Roof Uplift Testing

Ul 580 is the standard for tests for uplift resistance of roof assemblies.

Roof uplift testing.

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. A common point of system failure occurs when fasteners shear or pull loose from the underlying roof sheathing. The test frame has the appropriate roof deck attached to supports. Purpose and scope.

The ul 580 rating determines the uplift resistance of roof assemblies. 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. Major roofing contractor groups such as the national roofing contractors. 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 is done to measure the uplift resistance for adhesive foam or mechanically attached tile roof systems. Test variables and concerns. In fact there are various. Understanding wind uplift testing for standing seam roof systems ul 580.

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. 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. The test evaluates the roof panel panel. 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.

The ul 1897 wind test is a continuation of ul 580 and is the standard for uplift tests for roof. While undergoing construction it is of paramount importance that the roof is monitored during the installation period. The specific test that pertains to wind uplift utilizes a test apparatus designed by fm approvals. The test evaluates the roof deck how it s attached to supports and the roof covering materials.

To overall monetary loss was roof failure due to strong winds. Review of applicable standards and industry practice.
