Three of SPRI's roofing
standards
have been approved by the American National Standards Institute
(ANSI).
SPRI, the association representing sheet membrane and component suppliers to
the commercial roofing industry, announced that three of its roofing standards
have been approved by the American National Standards Institute
(ANSI).
The key standards approved by ANSI include:
ANSI/SPRI RP-14 2010 Wind Design
Standard for Vegetative Roofing Systems – produced in partnership with Green
Roofs for Healthy Cities; ANSI/SPRI/FM 4435-ES-1 2010 Wind Design Standard for Edge Systems Used
with Low Slope Roofing Systems ; and, ANSI/SPRI IA-1 2010 Standard Field Test Procedure for
Determining the Mechanical Uplift Resistance of Insulation Adhesives over
Various Substrates. All three standards will be posted on SPRI’swebsiteand may be
downloaded free of charge.
ANSI/SPRI RP-14 2010Wind Design Standard for Vegetative Roofing
Systems provides design guidelines associated with wind uplift and stone
scour; defines items such as set backs from the edges of roofs in areas with
high winds, use of wind erosion mats, as well as edging details. There is also a
discussion of the various types of materials and their behavior under varying
wind conditions.
ANSI/SPRI/FM 4435-ES-1 2010Wind
Design Standard for Edge Systems Used with Low Slope Roofing Systems
provides the basic requirements for wind-load resistance testing and design for
roof-edge securement, flashing systems and nailers. It also provides minimum
fascia thicknesses that lead to satisfactory flatness, and designs to minimize
corrosion. It is intended for use with the specifications and requirements of
the manufacturers of the specific roofing materials and the edge systems used in
the roofing assembly, excluding gutters. The latest revision to ES-1 combines
the performance requirements included in the current version of ES-1, and has
been expanded to include requirements addressed in FM4435.
ANSI/SPRI IA-1 2010Standard Field
Test Procedure for Determining the Mechanical Uplift Resistance of Insulation
Adhesives over Various Substrates was developed to provide a uniform field
testing procedure for determining the suitability of using an insulation
adhesive for insulation or cover board attachment to a substrate. This standard
is intended primarily for situations when an existing roofing system is being
replaced or recovered and the general condition of the substrate is in
doubt.
This procedure, however, is also applicable to new construction. The
uplift data obtained provides the roof system manufacturer, adhesive
manufacturer and design professional with pull resistance values that will
assist in verifying the suitability of the intended design. The standard was
first approved as an American National Standard in 2005. It has been revised and
has been re-approved by ANSI.
