Silicone Roof Pipe Boot – Flexible Waterproof Vent Cover

Silicone Roof Pipe Boot – Flexible Waterproof Vent Pipe Cover

Keep your roof watertight with this heavy-duty Silicone Roof Pipe Boot. Engineered from premium silicone rubber, this flexible flashing boot forms a secure, weather-resistant seal around vent pipes, exhaust pipes, and other roof penetrations — making it a go-to solution for both professional roofers and confident DIYers.

Key Features

• Flexible Stepped Cone Design: The multi-step cone can be trimmed to match pipe diameters from approximately 2-3/4 in to 7 in, allowing a snug, customised fit around virtually any vent or exhaust pipe.
• Wide-Range Temperature Resistance: Rated for environments from approximately -165.2°F to 446°F (-110°C to 230°C), this boot maintains a stable, reliable seal in both extreme cold and intense heat.
• Metal & Corrugated Roof Compatible: The square base (approx. 250 × 250 mm / 9.84 × 9.84 in) is specifically designed to lay flat and fasten securely on metal corrugated roofs and pitched roofs, maximising the contact area for a leak-free install.
• Durable Silicone Rubber Construction: Unlike EPDM or plastic alternatives, silicone rubber stays flexible year-round without cracking, shrinking, or hardening — even after prolonged UV and weather exposure.
• Easy Installation: Simply cut the stepped cone to your required pipe diameter, slide over the pipe, press the base flat against the roof surface, and fasten around the edges. No special tools required.

Installation Tips

1. Identify the outer diameter of your roof pipe before cutting the stepped cone.
2. Cut from the top of the cone downward, one step at a time, until the opening matches your pipe size.

Frequently Asked Questions

Q: What pipe diameters is the Silicone Roof Pipe Boot compatible with?

A: This silicone pipe boot is designed to fit pipe diameters from approximately 2-3/4 inches up to 7 inches. The stepped cone construction allows you to cut it to the exact diameter you need, ensuring a tight, custom fit around your specific vent or exhaust pipe.

Q: Can this roof pipe boot handle extreme temperatures?

A: Yes. The silicone rubber material is rated for a wide temperature range of approximately -165.2°F to 446°F (-110°C to 230°C), making it suitable for use in both very cold climates and high-heat environments such as near furnace exhaust or solar-heated metal roofs.

Q: Is this boot suitable for corrugated metal roofs?

A: Absolutely. The wide square base (approx. 250 × 250 mm) is specifically engineered to sit flat and seal effectively on metal corrugated and pitched roof surfaces, providing maximum contact area and a secure, weatherproof seal around roof penetrations.

Q: How do I cut the silicone boot to fit my pipe?

A: Measure your pipe's outer diameter first, then use a sharp utility knife to cut the stepped cone from the top opening downward, removing one ring at a time until the opening matches your pipe size. Always cut slightly smaller than your pipe diameter and stretch the silicone for a snug, watertight seal.
