When to clean gutters in Shoreline

The first fall frost comes around November 23 in a typical year here, and the last spring frost around March 8 (median dates, NOAA normals). A fall cleaning set for the weeks after that frost, when the branches over the house are bare, gets the year’s leaves in one trip; a spring visit follows once the pollen and catkins have come down.

When to clean gutters explains how the trees over a roof change the schedule.

Weather and gutters in Shoreline

NOAA Atlas 14 does not cover Washington and Oregon, so there is no current federal estimate of the short downpour for Shoreline; NOAA plans published Atlas 15 estimates for the lower 48 states no earlier than September 2027. Here gutters are sized from the roof and the local building department’s design rate.

The houses in Shoreline

Half the homes in Shoreline were built by 1968, 67% before 1980 (ACS 2020–2024). Houses that age have often had their gutters replaced once already; if not, the original runs and the boards behind them deserve a close look. On a house built before 1978, replacing more than 20 square feet of painted fascia or trim falls under the EPA’s lead-safe rule, so ask whether the crew is certified.

67% of households own their home, and 64% of homes are detached houses, 5% townhouses. If an association maintains the exterior, the gutters may be its job rather than yours; check before calling.

Hiring in Washington
