Aloha Roof Pros provides professional chimney flashing in Aloha, OR for residential and commercial properties across the Tualatin Valley. Most of what gets called a chimney in Aloha is not masonry at all. It is a framed chase finished in siding with a factory-built metal flue running up the middle, which was the standard fireplace of the era this housing was built in.
That distinction reshapes the entire repair. A masonry stack takes step flashing interleaved with the courses and two-piece counterflashing cut into a mortar joint. A framed chase takes step flashing along the sides, a headwall detail across the back, and a metal chase cover on top with a storm collar sealing where the flue passes through it. Kickout flashing at the base of the sidewall run is the piece most often missing entirely.
Chase covers are where these assemblies fail. The original was usually thin galvanized sheet with a flat top, and after four decades it has rusted through, developed a low spot that holds standing water, or lost its seal at the collar. Water then runs down the outside of the flue and appears on a ceiling nowhere near the fireplace. Siding on the chase usually has to come off partway to do this properly.
We replace those with a sloped stainless or heavy-gauge cover carrying a proper drip edge and a cross break so nothing can pond on it, and we reseal the collar using high-temperature material rather than the ordinary sealant that failed the first time around. The flue itself gets inspected while we are up there, since a rusted outer pipe is a different problem.
Up on the plane itself, any chase or stack wider than roughly thirty inches gets a framed saddle built on its uphill face so that runoff divides and passes down either side instead of piling behind the back wall. A surprising number of houses around here never received one from the builder. Cap and spark arrestor go back on afterward, and we photograph the finished assembly because nobody else will climb up.
Genuine masonry chimneys do exist in the older pockets of this area, and we flash those the traditional way, with counterflashing let into the joint and no dependence on caulk to keep water outside. Where a previous repair relied on sealant, we remove it rather than adding another bead. Sizing the saddle correctly matters, since one built too shallow simply moves the ponding a foot uphill instead of getting rid of it.
Our licensed and insured team brings the right materials and equipment to every job — metal connector plates read tooth by tooth from the attic floor, the clear opening of a little over twenty-two inches between chords, a stamped repair detail drawn by an engineer for an altered chord, tubular daylight devices threaded between web members, self-adhered membrane at valleys and every roof penetration, gable end frames that carry no triangulated webbing — and backs the work with a written workmanship warranty. We serve Aloha and nearby communities including Beaverton, Hillsboro, Cedar Hills, West Slope.

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 metal connector plates read tooth by tooth from the attic floor, the clear opening of a little over twenty-two inches between chords, a stamped repair detail drawn by an engineer for an altered chord, tubular daylight devices threaded between web members, 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 Aloha 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 Tualatin Valley means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Aloha Chooses Aloha Roof Pros
- ✓We read the truss framing from inside the attic before we price a single square, because on Aloha's housing the manufactured geometry overhead decides what is actually possible on the plane above it.
- ✓Our estimates are written per plane, so the trussed main roof and the addition or carport each get their own assembly rather than being averaged into one number that fits neither.
- ✓We refuse coating work over composition roofs and we say so in writing, because a film over granulated asphalt seals in moisture and puts the manufacturer's warranty out of reach permanently.
- ✓We will talk you out of a hail claim this climate does not support, since western Oregon sees severe hail rarely and a withdrawn claim sits on your loss history for years.

Quality here is not a matter of opinion — it is written down. The chimney flashing work we do in Aloha 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.
