Colfax is the seat of Whitman County and its second-largest city, with 2,782 residents at the 2020 census. It sits among wheat-covered hills at the forks of the Palouse River, about 33 km north-west of Moscow and about 22 km from Pullman by straight line. As the county seat it carries the county's older civic and commercial buildings alongside its houses, and that mix of building types makes it a different roofing town from the residential Palouse towns around it.
Colfax is Washington work. The contractor registers with the state Department of Labor & Industries, and the registration, bond and insurance requirements are Washington's, not Idaho's. Projects outside city limits take Whitman County's own design snow load, and the county building official confirms it for the address. A roofer who quotes Colfax work should be able to name the Washington registration held and the office that will issue the permit.
Local weather drives activity here: heat, humidity and rain change what shows up week to week.
The note on file says that as the county seat, Colfax carries older civic and commercial buildings, and that is where low-slope and flat roofs turn up on a map otherwise dominated by steep pitches. A low-slope roof drains more slowly than a pitched one, so the drains, the scuppers and the seams at the parapets carry the water away. A crew checks those parts before it looks at the membrane.
Flat sections on older buildings are checked for ponding, for blistered or split seams, and for the flashing at walls and roof penetrations. A technician asks how long a section has held water and where the water stands after a rain, because standing water is the detail that predicts the next leak. A repair that patches the surface without fixing the drain tends to fail in the same place the following season.
The county building official confirms the design snow load for a Colfax address outside city limits, and that figure is the one to use for the job. This page prints no pounds-per-square-foot number for Colfax. Pullman's published figures are for Pullman, and comparing a Colfax roof to them would say something the sources do not establish.
Snow collects at valleys, at parapets and at roof offsets, and that is the detail a crew looks for on any building with a raised edge or a change in roof height. On a larger building in town the drift can sit against the parapet for weeks, so the crew checks how the snow lies and where the water runs when it thaws. The point is not a load number. The point is where the snow will go.
The best documented wind in this part of the Palouse includes the December 2006 storm, when Colfax recorded a reported 77 mph gust on West Hill. The same storm brought gusts of 61 mph at Pullman, with the College Hill area of Pullman among the hardest hit. Colfax and Pullman are close enough to share a weather system, which is why the records for one are a fair guide to the other.
The Palouse also had a December 2000 storm with a 63 mph gust at Pullman, which brought down trees and power lines across the area. Because the hills vary street by street, a roof on a ridge sees the wind before one in a hollow does. The National Weather Service and NOAA's Storm Events Database are the places to confirm each reported gust, and a homeowner should check those records rather than rely on memory of the storm.
The walk starts at the edges. Fallen branches on the roof, missing ridge caps, lifted sections of flashing and gutters pulled from the fascia all point to where wind got under the covering. On the flat sections the crew checks for seams that have opened and for debris that has blocked a drain, because a blocked drain is the quickest way to turn a storm into a leak.
The homeowner can photograph visible damage from the ground and note the date of the storm before anything is moved. A crew confirms the damage on the roof itself, and separates what the storm did from what was already wearing out. The written report says which is which, so the homeowner can see the difference between a storm repair and an older one that was overdue.
Low-slope and flat sections on older county-seat buildings need their own check for ponding, seams and drains.
A leak on a flat section is traced back to the seam or drain that let the water in, which is often not directly under the stain.
The December 2006 gust record gives wind work in Colfax its local context, and the crew checks the edges first.
A replacement on a larger building is scoped around its low-slope sections as well as its pitched ones.
Chimney and wall flashing on older buildings is checked where wind lifts the edges and water sits behind the flashing.
Snow retention is discussed over entrances on metal roofs, where the release of a snow slab is the risk.

Washington. Colfax is the Whitman County seat, so the Washington State Department of Labor & Industries sets the contractor registration rules. An Idaho registration does not cover work here.
Flat and low-slope work is a roofing specialty, and a contractor's registration covers the specialty it holds. Ask the contractor which specialty applies to the job before agreeing a scope.
The Whitman County building official confirms the design snow load for the address. Pullman's published criteria are not a Colfax document, and they should not be used as one.
Photograph the damage from the ground, note the date, and call. A technician checks the edges and any flat sections on the roof itself before recommending a repair.
The city or county building office confirms whether a permit applies and what it requires for the building. This page prints no fee or form for Colfax, so ask the office directly.
