Oatey Company 11919 Roof Flashing 1.5-3 Inch No-caulk

Product Description

The OATEY COMPANY 11919 is a no-caulk, thermoplastic base roof flashing designed to seal pipe penetrations through roofing systems. It accommodates pipe sizes from 1.5 inches through 3 inches, covering the most common residential and light commercial pipe diameters in a single flashing unit. The flexible thermoplastic base conforms to roof slopes and shingle surfaces without requiring sealant at installation, reducing labor time and the potential for application errors. Licensed plumbers and roofing contractors install this type of flashing during new construction and re-roof projects to create a weathertight seal around pipe stacks and vents.

This flashing is suited for residential and light commercial applications where pipe penetrations through the roof deck require a durable, weather-resistant seal. Typical installations include drain-waste-vent stacks, plumbing vent pipes, and similar round pipe penetrations in the 1.5-inch to 3-inch range. The no-caulk design makes it appropriate for use on standard pitched roofing systems where a clean, self-sealing fit is preferred. Each unit is sold individually, with 12 units per package for contractor stocking.

Key Features

• Fits pipe sizes of 1.5 inches, 2 inches, and 3 inches in a single flashing unit
• No-caulk installation reduces labor time and eliminates sealant application variables
• Thermoplastic base conforms to roof pitch and shingle contours
• Designed for residential and light commercial roof penetration sealing
• Sold as individual units, packaged 12 per case for contractor convenience

Compatibility

Designed as an OEM-style replacement and new-installation roof flashing for round pipe penetrations measuring 1.5 inches, 2 inches, or 3 inches in outside diameter on standard pitched roofing systems.

Installation Notes

Installation is typically performed by a licensed plumber or roofing contractor in accordance with local plumbing and building codes. The roofing surface should be clean and free of debris before seating the flashing base under the overlapping shingles. Follow all applicable IPC and local code requirements for pipe-through-roof penetrations. Do not stretch or deform the thermoplastic boot beyond the rated pipe size range, as this can compromise the weathertight seal.
