A board that is correctly installed right side up (or bark side down) will form a crown and allow water to run off the edges.

Should a deck slope?

Wood shrinks and swells twice as much in the direction parallel to the growth rings as it does perpendicular to the growth rings.
Do pressure treated deck boards shrink?
Even products that are sealed and treated are going to shrink. This most typically occurs across the width of boards, so builders should take into consideration the fact that their lumber will shrink over time. Additionally, as part of the drying stage of treated wood, the boards will crack, also referred to as checks.
Do deck boards shrink or expand?
Any type of decking board will expand and shrink, whether it’s wood, plastic, or composites. … However, they don’t change in size as much as wood or plastic. Wood fibres hold the shape when the composite undergoes thermal expansion, while the plastic fibres do the same when moisture is involved.
