Photo #: 012 Alligatoring Photo #:012 Severity:Moderate Details: The cracking of the surfacing bitumen asphalt which occurs during the aging process in which the loss of volatile oils and the oxidation brought about by solar radiation; produces a pattern of cracks similar to an alligator's hide. The cracks may or may not extend through the surfacing bitumen. When alligatoring cracks extend through the entire waterproofing surface, the underlying felts can become exposed to moisture, which will progressively cause the strength in the felts to decrease. Splitting of the roof membrane may result.
