Oatey 11899 Thermoplastic No-calk Roof Flashing, 1-pc., 2 In.

The Oatey 11899 Thermoplastic No-Calk Roof Flashing is a one-piece roof penetration solution designed for both commercial and residential applications requiring a watertight seal around plumbing vent pipes. This flashing slides over standard vent pipes to create a tight, leak-free seal that protects your roof from water intrusion at a critical penetration point.

Built from rigid black thermoplastic with a non-fading sealing collar, this flashing resists cracking and fading to maintain its integrity for years. The adjustable pitch design accommodates many different roof configurations. Its one-piece solid construction eliminates the need for caulking while providing reliable waterproofing around vent pipe penetrations.
