Roof flashings and possible leaks
In this video, Guy is up on the roof to show two different roof flashings that might be the cause of leaks in your home.
First, we see a plumbing exhaust pipe which runs through this particular house's plumbing and sewer system. There's one noticeable problem with this exhaust pipe: the top has fallen off. Squirrels can be especially pesky culprits for messing with these types of pipes. Guy explains why in the video.
