Garage doors or roll‐up doors on residential and commercial structures have often been damaged in hurricanes, tornadoes, and high wind events, due to impacts from flying debris; positive or suction pressures; weak tracks on the doors themselves; and inadequate attachment of the doors to the building.

When it occurs, wind damage to garage and roll‐up doors often leads to damage to the adjacent roof, walls or both. Post‐event damage assessments of garage and roll‐up doors have typically been conducted on the ground where they were individually inspected. To explore garage door and associated roof damage for a large number of homes in historical events, IBHS collaborated with the University of Illinois at Urbana‐Champaign to analyze damage data in the following categories using remote‐sensing techniques:

• Garage door damage without roof damage
• Garage door damage with roof damage
• Roof damage without garage door damage

The events analyzed included the 2013 Moore, Oklahoma tornado, the 2011 Joplin, Missouri tornado and Hurricane Ike in 2008 (Galveston, Texas).
