ABSTRACT
Assessing hail damage to concrete tile shingles can be difficult as the difference between footfall, hail impact, and other phenomena is not always clear. Further, during insurance claims the lower right hand corner breaks are often the subject of dispute as to whether or not they were caused by hail impact, thermal movement, or ice build up. This paper presents a brief literature review on hail damage to concrete tile shingles including discussion on the possibility of thermal expansion/contraction causing damage to lower right hand corners. Inspection methods are discussed and an analytical method is presented along with a case study in which the analytical method is utilized.
