Oatey Company 11880 Galvanized Roof Flashing 4 Inch

Product Description

The OATEY COMPANY 11880 is a 4-inch galvanized roof flashing designed for pipe penetrations through sloped roofing assemblies. Formed from 24-gauge deep-drawing steel with a full galvanized finish, it delivers corrosion resistance suited to outdoor exposure. The extra-high collar design accommodates steeper roof pitches and helps keep water away from the pipe opening. A no-calk, no-seam construction eliminates the need for field-applied sealant at the flashing joint, reducing installation steps and potential leak points. Plumbers, roofers, and HVAC technicians install this flashing during rough-in or during re-roofing when replacing deteriorated existing flashings.

This flashing is suited for residential and light commercial applications where a 4-inch vent pipe or stack exits through a shingled or similar sloped roof surface. The no-calk design is particularly useful on new construction where a clean, code-compliant penetration is required without additional sealing materials. It meets UPC, SBC, and BOCA code requirements, making it acceptable across a wide range of jurisdictions. Units are sold individually; the supplier packages six units per carton.

Key Features

• 4-inch pipe opening fits standard 4-inch vent stacks and drain pipes
• 24-gauge deep-drawing steel construction for durability and formability
• Full galvanized finish for corrosion resistance in outdoor rooftop exposure
• Extra-high collar design accommodates steeper roof pitches
• No-seam, no-calk design reduces installation steps and potential leak paths

Compatibility

Designed as an OEM-style replacement or new-construction flashing for 4-inch pipe penetrations on residential and light commercial sloped roofing systems where UPC, SBC, or BOCA code compliance is required.

Installation Notes

Installation is typically performed by a licensed plumber or journeyman roofer during rough-in or re-roofing. Slide the flashing over the pipe before the upper course of roofing material is laid, and integrate it with the roofing material per standard flashing practice. No caulk is required at the flashing collar joint by design, though local inspectors may require additional sealing at the roofing material interface per applicable code. Follow IFGC and UPC requirements for vent termination clearances and pitch when installing gas-vent applications.
