Roof Uplift Testing

Purpose and scope.

Roof uplift testing.

A common point of system failure occurs when fasteners shear or pull loose from the underlying roof sheathing. The ul 1897 wind test is a continuation of ul 580 and is the standard for uplift tests for roof. The test frame has the appropriate roof deck attached to supports. 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.

Review of applicable standards and industry practice. The ul 580 rating determines the uplift resistance of roof assemblies. 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. 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.

Know the parameters and use the information wisely test methods. Ul 580 is the standard for tests for uplift resistance of roof assemblies. This test is done to measure the uplift resistance for adhesive foam or mechanically attached tile roof systems. 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.

Wind uplift test starting at 800. To overall monetary loss was roof failure due to strong winds. Understanding wind uplift testing for standing seam roof systems ul 580. Attachment calculations for approved roofing assemblies 250.

Test variables and concerns. Roof moisture surveys starting at 650. The test evaluates the roof panel panel. The test evaluates the roof deck how it s attached to supports and the roof covering materials.

Major roofing contractor groups such as the national roofing contractors. In fact there are various. 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. Uplift tests are typically carried out in high risk hurricane zones hvhz.

While undergoing construction it is of paramount importance that the roof is monitored during the installation period. Fm loss prevention data sheet 1 52 fm 1 52 field uplift tests provides for two methods of testing. Roof overs aka recover roofing we can provide you with the required testing.
