ANSI/SPRI ES-1 certification

NRCA's ANSI/SPRI ES-1 testing and certification listing of shop-fabricated edge metal

The 2003 and 2006 editions of the International Building Code (IBC) and some other building codes contain provisions requiring edge-metal flashings (copings, fascia, gravel stop), except gutters, to be designed and installed in accordance with ANSI/SPRI ES-1, "American National Standard for Edge Systems Used with Low Slope Roof Systems." For example, in the International Building Code, 2006 Edition, this provision reads as follows:

1504.5 Edge securement for low-slope roofs. Low-slope membrane roof system metal edge securement, except gutters, shall be designed and installed for wind loads in accordance with Chapter 16 and tested for resistance in accordance with ANSI/SPRI ES-1, except the basic wind speed shall be determined from Figure 1609.

Also, some project specifications contain provisions requiring edge-metal flashings comply with ANSI/SPRI ES-1.

To assist roofing professionals in complying with these provisions, NRCA has performed laboratory testing and maintains a certification listing based upon ANSI/SPRI ES-1 with Intertek Testing Services, N.A. (ITS), for specific edge-metal flashings that are included in the construction details section of The NRCA Roofing and Waterproofing Manual, Fifth Edition, and The NRCA Roofing Manual: Membrane Roof Systems—2007.

NRCA has performed this testing and maintains this certification listing to provide roofing professionals with the necessary design-resistance load data to use in conjunction with ANSI/SPRI ES-1 to comply with the building codes' provisions and project specification requirements.

Also, NRCA had made arrangements with ITS to allow specific NRCA members to be included in NRCA's ITS certification listing as authorized fabricators (also referred to as "additional manufacturers"). This designation signifies that the specific NRCA member companies have submitted to and successfully completed third-party verification of compliance with NRCA's certification listing. These companies are allowed to use ITS product certification mark labels on the specific edge-metal flashing products that comply with NRCA's certification listing.
