What You Get: This kit includes two complete roof collar repair boots with matching vent flashings designed to fit 1.5"-2" pipes, plus stainless steel clamps for a tight, secure seal. Installs directly over cracked or vent flashings, helping you avoid costly tear‑offs, re‑roofing, or major roof repairs. Reliable Material: Each repair boot is made from durable thermoplastic rubber that resists aging, cracking, and UV damage for long‑lasting performance. Various Application: Designed to cover round pipes between 1.5" and 2" in diameter, this flexible roof vent flashing adapts well to many roof types. The boot can be trimmed to fit and flexes to conform around pipe vents, making it ideal for waterproofing flat roofs, pitched roofs, metal roofs, or most common vent installations. Ideal for Preventative Use: Use this roof collar repair boot not only for fixing existing leaks, but also as a preventative upgrade to protect original boots and flashings from harsh weather, UV exposure, and aging. Installing it early helps extend the service life of your roofing system and reduces long‑term maintenance costs. Round Base for Enhanced Fit: The flexible, round base is engineered to contour closely to the roofing surface around your vent, improving coverage, stability, and water shedding. For a seamless installation, simply position the boot over the pipe and tighten the stainless steel clamp to create a durable, leak‑resistant seal.
