UL 1897

Standard:  UL 1897:  Underwriter Laboratories Inc. Standard for Safety – Uplift Tests for Roof Covering Systems

Scope:  This test is applicable to a variety of residential and commercial roof covering systems and their method of attachment.

Applicable Products:  Metal and composite shingles, single-ply membranes, standing seam metal roof coverings, and even BUR (build-up roof) applications.

Test Procedure:  The test is regulated by incrementally raising the uplift static pressure of the roofing system test assembly by 15psf (0.72kPa) and holding for 1 minute.  The incremental increase of uplift pressure shall not be greater than 15psf (0.72kPa), and held for no less than 1 minute.  All pertinent vertical movement of the assembly is recorded.

End Result:  Typically this test is run to failure, which will provide information about adhesion loss, fastener pullout, and metal fatigue at specific wind uplift pressures.  A comprehensive test report will be issued at the completion of the test.
