Metal Roof Vent Boot Flashing for 7ft to 13ft Pipes - Durable Roof

In this review of the Metal Roof Vent Boot Flashing kit, the reviewer finds it best suited for homeowners and DIY roofers who need a flexible, weatherproof seal for large vent pipes or small chimneys. The single biggest reason to buy is its adaptable cone design and quality EPDM/aluminum construction, which lets a user cut the boot to fit pipe diameters from about 6-3/4' to 13-1/2' while keeping a neat, durable seal on standing seam and metal roofs. This review focuses on practical installation use and material reliability rather than bundled hardware.

Key Features

• Generous package: Includes one roof jack so you have a full replacement unit or a spare part available for future adjustments.
• Versatile sizing: Cone shaped boot can be trimmed to fit pipe OD from roughly 6-3/4' to 13-1/2', allowing accurate field cuts for many vent applications.
• Durable materials: EPDM main body combined with a silver aluminum square base resists weathering and maintains a tidy roof appearance.
• Square 17 x 17 base: A 17 x 17 in square base simplifies flashing alignment and provides broad coverage over roof seams or fasteners.
• Moderate pitch tolerance: The compact boot accepts up to about a 45 degree pipe tilt, which covers most common roof installations.
• User-friendly fit: The cone shape and flexible EPDM allow the jack to slide over pipes for a secure seal without complex shaping.

Who It's For

This roof vent pipe boot is ideal for homeowners, contractors, and DIYers working on metal roofs who need a single, reliable flashing for ventilation pipes, stove pipes, or chimneys with large diameters. Its trim-to-fit design makes it useful where pipe sizes vary or where a spare flashing is needed for maintenance.

It is less suited for projects that require included installation hardware or for those who need a pre-cut, exact-size boot for very small-diameter pipes; buyers who need screws, sealants, or metal adapters should plan to purchase those separately.

Pros & Cons

Pros

• Flexible EPDM material forms a tight seal after trimming to the exact pipe OD.
• Aluminum square base offers a neat, corrosion-resistant mounting surface for metal roofs.
• Single-piece kit is convenient as a replacement or spare for roof maintenance.

Cons

• Package contains only the roof flashing and does not include installation hardware or sealant.
• Maximum pipe tilt of about 45 degrees may limit use on extremely steep or unusual roof geometries.

Our Verdict

The Metal Roof Vent Boot Flashing is a practical, value-minded choice for anyone needing a durable, trim-to-fit flashing for large vent pipes on metal roofs. With its EPDM body and aluminum base it offers a reliable weather seal and neat appearance, but buyers should budget separately for fasteners and sealant. For routine roof repairs and DIY installations it represents solid value.
