Weather and gutters in Sumas
NOAA Atlas 14 does not cover Washington and Oregon, so there is no current federal estimate of the short downpour for Sumas; 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 Sumas
Half the homes in Sumas were built by 1983, 48% before 1980 (ACS 2020–2024). In a neighborhood that age, many houses are on their second set of gutters or due for one, and the fascia board behind them is worth checking at the same visit. 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.
69% of households own their home, and 69% of homes are detached houses, 3% townhouses. Where an HOA governs the exterior, its rules on gutter color and style apply before any order is placed.
