Pomona Roof Pros provides professional asphalt shingle roofs in Pomona, CA for residential and commercial properties across the Pomona Valley. Asphalt is what most of Pomona is roofed with, and the first thing that matters is how many layers of it are up there. That single fact moves the price of the job more than the shingle you choose. Everything else follows from that count.
The code ceiling is two total layers of roof covering. A large share of the postwar tract houses in the flats have already been reroofed twice, and some sit at three where a permit was never pulled. Those are tear-off only, and the tear-off usually exposes 1x6 spaced sheathing that needs half-inch plywood before anything new goes down. That plywood is priced by the sheet, visibly, rather than buried in a lump sum.
Where an overlay is legal it is still not automatically right. Laying new shingles over a cupped slope telegraphs every ridge through the finish, adds weight to 2x4 rafters at 24 inches on center, and hides the deck condition for another twenty years. We quote overlays when the existing plane is flat and sound. We say so when it is a false economy. Usually it is.
On product, architectural laminated shingles are the default and three-tab is not worth the small saving. The laminate carries a thicker mat, a better wind rating, and it forgives the minor deck irregularity older framing always has. SBS polymer-modified shingles are the upgrade we genuinely recommend here, because modified asphalt stays flexible through the surface temperatures these slopes reach in August. The price gap between the two is smaller than most people expect.
The install details fail, not the shingle. Six nails inside the nailing zone. Synthetic underlayment run correctly at the laps. New drip edge at both eave and rake. W-metal or a closed-cut valley rather than a woven one. A kickout flashing anywhere a roof meets a wall above a gutter. That last detail is missing on most roofs we inspect, and it explains a great deal of the stained stucco below roof-to-wall junctions.
We check the product's CRRC listing against Title 24 before ordering, register the manufacturer's warranty in your name, and hand over the layer count and deck report in writing so the next owner is not guessing at what is under there. The permit and inspection record do the same job and cost you nothing extra.
Our licensed and insured team brings the right materials and equipment to every job — architectural laminated shingles with six-nail fastening, SBS polymer-modified asphalt shingles, 1x6 spaced sheathing overlaid with half-inch plywood, two-ply modified bitumen with a granulated cap sheet, salvaged mission and S-profile clay barrel tile, 24-gauge standing seam with concealed sliding clips — and backs the work with a written workmanship warranty. We serve Pomona and nearby communities including Claremont, La Verne, San Dimas, Diamond Bar.

Materials, equipment and how we do asphalt shingle roofs
The difference between asphalt shingle roofs that lasts and asphalt shingle roofs that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with architectural laminated shingles with six-nail fastening, SBS polymer-modified asphalt shingles, 1x6 spaced sheathing overlaid with half-inch plywood, two-ply modified bitumen with a granulated cap sheet, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Pomona job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in the Pomona Valley means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
