Notice to Reader
Images used in a Construction Detail are representative and not intended in their representation of an assembly to be prescriptive. Nor are they necessarily drawn to scale. Rather, they are provided to visually convey the Standards, Guiding Principles and Recommendations of the RoofStar Guarantee Standards for a Waterproofing or Water-shedding System. Actual design with respect to dimensions, the selection of materials and their application remains the responsibility of the Design Authority.
