FM RoofNav

In March, FM Approvals debuted RoofNav, a Web-based version of its Approval Guide. RoofNav offers a simplified means of determining roofing product and roof system compliance with FM Approvals' guidelines and standards.

How it works

RoofNav, which can be accessed at, allows users to access roofing-specific portions of the Approval Guide through a series of online tools and comprehensive search capability; it also provides access to FM Global's Property Loss Prevention Data Sheets. Using RoofNav, users can configure specific components into roof systems and determine the systems' approval classifications.

Upon accessing the site, background information regarding RoofNav is available and registered users can log in. New users also can register from this screen.
