Trusted Roof Replacement & Installation for Los Angeles Homeowners
A full roof replacement in Los Angeles typically costs between $12,000 and $28,000 depending on materials and square footage, and most Ridgeline Roofing Co. jobs are completed in 1-3 days with no surprise charges. We’ve been replacing and installing roofs across Los Angeles since 1984, and our live phones are answered 24 hours a day at (844) 563-1816. If your roof is past 20 years, showing leaks, or losing granules after another hot summer, we’re the local crew that shows up, documents what we find with photos from your actual roof, and gives you an upfront price that matches the final invoice.
Los Angeles punishes roofs like few other cities. The Santa Ana winds tear at shingles in November. Thermal cycling, hot days followed by cool nights, fatigues asphalt year-round. In neighborhoods from Pasadena to Woodland Hills, we’ve seen what happens when a cheap installation meets a February rainstorm. That’s why we don’t send salespeople in trucks with out-of-state plates. We send background-checked, uniformed technicians who’ve trained as apprentices under our journeymen. Every job carries our written 90-Day Done Right Promise - if it’s not right, we come back and make it right, no paperwork, no arguing.
What Our Roof Replacement & Installation Service Includes
Full Roof Replacement
A full roof replacement means stripping every layer down to the deck, inspecting for hidden rot or structural damage, and building back with new underlayment, flashing, and surface materials. In Los Angeles, this is the right call when your existing roof is 25-plus years old, has multiple leak points, or was installed with now-obsolete materials we see in pre-1990s builds around Northridge and Santa Clarita. At Ridgeline Roofing Co., we photo-document the deck condition before we cover anything, and we never roof over old shingles - that’s a shortcut that traps heat and voids manufacturer warranties.

New Construction
New construction roofing is the installation of a complete system on a freshly built structure, where the roofline itself is being established for the first time. This demands precise coordination with framers and inspectors, especially in Los Angeles where Title 24 energy codes and fire-resistant material requirements in hillside zones like Thousand Oaks add complexity. We work from architectural plans, recommend the right material for the pitch and exposure, and handle permit pulls so your project stays on schedule.

Asphalt Shingles
Asphalt shingles remain the most common choice for Los Angeles homeowners because they balance cost, fire rating, and the architectural variety that fits everything from 1920s bungalows in Pasadena to tract homes in Palmdale. We install architectural and three-tab shingles from GAF and CertainTeed, with Class A fire ratings that satisfy local wildfire mitigation ordinances. In our experience, the difference between a 15-year shingle job and a 25-year one comes down to ventilation and nail placement - details we don’t leave to chance.

Metal Roofing
Metal roofing is steel, aluminum, or copper formed into panels or shingles that reflect heat, resist Santa Ana wind uplift, and carry 40- to 70-year lifespans. It’s ideal for Los Angeles homeowners who plan to stay put, especially in areas like Santa Ana or Woodland Hills where cooling costs and fire risk are both concerns. We install standing seam and metal shingle systems with concealed fasteners that eliminate the leak points common in through-fastened installations, and we size ventilation precisely to prevent condensation in our dry-summer, mild-winter climate.

Tile Roofing
Tile roofing, clay or concrete, is the signature look of Spanish and Mediterranean architecture across Los Angeles from Hancock Park to the hills above Burbank. Tile roofs last 50-plus years, but the underlayment beneath them typically fails in 20 to 25 years - a fact many homeowners don’t discover until water stains appear. We specialize in tile removal, underlayment replacement, and careful reinstallation or selective replacement of cracked tiles, working with Boral and other manufacturers to match color profiles that may be decades old.

Flat Roofing
Flat roofing serves low-slope additions, ADUs, and modern homes from Silver Lake to Venice where conventional pitched roofing isn’t practical. We install TPO, modified bitumen, and built-up systems with proper drainage design - critical in Los Angeles, where a flat roof without positive slope to scuppers or drains will pond water and fail within seasons. Our crews are trained in heat-welded seams and tapered insulation installs that correct structural sag without rebuilding the deck.

Brands We Service for Roof Replacement & Installation
We are authorized installers for seven leading manufacturers, and we stock or can source exact-match materials from each. For GAF, we’ve completed hundreds of Timberline HDZ and Ultra installations across Los Angeles County, and we maintain Master Elite certification standards in our flashing details and ventilation calculations. Our CertainTeed work spans Landmark Pro and Belmont shingle lines, with particular experience matching their color blends to HOA requirements in gated communities from Calabasas to Thousand Oaks. Owens Corning Duration and Oakridge products are our go-to for homeowners prioritizing wind resistance, and we’ve specified their SureNail technology on jobs from the coast to the Santa Clarita Valley where gust exposure is highest.
We also install Atlas, Tamko, and Boral systems regularly. Atlas StormMaster Slate and Pinnacle Pristine lines perform well in Los Angeles UV exposure. Tamko’s Heritage series offers solid value for investment properties and secondary structures. Boral’s clay and concrete tile catalog is unmatched for historical matching in neighborhoods like Pasadena and San Marino. Whether your existing roof is GAF, CertainTeed, Owens Corning, Atlas, Tamko, Boral, or another make entirely, we can assess it honestly, match it precisely, or recommend a better fit for your situation.
Signs You Need Roof Replacement & Installation Right Now
- Your roof is 20 years or older. Asphalt shingles in Los Angeles typically last 18 to 25 years depending on ventilation quality and sun exposure. Once you cross that threshold, granular loss accelerates, underlayment dries and cracks, and the next Santa Ana wind or heavy rain finds the weak points. We’ve replaced roofs in Northridge and Reseda where the homeowner didn’t realize the installation date was 1987.
- You’re finding granules in gutters or downspout outlets. Those granules are the UV-protective coating on your shingles. When they’re washing into your gutters, the asphalt beneath is baking bare. In Los Angeles south-facing exposures, we’ve seen this stage arrive in year 15. It’s not cosmetic - it’s the beginning of waterproofing failure.
- Daylight visible through the roof boards in your attic. This means gaps, cracks, or missing shingles that have progressed past the underlayment. It also means your attic ventilation and insulation are compromised, driving up cooling costs through Los Angeles summers. We document this with photos during our inspection and show you exactly where the breach is.
- Sagging areas or a wavy roofline. Sagging indicates structural compromise - rotted decking, failing rafters, or in older Los Angeles homes, termite damage that has gone undetected. This won’t be fixed with a patch. It requires deck replacement and often structural reinforcement before new roofing can be installed safely.
- Neighbors are replacing their roofs. In planned communities and tract developments across Santa Clarita, Palmdale, and Woodland Hills, homes were built in the same year with the same materials. If three houses on your street have new roofs, yours is the same age and has weathered the same conditions. Proactive replacement lets you schedule on your terms, not after an emergency leak.
Our Roof Replacement & Installation Process - Step by Step
- 1
Call and speak with a live person. When you call (844) 563-1816, day or night, a live Ridgeline Roofing Co. team member answers. We ask about your roof’s age, symptoms, and your schedule. No voicemail trees, no callback windows, no leaving you stranded after a storm has torn through the San Fernando Valley.
- 2
On-site photo inspection. Our background-checked, uniformed technician arrives at your Los Angeles home, climbs the roof, and documents everything with dated photographs - shingle condition, flashing integrity, ventilation setup, deck soundness, and any active leaks. We show you these photos and explain what we’re seeing in plain language, not scare tactics.
- 3
Upfront written estimate. You’ll receive a line-item estimate with material specifications, labor scope, and total cost. The number we quote is the number you pay. We don’t lowball to win the job and then find “surprises” once work begins. Our estimate includes the 5% senior and veteran discount if applicable, and we’ll apply our $50 off any repair over $250 if your project qualifies.
- 4
Scheduled installation with protective prep. We tarp landscaping, move patio furniture, and set up debris containment before the first shingle comes off. Our crews work efficiently - most replacements finish in one to three days - and we run magnets across the property daily to catch nails. In Los Angeles, where drought-stressed yards are fragile, we take this seriously.
- 5
Final walkthrough and 90-Day Done Right Promise. You inspect the finished roof with our lead technician. We verify clean gutters, intact paint, and proper ventilation function. Then we leave you with written warranty documentation, manufacturer registration, and our 90-Day Done Right Promise - if anything’s not right, we come back and make it right, no paperwork, no arguing.
How Much Does Roof Replacement & Installation Cost in Los Angeles?
A typical asphalt shingle roof replacement on a 2,000-square-foot Los Angeles home runs $12,000 to $18,000 including tear-off, deck repair up to two sheets, new underlayment, and GAF or CertainTeed architectural shingles. Tile roof replacement, including underlayment replacement and selective tile reinstallation, generally ranges $18,000 to $28,000 depending on tile type and roof complexity. Metal roofing starts around $20,000 for the same footprint and can reach $35,000 for standing seam copper or complex geometries. Flat roofing on additions or ADUs typically falls between $8,000 and $14,000 based on square footage and insulation requirements.
Several factors move these numbers. Roof pitch matters - steeper roofs in hillside Los Angeles neighborhoods like those above Glendale or in the Hollywood Hills require additional safety equipment and slower, more careful work. Deck condition is the biggest variable; we can’t price rot or structural repair until we see what’s beneath the old roofing, but we include reasonable deck allowances in our estimates and photograph any surprises before proceeding. Material choice swings cost significantly - Tamko Heritage shingles cost less than GAF Timberline Ultra HD, and Boral clay tile runs higher than concrete alternatives. Access issues, tight lots in older neighborhoods, and permit requirements in specific Los Angeles jurisdictions also affect timeline and pricing.
The best way to avoid overpaying is to get a detailed, written estimate that specifies manufacturer, product line, underlayment type, and warranty terms - not a single number on a business card. Our estimates are free, and we offer a free second opinion on any written estimate you’ve already received. Call (844) 563-1816 to schedule.

Frequently Asked Questions - Roof Replacement & Installation in Los Angeles
Roof replacement is the complete removal of your existing roofing materials down to the deck, inspection and repair of that deck, and installation of a new waterproofing system including underlayment, flashing, and surface materials. Installation refers to the same process on new construction or additions where no previous roof exists. At Ridgeline Roofing Co., we handle both, with the same photo documentation and upfront pricing for every job.
Most residential roof replacements in Los Angeles take one to three days from tear-off to final cleanup. Complex tile roofs, steep pitches in hillside neighborhoods, or jobs requiring extensive deck repair may extend to four or five days. We give you a specific timeline in your written estimate and don’t leave your home exposed overnight - temporary waterproofing goes up every evening if the job spans multiple days.
Asphalt shingle replacement typically runs $12,000-$18,000, tile $18,000-$28,000, metal $20,000-$35,000, and flat roofing $8,000-$14,000 for standard residential footprints. Exact cost depends on square footage, material choice, deck condition, and access difficulty. Call (844) 563-1816 for a free, no-obligation estimate with line-item pricing - the number we quote is the number you pay.

Every roof replacement carries our written 90-Day Done Right Promise - if anything about our workmanship is not right, we return and correct it with no paperwork, no arguing, and no charge. Manufacturer warranties vary by product line: GAF Golden Pledge offers 50 years on materials and 25 years on workmanship through certified contractors like Ridgeline Roofing Co.; CertainTeed and Owens Corning offer comparable tiers. We explain your specific warranty coverage before you sign, not after.
Move vehicles out of the driveway and garage to protect them from falling debris and give our delivery truck access. Remove or cover items in your attic, as vibration during tear-off can dislodge dust. Take down wall decorations, especially on the top floor, as hammering transmits through framing. We’ll handle patio furniture, landscaping protection, and daily magnetic nail cleanup. If you have a satellite dish or solar panels mounted on the roof, let us know when you call so we coordinate with your providers.
