Our Roof Replacement & Installation Services in Los Angeles
Full Roof Replacement
Los Angeles’s dominant housing forms - 1920s-1940s Spanish Colonial Revival bungalows and 1950s-1970s flat-roof stucco apartment buildings - mean our full replacement work here centers on clay and concrete tile systems and built-up or modified-bitumen flat roofs, not the asphalt-shingle steep-slope work that defines most U.S. markets. We recently handled a 1930s Spanish Colonial in the Hollywood Hills where the owner noticed interior water stains during a December rainstorm. The clay tiles looked fine from the street, but our inspection revealed the #30 underlayment had degraded from decades of UV and heat, while the tiles themselves were still good. We performed a full underlayment replacement with a Class A fire-rated synthetic underlayment, re-bedded the ridge caps, and retrofitted ember-resistant vents to meet Very High Fire Hazard Severity Zone code - all without replacing a single tile.
Tile Roofing
On LA’s enormous inventory of Spanish-style tile roofs, the clay or concrete tiles routinely outlast the felt underlayment beneath them by 10-15 years. A 20-year-old tile roof often looks intact from the street while the underlying #30 felt has cracked and failed from UV and heat cycling. Savvy Los Angeles roofers lead with an underlayment inspection pitch rather than a tile replacement pitch, because the real failure mode is invisible from the curb and almost always misdiagnosed by homeowners. We inspect what’s beneath the tiles before we quote a single replacement.
Flat Roofing
LA’s massive post-war inventory of stucco apartment buildings carries torch-down or built-up flat roofs that take a beating from San Fernando Valley heat regularly exceeding 100°F. Year-round intense UV accelerates the degradation of roofing membranes well beyond what coastal climates produce. Annual Santa Ana wind events generate gusts exceeding 60 mph across hillside communities, routinely lifting aged edges and unseating flashing. We install modified bitumen, TPO, and PVC systems rated for LA’s thermal cycling and fire code requirements.
New Construction Roofing
Whether you’re building in Echo Park or adding an ADU in Silver Lake, we install new construction roofing that meets Los Angeles’s specific code requirements, including Class A fire-rated assemblies for hillside properties in Very High Fire Hazard Severity Zones. Our crews coordinate directly with your general contractor and city inspectors to keep permits moving.
Asphalt Shingles
While asphalt shingles aren’t LA’s dominant roofing material, we install them for homeowners in flatter neighborhoods like Koreatown and View Park-Windsor Hills who want cost-effective protection with strong warranty coverage. We’re authorized installers for GAF and CertainTeed systems.
Metal Roofing
Metal roofing is gaining ground in Los Angeles for its Class A fire rating and reflective properties that reduce cooling loads in Valley-adjacent neighborhoods. We install standing seam and metal tile systems that meet LA’s seismic and wind-load requirements.

Trusted Brands We Service in Los Angeles
We’re authorized installers for GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral - seven manufacturer lines, no substitutions. For Los Angeles homeowners, this means we stock the specific clay and concrete tile profiles, fire-rated underlayments, and ember-resistant venting components your job requires, not whatever’s cheapest this week. Our warehouse carries Boral and GAF products common to LA’s Spanish Colonial and Craftsman housing stock, so we’re not ordering specialty materials mid-job and leaving your roof open an extra day. Most replacements move from tear-off to final inspection without delay.
Common Roof Replacement & Installation Problems We See in Los Angeles Homes
- Underlayment failure hidden behind intact tiles: UV and heat cycling degrade felt underlayment years before tiles show wear, causing sudden leaks during winter storms. LA’s rainfall is highly concentrated December through March, so roofs go 8+ months without water exposure, allowing small failures to go undetected until damage appears inside.
- Seismic load concerns on heavy clay tile roofs: Original 1920s-1940s framing may not meet current CBC requirements, requiring structural review before a replacement. Heavy clay tile on original rafter spacing raises load concerns that roofers in most other markets never encounter.
- Santa Ana wind damage: Gusts over 60 mph lift aged tile edges and unseat ridge caps, leading to widespread failures on hillside properties from Hollywood Hills to Sunland-Tujunga. We inspect for wind-lifted tiles after every major event.
- Flat roof membrane degradation from thermal cycling: LA’s combination of intense summer heat and winter rain exposure causes built-up and modified-bitumen roofs to crack at seams and penetrations. The dry summer masks the damage until the first winter storm.

FAQs - Roof Replacement & Installation in Los Angeles
You likely need underlayment replacement, not full tile replacement. On most older LA tile roofs, the clay or concrete tiles outlast the felt underlayment beneath them by 10-15 years, so the visible surface looks intact while the hidden layer has cracked from UV and heat cycling. We inspect beneath the tiles first, and if they’re sound, we replace the underlayment with modern fire-rated synthetic material and re-bed the ridge caps - saving you thousands over a full replacement. Call (877) 367-1429 to schedule an inspection with photo documentation.
Properties in state-designated Very High Fire Hazard Severity Zones, including much of the Hollywood Hills, Bel Air, Topanga, and Sunland-Tujunga, must use Class A fire-rated roofing assemblies with ember-resistant venting. This typically means clay or concrete tile with approved underlayment, or certain metal and asphalt shingle systems rated for Class A exposure. We handle the permit submittal and inspector coordination for VHFHSZ compliance. Call (877) 367-1429 to confirm your property’s specific requirements.
Original 1920s-1940s framing may not meet current California Building Code load requirements for heavy clay tile, so we conduct a structural review before specifying materials. In some cases, we specify lighter concrete tile or alternative Class A systems that reduce dead load while maintaining fire rating and appearance. We never install a roof your structure can’t support. Call (877) 367-1429 and we’ll assess your specific framing during the estimate.
LA’s intense UV and heat degrade flat roof membranes year-round, but the damage stays hidden until winter rain finds the cracks. Built-up and modified-bitumen roofs expand and contract daily through thermal cycling, and after a long dry summer, seams and penetrations have often opened enough to allow major leaks once December storms arrive. We inspect flat roofs with infrared and core sampling to find degradation before it becomes interior damage. Call (877) 367-1429 for a seasonal inspection - our $89 tune-up catches these failures early.
Yes, the City of Los Angeles requires a building permit for all roof replacements, with additional fire department review for properties in Very High Fire Hazard Severity Zones. We pull permits as part of our standard process and coordinate all inspections, including the final sign-off required to close the permit. You won’t need to visit the Department of Building and Safety yourself. Call (877) 367-1429 and we’ll handle the paperwork.
