Roofing Service in Sierra Madre
Alpha & Omega Roofing has worked on Sierra Madre houses since 1960, and the town has a particular set of conditions that shapes every quote we write here. Lots run uphill, roof pitches are steep, mature trees overhang the eaves, and the whole city is covered by a fire-retardant roofing requirement. We are locally owned and locally operated, licensed, bonded, and insured, and we hold the manufacturer certifications for the products that meet that requirement. We also serve nearby Pasadena and Altadena.

Roofing Options for Every Style & Budget
Shingles
Fiberglass Shingles
Fiberglass shingles are built on a glass mat instead of organic felt, which lowers the weight and raises the fire rating. That second point does real work in Sierra Madre, where the covering has to be fire-retardant by ordinance. They also stay flat through a hot summer rather than curling at the edges.
Dimensional Shingles
Dimensional shingles are laminated, so the roof carries shadow and depth rather than reading as a flat sheet. On the steep pitches common here that texture is visible from the street below and does a lot for the look of the house. They weigh more than three-tab and carry longer manufacturer coverage.
Asphalt Shingles
Asphalt shingles remain the most affordable warranted covering available, and Class A rated asphalt systems are made by every manufacturer we install. Nailed to the manufacturer schedule with the correct starter and ridge, the roof runs for decades. The class rating is a property of the tested assembly, so the underlayment matters as much as the shingle.
Tile
Concrete Tiles
Concrete tile is dense, wind-resistant, and rated Class A as an assembly, which suits a town with a fire-retardant roofing ordinance. Profiles run from flat to high-barrel, and individual tiles are replaceable, so a branch through the roof stays a repair. The framing has to carry the weight, and we confirm that before quoting a change.
Clay Tiles
Clay tile is fired through, so its color is permanent and a chipped edge shows the same shade as the face. On the Craftsman and Spanish houses around the village it sits comfortably, and Alpha & Omega Roofing installs it over the underlayment the listing requires, since the underlayment is what carries the water and the rating.
Lightweight Tiles
Lightweight tile delivers the profile of clay or concrete at a fraction of the load, which makes tile realistic on residential roofs framed decades ago for shake or composition. On a steep Sierra Madre lot the reduced weight also makes the material easier to move and set, which shortens the job.

Roof Inspections in Sierra Madre, CA
An inspection here answers two questions at once: how much service is left in your roof, and whether what is on it still satisfies the fire-retardant rule. We photograph the covering, the flashing, the valleys, and the condition of the eaves and vents, then write up what needs work now and what can wait. If your roof is sound, the report gives you a horizon you can plan against.
Roof Maintenance in Sierra Madre, CA
A roof under oak and sycamore needs clearing more often than a roof on open ground. Leaf litter dams the valleys, fills the gutters, and holds moisture against the covering long after the rain stops, and on a fire-rated roof that debris is also fuel sitting on the assembly you paid for. Our maintenance agreements in Sierra Madre schedule the clearing, check and renew the sealant at every penetration, reseat what has moved, and leave you a written record.
Roof Repairs in Sierra Madre, CA
Steep roofs on hillside lots fail at the transitions. The trouble spots are a valley carrying runoff from two large planes, the flashing where a lower roof ties into an upper wall, a skylight curb, and a vent collar split by the sun. Our roofers work back from the stain inside to the actual entry point, which on a pitch this steep can be a considerable distance uphill. Repairs go in with material matched to the existing roof and to the same fire classification, so a patch does not quietly downgrade the assembly.
Re-Roofing in Sierra Madre, CA
Sierra Madre is where a full roof replacement earns its money, because the fire rating of the assembly is only as good as the way it was installed. We tear off to the deck, replace boards that have softened, and rebuild underlayment, flashing, and edge metal before the covering goes back on. Older houses framed for wood shake need a solid deck added, and we price that at the estimate rather than mid-job. The material is installed to the manufacturer listing so the class rating and the warranty both stand.
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 Sierra Madre Homeowners Should Know Before a Reroof
Sierra Madre issues its own permits. The Building and Safety Division is at 232 W. Sierra Madre Blvd., Sierra Madre, CA 91024, and the service counter is open Monday through Thursday, 7:30 a.m. to 5:30 p.m., closed Fridays and holidays. The Building Official holds appointments on Tuesday and Wednesday mornings, which is worth knowing if your job needs a conversation rather than a counter transaction.
The roofing rule here is citywide and it is old. Sierra Madre Municipal Code Section 15.28.010 states that roof coverings for all structures within the city shall be fire-retardant, and it defines fire-retardant as any covering meeting the Underwriters Laboratories specification for a Class A roof covering, with an exception for asphalt composition shingles carrying a Class B rating. There is a narrow allowance for additions of 25 percent or less of the square footage over the life of the building to match the existing material, at the fire marshal discretion. Section 15.28.020 separately designates a very high fire hazard severity zone in Sierra Madre on a map dated June 24, 2008 and held by the City Clerk. In practice that rules out wood shake, and the class rating belongs on your estimate.
The housing stock is largely mid-century with an older core. Census figures for 2020–2024 give a median year built of 1959, with 17.6 percent of units dating from 1939 or earlier, 21.5 percent from the 1950s, 18.2 percent from the 1960s, and 79.8 percent standing before 1980. Houses of that age were frequently framed for wood shake, so the decking is the first thing we look at.
Sierra Madre falls in California Building Climate Zone 9 under Title 24, and so do Pasadena and Altadena, so the cool-roof values apply consistently across this part of the foothills. Where the ground rises further west the picture changes, with the Sunland and Tujunga ZIP codes, 91040 and 91042, placed in Zone 16.
