||New Guide for Sprayed Polyurethane Foam Roofing Systems
ASTM Standard D 6705, Guide for the Repair and Recoat of Sprayed Polyurethane Foam
Roofing Systems was approved August 10 for roofing consultants,
inspectors, architects, engineers, building owners, contractors,
material suppliers, and building code officials.
The new guide will provide the building industry with peer-reviewed
procedures for inspecting and evaluating the condition of an existing
SPF [sprayed polyurethane foam] roof and procedures to make recommendations
on repair and recoat, said ASTM member Mason Knowles, technical
director for the Spray Polyurethane Foam Alliance (SPFA) as well
as acting technical director of Building and Construction Issues
for the American Plastics Council.
Application of D 6705 can result in an increase of SPF roofs being
repaired and recoated correctly, thereby extending the performance
life of the roof, Knowles explained. In addition some specifiers/
consultants will be more likely to recommend repair and recoat
over tear-off and replacement, thereby protecting the interior
of the building from potential damage during tear-off and saving
enormous amounts of construction debris from going to landfills.
A large task group of ASTM Subcommittee D08.06 on Spray Polyurethane
Foam Roof Systems under Committee D08 on Roofing, Waterproofing and Bituminous Materials has been developing
the guide since 1998. Chaired by Knowles, the group included architects,
engineers, roofing consultants, contractors, material suppliers,
researchers, and members of the SPFA and the National Roofing
Use of the standard can facilitate better recoat vs. replacement
decisions by design or consulting professionals, and enhanced
repairs/recoats on existing SPF roofing systems by the contractor
and supplier community, Knowles affirmed.
