Gresham Roof Pros provides professional residential roof installation in Gresham, OR for residential and commercial properties across east Multnomah County. This page is the roof that goes on when there is nothing to remove: new construction, an addition, a second unit, a dormer or a garage conversion, and the deck that returns to bare wood because the plywood is being replaced. Tear-off work sits on our replacement page.
The permit answer flips completely between those two jobs, and almost nobody explains it. The Oregon Residential Specialty Code exempts reroofing a one- or two-family dwelling from a building permit, replacement of some or all of the sheathing included, with narrow exits for townhouses, wildfire hazard zones and photovoltaic roof coverings. New construction is not reroofing. It is permitted work with a framing and sheathing inspection before cover and a final afterward.
That means the roof on a new Gresham structure sits inside somebody else's inspection sequence. The deck has to be nailed and signed off before it can be covered, and until it is covered the building is open. We ask to be written into the framing schedule rather than called once the framer has gone, because the gap between those two events is the whole risk on this side of the state.
Which brings up the dry-in window, and in east Multnomah County it is a real scheduling argument rather than a talking point. A deck left open through a wet week does not simply dry out again, and the wind that takes roofs apart here comes down the Gorge from due east in the cold half of the year. We size each day's work to the forecast and close the dry-in the same day the deck opens.
Oregon also simplified the fire question in 2025. Senate Bill 83, signed on 24 July, repealed the statewide wildfire hazard map and voided the designations behind it, revising the residential code's wildfire section into something each municipality may adopt or ignore. We check what your jurisdiction has actually adopted before scoping a fire-rated assembly, because selling a Class A upgrade nobody requires is not a service.
The honest recommendation: if the builder already has a roofing crew on site with the framers, let them dry the building in. Speed beats specification here. Bring us the addition, the ADU, the custom build with no roofer attached, or the structure where new sheathing is the reason the roof is open at all.
Our 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 residential roof installation
The difference between residential roof installation that lasts and residential roof installation 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.
