Roofing Service in Costa Mesa

Alpha & Omega Roofing has worked on Costa Mesa roofs since 1960. The company is locally owned and locally operated, and every crew is licensed, bonded and insured. Most of the housing here went up between 1950 and 1979, so a Costa Mesa job usually means working over older sheathing and older framing, and your roofer should confirm what sits under the covering before the tear-off starts. We repair, maintain, inspect and replace roofs on single-family homes, condominiums, apartment buildings and commercial properties across the city. Your estimate lists what we found, what we recommend and what each option costs, so you can decide with the numbers in front of you. We also serve nearby Newport Beach and Huntington Beach.

Residential Roofing Services

Trusted Across Southern California Since 1960

Alpha & Omega roofs houses in Costa Mesa, and the same company has worked for large institutions elsewhere in Southern California. Those jobs run on posted schedules, safety paperwork and staged inspections, and the same habits travel to a house on a residential street. What changes between a campus building and a three-bedroom home is the logistics, not the standard of the work.

Roof Repairs in Costa Mesa, CA

Rain finds the weak point first, and by the time you see a stain on a ceiling or a drip at a light fixture, the water has been traveling for a while. Our roofers trace a leak back to its source instead of patching the spot where it shows, because water runs along rafters and sheathing before it drops. Repairs cover flashing at walls and chimneys, valley metal, pipe collars, ridge and hip work, slipped or cracked tile, and torn or missing shingles. Rotted sheathing gets replaced rather than covered over. You receive photographs of the damage and of the finished repair, which helps if you later file a claim or sell the house.

Re-Roofing in Costa Mesa, CA

When repairs stop being worth the money, a full roof replacement resets the clock on your house. We strip the old covering down to the wood deck, replace sheathing that has softened, and rebuild edge metal, valleys and flashing before the new system goes on. Underlayment, fasteners and ventilation are specified to match the assembly you choose, so the warranty the manufacturer registers describes what is actually on your roof. Debris is contained as it comes off, and the driveway and landscaping are protected while the crew works. Before the first day you will know which materials are going on, how long the job should take, and what happens if we open the deck and find damage underneath.

Roof Inspections in Costa Mesa, CA

An inspection is worth booking before you buy a house, before an insurance renewal, and after a winter that brought heavy rain. Our roofers walk the roof where it is safe to do so, check the attic side for daylight and moisture, and record the condition of flashing, penetrations, drainage and the covering itself. You get a written report with photographs, an estimate of the serviceable life left in the roof, and a split between what should be handled now and what can wait. Carriers and buyers ask for that documentation, and having it already in hand keeps a renewal or a sale from stalling.

Roof Maintenance in Costa Mesa, CA

Maintenance is the cheap part of owning a roof. Debris sitting in a valley, a loose pipe collar or one cracked tile costs very little to put right and a great deal to ignore for three years. Our maintenance visits clear the drainage paths, reseal exposed fasteners, check the flashing joints and swap out the small components that fail first. We keep a record of every visit, so you can see how your roof is changing rather than guessing at it. Annual agreements cover the scheduled visits and a written condition report each time, which also builds the history a carrier will ask for.

License and Manufacturer Certifications

We hold current manufacturer certifications with GAF, Malarkey, Owens Corning, CertainTeed, Versico, FiberTite, and DOW, covering steep-slope shingle and tile work as well as single-ply commercial systems. Those certifications let us register manufacturer-backed warranties of up to 20 years on material and workmanship. We carry workers’ compensation and liability insurance, and our customer reviews are published on the site.

We specify cool-roof rated products that meet the Title 24 aged solar reflectance and thermal emittance values, from the manufacturer lines we are certified to install.

What Costa Mesa Homeowners Should Know Before a Reroof

Costa Mesa issues roofing permits through the Building Safety Division of the Community Development Department, on the second floor at 77 Fair Drive. Your contractor pulls the permit before the tear-off begins, and the permit stays open until the City has inspected the finished work and signed it off.

The part that catches Costa Mesa homeowners out is the waste side of the job. Under Chapter 4 of Title 8 of the Costa Mesa Municipal Code, construction and demolition projects have to divert 65 percent of the waste they generate away from the landfill, and the City applies that to the whole building permit rather than to a demolition line item. If your roofer self-hauls the tear-off, weight tickets and a signed reporting form have to reach the City before the final building inspection, and each ticket has to state that the material came from Costa Mesa and was processed as construction and demolition debris. Tickets showing municipal solid waste are not accepted. Where a franchise hauler is used instead, the bin has to stay on site for the length of the project.

Costa Mesa is an older housing market than its newer commercial corridors suggest. Census figures for 2020 to 2024 put the median year built at 1972, with 26.0 percent of units dating from the 1960s and 68.3 percent built before 1980. Roofs on houses from that period often sit on skip sheathing or thin plywood, so what the crew finds once the covering is off can change the scope of the work.

Costa Mesa ZIP codes 92626 and 92627 both sit in California Building Climate Zone 6 under Title 24. The Santa Ana ZIP codes immediately inland, 92704 and 92707, are Zone 8, so cool-roof values are not interchangeable across that line.

Roofing Options for Every Style & Budget

Shingles

Dimensional Shingles

Dimensional shingles are built up in layers, so the surface reads like shake or slate from the street. They weigh more than a three-tab shingle and last longer, and the shadow lines hide minor deck irregularities on an older Costa Mesa house. Most homeowners choose them when they want the look of a heavier material without the framing work that comes with it.

Asphalt Shingles

Asphalt shingles are the lowest-cost way to put a warrantied roof on a house, and they go down quickly, which keeps your home open to the weather for less time. The color range is wide, replacement pieces are easy to source, and a torn shingle after a storm is a short repair rather than a project.

Fiberglass Shingles

Fiberglass shingles use a glass-fiber mat in place of an organic one, which makes them lighter and gives them a stronger fire rating. They are a practical covering for residential roofs on older framing, where every pound saved on the covering is a pound the rafters never have to carry.

Tile

Concrete Tiles

Concrete tile is heavy, long-lived and holds its shape in sun and salt air. On a Costa Mesa house built for a lighter covering, the framing has to be checked before it goes on. Where the structure supports it, concrete tile is one of the longest-lasting roofs you can buy.

Clay Tiles

Clay tile keeps its color because the color is fired into the body rather than applied to the surface. It suits the Spanish and Mediterranean elevations common on this side of the county, and individual tiles can be lifted and replaced without disturbing the run around them.

Lightweight Tiles

Lightweight tile gives you the profile of a traditional tile roof at a fraction of the load, which matters on a house framed in the 1950s or 1960s. It is the usual answer when a homeowner wants tile on a structure that was never engineered to carry it.
