Roofing Service in Orange
Alpha & Omega Roofing has been roofing Southern California properties since 1960, and the City of Orange is now part of our Orange County service area. We are locally owned and locally operated, licensed, bonded and insured. Orange has more variety than most cities in the county: craftsman bungalows and Victorians in Old Towne, 1960s tracts across the middle of the city, and newer homes in the eastern hills. Each of those needs a different approach, and we start every job by finding out which rules apply to your address. We also serve nearby Anaheim and Yorba Linda.

Roofing Options for Every Style & Budget
Tile
Clay Tiles
Clay tile is fired, so the color is part of the tile and does not fade. It carries a Class A rating and suits the Spanish and Mission style houses found across Orange.
Concrete Tiles
Concrete tile is dense and long-lived and comes in flat and profiled shapes. Broken pieces are replaced one at a time, so a repair does not mean a new roof.
Lightweight Tiles
Lightweight tile gives an older house the look of tile without overloading framing that was built for shingles.
Shingles
Dimensional Shingles
Dimensional shingles are laminated in layers for depth and shadow, and many lines are Class A rated, which Orange requires on every roof.
Asphalt Shingles
Asphalt shingles are the most economical full replacement. A Class A rated asphalt shingle installed to the manufacturer’s instructions meets the City’s fire rule and holds up to inland heat.
Fiberglass Shingles
Fiberglass shingles are built on a glass mat, which is what gives most of them their Class A fire rating. They are a practical choice for residential roofs across the city.
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 Orange Homeowners Should Know Before a Reroof
The City of Orange issues building permits through Building and Safety Services in the Community Development Department at 300 East Chapman Avenue. Applications are filed through the City’s online Civic Portal, and the counter is open on weekdays.
Orange is stricter than most nearby cities about roof fire ratings. Orange Municipal Code Section 15.36.030 requires every roof covering, on new and existing buildings, to be a fire-retardant, UL-listed Class A assembly, and it does not allow a new covering to be installed over an existing wood shake or shingle roof. The City replaced its fire hazard zone map in 2025 with Ordinance O-7-25, which adopted CAL FIRE’s Fire Hazard Severity Zones for the eastern hills. If the house is in the Old Towne Historic District, exterior changes including roofing are reviewed under Chapter 17.17 against the Historic Preservation Design Standards for Old Towne, by staff for small changes and by the Design Review Committee for larger ones. Construction noise is allowed from 7:00 a.m. to 8:00 p.m. Monday through Saturday and from 9:00 a.m. to 8:00 p.m. on Sundays and federal holidays under Section 8.24.050(E), and Chapter 8.31 requires covered projects to divert at least 65 percent of their debris.
Orange’s housing covers a wide span of years. Census figures for 2020 to 2024 give a median year built of 1973 across 46,952 housing units, with 25.3 percent built in the 1960s, 19.3 percent in the 1970s and 64.3 percent standing before 1980. Another 4.6 percent were built in 1939 or earlier, most of them in and around Old Towne, where the roof is part of the historic fabric.
Every Orange ZIP code, 92865 through 92869, falls in California Building Climate Zone 8 under the Energy Commission’s ZIP code table, so the same cool-roof values apply across the city.
Trusted Across Southern California Since 1960
We roof houses across Orange, from Old Towne to the eastern hills, 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 re-roof gets the same crews and the same license as a large contract.

Roof Maintenance in Orange, CA
Sun and Santa Ana winds wear an Orange roof faster than rain does. Our maintenance service puts a roofer on the roof on a schedule to replace cracked tile, re-secure lifted shingles, renew pipe boots and clear valleys and gutters. Every visit is photographed, so you can see the roof age and plan its replacement on your own timeline.
Roof Repairs in Orange, CA
Water often travels a long way before it shows up on a ceiling, so the stain is rarely under the leak. Alpha & Omega Roofing has spent more than six decades tracing leaks to where they start. On Orange houses that is usually a failed vent boot, a slipped tile, a worn valley or old flashing at a chimney or wall. We open the area, replace what got wet, rebuild the detail and photograph it.
Roof Inspections in Orange, CA
An inspection tells you how much life the roof has left before you buy, sell or renew insurance. In Orange it also confirms whether the existing covering is a Class A assembly, which matters if you plan to repair rather than replace. Your roofer walks the surface, checks the attic and photographs everything.
Re-Roofing in Orange, CA
A full roof replacement in Orange is built around the City’s Class A rule. Alpha & Omega Roofing strips the roof to the deck, removes any old shake rather than covering it, repairs soft sheathing, and installs new underlayment, flashing and a Class A covering. In Old Towne we get design approval first. The permit is closed out properly at the end.
