Flashers #5 Black EPDM Flexible Roof Jack Pipe Boot - Durable Seal

In this review the Flashers #5 Black EPDM Flexible Roof Jack pipe boot is assessed for roofers and homeowners who need a reliable, easy-to-fit flashing for metal roofs. The main reason to buy is its combination of flexible EPDM rubber and an aluminum base that adapts to roof pitch and metal profiles, providing a durable, weather-resistant seal that installers say stays leak-free over time. For anyone fitting pipes 4-1/4' to 7-1/2' outer diameter, this product promises a straightforward installation and long-term service across extreme temperatures.

Key Features

• Made in the USA: Manufacturer direct production ensures consistent build quality and supports an American workforce for traceable sourcing.
• Wide temperature rating: EPDM material is rated from -65 to +250 degrees Fahrenheit, which makes it suitable for extreme cold and hot climates without cracking.
• Flexible fit: The rubber cone flexes to accommodate expansion, contraction and pipe vibration while maintaining a reliable seal against leaks.
• Aluminum base and heavy rubber fold: The combination allows the flashing to conform to any roof pitch or metal profile for a flush, visually neat installation.
• Simple installation: No special tools are required and the cone is clearly marked in inches and millimeters so it can be trimmed with tin snips or scissors.
• Code compliance: Holds a Certificate of Listing with IAPMO R&T, indicating compliance with UPC and IPC plumbing codes.

Who It's For

The Flashers #5 is best suited for professional roofers, metal roofing installers and handy homeowners who need a robust pipe boot for medium to large diameter pipes between 4-1/4' and 7-1/2' OD. Its durability and wide temperature tolerance make it a strong choice for regions with heavy weather variation, and the aluminum base is particularly useful on standing seam and corrugated metal roofs.

Those who should look elsewhere include buyers needing boots for much smaller pipe diameters or specialized roof systems that require an integrated flashing kit. If a project demands an adhesive-backed or custom-molded flashing for nonstandard materials, a different product may be more appropriate.

Pros & Cons

Pros

• Easy to trim and install with common cutting tools, saving time on the roof.
