Water-shedding Systems include roof coverings that, with the assistance of gravity, shed water away from the building but do not waterproof it. These systems are typically installed on slopes greater than 1:4 (3" in 12", or 14 degrees). Consult the RoofStar Guarantee Standards for guarantee requirements, Guiding Principles and Recommendations in any application.

The RoofStar Guarantee Standards for Water-shedding Systems include the following:

  • Architectural Sheet Metal (ASM) Systems
  • Asphalt Shingle Systems
  • Cedar Shake & Shingle Systems
  • Tile & Slate Systems


See Waterproofing Systems or Waterproofing Plazas, Promenades and Terraces for other RoofStar Guarantee Standards, or return to the Home Page.
