Hail Storm Evaluation and Investigations The hail storm on April 9, 2013 produced pea size to quarter size (1") hail. WKBT News reported that the storm was not classified as severe, since the hail was not larger than 1" and winds were less than 58 mph. This event was much less damaging than the July 19, 2004 storm, when hailstones were as large as 2.5". Bangor received 3.5" hail during the June 6, 2007 storm, causing $600,000 worth of property damage. Calvert received $25 million worth of damage from the 2"-2.5" hailstones during the April 10, 2011 storm.

Wisconsin ranked 25th for major hail events in 2012, according to the National Oceanic Atmospheric Administration (NOAA). Nationwide, hail insurance claims total $1 billion of damage to property and crops each year. Typically, 1" hail or larger causes damage to roof coverings and exterior surfaces, but depending on the material and existing condition smaller hail can also produce damage. Hail is often part of other severe weather damage, including tornados, thunderstorms or lightning strikes.

Hail Damage Evaluations for La Crosse Commercial Properties

Commercial properties have a wider variety of roof coverings. Apartment complexes may have roof coverings similar to sloped single-family house roofs, or they may have flat roofs with or without decorative mansards. Strip malls, office buildings or industrial/warehouse buildings may have a single uniform roof covering or a combination of several types and with varied useful-life stages. ESI is familiar with the special characteristics of each type of covering and how hail damage affects the remaining useful life of the product.
