If you said the chimney is missing a chimney cap, you’re right! Such a simple, inexpensive fix. However, if this is left like this, you could be facing one or more of the following issues:
1. Chimney caps keep out birds, BATS, squirrels, and other small rodents. If something crawls into your chimney but gets stuck and can’t get out (which happens a lot), not only is that awful for the animal, but you will also be dealing with a dead critter, bad smells, and even bugs (maggots, etc.). Yuck.
2. SAFETY ISSUE – wood burning fireplaces sometimes emit large burning embers that float up the chimney and without a cap, can land on your roof or something equally flammable.
3. Chimney caps help reduce water/moisture that can damage your chimney liner and other components and can also lead to mold.
4. A correctly placed cap can help block downdrafts and excessive wind (especially during hurricanes and other serious weather events) from channeling down your chimney and blowing smoke and/or soot into your living space. Caps also prevent debris like leaves and small branches/twigs from getting inside your chimney.
So what does all of this mean? If you’re buying a house, make sure it has a chimney cap! If you own a house with a chimney, go take a look and make sure you have one and that it is securely placed. If you can’t tell, then it’s time for a roof inspection.
