Construction Details for SBS-modified Bitumen Membrane Roof Systems
SBS Systems page thumb.JPG
The drawings linked on this page are intended to represent a variety of SBS-modified Bitumen Membrane roof system applications while remaining generic with regards to manufacturers’ specific application specifications. They do not represent all possible manufacturer application roof system designs. Consult each manufacturers’ specifications and the RoofStar Guarantee Standards to develop a system acceptable to both the manufacturer and the RoofStar Guarantee Program.
For further information about SBS-modified Bitumen Membrane System designs and requirements, see the Standard for SBS-modified Bitumen Membrane Roof Systems.
