About 40 Inches of Rain, Most of It Between October and January

The official rain gauge for this part of the county sits at Sea-Tac Airport, eight miles from downtown Kent. Its 1991–2020 normals come to 39.34 inches a year, spread over 156 days with measurable rain. Published estimates for Kent itself run a little higher, about 43 inches. Either figure is far more than a roof can shed without a working gutter system under it.
The timing matters as much as the total. October through January carries 21.7 of those inches, more than half the year's rain in four months, and November alone averages 6.31. On a 1,500-square-foot roof that is roughly 5,900 gallons in one month, all of it arriving at the eaves. A gutter that is full of maple leaves by Halloween sends that water over the edge onto the siding, into the fascia, and down against the foundation, which on the valley floor means a crawl space that stays wet until spring.
This site exists to get that fixed. Fill in the form below and it goes to one gutter contractor working south King County, registered with Washington L&I, who measures the roofline and quotes it: new seamless runs, a full replacement, guards for a house under big trees, a repair to a run that has pulled loose, or a downspout that dumps at the foundation.

Why Gutters Give Out Sooner Here
Bigleaf maples drop in October, Douglas firs drop all year
Two trees do most of the damage. Bigleaf maple leaves can reach a foot across, and when a mature tree over the roof lets go in October and November the wet leaves mat together and can fill a gutter run in a single storm. Douglas fir needles are the other problem: they shed in every season, slip through ordinary screens, and pack into a dense layer that holds water instead of passing it. A gutter under either tree needs cleaning at least twice a year or a guard chosen for that debris.
Moss grows wherever the gutter stays wet
A gutter that holds standing water and leaf litter is a planter. Moss takes hold on the shaded north side first, traps more debris, and holds moisture against the shingle edge and the fascia board. Oregon State's extension plant pathologist puts it simply: moss needs shade and moisture, and a gutter that never dries supplies both. Keeping the trough clear and the roof edge draining is the cheapest moss prevention there is.
Valley floor, East Hill, West Hill
Kent is three places. The valley floor along the Green River is flat, low, and slow to drain, so a downspout emptying at the foundation there feeds a high water table directly. East Hill and West Hill are the opposite: sloped lots where a downspout aimed downhill sends roof water onto a neighbor or toward a slope that county rules say to keep it away from. The drainage half of a gutter job depends on which of the three you are in, and a local contractor will know without being told.
Signs the Gutters Need Work Before the Rain Starts
- Water sheeting over the front edge in a moderate rain, even after a cleaning.
- A dark streak or peeling paint on the fascia board behind the gutter.
- Runs that visibly sag or hold a line of standing water after the rain stops.
- Downspouts that end at the foundation, or a splash block that has walked off.
- Moss or small plants growing in the trough.
- Bare soil, splash marks, or a trench worn into the mulch under the eave.
- A crawl space or basement corner that is damp on the side the downspouts serve.
One overflow in an atmospheric-river storm can happen to a good system. Overflow in ordinary November rain means the gutters are undersized, blocked, or mis-pitched, and every week it goes on is water soaking the fascia and the ground at the footing.

Kent Gutter Questions
How much do new gutters cost in Kent?
Seamless 5-inch aluminum runs about $6 to $13 per foot installed here, 6-inch about $8 to $15, so a house with 150 to 200 feet of eave lands between roughly $1,500 and $4,000. Steel and copper cost more; guards add about $7 to $35 per foot. Fascia repair found at tear-off is the most common addition. The cost guide breaks it down.
Do I need a permit to replace gutters in Kent?
Replacing gutters on an existing house is ordinarily treated as maintenance, like re-roofing or re-siding, which King County lists as exempt from a building permit. The City of Kent publishes its own exemption list, and a contractor who works the city regularly knows it. Connecting a downspout to the public storm system is the one part of the job that can involve the city; see downspouts and drainage.
Are 6-inch gutters worth it for a Kent roof?
A 6-inch K-style gutter carries about 2 gallons per foot against about 1.2 for a 5-inch, for a premium of roughly $1 to $4 per foot. On a large roof, a steep pitch, or a long run feeding one downspout, the extra capacity keeps November rain in the trough. Smaller single-story roofs rarely need it. Sizing is covered under seamless installation.
When is the best time to have gutters installed in Kent?
Late summer and early fall, before the October rain begins and while the fascia is dry enough to inspect. Contractor calendars fill from September on, so a quote in August gets the work done before the bigleaf maples drop. Winter installs happen too and work around the weather.
