VIVIDA #8 Silicone Metal Roof Pipe Flashing - Flexible High Temp Roof

In this review the VIVIDA #8 Silicone Metal Roof Pipe Flashing is evaluated for installers and homeowners who need a durable, flexible solution for sealing large roof pipes on corrugated metal roofs. The bottom line: this roof jack is best for people who work with 7' to 13' outside-diameter pipes and need a pliable, high-temperature silicone boot that can be molded to ribbed metal panels; the built-in square base and included fasteners simplify installation and reduce trips to the hardware store.

Key Features

• Size compatibility: Designed for pipe OD 7in to 13in, the #8 silicone boot covers a wide range of vent and chimney sizes for flexibility on site.
• Flexible square base: The square base can be molded to corrugated metal ribs and works well on 10/12 to 12/12 roof pitches for a better seal.
• High temperature tolerance: Made from high temp silicone rubber that performs across a broad range from -165.2F to 446F, suitable for many exhaust and stove vent applications.
• Easy installation: Package includes thirty #10 x 1-1/2in roofing screws and an 8mm hex bit socket so installers have the basic hardware needed to fasten the flashing.
• Cut-to-fit boot: The silicone cone can be trimmed to match pipe diameter, allowing a snug fit without needing multiple different boots.

Who It's For

The VIVIDA #8 flashing is ideal for roofing contractors, DIY homeowners, and remodelers working with corrugated metal roofs who need a single boot to cover medium to large diameter pipes, chimneys, or exhausts. Its pliable square base makes it especially useful where roof ribs vary and where a snug, molded fit is required.

It is less suited for very deep corrugated panels over 1.5in or for installations where pipe OD falls well outside the 7in to 13in range; in those cases choosing a different size or a boot designed for extreme corrugation depth is recommended.

Pros & Cons

Pros

• Wide 7in to 13in pipe coverage reduces the need to stock multiple sizes.
• High temp silicone provides reliable sealing for exhaust and stove vent applications.
• Includes 30 roofing screws and a hex socket so the kit is ready to install.
• Flexible square base conforms to corrugated metal ribs for a better fit.

Cons

• Not recommended for deep corrugated panels over 1.5in without selecting a larger size.
• Performance depends on staying within the specified temperature range; extreme heat exposure can cause failure.
