Ice & Water Shield

QUIK-Stick Ice & Water Granular is an SBS modified self-adhering membrane reinforced with non-woven fiberglass mat for extra strength and durability. QUIKStick IW is a highly versatile underlayment that provides superior waterproof integrity and is an excellent second wall of defense against wind driven rain and seepage due to ice damming. Ice & water is most commonly used as a continuous covering for valleys. Valley underlayment is installed before other areas for proper water lapping.
Ice & water can also be used as a complete underlayment solution (in place of felt or Titanium). This is most commonly practiced on lower pitched roof slopes as seen here.
