Wind Uplift Testing†
This test is conducted to check the ability of a standing seam roof system to withstand high winds that would create uplift on the roof of a building. When wind travels over a building, uplift is created by the void at the top of a wall.
This uplift pressure creates a suction on the roof of the building that can potentially cause damage to the roof system. The roof system is made up of the roof panel and the clip that is used to secure the panel to the substrate. To recreate this uplift in a controlled environment is difficult. Most testing simulates winds in excess on 100+ mph. Based on the test results, the roof system that is being tested is awarded a UL rating. Of course, as a builder, you are looking for the highest test results that you can. This ensures a great roof system that is dependable and you will not be afraid to stand behind in the years to come.
When the roof system is tested in a uplift facility, more often than not, it is a D.I. Roof Seamer seaming the panels together. We are proud of our quality products and our association with such strenuous testing procedures that mirror our own in-house quality control processes.
