Roofing Options for Every Style & Budget
Shingles
Asphalt Shingles
Asphalt shingles are what most Colton houses wear, because they cost less, go on faster and repair easily. Installed by an experienced roofer on a residential roof, they handle sun, wind and the occasional hard rain without complaint.
Fiberglass Shingles
Fiberglass shingles use a glass-fiber mat under the asphalt, which cuts the weight and carries the fire rating. They are a sensible pick when the roof needs a Class A assembly and the budget is fixed.
Dimensional Shingles
Dimensional shingles are laminated, which gives the roof depth and shadow lines from the curb and adds years to the life of the covering. On a house with steep pitches and visible roof planes, the difference shows.
Tile
Clay Tiles
Clay tile is fired, so the color runs through the tile and does not wash out under Inland Empire sun. It is a heavy covering that needs framing built for it, and on the right house it outlasts everything else on the roof.
Concrete Tiles
Concrete tile gives you the weight and the life of clay in a wider range of profiles and colors. It is the standard covering across much of Colton’s tract housing, and individual broken tiles can be swapped without touching the rest of the field.
Lightweight Tiles
Lightweight tile was made for houses that want a tile roof without the structural work. It is a good answer on an older home where adding several thousand pounds to the framing is not something you want to pay an engineer to sign off.

Roof Repairs in Colton, CA
When water comes through a Colton ceiling, the source is usually a failed flashing detail or a boot that has gone brittle in the sun, and it is rarely directly overhead. Alpha & Omega Roofing has repaired roofs for more than six decades, and your roofer traces the leak to where the water is entering before opening anything up. We replace the material that has failed, rebuild the detail properly and photograph the work. You are told what caused the leak and how much life the rest of the roof has, so the next decision is yours to make with real information.
Re-Roofing in Colton, CA
A full replacement is the right call once underlayment has given out across the roof rather than in one corner. a complete roof replacement from Alpha & Omega Roofing begins with a tear-off to the bare decking so the sheathing can be inspected and repaired. From there we run new underlayment, set new flashing at the valleys, sidewalls, chimneys and pipe jacks, and lay the covering you selected. Your Colton roofers finish the job with the site cleaned and the permit ready for its final, which matters as much as the roof itself when you go to sell.
Roof Maintenance in Colton, CA
Roof maintenance in Colton is mostly about staying ahead of sun damage and wind. Our maintenance service puts eyes on your roof each year, so a cracked tile or a lifted shingle course gets replaced while it is still a cheap fix. We clear the valleys, check the pipe boots, and look at every place where the roof meets a wall, because those transitions leak first. An annual agreement keeps this on a schedule instead of leaving it to whichever week you happen to remember, and it lets you plan the eventual replacement rather than react to it.
Roof Inspections in Colton, CA
An inspection is the cheapest information you can buy about a roof. Your Colton roofing contractor walks the surface and then looks at the underside from the attic, photographing underlayment, flashing, valleys and any penetration that has been disturbed. Buyers use the report during escrow, insurers ask for the photographs at renewal, and owners use it to decide whether to repair or replace. The report sets out the roof’s present condition and roughly how many years it has left.
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 Colton Homeowners Should Know Before a Reroof
Roofing permits in Colton are issued by the Building Division of the Development Services Department at 659 North La Cadena Drive, and the counter handles both the application and the inspection scheduling.
Colton amended the state roof covering table rather than adopting it as written. Colton Municipal Code Section 15.06.200 rewrites California Building Code Table 1505.1 so the classification applies to new buildings, re-roofs and additions alike, with Class A required across most construction types and a footnote sending Very-High Fire Hazard Zone work to Section 1505.1.1 for Class A. The City’s own reroof handout adds the part that catches people out: a tear-off gets two inspections, the first on the bare roof sheathing after the old material is off and before any new material goes down. Miss that window and the roof comes back open. A signed CF1R reroofing compliance form has to be in the packet at submittal, not afterwards.
Colton’s housing stock is split between mid-century and the 1980s. Census figures for 2020 to 2024 give a median year built of 1979, with 51.4 percent of the city’s 17,856 units built before 1980 and 1,431 of them standing since before 1940.
Colton is in California Building Climate Zone 10 under Title 24, which decides the aged solar reflectance and thermal emittance values a re-roof has to hit. The line is not far away: most of San Bernardino next door is Zone 10 as well, but its 92404 ZIP code is listed in Zone 16, where different values apply.
