Hi experts,
I have a gas fireplace that was re-ducted through a patio addition that was put on my home nearly 10 years ago. The original vent was re-worked and it was extended maybe 20-30 inches through the new patio soffit and a chimney installed.
Water is pooling under the chimney and destroying the soffit but only seems to happen after we get a heavy snow and it sits on the roof for a while without melting.
The roofing company said that this is due to the duct being in a cold space and condensation forming on the pipe and dripping... typically when there is a lot of snow on the roof creating an insulating barrier for the space and creating an ideal scenario for condensation to take place. Roofing company recommended using appropriate insulator around the pipe, especially at the elbow to stop it from condensing and dripping into the patio cover.
I've talked to a few HVAC companies and they don't want to touch this and wrap the pipe so it looks like I might have no other choice than to do it myself.
Can anyone tell me what kind of product is appropriate and safe to use for this application?
Thanks.
