Roof Vent Pipe Repair Boot Kit for 1.5"–2" Pipe

Quick Answer

The Roof Vent Pipe Repair Boot Kit stops leaks at the base of 1.5"–2" plumbing vent pipes that exit through the roof. Made from industrial-grade thermoplastic rubber with two heavy-duty stainless steel clamps, it creates a compression-tight, weatherproof seal in about 20 minutes — no roofer, no tar, no tape.

Why It Works

Most roof vent leaks come from the rubber boot that seals the vent pipe to the roof surface. Over time, UV exposure and temperature cycles crack and harden the boot, letting water in around the pipe. This kit wraps a new thermoplastic rubber sleeve around the pipe and clamps it tight — stopping the leak at its source without removing shingles or hiring a contractor.

Key Benefits

• Stops roof vent leaks permanently — no roofer bill required
• Thermoplastic rubber — more elastic than EPDM, expands and contracts with the pipe naturally
• Two stainless steel clamps — even pressure, no single point of failure, corrosion-proof
• Fits 1.5"–2" vent pipes — standard residential plumbing vent size
• Works on asphalt shingles, wood, tile, and metal roofs
• UV and ozone resistant — built to last through extreme heat and freezing cold
• 20-minute install — 3 steps, no special tools needed

What's in the Box

• Thermoplastic rubber repair patch x1 (fits 1.5"–2" pipes)
• Heavy-duty stainless steel clamps x2
• Illustrated instruction guide x1

3-Step Installation

1. Measure — Confirm pipe diameter is 1.5" to 2"
2. Wrap — Slide rubber sleeve around pipe and press base flat over existing flashing
3. Clamp — Tighten both clamps until rubber seats firmly against the pipe

Best For

• Active roof vent leaks causing ceiling water stains
• Preventative replacement of old, hardened, or cracked rubber boots
• RV trailers and mobile homes with exposed roof vent pipes
• Homeowners who want to avoid a $300–$500+ roofer call for a simple boot replacement

What to Know Before Buying

• Fits 1.5" to 2" outer diameter vent pipes only — measure before ordering
• Clean and dry the pipe and surrounding surface before installation for best seal
• For badly deteriorated old boots, remove them completely so this kit seats directly on the metal flashing base
• Not intended for pipes larger than 2" in diameter

FAQ

Will this work on a metal roof?

Yes. The rubber base is flexible enough to conform to metal roof surfaces. Clean and dry the area thoroughly before installation for the best seal.

How long does installation take?

Most homeowners complete the repair in about 20 minutes with basic hand tools.

Is this a permanent fix?

Yes. Thermoplastic rubber is UV and ozone resistant and designed to last through years of temperature cycling, making this a long-term solution rather than a temporary patch.
