The 2-inch maximum here meets or tops the 2-inch hail a roof covering must withstand for the IBHS FORTIFIED High Wind & Hail designation, and 5 of the 27 reports reached 1.75 inches. Half the homes here were built by 1955, so the date your roof was last replaced tells you more than the age of the house. (Insurance Institute for Business & Home Safety)
