Roof Uplift Testing

Understanding wind uplift testing for standing seam roof systems ul 580.

Roof uplift testing. The ul 1897 wind test is a continuation of ul 580 and is the standard for uplift tests for roof. Purpose and scope. Fm global fmg recommends in its property loss prevention data sheet 1 52 field veriication of roof wind uplift resistance that ield uplift testing or full time rooing construction observation be conducted for most adhered rooing sys. Fm loss prevention data sheet 1 52 fm 1 52 field uplift tests provides for two methods of testing.

The test evaluates the roof deck how it s attached to supports and the roof covering materials. Know the parameters and use the information wisely test methods. Roof membrane uplift resistance testing your ally in roofing compliance unlike a building s interior components roofs are susceptible to severe weathering foot traffic expansion contraction and abuse which can result in accelerated roof system degradation. To overall monetary loss was roof failure due to strong winds.

For mechanically attached single ply roofing systems the test involves building a roof assembly on a test frame that measures 12 feet by 24 feet. This test determines the uplift resistance of roof assemblies consisting of the roof deck and roof covering materials by evaluating the comparative resistance of roof assemblies to positive and negative pressures. A common point of system failure occurs when fasteners shear or pull loose from the underlying roof sheathing. Tile uplift test a direct tensile load is applied by pulling up on the edge of the tile by using a tile testing scale this test verifies the tile can withstand the uplift it is designed for.

Major roofing contractor groups such as the national roofing contractors. The test evaluates the roof panel panel. While undergoing construction it is of paramount importance that the roof is monitored during the installation period. Test variables and concerns.

The ul 580 rating determines the uplift resistance of roof assemblies. In laboratory testing wind uplift forces are applied and carefully measured in pounds per square foot psf gradually increasing the psf force until roof system failure occurs. Review of applicable standards and industry practice. Ul 580 is the standard for tests for uplift resistance of roof assemblies.

The test frame has the appropriate roof deck attached to supports. The specific test that pertains to wind uplift utilizes a test apparatus designed by fm approvals.
