FAQs about FORTIFIED Roof™
A FORTIFIED Roof can help protect against severe weather and may be eligible for insurance discounts, grants and other incentives in certain states.6
The FORTIFIED Roof™ program is a voluntary construction and re-roofing program designed to help protect against severe weather.
Initial FORTIFIED designation certificates expire five years from the date they were issued. At the end of that period, a redesignation inspection is required to maintain the home or business's current designation level.
