Weather and gutters in Mercer Island
NOAA Atlas 14 does not cover Washington and Oregon, so there is no current federal estimate of the short downpour for Mercer Island; 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 Mercer Island
Half the homes in Mercer Island were built by 1973, 61% 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.
66% of households own their home, and 66% of homes are detached houses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.
