Roof evaluations for hail damage often include roof core sampling and laboratory testing. For multi-ply bituminous membranes (e.g., built-up roofs and modified bitumen roof membranes), this testing commonly includes delamination testing of the membrane plies to evaluate both the plies and the interply bitumen for damage from impact forces.

This year marks the 20th anniversary of Hurricane Katrina (August 2005), one of the most devastating hurricane events on record, and a storm that caused significant damage from storm surge.
