DuraVent DirectVent Pro Universal Rubber Boot Flashing Kit: a rubber seal for corrugated metal roofs
The DuraVent DirectVent Pro Universal Rubber Boot Flashing Kit is a weatherproof covering for a vent opening in a corrugated metal roof. Its flexible base seals around roof ridges where flat metal flashing cannot. The black rubber cone sits on a 23 by 23 inch base. One kit fits both 4 by 6 5/8 inch and 5 by 8 inch vents on roofs from flat to 12 in 12. DirectVent Pro is DuraVent’s pipe inside a pipe vent for direct vent gas fireplaces and stoves: exhaust goes out through the inner pipe and outside air comes in through the outer pipe.
The kit includes spacers and a ventilated shield to keep the rubber away from the hot pipe, plus a mesh screen, storm collar, and hardware. The storm collar seals above the boot with non hardening sealant at the pipe. You can paint the rubber with acrylic paint to match your roof. DirectVent Pro is tested and listed with the gas appliance, so appliance approval matters. Prefer formable metal? See the DuraVent DirectVent Pro Dead Soft Aluminum Flashing for metal or tile roofs. The DuraVent DirectVent Pro Universal Rubber Boot Flashing Kit ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

FAQ
What is the Universal Rubber Boot Flashing Kit for?
It weatherproofs a vent that passes through a corrugated or metal roof, where a flat metal flashing cannot seal. The kit has a 23 by 23 inch black EPDM rubber boot with a cone and base, a spacer kit, a ventilation shield, a mesh screen, a special storm collar and the mounting hardware, and it fits roof pitches up to 12/12.
Which vent sizes does it fit?
It fits 4 x 6-5/8 and 5 x 8 inch DirectVent Pro, so one kit covers both direct vent sizes; the spacer kit and shield set the boot off the hot pipe. The store also lists it under DuraTech 5 to 8 inch chimney, where DuraVent publishes a separate rubber-boot sales sheet, so check that sheet for the DuraTech diameters.
Is a rubber boot safe on a hot vent?
The kit is tested and certified to UL 103 Type HT, and the ventilation shield and spacers keep the EPDM off the pipe wall so the boot only touches the cooler outer shell. Install the pieces exactly as the kit instructions show; the boot is not a substitute for the vent’s clearance to combustibles inside the roof.
Can I paint the boot to match the roof?
Yes. The black EPDM cone and base can be painted with any acrylic paint to match the roof color. Trim the cone to the pipe size, seat the base on the corrugations with the hardware supplied and finish with the special storm collar above it, sealing the collar to the pipe.
Do I still need a storm collar and a standard flashing?
The kit includes its own storm collar, and it replaces the adjustable metal flashing on that roof type, so nothing else is needed at the penetration. The rest of the vertical run, pipe, firestops, attic shield and the vertical cap, comes from the DirectVent Pro category as usual.
