Gresham Roof Pros provides professional roof coatings & sealing in Gresham, OR for residential and commercial properties across east Multnomah County. We turn down more coating work than we accept. A coating is a genuinely good product inside a narrow set of circumstances, and most of the roofs people ask us to coat in Gresham fall well outside it. Saying no here has cost us jobs and we keep saying it.
Start with what a coating cannot do. It is a thin liquid-applied film. It does not replace wet insulation, it does not close a seam that has separated, and it adds no structure whatsoever. Rolled over a saturated assembly it seals the water in and buys you roughly one season before the same call comes back. The water is still in there and it is still doing what water does.
We will not coat asphalt shingles at all. Moisture gets trapped in the mat, the state of the sealant strip is hidden, any remaining material warranty ends, and makes the eventual tear-off slower and dearer. If a shingle roof is bad enough that coating sounds attractive, what it needs is replacing. There is no version of this where a coated shingle roof ends well. We have removed a couple and the tear-off took twice the labor.
The application window in this basin is genuinely tight. Acrylics need surface temperature above the manufacturer's minimum, no dew sitting on the deck, and a run of dry days to cure through. Realistically that means July into the middle of September, because nearly all of the year's rain falls outside those weeks. Coating outside that window is the most common reason a coating fails early.
It also means we do not coat during east-wind season, which is exactly when people ask for it. A cold, dry gorge wind feels like perfect drying weather and is not. Surface temperatures sit under the minimum, the dew point swings hard overnight, and the film skins over before it has cured underneath. People hear dry and assume cured, and those are two entirely different states.
Where coating does work it works well. A sound single-ply or modified bitumen roof with dry insulation, working drains and a few years left that you want extended is a good candidate. So is a metal roof with solid panels and weeping fasteners, where a fabric-reinforced seam and fastener treatment is real value. On the right roof a coating buys years for a fraction of a re-cover, which is why the product stays on the truck.
Our licensed and insured team brings the right materials and equipment to every job — ASTM D7158 wind class printed on the shingle wrapper, six-nail fastening inside the printed nail zone, starter strip with factory adhesive carried up the rake, hand-sealed first courses set in asphalt roof cement, externally baffled ridge vent with a weather filter, synthetic underlayment cap-nailed against wind lift — and backs the work with a written workmanship warranty. We serve Gresham and nearby communities including Troutdale, Fairview, Wood Village, Corbett.

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 ASTM D7158 wind class printed on the shingle wrapper, six-nail fastening inside the printed nail zone, starter strip with factory adhesive carried up the rake, hand-sealed first courses set in asphalt roof cement, 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 Gresham 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 east Multnomah County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
