Oatey OATEY11871 All-flash No-calk Roof Flashing Aluminum 1-1/2 to 3 Inch Pipe 11 X 14-1/2 Inch Base

Product Description

The Oatey OATEY11871 All-Flash No-Calk Roof Flashing is a durable aluminum flashing designed to create a watertight seal around pipes that penetrate through a roof surface. Built for professional plumbers, roofers, and contractors, this flashing fits pipe sizes ranging from 1-1/2 inches to 3 inches in diameter, making it a versatile solution for a wide range of residential and commercial applications. The base measures 11 inches wide by 14-1/2 inches long, providing ample coverage to overlap roofing materials and prevent water intrusion. The galvanized finish adds an extra layer of corrosion resistance, helping the flashing hold up against rain, UV exposure, and temperature fluctuations over time. Aluminum construction keeps the unit lightweight without sacrificing structural integrity, and the no-calk design eliminates the need for additional sealants during installation. This means fewer materials on the job and faster install times for field technicians. The formed aluminum collar fits snugly around the pipe and can be adjusted to accommodate the slope of the roof, ensuring a proper weather-tight fit on pitched surfaces. Roof pipe flashings like this one are critical components in any plumbing rough-in where a vent stack, drain line, or soil pipe exits through the roof deck. Without proper flashing, water can infiltrate the roof penetration point and cause structural damage, mold growth, and costly repairs. The Oatey All-Flash No-Calk design is a trusted standard in the trade for good reason: it installs quickly, seals reliably, and is built to last through years of outdoor exposure. Compatible with asphalt shingles and many other common roofing materials, this flashing is a go-to choice for vent pipe roof penetrations on new construction and replacement projects alike.

• Fits pipe sizes from 1-1/2 inches to 3 inches in diameter for versatile application coverage
