ACNOYEL #6 Epdm Roof Jack For Metal Roof
The ACNOYEL roof jack is designed for corrugated metal roofs with a flexible EPDM sleeve and an aluminum base. It supports pipe outer diameters from 4 3/4″ to 10″, making it suitable for common residential venting and exhaust configurations. The dual-material construction helps maintain shape and seal across extreme temperatures, from -65°F to 250°F, while the square base aids stable installation on varying roof profiles. This model emphasizes compatibility with corrugated roofing styles and offers a straightforward sizing approach by sleeve adjustment.
Flashers Black EPDM Roof Jack – 1/4″ to 5″ OD
Manufactured in the USA, this Flashers roof jack uses EPDM to provide a flexible, durable seal around pipes from 1/4″ up to 5″ in outer diameter. The product is rated for a broad temperature range and emphasizes domestic production, which some installers prefer for compatibility and supply chain certainty. While compact, its sealing sleeve can be trimmed to tailor the fit for smaller penetrations, delivering a practical option for smaller vent or pipe penetrations on metal roofs.
ACNOYEL Metal Roof Vents Flashing Kit – 1/4″ to 5-3/4″ OD
This kit from ACNOYEL targets corrugated roofs with a versatile EPDM flashing boot that accommodates pipes from 1/4″ to 5-3/4″ OD. The packaging often includes roofing screws and hex tools to streamline installation, reducing the number of separate components a installer needs to source. The combination of EPDM sleeve and aluminum base helps maintain a seal across temperature extremes, making it a solid option for varied climates and roofing layouts.
Yaocom Roof Boot Flashing for 7″–13″ Pipes
Yaocom’s roof boot provides a cone-shaped, square-based flashing designed for larger pipe penetrations, with a recommended range from about 6 3/4″ to 13-1/2″ OD. The kit emphasizes material robustness with EPDM and aluminum components and is sold as a single-piece unit. This option is particularly suitable for chimney or large-diameter vent penetrations on metal roofs where a broad fit is needed without extensive on-site modifications.
ACNOYEL Epdm Roof Jack – 6 3/4″ to 15″ OD
This larger-capacity roof jack provides a generous fitting range from 6 3/4″ to 15″ OD, aiming to cover oversized penetrations common in multi-vent configurations or tall chimney setups on metal roofs. The construction uses EPDM for the sleeve and an aluminum base for structural support, enabling reliable performance in extreme temperatures. The broad size range reduces the need to stock multiple intermediate fittings.
Flashers #2 Black EPDM Roof Jack – 1-3/4″ to 3-1/4″ OD
Flashers offers a mid-range option for pipes between 1-3/4″ and 3-1/4″ OD with EPDM construction and domestic manufacturing. This size range suits common bathroom vent pipes or smaller attic vent penetrations on metal roofing. The kit’s American craftsmanship is highlighted, aligning with installers seeking reliable American-made components and consistent performance across a broad temperature spectrum.
Buying Guide
Key considerations when selecting a roof jack for metal roofs include: fit range, material quality, and installation ease. Look for EPDM sleeves that resist aging from UV exposure and temperature shifts, with an aluminum base that provides rigidity without rust. Ensure the outer diameter range matches the pipe or vent you intend to seal, and verify whether the product includes installation hardware such as screws or hex keys to minimize extra purchases. For corrugated metal roofs, a square or flat base helps distribute load and maintain a stable seal against wind uplift. If your project involves large penetrations, choose a jack with a wider OD range and confirm compatibility with existing flashing and sealants. Consider local climate conditions, as temperatures below freezing or high heat can affect rubber elasticity; select products rated for the expected operating environment. Finally, assess whether you need a single-piece flashing or a kit that includes related fasteners and tools, which can streamline installation and reduce mismatch risk.
Product diversity offers options for small-diameter penetrations, mid-range vents, and large chimney or pipe installations on metal roofs. Each listed product emphasizes durable EPDM material, aluminum reinforcement, and temperature resilience, making them suitable for American homes with varied climates. When in doubt, measure the actual outside diameter of the pipe or vent and choose a sleeve size that ensures a snug, leak-free seal. Additionally, consider the ease of trimming sleeves to fit non-standard sizes without compromising the integrity of the seal.
