The Perma-Boot PBR 312-3n1 is a one-piece TPO plastic roof pipe flashing boot engineered to seal and protect vent pipes that penetrate your roof. Leaks around roof penetrations are among the most common roofing problems homeowners and contractors face. This versatile flashing eliminates guesswork by accommodating three standard pipe sizes in a single product, making it ideal for repair work, maintenance, or new construction where you need a reliable, durable seal.
Unlike traditional flashings that require exact size matching, the Perma-Boot design adapts to 1-1/2 inch, 2 inch, and 3 inch pipes, reducing the need for multiple boots on hand and simplifying the repair process. The TPO plastic construction is built to survive harsh roofing environments without corroding. Whether you’re a professional roofer or a homeowner tackling maintenance, this boot delivers a dependable solution to one of the most troublesome leak sources.
