Hail damage claims, like most claims are unique to themselves. Questions that have to be answered in favor of the homeowner include, 1) when did the damage occur, 2) is the damage real damage versus cosmetic damage, 3) was there any damage already existing on the roof, 4) is hail the sole cause of the damage or were there other causes of damage, 5) is wear and tear an issue? These and other factors are sometimes obvious. But, at other times an expert is needed.
The Southern District of Texas, Houston Division, issued a 2021, opinion which is a summary judgment opinion wherein an expert was needed. The opinion is styled, Dustin Farris v. State Farm Lloyds. This is a case where the expert did much more harm than good. The discussion of his opinion shows how obviously bad the expert report he wrote is bad.
The Court spent much time discussing how summary judgment is decided.
