RoofStone follows the roof contour and can be used to create walkways, patios, and landing areas on most non-ADA compliant roofs.
RoofStone can also be used on roofs that must be ADA-compliant with slope up to 1:48, which equals 2.08% or 1.19 degrees. This is ¼ inch per 1 foot, which is the norm (minimum) roof slope for drainage.
