ACRYLIC ROOFING:  OUTSIDE CORNERS

The intersection of two vertical walls with a roof is called an "outside corner" if the walls intersect at an angle measuring more than 180°. Although the illustrations show a 90° angle, the same procedure works for other angles. Follow these procedures just before beginning to waterproof the main roof surface.
