Flashers #7 Silicone High Temp Roof Jack Pipe Boot - Flexible Seal

In this review of the Flashers #7 Silicone High Temp Roof Jack, the bottom line is clear: this roof flashing is for installers and homeowners who need a durable, heat-resistant seal for metal roofing vents with pipes 6 in to 11 in outer diameter. The reviewer found the product's biggest advantage is its combination of extreme temperature tolerance and flexible silicone construction, which resists cracking and adapts to metal roof ribs without complicated tools. The fact it is 100% made in the USA and carries an IAPMO R&T listing adds confidence for code compliance.

Key Features

• Made in the USA: Manufacturer direct production by an American workforce ensures consistent quality and traceability for professional installs.
• Wide temperature range: Rated for continuous service from -100 to +450 degrees F, it stands up to extreme heat and cold without degradation.
• Flexible silicone cone: The rubberized material flexes to follow roof ribs and resists cracking, accommodating thermal expansion and pipe vibration.
• Universal base fit: A heavy rubber fold and aluminum ring at the base allow the flashing to conform to different roof pitches and metal profiles.
• Simple installation: No special tools are required and the cone is marked in inches and millimeters so it can be cut to size with tin snips or scissors.
• Code listed: IAPMO R&T Certificate of Listing indicates compliance with the Uniform Plumbing Code and International Plumbing Code for peace of mind.

Who It's For

This flashing suits professional roofing contractors and experienced DIYers working on metal roofs who need a reliable seal for vent pipes between 6 in and 11 in OD. Its heat resistance makes it appropriate for rooftop locations exposed to high temperatures near exhausts, vents, or solar gain.

It is less suitable for users who need off-the-shelf sizes outside the 6 in to 11 in range or who prefer a flashing pre-cut to a single pipe diameter; however, the clearly marked cone allows simple trimming for a tailored fit.

Pros & Cons

Pros

• Durable silicone resists cracking and handles extreme temperature cycles without failing.
• Flexible design and aluminum ring make it adaptable to varied metal roof profiles and pitches.
• Easy to customize and install with common tools thanks to clear inch and millimeter markings.

Cons

• The product covers a broad OD range and requires trimming for a snug fit rather than being pre-sized for a single pipe diameter.
