Pomona Roof Pros provides professional commercial roofing in Pomona, CA for residential and commercial properties across the Pomona Valley. The commercial roofs we work on in Pomona are mostly small and old. Masonry storefronts downtown, two-storey mixed-use with apartments over retail, converted industrial along the rail corridor, light-industrial buildings out toward the Fairplex. Very few are simple rectangles with nothing on them.
Those buildings share a problem that has nothing to do with membrane selection. They are occupied by tenants on staggered leases, the roof is one continuous plane over several units, and nobody wants to fund a full replacement in a year when two suites are turning over. So the roof gets patched, unit by unit, complaint by complaint, and the patching eventually costs more than the roof.
The way out is a sectioned plan with real numbers in it. We divide the roof at expansion joints, firewalls or existing curb lines, give each section a remaining-life figure, and order them against the lease calendar and the actual risk. A landlord can then fund a third of the roof a year to a scope written once, instead of paying emergency rates every winter. The plan is a document, not a conversation.
The technical work is ordinary and has to be done properly. Two-ply SBS modified bitumen with a granulated cap sheet where there is heavy foot traffic and rooftop equipment. Mechanically fastened single-ply where the run is clean and the deck allows. A half-inch high-density cover board over any insulation. Tapered fill to give genuine slope to the drains rather than to the nearest low spot.
The details that actually leak on these buildings are parapets and equipment. Through-wall counterflashing instead of a bead of sealant at the coping. Curbs raised so a service technician can work without standing on the membrane. Walkway pads on the route to every unit. Clamping rings and strainers on drains somebody can actually clear. We label the drains and hand over a roof plan showing where each one goes.
We work around tenants because there is no alternative. Sections sequenced so no suite loses its ceiling, night and weekend tie-ins where the use demands it, and a written dry-in condition at the end of every day so an overnight storm does not become a claim against the building. None of this is exotic work. It is ordinary roofing done in an order that fits how the building earns money.
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 commercial roofing
The difference between commercial roofing that lasts and commercial roofing 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.

Why Pomona Chooses Pomona Roof Pros
- ✓Every slope gets its own remaining-life number in years, so you can decide what to fund and when.
- ✓We count layers and probe the deck before quoting, because a hidden third layer changes the entire price.
- ✓We argue against work. Coating aged shingles and reflashing a disused chimney both get talked out of here.
- ✓Staged reroofing across separate planes with their own drainage, never a vertical lap down one slope.
The standards behind commercial roofing
Quality here is not a matter of opinion — it is written down. The commercial roofing work we do in Pomona follows published industry standards: NRCA publishes the Roofing Manual, the industry's reference for details and slope minimums, and Asphalt Roofing Manufacturers Association sets the shingle application and ventilation guidance the warranties reference. If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
Every commercial roofing project in Pomona gets the same attention, whether it is a single room or a full commercial job. We show up on schedule, keep the site clean, and stand behind the work — the estimate is free and there is no pressure.
