WIP 100 is a 55-mil flexible rubberized asphalt, fiberglass-reinforced membrane used as a shingle underlayment on critical roof areas such as eaves, ridges, valleys, dormers and skylights. WIP 100 underlayment protects roofing structures and interior spaces from water penetration caused by wind-driven rain and ice dams and may also be used as covering for the entire roof to prevent moisture or water entry.

• Protects the roof structure from water seepage caused by ice dams and wind-driven rains
• Seals around roofing nails, staples and screws
• Ensures the watertightness of the primary roofing system in critical areas
• Split-release film provides easier, faster installation
• Unique granular skid-resistant surface for safe and easy installation
• Resists cracking, drying and rotting, providing long-term waterproofing performance and low lifecycle cost
• Concealed waterproofing system will not detract from the architectural aesthetics of the primary roofing system
