Composite Decking and local data in King County
Composite's main tradeoff is surface heat, and in King County's covered ZIP codes sees about 2 days a year at 90°F or above. Color can be chosen mostly on looks, though full-sun decks still run cooler in lighter tones.
About 95 wet days and 24 freeze-thaw days a year make moisture-resistant capped boards a practical advantage over unsealed wood.
With 49% detached homes, many projects in King County's covered ZIP codes re-deck an existing frame, so joist spacing must be checked against the board's span rating first.
