Oatey 530-11908 Roof Flashing 1-1/4 to 1-1/2 Inch Vent Pipe

Product Description

The OATEY 530-11908 is a thermoplastic roof flashing designed to create a watertight seal around plumbing vent pipe penetrations at the roofline. Sized for pipe diameters from 1-1/4 to 1-1/2 inches, the flashing slips directly over the vent stack without caulk. It automatically adjusts to both pipe diameter and roof pitch, eliminating the need for field trimming or sealant in most installations. Constructed from rigid black thermoplastic, the material resists fading and cracking over time. Plumbers and roofers install this flashing during new construction or re-roof projects to comply with code-required weathertight penetration sealing.

The 530-11908 is suited for residential and light commercial roofing applications where plumbing vent stacks pass through the roof deck. It is commonly installed on asphalt shingle, modified bitumen, and similar low-to-mid slope roof assemblies. The self-adjusting collar accommodates varying roof angles without requiring separate pitch adapters, making it a practical choice on both standard and steeper residential pitches.

Key Features

• No-caulk design slips over vent stack and self-seals without additional sealant
• Automatically adjusts to pipe size range of 1-1/4 to 1-1/2 inches and to varying roof angles
• Rigid black thermoplastic construction resists fading and cracking
• Suitable for both residential and commercial roof penetration applications
• Provides a watertight seal around plumbing vent pipe at the roofline

Compatibility

Designed for use with plumbing vent pipes in the 1-1/4 to 1-1/2 inch diameter range in residential and commercial roof penetration applications.

Installation Notes

Installation is typically performed by a licensed plumber or roofing contractor. Shut off any active work in the plumbing system before disturbing the vent stack at the roof. Slip the flashing over the pipe before final pipe connections are made where possible, and integrate the flashing base with the roofing membrane per local building code requirements. Refer to applicable IPC and local mechanical codes for vent pipe clearance and termination height above the roof surface.
