Gutter Cleaning in Gresham, OR

Clearly Amazing cleans gutters in Gresham, Oregon’s fourth-largest city and the eastern anchor of Multnomah County. Our office is on SW 74th Avenue in Tigard and we work the whole metro. What makes gutter work different in Gresham is the wind. The city sits near the western mouth of the Columbia River Gorge, and the east wind that comes out of it moves more material into a gutter here than an ordinary week of rain does.

The east wind fills your gutters faster than the rain does

Gresham sits at the western end of the Columbia River Gorge, just west of Troutdale. When high pressure builds east of the Cascades, air is forced through the gap and comes out over east Multnomah County as a cold easterly. This is not local folklore: published climatology in the American Meteorological Society journal Weather and Forecasting (Bell and colleagues, 2004) documents that these gap-outflow easterlies are both more frequent and stronger near the Gorge’s western terminus than at other lowland stations west of the Cascades, and the National Weather Service issues warnings during the strongest events.

Here is what that means on a roof. Rain falling straight down loads a gutter gradually and fairly evenly. A strong easterly strips a tree in an afternoon and drives the debris sideways into the east-facing side of your house, the upwind end of each run, and the valleys where two roof planes meet. Half the run looks clear from the driveway while the end the wind has been feeding is packed solid.

The other half of the problem is wind-driven rain. In a still shower, water lands on the roof and goes where the roof sends it. In an east wind a good deal of it never reaches the gutter at all: it is pushed against siding, window heads and the underside of the eave on the exposed elevation — the same elevation the wind has just loaded with debris. That is why so much of what we find here is concentrated on one side of the house. The same research notes that a large share of the region’s winter snow and freezing rain arrives with easterly Gorge flow, so the gutter carrying that extra weight is often the one packed the week before.

Long ranch runs, and the section that fills first

Gresham grew faster than almost anywhere in the state after the war: 3,944 people in 1960, 65,235 by 1990, with the largest single jump of more than 35,000 coming in the 1980s on the back of large annexations of west Gresham. Berry farmland went to developers, and the housing from that stretch is dominated by the boxy ranch and split-level homes typical of the 1960s and 1970s.

Two things follow. A ranch gives you a long, low run draining to one or two downspouts, so a partial blockage backs water a long way before anything shows at the front of the house, and the shallow pitch leaves little margin once the trough is full. A split-level gives you the opposite: an upper roof plane discharging onto a lower one, so a short section takes a whole roof’s worth of water. Add a wind that loads from one direction and the section that fills first stops being a mystery. It is usually not the length you can see from the front door.

What the job involves

Every visit runs the same three steps.

Areas we cover in Gresham

The City of Gresham officially recognizes 16 neighborhood associations, coordinated through the Coalition of Gresham Neighborhood Associations. We work all of them, plus the surrounding east county area.

• Rockwood, Wilkes East, Northeast and North Gresham — the older, denser districts.
• Centennial, Historic Southeast, Southwest, North Central, Central City and Northwest — postwar and annexation-era stock, where the long ranch runs turn up most.
• Gresham Butte, Hogan Cedars, Kelly Creek, Hollybrook, Powell Valley and Gresham Pleasant Valley — the higher, hillier ground on the eastern and southern edges, with more mature planting overhead.

The city is largely flat, with hills on its eastern edge toward Troutdale. Powell Butte sits just over the Portland line to the west.

When to schedule in Gresham

September through the first half of October is the best window here. The wet season across the Portland metro runs roughly from mid-October to early May, and the east wind events that do the most loading come with the cold months. A system cleared in early fall goes into all of it empty.

Any other time of year is a good time to have it done, and people book year-round for real reasons: a listing, a downspout overflowing in January, or simply wanting it off the list. Gutters cleared in April go into the next fall in better shape.

A second visit in the year is worth it if any of these apply:

• An exposed east elevation. The side facing the Gorge takes the most wind-driven debris and often needs clearing first.
• A split-level, or any upper roof plane draining onto a lower one. Those short sections load several times faster than an open run.
• Mature trees over the roofline. Established canopy on the larger lots toward Gresham Butte and Powell Valley can refill a run on its own.
