Most homes are equipped with chimneys, but that doesn't mean all homeowners understand their inner workings. One of the main points of confusion is the difference between a chimney cap and a cover. Absolute Chimney Service, based in Kennebunkport, ME, explains the key differences between these oft-confused components.

Here’s their simple guide:

• Material: Chimney caps, which cover the top of your flue, are most often made of metals, such as stainless steel or copper, and have mesh siding. Covers, on the other hand, are often made of masonry to match the chimney itself. 
• Function: The chimney cap has open mesh sides to allow smoke and exhaust fumes to escape easily. They serve other purposes, too, including protecting the chimney joints from rainwater and pest intrusions. Chimney covers serve a similar purpose, though they do not necessarily have the exhaust-releasing capability. They primarily serve to protect the top of the chimney from the elements. 
• Location: Although chimney caps and covers are both found on top of a home's chimney, their installation is slightly different. Chimney caps are attached on top of the flue, while covers go directly on top of the chimney itself.
