#7 Dektite Round Roof Boot - Gray EPDM

This #7 round Dektite roof boot is a flexible gray EPDM flashing for compatible pipe penetrations through metal and profiled roofing. The round aluminum-backed base can be shaped to follow roof ribs and contours while the EPDM cone is trimmed to fit the outside diameter of the pipe.

The current DEKS Original round-base #7 gray EPDM model is identified in distributor and product literature as the DF107G family. This is different from the red silicone high-temperature Dektite, which has a substantially higher temperature rating.

EPDM vs. High-Temperature Silicone

This gray boot is EPDM. It should not be treated as equivalent to a red high-temperature silicone roof boot. If the pipe surface temperature at the roofline can exceed the EPDM rating, consider the #7 High-Temperature Red Silicone Dektite Roof Boot instead, provided it is compatible with the chimney and roof system.

Always evaluate the outside surface temperature of the actual chimney or vent at the roof penetration. Exhaust-gas temperature inside the flue is not the same as the roof-boot temperature.

Fit With 4-Inch Selkirk Chimney

Our 4-inch Selkirk insulated chimney has an outside diameter of approximately 6 inches, which places it at the lower end of this #7 boot's published fit range. Verify the actual chimney outside diameter and roof layout before trimming the boot.

Compare Roof Flashing Options

A flexible Dektite can work well on many profiled metal roofs, but it is not the only flashing option. Depending on the chimney system and roof construction, you may instead need the 4-Inch Flat Roof Flashing, 4-Inch Adjustable Roof Flashing, or 4-Inch Steep Roof Flashing.

Installation Notes

Dektite installation generally involves trimming the cone to the pipe size, sliding the flashing over the pipe, applying compatible sealant beneath the flexible base, shaping the base to the roof profile, and fastening it with appropriate long-life self-sealing fasteners. Follow the current DEKS instructions and the roofing manufacturer's requirements for the exact installation method.

Roof pitch, roofing material, pipe temperature, chimney listing, and local code all affect whether this EPDM boot is appropriate. Do not substitute a flexible boot for a chimney manufacturer's required flashing component unless the installation allows it.
