#7 Metal Roof Pipe Flashing Boot - High Temp Silicone Chimney Boot

In this review the focus is on the #7 metal roof pipe flashing boot, a straightforward solution for sealing stove pipes and chimneys on metal roofs. The bottom line: this product is best for homeowners or contractors who need a durable, heat-resistant flashing that fits pipe diameters from 6' to 11' and can be trimmed to size. It stands out for combining a stable metal base with a high temperature silicone rubber sleeve that resists from -100F to 450F, which makes it a practical choice where temperature range and reliable sealing are the main concerns.

Key Features

• Metal base fit: The metal flashing base is sized to accommodate pipe diameters between 6' and 11', delivering a sturdy roof connection for standard stove pipes.
• Trim-to-fit sleeve: The rubber sealing sleeve can be cut to the exact pipe diameter needed, allowing a tailored seal without custom parts.
• Wide temperature rating: Rated to operate from -100F to 450F, the materials help protect the chimney and maintain sealing across extreme conditions.
• Water and snow protection: The combined metal and rubber construction provides excellent sealing performance to reduce the risk of leaks during rain or snow.
• Flexible adaptation: The relatively soft metal offers enough rigidity for stability while still allowing the flashing to conform to roof contours.
• Cost-effective maintenance: Using a single, durable flashing unit reduces the need for frequent replacements or repairs, cutting long-term costs.

Who It's For

This flashing boot is ideal for DIY homeowners, roofing contractors, and anyone installing or repairing metal roof vents and stove pipe penetrations who require a heat-resistant, cut-to-size solution. Its broad temperature tolerance makes it suitable for both cold-climate homes and locations with high stove or chimney temperatures.

Those who should look elsewhere include buyers needing a decorative or painted finish matched to roof color, or users who require a flashing for pipes outside the stated 6' to 11' range. Also consider specialized chimney systems that mandate manufacturer-specific flashing components.
