You are not alone if you have ever looked at a chimney and wondered how it keeps the rain out. Chimneys are an essential component of any home that has a fireplace, but they are often overlooked when it comes to maintenance and protection from the elements. Let’s have a look at how chimneys work to keep the rain out and how you can protect your chimney from water damage.
Chimney’s Work During Rains
Before we dive into how chimneys keep the rain out, you should have an idea about how it works in general. The primary function of a chimney is to let smoke and other combustion extras escape safely from the fireplace. This is possible to do so through a combination of draft and insulation.
When your fire is burning in the fireplace, hot gases rise, making a draft that draws air in from the bottom of the chimney. This said draft carries the smoke and other gases up and out of your chimney, preventing them from entering your living space.
The chimneys are typically lined with a layer of insulation to help facilitate this process. It is done to keep the gases hot and moving upward.
However, things get a bit more complicated when it rains. Rainwater can easily enter the chimney and damage the chimney interior, the flue area, and even the walls and ceilings of your home.
How Do Chimneys Keep Rain Out?
Here is how it works:
They are present on the top of the chimney preventing rainwater from entering. Caps are usually made of metal and come with a mesh screen that allows smoke and gases to escape, meanwhile keeping rain and debris out.
It is a slice-thin piece of metal fixed around the base of your chimney where it meets the roof. Flashing is made to prevent rainwater from seeping into the gaps between the chimney and the roof.
The masonry also helps in keeping rainwater out. Chimneys have an angled top, known as a crown, directing rainwater away from the chimney’s opening.
How To Protect Chimney From Rainwater?
Ways you can protect your chimney from rainwater damage:
Keep Your Chimney Clean
Get regular cleaning done to ensure that it is free of debris and in good working order. A clean chimney functions better and is less likely to suffer from water damage.
Get a Chimney Cap
If your chimney doesn’t have a cap, install one asap. It is quite an affordable and effective way to keep rainwater out.
Check Your Flashing
Ensure the flashing functionality around your chimney; it should be in good condition and not damaged or missing.
Address Water Damage Promptly
Still, even after all the precautionary measures, if you notice any signs of water damage around your chimney, address the issue promptly. Ignoring can cause more serious problems down the road.
