Roof Uplift Testing

Test variables and concerns.

Roof uplift testing.

The specific test that pertains to wind uplift utilizes a test apparatus designed by fm approvals. Ul 580 is the standard for tests for uplift resistance of roof assemblies. A common point of system failure occurs when fasteners shear or pull loose from the underlying roof sheathing. To overall monetary loss was roof failure due to strong winds.

Purpose and scope. The ul 580 rating determines the uplift resistance of roof assemblies. The ul 1897 wind test is a continuation of ul 580 and is the standard for uplift tests for roof. 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.

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. The test evaluates the roof panel panel. 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. Review of applicable standards and industry practice.

This test is done to measure the uplift resistance for adhesive foam or mechanically attached tile roof systems. In fact there are various. The test evaluates the roof deck how it s attached to supports and the roof covering materials. Fm loss prevention data sheet 1 52 fm 1 52 field uplift tests provides for two methods of testing.

While undergoing construction it is of paramount importance that the roof is monitored during the installation period. Major roofing contractor groups such as the national roofing contractors. 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. 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.

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