  • TPO Flashing provides 35% more flexibility, making it easier to field-fabricate details.
  •  Superior weldability allows for consistent, high-quality seams in penetrations and other critical roof areas
  1. TPO Flashing is used to flash various roofing system details and penetrations. The specific installation method will vary based on the situation.
  2. Use a lower temperature setting on the heat welder than when welding reinforced TPO membrane. Typically, a setting of “6” on a scale of “10” is appropriate for welding TPO Flashing.
  3. Use the edge of the roller to crease the flashing into any membrane step-offs to ensure a proper seal.
  • Sunglasses that filter out ultraviolet light are strongly recommended, as tan and white surfaces are highly reflective. Roofing technicians should dress appropriately and wear sunscreen.
  • Store TPO Flashing in a cool, shaded area and cover with light-colored, breathable, waterproof tarpaulins. TPO Flashing that has been exposed to the weather for approximately 7 days or longer must be prepared with Weathered Membrane Cleaner prior to hot air welding.
