. That heat accelerates shingle granule loss and sealant breakdown. We recommend shingle lines with higher UV and heat-resistance ratings for homes with unshaded western exposure. Certain manufacturers specifically engineer their products for this climate profile, and that’s a reason we keep multiple brands in the conversation instead of pushing one.
New Roof Installation
New Roof Installation refers to placing a roof on a property that either has no roof yet, as with a new addition or accessory dwelling unit, or needs the existing roof removed to the deck and completely rebuilt. Koreatown has seen a wave of ADU construction along with garage conversions, and many of these projects need a ground-up roofing system designed to tie into the main house. Koreatown Roofing handles new roof installation with the same care as any replacement: we assess the framing, specify the underlayment, install the chosen material, and make sure every transition point is flashed correctly. A new roof installation in Koreatown typically runs $10,000 to $25,000 depending on square footage, slope, and material selected.
ADU and Addition Roof Tying
When we tie a new structure’s roof into an existing roofline, the valley and transition flashing are where leaks appear if the work is rushed. We detail these junctions for water flow and drainage before we ever pick up a shingle bundle. That extra planning is the difference between a roof that lasts and one that stains the ceiling in two winters.
Deck Preparation and Underlayment
New installation only works as well as the deck beneath it. We check rafter spacing, replace any compromised wood, and lay a synthetic underlayment that holds up better than old felt paper in our wet season. If your deck has issues, this is the moment to fix them. Once the new material goes on, it’s too late to address what’s underneath without tearing it off again.
Reroofing
Reroofing is replacing an existing roof with a new one, and in most cases in Koreatown, it means a complete tear-off to the deck before new materials go down. The older the home, the more important the tear-off becomes. We find hidden damage regularly: rotted fascia boards, failed flashing around chimneys and vents, and sections of decking that have been wicking moisture for years. Koreatown Roofing does reroofing as a full system replacement, not a cosmetic shingle swap. A reroofing project in Koreatown generally runs $9,000 to $20,000 for a typical single-family home, depending on material grade, roof size, and how much deck work is required once we see what’s underneath.
When Overlay is Off the Table
Current Los Angeles building codes restrict reroofing overlays in most situations. If your roof already has two shingle layers, you’re not allowed to add a third. If the deck shows water damage or unevenness, an overlay would just hide the problem and shorten the life of the new material. We’ll tell you plainly: a tear-off costs more, but it gives you a warranty-backed installation on a solid base.
Repair-to-Replacement Continuity
If you’ve worked with us on roof repairs before, we already know your roof’s age, material, and problem areas. When it’s time to reroof, we don’t start from zero. That continuity means the replacement quote accounts for the full picture: what’s been patched, what’s been holding, and what needs to go. You can stay with one contractor across the entire lifecycle of your roof, and you should. In fact, take a look at our Roof Replacement in Koreatown page for a deeper dive on what the process looks like.
Flat Roof Replacement
Flat Roof Replacement covers low-slope or completely flat roofs, which are common on Koreatown’s multi-family buildings, commercial storefronts, and mid-century apartment complexes. These roofs are different systems entirely, usually built-up roofing, modified bitumen, or single-ply membranes like TPO. Standing water, UV breakdown, and failed seams are the three big reasons flat roofs fail. Koreatown Roofing evaluates the existing membrane, the drainage pattern, and the underlying insulation before recommending anything. A flat roof replacement in Koreatown typically runs $12,000 to $28,000 depending on the system chosen, the square footage, and whether the existing insulation needs to come out.
Membrane Selection and Fit
Not every flat roof should get the same membrane. TPO reflects heat well, which matters in Koreatown’s summer. Modified bitumen handles foot traffic better around HVAC equipment. Built-up roofs offer layered redundancy. We lay out the trade-offs for your building’s specific conditions and let you choose. Products from Boral and CertainTeed give us additional flat-roof options depending on the structural and drainage profile.
Drainage and Ponding Water
A flat roof that doesn’t drain is a flat roof that dies early. We check for low spots, inadequate scuppers, and clogged drains before installing anything. Sometimes the fix is adding tapered insulation to create slope. Sometimes it’s reconfiguring the drain locations. Either way, if we just lay a new membrane over a ponding problem, we’ve installed a future leak. We don’t do that. If you’re also weighing a full replacement versus repair, our home page connects you to our repair options too.
Brands We Service
We install and service roofing systems from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That’s seven manufacturers, and we chose that roster deliberately. Each brand has strengths. GAF’s Timberline line is a workhorse in Southern California, with strong wind ratings and wide color availability. CertainTeed’s Landmark shingles are consistently well-regarded for their dimensional profile and long-term granule adhesion. Owens Corning products bring their proprietary SureNail technology to the table, which holds shingles through high-wind events that hit the foothill canyons around Koreatown during Santa Ana season.
We also work with IKO and Atlas when the budget or aesthetic calls for them, and Boral for specialized tile and flat-roof systems. The point is this: no single supplier controls our recommendation. We look at your roof’s pitch, your home’s exposure, your budget, and the look you want, then match the manufacturer to the job. Whether you have a GAF roof that’s reached the end, or you’re comparing CertainTeed against Owens Corning for a full replacement, we can help you make an honest call. If you’re in a nearby neighborhood, our Roof Replacement in Silver Lake page covers the same material options for that side of town.

- Granules in the gutter or at downspout bases. Asphalt shingles shed granules as they age, but heavy granule loss means the protective surface is failing. In Koreatown’s heat, that accelerates quickly, and within a season the underlying mat starts cracking. If you see a pile of granules after every rain, you’re not imagining it; the roof is telling you it’s wearing out.
- Daylight through the attic boards. Go into your attic on a sunny day and look up. If you can see pinpoints of light, water can get in. Those holes often come from cracked shingles, failed flashing, or lifted seams. Any visible light through the roof deck means a leak is a matter of when, not if.
- Curling or buckling shingles. Shingles should lie flat. When they curl at the edges or buckle in the middle, the sealant bond is failing and the shingle is exposed to wind uplift. In Santa Ana conditions, a curled shingle becomes a flying shingle, and one missing shingle leads to water intrusion in the next rain.
- Water stains on ceilings or walls. By the time water shows up inside, it’s already traveled through the roof system. The entry point is rarely directly above the stain. Water runs along rafters, pools on drywall, and drips at the weakest point. This isn’t a patch job; it’s a signal that the system has been compromised long enough to saturate the deck.
- Sagging roofline or soft deck. If the roof plane doesn’t look straight when you sight down the ridge, something underneath is losing structural integrity. Soft spots underfoot mean rot. These conditions don’t self-correct, and they make the entire roof vulnerable to collapse under rain-saturated weight. Call a roofer before it gets worse.

How Much Does Roof Replacement Cost in Koreatown?
A typical asphalt shingle roof replacement costs $8,500 to $16,000 in Koreatown for a single-family home under 2,000 square feet. Larger homes or steep-pitch roofs push that to $15,000 to $22,000. Flat roof replacements run higher due to membrane and insulation costs, typically $12,000 to $28,000. A new roof installation on an ADU or garage addition generally lands between $10,000 and $20,000 depending on size and material choice. These are real ranges from jobs we’ve quoted and completed in Koreatown, not national averages.
What moves the price: roof size, pitch, number of layers being torn off, deck condition, material grade, number of penetrations (skylights, vents, chimneys), and whether the home requires structural reinforcement. Flat roofs also vary by membrane type and insulation thickness. The cheapest quote is rarely the best deal, but neither is the most expensive. The best value is a quote that explains exactly what you’re paying for, and that’s what we write. Our free estimates include material options, deck assessment, permit costs, and a clear breakdown.

Frequently Asked Questions About Roof Replacement in Koreatown
Roof replacement is the removal of the existing roofing material down to the deck, followed by installation of a new roofing system. It’s different from repair, which patches isolated problem areas. In Koreatown, a replacement is the right call when the roof has reached the end of its rated service life, when leaks are widespread, or when the deck underneath needs significant work. Call (866) 974-2271 and we’ll inspect your roof to tell you honestly whether you need replacement or if a repair can buy you more time.
Most single-family roof replacements in Koreatown take 2 to 4 days on site. Flat roofs and larger multi-family buildings can run 5 to 10 days depending on system complexity and weather. Tear-off, any deck repairs, underlayment, and new material installation all factor into the schedule. We’ll give you a firm timeline in the written estimate, and we show up on the day we say we will.
An asphalt shingle roof replacement in Koreatown typically costs $8,500 to $16,000 for a standard single-family home. Flat roofs run $12,000 to $28,000, and complex or steep-pitch roofs land on the higher end of those ranges. Materials, deck condition, home size, and penetration count all affect the final number. Your free written estimate will break down every cost line by line, so call (866) 974-2271 to get your exact price.
Yes. We install GAF, CertainTeed, and Owens Corning products, along with IKO, Atlas, Tamko, and Boral. That’s seven manufacturers, and we don’t push you toward one because of a supply contract. The brand we recommend depends on your roof’s pitch, your home’s exposure, your budget, and the look you want. We work with brands you already trust, and the choice stays yours.
If your roof has an active leak from storm damage or sudden failure, call us at (866) 974-2271. We’ll assess the situation and get someone out to stabilize the problem. We don’t promise same-day service on full replacements; those take planning, materials, and permits. But we move fast on emergency tarping and temporary protection to stop the water, then schedule the permanent fix.
Manufacturer warranties cover the materials, and we make sure your installation meets every manufacturer requirement so that warranty stays valid. Our own workmanship is backed by our reputation in Koreatown, which is built on roofs that don’t leak. For specific warranty terms on your chosen material, ask Manny Cordero during your estimate. He’ll walk through exactly what’s covered and for how long, with no fine print surprises.
Clear the driveway and any parking areas directly adjacent to the house. Move vehicles, patio furniture, and anything fragile away from the work zone. We’ll protect landscaping as best we can, but roof tear-off produces debris, and clear access makes the job faster and safer. If you have attic items that might get dusty, cover them with a sheet. We’ll handle the rest, including cleanup and nail sweeps.
