Tigard Roof Pros provides professional flat & low-slope roofing in Tigard, OR for residential and commercial properties across Washington County. Low slope turns up in Tigard on rear additions, over garages, on carports, on mid-century sections of otherwise pitched houses, and on the one and two-story buildings along the main corridors. It is a different trade from shingle work, and it fails in different ways.
The defining problem in this climate is not heat, it is standing water and how long it stands. A roof that holds a quarter inch of water for two days in Arizona dries out. Here, from November through April, it does not, and every seam, lap and penetration sitting in that pond is loaded continuously for months instead of for hours.
Drainage is therefore what we look at first, and usually what we fix first. Tapered insulation to move water toward the drain. Crickets behind curbs and chimneys. Drains and overflows that are genuinely open. A scupper that is not set two inches above the low point of the roof. A membrane over a drainage defect fails early, whatever it cost. Fixing the slope first is cheaper than doing the roof twice.
For the membrane we work in TPO at 60 and 80 mil, in EPDM, and in granulated-cap two-ply SBS modified bitumen, chosen by what the deck and the exposure require rather than by whatever happens to be on the truck. Fully adhered systems outperform mechanically attached ones on the exposed, wind-loaded low-slope sections common around here, and the difference tends to show up in the first hard winter rather than the fifth.
On a small residential low-slope section, torch-applied modified bitumen is often the right answer and often the cheapest, and we say so even though it is the least exciting product we sell. It tolerates ponding, it tolerates foot traffic from whoever services equipment up there, and it stays repairable by any competent roofer for the next twenty years.
One thing we will not do is roll a coating over a wet assembly. If the insulation below the membrane is saturated, a coating seals the water in, buys you two years, and enlarges the eventual tear-off. We core the roof to find out which situation we are in. If it is wet, the answer is replacing that section, and we would rather say so plainly than sell you a coating you are going to regret.
Our licensed and insured team brings the right materials and equipment to every job — mechanically seamed 24-gauge steel roof panels, self-adhered bituminous membrane at valleys and penetrations, 1x skip sheathing and half-inch plywood decks, continuous ridge venting paired with clear soffit intake, baffles that keep blown-in insulation off the eave vents, step flashing and counterflashing at sidewall terminations — and backs the work with a written workmanship warranty. We serve Tigard and nearby communities including Beaverton, Tualatin, Sherwood, King City.

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 mechanically seamed 24-gauge steel roof panels, self-adhered bituminous membrane at valleys and penetrations, 1x skip sheathing and half-inch plywood decks, continuous ridge venting paired with clear soffit intake, 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 Tigard 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 Washington County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Tigard Chooses Tigard Roof Pros
- ✓We tell you which side of Oregon's permit-exemption line your roof sits on, in writing, before we price it. That single distinction is where most of the spread between competing bids actually comes from.
- ✓A permit-exempt re-roof is never seen by a building inspector, so we photograph the bare deck the moment the tear-off is done and send it to you before any underlayment covers it up.
- ✓We quote access as its own line. Skinny-lot infill, shared flag drives and second dwellings have taken the boom-truck approach away from a lot of older lots here, and hand-carrying material is real labor that belongs on paper.
- ✓We do not chase weather events, and nobody from this company is going to knock on your door. Damaging hail is close to absent west of the Cascades, and any roofer who tells you otherwise after a thunderstorm is selling something.
