Dektite #5 Gray EPDM Metal Roof Pipe Flashing, Round Base, Pipe OD 4-1/4" - 7-1/2"

saved half from local menards using warehouse. works great

This boot works great! I put in a continuous hot water heater and it requires a 5" concentric vent. 5" boots are not readily available at Lowes or HD. I saw this on Amazon and decided to give it a try. I used a high quality clear silicone and glued it directly to the gently sloping shingled roof. It was very easy to install. After this brutally cold winter I inspected it a week ago. Absolutely no leaks and still looks great.

Good product but not for high heat.

Works great! Easy to install and you don't need to use roofing tar.

These are amazing. no question that they are the best possible flashings for metal buildings.
