OSB
Oriented strand board - an engineered panel of glued wood strands, commonly used as roof decking instead of plywood. It is easy to spot by the flake pattern; it holds fasteners well while dry, but once it gets wet it swells at the edges and loses that grip, so it draws close attention on water and storm claims.
