Roof Replacement in Los Angeles — Written Price, Workmanship Warranty

Fast, Reliable Roof Replacement Across Los Angeles

A full roof replacement in Los Angeles typically runs between $11,500 and $28,000 for asphalt shingles, and $22,000 to $47,000 for tile or flat built-up systems, depending on the tear-off scope, decking condition, and fire-rating requirements in your specific ZIP code. Our Roof Replacement team works throughout Los Angeles, from the 1920s bungalows south of the 10 to the hillside homes in Silver Lake, and we quote the job based on what’s actually under the existing roof, not a generic per-square number. If you’re weighing a re-cover against a full tear-off, call (866) 942-4187 and we’ll walk you through what your roof needs, not what we’d prefer to sell.

Call (866) 942-4187

Los Angeles poses a specific set of problems for roofing that most other cities never see: months of relentless UV cooking asphalt and underlayment, Santa Ana winds testing every nail and flashing detail, and fire-safety requirements that a lot of out-of-town roofers simply don’t understand. You need a contractor who knows which LA neighborhoods fall inside the Very High Fire Hazard Severity Zone and what that means for the quote you’re about to sign. That’s the work we do every day.

Why Orange County Roofing Co Is Los Angeles’s Preferred Roof Replacement Company

Kurt Hensley has built Orange County Roofing Co around a simple principle: carry enough product lines that we never have to steer a homeowner toward a brand just because it’s the only one we can buy. We install GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That’s seven competing manufacturers under one roof, which means when we recommend a specific shingle or tile for your Los Angeles home, the recommendation is based on the house, the exposure, and the fire-zone requirements. Not on our margin.

For Los Angeles customers specifically, that brand-neutral position matters in ways it doesn’t in most markets. A flat built-up roof in ZIP 90037 has completely different fire-assembly needs than a steep-slope architectural shingle roof in Echo Park. A Spanish-tile job near West Adams needs ember-resistant flashing at every roof penetration. Having access to multiple manufacturer lines means we can specify materials that actually comply with LAFD and CAL FIRE requirements in your zone, documented for your insurer. Most one-brand roofing companies can’t do that honestly.

We also offer inspection as a standalone service. If you’re selling a 1938 bungalow in Jefferson Park or buying a mid-century flat-roof house in Koreatown, you can schedule a roof inspection without any obligation to hire us for replacement. The inspection report tells you exactly what’s there: decking condition, layer count, flashing integrity, and whether the current assembly would survive an ember event. That’s a diagnostic, not a sales lead-in.

Asphalt Shingle Roof Replacement in Los Angeles

Asphalt Shingle Roof Replacement in Los Angeles is usually the most cost-effective path for older wood-framed bungalows and modest single-story homes in central and south LA, where the roof pitch supports shingles and the budget calls for a full tear-off without the weight of tile. For these homes, expect to pay $11,500 to $19,000 for a standard architectural shingle replacement on a 1,400 to 1,800 square foot roof, including tear-off, decking repair where needed, underlayment, and new flashing. Architectural shingles from Atlas, CertainTeed, or Owens Corning dominate this market because they carry higher wind-uplift ratings than three-tab, and in Santa Ana territory that rating is not optional.

What most homeowners don’t realize is that the shingle is only as good as the nailing pattern. A shingle labeled for 130 mph uplift in Los Angeles means nothing if the installer uses the wrong fastener schedule or skips starter strips. We document the manufacturer’s nailing pattern on every job, because when an insurer asks for proof of a rated assembly after a wind claim, the paperwork either backs you up or it doesn’t.

Full Tear-Off vs Overlay

In older south-central and central LA neighborhoods like West Adams and Jefferson Park, a lot of roofs already have two or three layers of shingles or built-up roofing stacked over original 1920s or 1940s decking. We strongly recommend a full tear-off in these situations, and we’ll tell you why in plain terms: you cannot see soft sheathing or failed valleys under three layers of roofing. Laying a fourth layer hides the problem and voids the fire-rated assembly your insurer expects for a home in a Very High Fire Hazard Severity Zone.

A full tear-off also gives us the chance to inspect and replace roof decking where termites or decades of heat have compromised the wood. Los Angeles bungalows are notorious for this. We’d rather show you the rotted deck board and quote the repair honestly than cover it and have your new roof fail in five years.

Fire-Rated Underlayment and Ember Details

For any home in LAFD’s designated high-fire zones, including much of the south and central LA flatlands, the underlayment choice is a code-level decision, not an upsell. We install fire-rated synthetic underlayment and ember-resistant flashing at eaves, rakes, and penetrations as standard practice on these homes, because that’s what a Chapter 7A-compliant assembly requires. Your quote from us will list these as line items. A cheaper quote that omits them is not cheaper. It’s incomplete.

New Roof Installation in Los Angeles

New Roof Installation in Los Angeles covers two situations: a full replacement on an existing house where the old roof is removed to the deck and rebuilt, and true new construction where we install the roof on a new build or an addition. The cost range is broader here: $16,000 to $47,000 for most Los Angeles homes, with adobe or Mediterranean-style tile roofs at the upper end and architectural shingle roofs at the lower. What drives the number is decking repair scope, roof complexity (valleys, dormers, multiple ridges), and the fire-rating level required in your zone.

New construction in Los Angeles has its own permit and inspection timeline. The city reviews roofing as part of the overall building plan, and depending on the fire zone, that review includes roof covering classification, eave and vent details, and sometimes the underlayment spec. We handle the roofing permit scope and coordinate with the LADBS inspector on every new construction job. You should not have to be the go-between.

Architectural Shingle Systems

Architectural shingles are the default choice for new Los Angeles builds where the architect hasn’t specified tile or a flat membrane. They’re lighter than tile, faster to install, and several manufacturers build them explicitly for high-wind markets. The key is matching the shingle to the roof pitch and the wind-uplift zone. A roof in the Hollywood Hills with full Santa Ana exposure needs a different nail schedule than a low-slope roof tucked behind a taller structure in Koreatown.

Flat Roofing and Built-Up Systems

Flat and low-slope roofs are everywhere in central and south LA, especially on 1920s through 1950s commercial strips and the small apartment buildings that line Western and Vermont Avenues. These are mostly built-up hot-mop systems or modified bitumen. For these, the roofing membrane spec and the fire-zone requirements drive the cost more than anything else, and a full tear-off is almost always the right call, because we routinely find three or four layers of old roofing over deteriorated sheathing on these buildings. Laying another cap sheet over a failed core is how flat roofs in Los Angeles die young.

Trusted Brands We Service in Los Angeles

We’re authorized to install and service roofing products from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That’s seven major manufacturers, and we stock the most common replacement parts from each one, which means a warranty claim or a repair request in Los Angeles doesn’t stall while we wait on a distributor. When we recommend a specific brand for your Los Angeles roof, it’s because that product’s rating profile matches your exposure: an Atlas StormMaster for high-wind exposure in the hills, a Boral tile for a Spanish-style re-roof near Arlington Heights, or a CertainTeed Landmark for a straightforward shingle replacement in ZIP 90038. The right material for your roof, backed by the manufacturer’s own warranty.

Common Roof Replacement Problems We See in Los Angeles Homes

• Layered re-roofs hiding failed decking. On a 1928 Spanish-tile bungalow off West Adams Boulevard in ZIP 90007, our crew pulled the original clay tile and found three generations of patched underlayment over skip-sheathing that had gone soft at the valleys. We tore off to the decking, replaced the compromised boards, installed a fire-rated underlayment and new drip edge, then reset the tile with ember-resistant flashing at every penetration and a documented Class A assembly for the homeowner’s insurer. That’s the kind of thing an overlay would have buried forever.
• Unpermitted patio and carport roofs tied into the main structure. South and central LA have decades of add-on roofs that were never permitted and never flashed correctly. When we tear off the main roof, we often find these add-ons draining onto the house roof, with the connection point leaking into the wall. A legitimate replacement has to address these tie-ins, not shingle over them.
• Wrong nailing patterns that void wind ratings. We’ve seen architectural shingles labeled for 130 mph uplift installed with the wrong fastener schedule on exposed LA hillsides. The shingle itself was fine. The installation wasn’t. The homeowner thought they had a wind-rated roof; they had a product warranty and no assembly rating. When an adjuster checks after a Santa Ana event, that distinction decides the claim.
• Valley and flashing failures from deferred maintenance. Because Los Angeles gets so little rain, flashing problems go unnoticed for years. Then a single intense winter storm arrives, and every old valley, pipe boot, and chimney flashing reveals itself at once. By the time we’re called, the leak has often been active inside the wall for months. A replacement done right includes replacing every flashing point, not just the field of shingles.
