Roof Replacement in North Hills — Written Price, Workmanship Warranty

Fast, Reliable Roof Replacement Across North Hills

Roof replacement in North Hills usually runs $9,500 – $14,800 for a typical 1,400 – 1,800 sq ft single-story ranch with architectural asphalt shingles, and $11,500 – $17,800 when you’re also reroofing a detached garage or rear shop on the same lot. Most North Hills homes were built between 1955 and 1975, which means the original roof is long gone and the second layer, often a 1990s re-roof, is now at the end of its life. We reach North Hills within one business day for estimates, and we quote per structure, not per parcel, because so many lots here carry more than one roof.

Why Koreatown Roofing Is North Hills’s Preferred Roof Replacement Company

Koreatown Roofing does one trade: roofing. We’re not a general contractor squeezing a roof between a kitchen remodel and a room addition. Every crew we send to North Hills works exclusively on roof inspection, repair, and replacement, which means the person walking your roof off Sepulveda Boulevard understands decking, slope, valley flashing, and UV degradation the way a specialist should. Manny Cordero built the company around that focus, and it shows in how we scope North Hills jobs.

North Hills customers tend to call us in two situations. First, after a Santa Ana wind event, when a south- or west-facing slope has peeled back and the shaded north slope still looks fine. Second, when a home inspection flags a 40-50 year old roof during a sale. Both scenarios demand honest assessment, not a scare quote. We show you what’s actually failing, which structures on the lot need work, and what can wait. That’s the kind of straight talk that keeps our North Hills reputation tied to the neighborhoods we work in, not to a call center in another state.

We work with seven roofing manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. A North Hills homeowner should be able to compare shingle weights, wind ratings, and warranties instead of taking whatever one brand happens to have in stock. Your roof, your material choice. That’s the whole point.

Reroofing in North Hills

Reroofing in North Hills is rarely a simple layover job, because the 1950s-1970s tract homes off the 405 and Sepulveda corridor were built with original wood-shake or early asphalt roofs that have already been re-roofed once in the 1990s. That means a second layer is often hiding decayed decking, dried-out underlayment, and fastener failure that only shows up at tear-off. A full reroof here runs $8,900 – $13,200 on the main house, depending on whether decking replacement is needed. We don’t quote a layover without knowing what’s underneath, because on these roofs, what’s underneath is usually the problem.

Why Layovers Rarely Make Sense in North Hills

Layering new shingles over an old heat-baked roof adds weight and hides damage. In North Hills, summer roof-surface temperatures routinely push past 150°F, which accelerates aging on the bottom layer even while the top looks new. Most North Hills reroofs are full tear-offs down to the decking, which lets us catch rotted sections and replace them before they become a leak under a brand-new roof.

Decking and Underlayment on 40-50 Year Old Homes

If your North Hills home has its second roof from the 1990s, the decking underneath may have survived one full replacement already. The third roof on these homes is typically when decking failure shows up, especially near valleys, plumbing penetrations, and any flat section over a carport or addition. We price decking replacement per sheet so you know the worst-case number before tear-off starts, not after.

Flat Roof Replacement in North Hills

Flat roof replacement in North Hills is a common need on the low-pitch sections over carports, patio covers, and room additions attached to the original ranch footprint. On these flat or low-slope sections, ponding water is rare given the Valley’s near-zero rainfall, but the real enemy is prolonged UV exposure. A flat roof replacement here typically runs $6,500 – $11,800 depending on square footage, number of penetrations, and whether we’re replacing the decking underneath. We scope flat sections separately from the pitched main roof, because they fail on a different timeline.

The UV Problem on Flat Sections

Flat roofing membranes in North Hills take direct sun from June through October with almost no cloud cover. That’s why we see membrane shrinkage at the edges, brittle flashing at parapet walls, and cracked sealant around vents and AC curbs. Flat roof replacement here is not about storm damage. It’s about heat and sun slowly cooking the membrane until it splits.

One Address, Multiple Flat Sections

Many North Hills lots have a flat roof over the carport and another over a rear addition or ADU. Each one needs its own takeoff, its own slope assessment, and its own quote. Bundling them into one project usually saves on hauling, dump fees, and mobilization, because we’re already on the lot. But we’ll always break the numbers out per structure so you can see exactly what each part costs. Call (866) 974-2271 for a free per-structure estimate.

Trusted Brands We Service in North Hills

Koreatown Roofing installs products from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That’s seven manufacturers, which means when a North Hills homeowner asks about GAF architectural shingles versus Owens Corning Duration versus CertainTeed Landmark, we can show actual options, not a take-it-or-leave-it pitch. We don’t have a single-supplier contract pushing one brand on every roof. We recommend based on wind rating, UV resistance, and budget fit for the specific slope and exposure on your home. If a brand matters to you, tell us. We work with the brands you already trust.

Common Roof Replacement Problems We See in North Hills Homes

• South- and west-facing slope failure after Santa Ana winds. Heat-embrittled shingles peel back ridge-to-eave on the sun-blasted exposures while shaded north slopes look almost new. A bid based on overall roof age misreads this failure mode, so we scope by compass face, not just by square footage.
• Hidden decking decay under the 1990s re-roof layer. The second roof on these 40-50 year old tract homes often conceals rotted decking, dried-out underlayment, and failing fasteners. We won’t know the full scope until tear-off, but we’ll price the worst case upfront so you’re not surprised mid-project.
• Detached outbuildings aging differently than the main house. North Hills lots frequently carry a detached garage, rear shop, or ADU with its own roof, slope, and age. Each structure needs its own takeoff and its own permitting line, because reroofing the house doesn’t automatically cover the outbuilding.
• Grading and drainage pushing water against outbuilding walls. Open lots with detached shops and ADUs often have grading that channels runoff toward the outbuildings. A new roof on the main house won’t fix water wicking into a shop wall or undermining an ADU foundation at the low end of the lot.
