Pomona Roof Pros provides professional roof coatings & sealing in Pomona, CA for residential and commercial properties across the Pomona Valley. We sell coatings and we turn down most of the requests we get for them. The common ask in Pomona is a coating over an aged asphalt shingle roof, and that is the one job where the money is almost always wasted. We explain why rather than simply decline.
Here is the reasoning. A shingle roof sheds water because the courses overlap, not because the surface is sealed. When it fails, it fails at the laps, the fasteners and the flashings. A film of elastomeric acrylic over the top restores none of those, and it does bridge the tabs so the roof can no longer lie flat or dry out. It also ends the manufacturer's warranty and makes the eventual tear-off dirtier and dearer.
What a coating genuinely does is extend a sound low-slope membrane or a metal roof. On a modified bitumen cap sheet that is dry underneath, embrittled on the surface and still well adhered, an acrylic or silicone system adds real years and drops surface temperature. On a metal roof with sound panels and failing exposed fasteners, a fabric-reinforced system over rewashered screws is a legitimate alternative to replacement. Both of those are jobs we take.
The test is moisture, never appearance. We probe the assembly and read it with a meter at the low points and around every penetration. If there is trapped water in the felts or the insulation, coating seals it in, and a deck rots faster under a new membrane than it ever did under a leaking one. A leaking roof at least dries between storms; a sealed wet one never does.
Where a coating is right, preparation is most of the cost. Wash, prime where the substrate demands it, detail every seam, penetration and termination with reinforcing fabric first, then apply the field coats at the manufacturer's wet mil rate measured with a gauge rather than judged by eye. A thin coat is a two-year coat. We record pails opened per square so the thickness is verifiable afterwards.
Sealing has one other honest use, which is buying time on purpose. If your reroof is eighteen months out, we will detail the failing points, leave the field alone, and price it as a bridge rather than as a roof. Priced in hundreds rather than thousands, with an end date on it.
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 roof coatings & sealing
The difference between roof coatings & sealing that lasts and roof coatings & sealing 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.
