How to Secure Chimney Caps in Windy Areas | Flue Guru

So here’s one of these, basically, fairly reasonably priced chimney caps. They’re made of aluminum and they always blow away, usually the top blows off. So what we do is we put a sheet metal screw into the tab there. You can see it down below on the tab here, we put the sheet metal screw in, and a couple more on the top and on the other side. And to keep it from blowing out of the flue, drill a little hole into the flue, in a couple of spots, and tie it down. We also silicone it in a little bit in the corners. You have to dry that off to get that done. So how to make these, these kind of caps stay on. We’ve learned this from bitter experience because we’ve had the, put one, we put a couple caps on one day, and the next morning, overnight, there was a big, big gale and the tops blew off of both of them, so now we don’t take any chances. We screw them on and that’s it. Closed Captioning by Kris Brandhagen. [email protected]
