Aloha Roof Pros provides professional flat & low-slope roofing in Aloha, OR for residential and commercial properties across the Tualatin Valley. Nearly every low-slope plane in Aloha sits above something added after the house was finished. A carport that got walled in. A family room pushed out the back. A covered walk connecting the house to a detached garage.
Which means these planes are typically the one portion of the roof that is not trussed. Somebody framed them on site with dimensional joists, frequently to a different standard than the manufactured roof they tie into, and occasionally without a permit ever being pulled. Two framing systems on one house, two separate sets of answers. A look from inside settles it, since a trussed plane shows web members and a site-framed one shows plain joists.
We handle them as separate roofs, because that is what they are. The addition gets its own deck inspection, its own slope reading, its own membrane specification and its own line on the estimate. Folding it into the main roof number is exactly how these planes end up wearing the wrong assembly for thirty years. Slope is worth measuring rather than eyeballing, because a plane reading as flat often carries real fall.
For most of them a self-adhered modified bitumen system is the correct call. It copes with a shallow pitch, it terminates cleanly against the wall of the main house, and it goes down without heat on a deck that may well be older and drier than it appears from underneath. Ponding is what kills these roofs, so we build fall with tapered insulation wherever the existing framing does not provide enough of it.
Where the plane is large enough and the deck sound enough, we will price a mechanically attached single-ply membrane instead, hot-air welded at the seams and flashed up the adjoining wall with counterflashing set into a cut reglet rather than run as a bead of sealant across painted siding. Seam welds get probed with a hook the same day they are made, which is the only way to know a weld took.
The junction where a shallow plane meets the trussed body of the house is the detail that determines whether any of it lasts. It has to tolerate slight seasonal movement between two structures that behave differently through a wet winter, and a rigid sealed joint there will reopen within a couple of years. So we detail it as an expansion joint with a cover flashing rather than trying to glue two buildings together and hoping neither one moves.
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 flat & low-slope roofing
The difference between flat & low-slope roofing that lasts and flat & low-slope roofing 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.
The standards behind flat & low-slope roofing
Quality here is not a matter of opinion — it is written down. The flat & low-slope roofing 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.
Every flat & low-slope roofing project in Aloha gets the same attention, whether it is a single room or a full commercial job. We show up on schedule, keep the site clean, and stand behind the work — the estimate is free and there is no pressure.
