Roofing Service in Mission Viejo
Alpha & Omega Roofing has been roofing Southern California properties since 1960, and Mission Viejo is part of our south Orange County service area. We are locally owned and locally operated, licensed, bonded and insured. Mission Viejo was built as a master-planned community in the 1970s and 1980s, so much of the work here is on concrete tile roofs where the tile is still good and the underlayment beneath it has reached the end of its life. We also serve nearby Laguna Niguel and Laguna Woods.

Roofing Options for Every Style & Budget
Tile
Concrete Tiles
Concrete tile covers a large share of Mission Viejo. It is long-lived, and on most of these houses the tile can be lifted, stacked and relaid over new underlayment rather than replaced.
Clay Tiles
Clay tile is fired, so the color is part of the tile and does not fade. It carries a Class A fire rating, which matters in the parts of the city now mapped as fire hazard zones.
Lightweight Tiles
Lightweight tile keeps the tile look while reducing the load on the framing, which makes it a good replacement when broken original tile is no longer available.
Shingles
Dimensional Shingles
Dimensional shingles are laminated in layers, which gives a roof depth and shadow from the street and longer manufacturer coverage than a three-tab.
Fiberglass Shingles
Fiberglass shingles are built on a glass mat, keeping them light and fire-resistant. Class A shingle assemblies are a practical choice for residential roofing in fire hazard zones.
Asphalt Shingles
Asphalt shingles are the most economical way to cover a roof properly. They install quickly and repair easily, and they come in colors that fit most HOA palettes.
License and Manufacturer Certifications
Alpha & Omega Roofing, Inc. holds California contractor license #C39-857106. 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 Mission Viejo Homeowners Should Know Before a Reroof
Mission Viejo issues re-roof permits through the Building Services Division of the Community Development Department at City Hall, 200 Civic Center. Since 2023 the City has taken permit applications and plans online only, through its Client Self Service portal, rather than at the counter. Many neighborhoods also have an HOA with its own roof material and color standards, so that approval is worth getting before the permit application.
Two Mission Viejo rules affect a re-roof. The first is construction waste: the City’s diversion program, adopted in Ordinance No. 04-225, requires 75 percent of construction and demolition debris to be kept out of the landfill. Under Municipal Code Section 6.10.1110, a lift-and-relay of an existing tile roof is exempt from the deposit and falls back to the 65 percent CALGreen minimum. A full tear-off is not, so the scope of the job changes the paperwork. The second is fire: on May 27, 2025 the City Council adopted CAL FIRE’s updated Fire Hazard Severity Zone maps, which added Very High and High zones inside the city. In those zones the Class A roof requirements of Building Code Chapter 7A apply, and the City’s map shows whether your address is affected.
Mission Viejo’s housing came in two waves. Census figures for 2020 to 2024 give a median year built of 1979 across 34,285 housing units, with 39.0 percent built in the 1970s and 24.9 percent in the 1980s. That puts most roofs here at forty to fifty years old, which is about when the original underlayment under concrete tile gives out.
Mission Viejo’s residential ZIP codes, 92691 and 92692, are in California Building Climate Zone 8 under the Energy Commission’s ZIP code table. Laguna Niguel and Laguna Hills, toward the coast, are Zone 6, so cool-roof values change as you move west.
Trusted Across Southern California Since 1960
We roof houses across south Orange County, and our crews have also worked on institutional buildings elsewhere in Southern California. Those clients hired us for the reason homeowners do: the detail work holds and the crew finishes on the date it gave. A single-family tile relay gets the same crews and the same license as a large contract.

Roof Maintenance in Mission Viejo, CA
On a Mission Viejo tile roof, the tile usually outlasts what is under it. Our maintenance service puts a roofer up there on a schedule to replace cracked or slipped tile, renew pipe boots, clear valleys and check the flashing where tile meets walls. Every visit is photographed, so you can see the roof change and plan the underlayment replacement on your own schedule.
Roof Repairs in Mission Viejo, CA
Water can run a long way under tile before it reaches a ceiling, so the stain is rarely under the failure. Alpha & Omega Roofing has spent more than six decades finding the actual entry point. On Mission Viejo houses that is usually a failed underlayment lap, a cracked tile, a hardened pipe boot or a short-lapped wall flashing. We lift the tile, repair what the water reached, rebuild the detail and photograph it before the tile goes back.
Roof Inspections in Mission Viejo, CA
An inspection is the cheapest way to learn how much life your roof has left, whether you are buying, renewing a policy, or deciding between a relay and a replacement. Your roofer walks the surface, checks the attic and photographs underlayment, flashing, valleys and penetrations.
Re-Roofing in Mission Viejo, CA
Most Mission Viejo tile roofs need new underlayment, not new tile. A full roof replacement from Alpha & Omega Roofing lifts and stacks the sound tile, strips the old underlayment to the deck, repairs any soft sheathing, then installs new underlayment and flashing before relaying. In a fire hazard zone we build to Class A. The permit is closed out properly at the end.
