Helps Create a Water-Proof Barrier

Protects against water infiltration around eaves, rakes, valleys, vents, chimneys and skylights.

Overview

WeatherLock® Flex Flexible Self-Sealing Ice & Water Barrier provides excellent roof deck protection against water infiltration resulting from the freeze/thaw cycle, wind-driven rains and normal water flow around eaves, rakes, valleys, vents, chimneys and skylights.

Engineered for asphalt shingles, wood shakes and quarry slate roof assemblies, WeatherLock® Flex also offers:

  • High performance – Flexible and pliable poly surface and modified asphalt combine to adhere around irregular shapes, inside corners and at sharp angles, even in cold-weather applications to 40ºF
  • Added protection – Acts as a waterproof barrier in the most vulnerable sections of the roof, such as valleys and other roof penetrations, to create a second line of defense. For optimal protection, apply to entire roof deck on 2:12 to 4:12 pitch roofs*
  • Aggressive self-adhesive – Exceeds adhesion performance requirements to help prevent water migration
  • Slip-resistant surface – For excellent traction and safe installation
  • Seals tight around nails – Modified asphalt construction for a tight seal around nails to prevent water penetration
WeatherLock® Flex is an essential part of the Owens Corning® Total Protection Roofing System®^.

2. The surface burning characteristics of these products have been determined in accordance with ASTM E84. This standard should be used to measure and describe the properties of materials, products or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use. Values are reported to the nearest 5 rating.
