Gresham Roof Pros provides professional chimney flashing in Gresham, OR for residential and commercial properties across east Multnomah County. No part of a roof generates more leak calls than a chimney, and the cause is nearly always identical. Somebody sealed a joint instead of building one. It is the defect we photograph most often on a Gresham inspection. Caulk is not flashing.
Correct masonry chimney flashing arrives in two parts. Step pieces interleaved with the courses climbing each side, and counterflashing cut into a mortar joint above them and folded back down over the steps. The counterflashing is what protects the top edge, and it has to go into the masonry rather than onto it. Cut in, rather than stuck on, is the entire distinction.
What we normally find is one piece of aluminum surface-sealed to the brick with a bead of caulk. That holds for about three years. Then the sealant shrinks, the joint opens, water runs down behind the metal, and the stain shows up on a bedroom ceiling six feet away from the chimney. Chimney leaks almost never appear next to the chimney, which is exactly why they get misdiagnosed.
The upslope face needs a cricket on any chimney wider than roughly thirty inches. Lacking one, the upslope face becomes a dam sitting across the slope, gathering water and debris, and on this side of the metro it also collects the ice that forms during a freezing-rain night and sits there until the thaw. A cricket is sheet metal and an hour of labor, and it removes a recurring problem permanently.
Masonry matters as much as metal does. A cracked crown, spalled brick or an open joint near the top lets water into the stack itself, and it emerges lower down looking precisely like a flashing leak. The crown and the uppermost brick courses get examined closely before we quote flashing at all. Repointing a crown is masonry work and we will bring a mason rather than fake it.
If your chimney is disused, already capped, and the fireplace has not been lit in a decade, taking it down below the roofline and framing the deck over is often cheaper than restoring the masonry and flashing it properly. We will price both and let you decide with real numbers in front of you. Plenty of houses here are carrying a chimney nobody has lit since the eighties.
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 chimney flashing
The difference between chimney flashing that lasts and chimney flashing 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.
