Gresham Roof Pros provides professional roof leak repair in Gresham, OR for residential and commercial properties across east Multnomah County. Ask a Gresham homeowner when the ceiling stain appeared and the honest answer is rarely during ordinary rain. It turns up on the two or three nights each winter when the wind is roaring out of the gorge. The rain is the same rain. The pressure behind it is not.
Rain falling straight down is an easy load for a shingle roof. Rain traveling sideways at forty miles an hour is a different thing entirely. It gets driven up under the butt edge, past the head lap, in through ventilation openings, and around any penetration whose flashing was sized for gravity and nothing else. Pressure differences across a roof plane will move water uphill for several inches, which is more than most head laps allow for.
So a leak hunt here starts on the east elevation and works west, which is the reverse of how most crews walk a house. We look first at east-facing rakes, east gable louvers, the windward side of every plumbing vent, and the upslope corner of any chimney or dormer sitting on that half of the roof. It sounds fussy until you find the third house in a row leaking at the same corner.
Water testing follows the same logic. A hose held straight down over a suspect area proves very little in this climate. We spray uphill at low pressure, one small zone at a time, with somebody in the attic holding a light, and each zone runs long enough to be a fair test before anyone moves the hose. Rushing the test is how a leak gets declared fixed twice and comes back in November.
Most of what we find is unglamorous. A lifted tab whose sealant strip never bonded. A nail backed out of the sheathing. A cracked pipe boot. Counterflashing laid on top of brick instead of cut into a mortar joint. A closed-cut valley now packed with debris and holding water against the cut edge for days after a storm. None of these cost much to put right, and all of them are cheaper found in October than in February.
Repairs get written down: the location, the cause as we actually found it, the materials used, and a straight read on how much life the surrounding roof has left. If one slope shows three separate failures we say so, because past that point patching is just paying for the same roof twice. We would rather quote the replacement beside the repair and let you compare two real numbers.
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 leak repair
The difference between roof leak repair that lasts and roof leak repair 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.
