The radon guy is going to punch a hole in my roof for the radon exhaust pipe. I am OK with this.
He told me he has a roof boot for the pipe that he can install from the inside of the attic. He doesn't have to get on the roof to install it. I have never heard of such a thing. I am really concerned something like this would leak. Have you ever seen such a thing?? What is it called so I can take a google? Thanks.
