COMMON ERROR Why Defy Gravity? Too often, damage and water leakage around windows can be traced to the simple installer error of putting overlaps in the wrong direction. Remember, water flows from top to bottom. If it finds a gap, it will enter. Plywood sheathing that remains at a 19 percent moisture level (easy to do if flashing is done wrong) can quickly become a problem. Vendors: We will supply this image.
