Shadowlastic™ Plus Roof Flashing Tape Black/White Printed 627-35 4IN x 50FT 35 Mil | Waterproof Adhesive Tape

Polyken 627-35 Foilastic® Roof Flashing Tape is a high-performance sealing solution engineered for a wide range of roofing and exterior repair applications. Ideal for flashing details on concrete tile roofs, it delivers a dependable seal for critical areas such as roof ridges, hips, penetrations, gutters, valleys, eaves, chimneys, vents, and rooftop duct systems. It is also well-suited for sealing deck-to-wall transitions and repairing sheet metal surfaces on mobile homes and trailers, helping prevent air and water infiltration.

Constructed with a durable woven polyethylene backing, this tape offers excellent flexibility and conformability for complex surfaces while maintaining long-lasting strength. Its butyl rubber adhesive forms a permanent, weather-tight bond on clean, dry substrates and performs reliably across a wide range of temperatures. Designed for extended outdoor use, it provides up to 3 years of UV resistance. The tape is compatible with most sealants and caulking products, features self-healing properties after minor punctures, and can contribute toward energy efficiency goals when used in building envelope systems.
