The panelized roof sheathing construction system includes a plurality of panels attached to a building frame structure in substantially abutting relationship. Each panel includes a water resistant barrier layer secured atop the outward facing surface of the panel. The water resistant barrier layer includes a skid resistant surface. Joints between panels are sealed by strips of water resistant tape or the like. The panels are made of lignocellulosic material. The water resistant and skid resistant surface may include indicia for aligning strips of tape or for aligning fasteners. A method for manufacturing the water resistant building panels is also disclosed and includes the steps of feeding a roll of paper onto a forming belt, depositing lignocellulosic material and the binding agent onto the forming belt so as to form a lignocellulosic mat, cutting the mat and paper into segments of predetermined lengths, transferring the segments onto a loading screen, subjecting the segments to heat and pressure so as to impart the skid resistant surface on the paper, and cutting the segments into panels of predetermined sizes. A method of drying-in a building using the panels of the invention is also contemplated.
