21. A: An ice & water shield product is required at all curved and tapered roof applications, and should be used at all critical areas, such as hips, skylights, valleys, ridges, dormers, rake edges (gables), eaves, low slope areas, and slope changes or tie-ins. An ice & water shield product may be substituted for the 2 layers of 30# felt on slopes 3:12 or less.
