ACRYLIC ROOFING:  POSTS

Posts have four outside corners, so the flashing technique is very similar to that for outside corners. If the posts are made of wood, use only quality kiln-dried lumber, preferably laminated to resist warping. To prevent water flow behind the acrylic flashing, cap post tops and paint or seal the post sides. Follow these procedures just before beginning to waterproof the main roof surface.
