Alligatoring is a sign that a roof is aging. Mild alligatoring can be repaired, but severe alligatoring can mean a roof needs to be replaced.

Damaged perimeter metal and membrane wall flashing at the outer edges or parapet walls of a building is a common roof leak area. Perimeter flashing can be damaged due to high winds, improperly installed at roof edges and parapet walls, or shrinkage of the membrane can occur over time.
