Caps & Guards

Does my chimney need a chimney cap?

Absolutely. There are many reasons why a chimney cap should be present on all chimneys.  The primary function of a chimney cap is to keep animals and weather out. Leaving your chimney without a chimney cap leaves your chimney and masonry susceptible to water damage, increased possibility of a roof fire, not to mention critters getting in.

Here are a few reasons to make sure your chimney has a cap:

Prevents Weatherchimney caps keep rain and animals out

A chimney cap stops rain, snow and downdrafts from entering the chimney. Rain and snow which enters the flue can cause an internal damper and parts of your firebox to rust which could lead to expensive repairs. The chimney cap will also keep water away from sensitive parts of the chimney crown and flue area. When water enters any small gaps and then freezes, the water expands which can crack or damage the mortar or bricks. When water finds its way down to the mortar joints of your clay flue tiles, it may crack the mortar joints or completely push them out, which means a potential chimney reline. Many chimneys without caps can experience downdrafts, or wind coming down the chimney. There are some models of chimney caps which can actually induce an updraft, which are very helpful for areas prone to downdrafts.

Prevents Birds & Pests

A proper chimney cap will not allow birds, bats, squirrels, raccoons or other animals to enter the chimney. This may not seem like a big deal, but you would be surprised how often we see critters in chimneys. There is also a possibility you could end up with a protected species nesting in your chimney, like Chimney Swifts. If these guys get in your chimney, their nests and young can not be disturbed while it is breeding season. While this might not seem like a big deal, Chimney swifts can be quite loud and disrupt your peace and quiet.

Fire Prevention

A proper chimney caps will include wire mesh or some other mechanism to help prevent ash and sparks from being blown onto rooftops and the ground outside of your home. Even the smallest spark can start a fire under the right conditions, and given the price of a chimney cap is so low when you consider its life span, it is an easy decision to make.

Quality Chimney Caps

Not all chimney caps are created equally. Chimney Works deals in quality, stainless steel chimney caps, many with a long warranty. Proper installation is crucial, as chimney caps that fly off during storms can cause damage to your roof or elsewhere on the home. If a regular chimney cap does not fit your flue or isn’t right for the application, Chimney Works can recommend specialty caps. Some caps can even lower your heating bill.
