One thing many people overlook when chimney building involves installing a cap. A chimney cap is more than just decorative; it provides your chimney with a great deal of protection in more ways than one. Here are some problems you could face by failing to install a chimney cap.

Water Damage 
Using a chimney without a cap is just like having a 12-inch square hole in the middle of your roof. Water will eventually enter your chimney, where it will seep into the mortar and cause it to erode away over time.

The effects of water damage are long lasting, as moisture inside your chimney cannot easily evaporate. There is little air circulation, which means that any water that does get into your chimney is likely to stay there for some time. If the water is allowed to freeze and then thaw again, it can cause considerable damage.

Metal chimney liners will do little to prevent moisture damage. In fact, they too can become damaged whenever water mixes with creosote, resulting in an acid that can eventually corrode the metal.

Animal Damage 
The right cap will prevent animals and birds from nesting inside your chimney, which is something that may not be apparent until after you have started a fire. Materials used to build nests are highly flammable, and can easily catch afire, causing your entire roof to quickly become engulfed.

Leaves and Debris
Even if animals do not enter your chimney, it can nonetheless become clogged with leaves or other debris. This would essentially cause the same problem as if animals were to nest inside it. Leaves also tend to hold a great deal of moisture, and would therefore increase the effects of water damage.

As you can see, there are plenty of good reasons to have a chimney cap installed. For help with choosing or installing the right cap, please contact us – we’re happy to help!
