OATEY 11877 Roof Vent Flashing
The OATEY 11877 is a steel roof vent flashing designed for pipe vents on pitched roofs. It fits pipe diameters from 3 inches to 4 inches and uses a rubber collar for sealing. The rectangular base measures 15 inches by 12 inches and is made from 28-gauge steel. It meets IAPMO UPC and NES 653 standards.
Suited for residential roof penetrations
This flashing suits installers sealing a single pipe vent on a pitched roof with a 40-degree angle. The all-flash no-calk design simplifies installation without separate sealant. Builders needing to flash multiple pipes, flat roofs, or pipe sizes outside the 3-to-4-inch range should look at other products. It is not intended for non-roof applications.
Handles 3-to-4-inch pipes on 40-degree slopes
The unit comfortably handles one pipe vent within the stated diameter range on the specified roof pitch. UV-protected rubber materials resist weather degradation over time. Headroom runs out when the roof angle differs significantly from 40 degrees or when the pipe diameter exceeds 4 inches. The fixed base dimensions also limit flexibility for non-standard openings.
