Designed for 2″ to 7-1/4″ pipe diameters, this boot uses an aluminum base and flexible EPDM collar to create a secure waterproof seal on metal roofs. The cut-to-fit feature assists retrofit projects by matching the exact pipe OD. Durable EPDM resists UV and weather exposure, while the aluminum base conforms to metal roof panels for a tight seal.
Who it’s best for: roofers and DIYers tackling retrofit jobs where the pipe is near 2″ size and a strong, conforming base is needed. Limitation: ensure correct cutting for a precise fit and check compatibility with specific metal panels in use.

Installation follows a simple four-step process, including sealing with silicone for a watertight result.
Who it’s best for: property owners needing a versatile kit that accommodates multiple pipe sizes and roof types. Limitation: for fine tuning beyond 5-3/4″ or unusual pipe shapes, a different boot may be required.
Buying Guide: Key Considerations For Choosing A Roof Jack Flashing
- Pipe diameter compatibility: Confirm the outside diameter (OD) you need to seal. Select a boot labeled to fit your pipe OD range to avoid gaps or leaks.
- Material resilience: EPDM rubber and silicone variants provide UV, ozone, and temperature resistance. Choose based on climate exposure, whether you face extreme cold or heat.
- Base design and installation: Aluminum bases conform well to metal roofs; ensure the base provides a secure seal against wind uplift and water intrusion. Look for pre-drilled holes or adjustable clamps if you lack professional tools.
- Roof type compatibility: Metal roofs require flashing boots with flexible collars that seal tightly to panel profiles. For flat or ceramic tile roofs, confirm the boot’s adaptability and sealing method.
- Single vs. multi-pack options: If you have multiple penetrations, consider a multi-pack offering cost efficiency and consistent performance across installations.
- Replacement and retrofit suitability: Retrofit-ready boots are beneficial for renovating older installations where existing flashings show wear or cracking.
