Chimney caps and chimney crowns. Many people think these terms are interchangeable, but they aren’t. The chimney crown is actually part of your chimney. It sits at the very top, is made of mortar, and is specially designed to slope down and overhang the chimney by several inches so that precipitation is directed away from your chimney opening and onto the roof instead, where it can travel towards the rain gutter instead of towards the joint where your chimney meets the roof. A chimney cap is a piece that you can add to sit on top of the chimney crown. It’s designed like a little roof with open, mesh-covered sides, and it does the job of covering the chimney opening while allowing airflow to get into and out of your chimney. The mesh sides also serve the purpose of keeping leaves, twigs, blowing debris, and animals and birds out of the chimney. But there’s another term that you may not be quite as familiar with, and that’s a chase cover.
If you have a prefabricated or factory-built chimney, chances are you also have a chase cover. The chase is the area around the metal flue pipes, and the chase cover is made to fit over this area. It is most usually made of galvanized or stainless steel or even aluminum. Unfortunately, if your chase cover was made from a cheaper metal, chances are over time it will wear or rust out and this can mean major problems for the homeowner. Because the main purpose of a chase cover is to prevent water from entering the chase, it’s pretty clear that if it fails, you will be facing major water damage and leaks.
Signs of Trouble
One sign that you might have a problem is rust. If you can see rust on the actual chase cover or running down the chase, it’s a pretty good signal that you need to have the chase cover replaced. In severe cases, you may even see rust running down the sides of the chimney; if this is the case, call Firesafe Chimney Service soon so we can come out and replace your chase right away, before further precipitation falls and causes even more problems.
If you notice pooling water on top of your chase cover or inside your fireplace, it’s a good possibility that it wasn’t installed properly in the first place Your chase cover needs to fit properly and also have a good slope, so that water is directed away from the chase and even from the chimney itself.
