How many roofs collapse in a year in the US due to rain?

While specific statistics on the number of roofs that collapse each year in the U.S. solely due to rain are not readily available, it is estimated that thousands of roof failures occur annually due to various weather-related factors, including heavy rain and snow. Roof collapses can result from the accumulation of water and debris, particularly on flat roofs. Local building codes, roof maintenance, and design play significant roles in preventing such incidents. For precise figures, local building departments or insurance claims data may provide more specific insights.
