Oatey Company 11899 Thermoplastic Roof Flashing 2 Inches

Product Description

The OATEY COMPANY 11899 is a 2-inch thermoplastic no-calk roof flashing designed to create a watertight seal around vent stack penetrations through roofing surfaces. Built in a single-piece construction, it eliminates the need for caulking compounds during installation, reducing labor time and the potential for improper sealing. The double-seal design provides a leak-free fit that conforms tightly around the vent pipe, protecting the roof deck from water infiltration. Licensed plumbers and roofers install this type of flashing as a code-required component wherever a drain-waste-vent pipe exits through a roof.

This flashing is suited for residential and light commercial plumbing vent applications. It fits all common pipe types found in the field, including cast iron, copper, plastic, and galvanized pipe. The thermoplastic material is flexible enough to conform to varying roof pitches and pipe configurations. It meets UPC, SBC, and BOCA code requirements, making it appropriate for jurisdictions operating under those plumbing and building codes. Each unit is sold individually, with a package quantity of 6 per case.

Installation Notes

Installation is typically performed by a licensed plumber or roofing contractor during new construction or re-roofing. The vent pipe and surrounding roof surface should be clean and dry before positioning the flashing. No caulk or additional sealant is required for a proper seal with this no-calk design. Always follow local plumbing and building code requirements, and coordinate with roofing work to ensure the flashing is properly integrated into the roofing membrane or shingles.
