ASTM to develop vegetative roof standard

ASTM International has announced it is developing ASTM WK29304, "Guide for Selection of Roofing/Waterproofing Membranes for Vegetative Roof Systems," a proposed standard that will address how to determine the proper roof and waterproofing membrane for a vegetative roof system.

ASTM International Subcommittee D08.24 on Sustainability, part of ASTM Committee D08 on Roofing and Waterproofing, is developing the proposed new standard. Subcommittee D08.24 is working closely with ASTM Committee E60 on Sustainability regarding topics of mutual interest for roof systems.

"The growing move toward preserving our environment and reducing the effects of the urban heat island have encouraged many building owners and communities to select vegetative roofs," says Michael Sexton, senior systems engineer for Firestone Building Products Co. LLC, Indianapolis, and leader of the task group developing the proposed standard. "As such, each and every component plays an important role in the success, not only of the roofing, but to maintain and enhance the building envelope performance. The proper selection of a waterproofing barrier for the roof is critical to the success on both fronts."
