How Rockford's Climate Affects Deck & Patio
In Rockford's freeze-thaw climate, composite decking is the strongly preferred choice over pressure-treated wood. Wood absorbs moisture and expands and contracts with each freeze-thaw cycle, accelerating splits, cupping, and fastener pullout within 5–8 years. Quality composite maintains its shape through extreme temperature swings and eliminates the annual sealing requirement.

Quality composite maintains structural integrity through extreme temperature ranges and requires no annual sealing.
