Understanding Wind Uplift Ratings

DECRA Metal Roofing conducts wind uplift lab tests per UL 1897 test standard to meet compliance for most U.S. code jurisdictions abiding by either the International Residential Code (IRC) or the International Building Code (IBC) standards.

When it comes to roofing, one of the most important attributes of roof system design is wind resistance. Wind uplift ratings are a critical safety metric for building and testing roof systems for superior wind performance. Wind uplift is a near-constant force on roofs with wind movement from zero to over 170 mph. Although none of the systems devised are fool-proof, they can help you compare roofing construction and the probability of failure for each roof system you consider.

It’s important to remember that building codes are the minimum requirements. Buildings can be, and often should be, designed to better-than-code requirements. The conservative approach to wind resistance design is to believe “not if – but when” a major wind storm event will be encountered virtually anywhere throughout the Americas.

DECRA’s higher tensile strength steel specification, along with its roof system fastener specification and labtest installation requirements help ensure that you are receiving an outstanding roof system with exceptional strength-to-installed-weight ratio – well exceeding numerous competitive choices offered in the asphalt and tile roof industry for steep-slope roofing applications.
