The 4.5-inch maximum here meets or tops the 2-inch hail a roof covering must withstand for the IBHS FORTIFIED High Wind & Hail designation, and 6 of the 15 reports reached 1.75 inches. Half the homes here were built in 2004 or later, so a roof older than the July 13, 2011 storm may still be the original. (Insurance Institute for Business & Home Safety)
