While this winter has not been too wet, many are predicting some rain over the next couple months. We don’t anticipate it reaching last year’s levels, but it’s still important that you waterproof your chimney. Water can seep into a chimney and leaks may form. But how does this potentially expensive problem even happen?
What causes chimney leaks?
Chimneys are beautiful, complex structures. The simplistic bricks or stucco columns are filled with a machine of moving parts and instruments to keep you safe and warm. It is also regularly exposed to nature’s elements. Thus, the likelihood of damage occurring and leaks forming is quite possible. However, with all of the nuances of a chimney, it can often be challenging to find the leak. The following are three of the most common sources for chimney leaks.
This piece covers the top of the flue. It covers the flue and fireplace so water, animals, and debris do not go in. Should the cap be damaged or missing, this leaves most areas of the fireplace exposed. Thus, a rain shower could cause substantial water damage.
Around the chimney and roofline, there is flashing to protect the area against water. Over time, flashing may lose its seal or it could have been improperly installed. Similar to the cap, damaged or missing flashing may dramatically damage your chimney. However, the lack of proper flashing could also harm walls, ceilings, and structures.
As you can already tell, water can be very harmful. Bricks are no exception. Water can have a dramatic impact on masonry around chimneys. This can lead to cracks and bricks falling apart. The problem can then get exponentially worse. Damaged bricks absorb greater amounts of water, leading to further harm.
Numerous signs exist to show leaks in chimneys. The easiest way to notice is if you see water dripping in the firebox after a storm. If you hear dripping, then you’ve got issues. At the same time, do not be surprised for there to be a musty smell. Another sign could be damaged bricks around the chimney. If you see this, you should have your chimney inspected.
While harm may arise, a homeowner can take proactive measures to prevent damage. First, make sure to do an annual chimney inspection. Second, we recommend sealing your bricks on a regular basis.
