NRCA Announces Updates to Roof Wind Designer Online Wind-Load Calculator

ROSEMONT, IL – April 13, 2015 – The National Roofing Contractors Association (NRCA) has announced the update of Roof Wind Designer, an online wind-load calculator intended to provide roofing professionals with an easy way to determine a roof system's design wind loads for many commonly encountered building types subject to code compliance.

Roof Wind Designer was developed in cooperation with the Midwest Roofing Contractors Association (MRCA) and North/East Roofing Contractors Association (NERCA).

The free Web-based application is based on ASCE 7, "Minimum Design Loads for Buildings and Other Structures", 2005 and 2010 editions. ASCE 7 is a widely recognized consensus standard method for determining design wind loads on buildings and other structures.

Roof Wind Designer has also been updated to determine design wind loads applicable to perimeter edge-metal flashing system design, which helps compliance with ANSI/SPRI ES-1 requirements.

The application is limited to building heights less than 60 feet and is applicable to roof systems with slopes up to 12:12 and hip roofs with slopes up to 6:12.
