When and Why You Should Replace Your Chimney Caps?

Reducing the amount of water that penetrates the chimney is one of the best ways to keep your chimney in good condition. A chimney cap is an essential part of a chimney that makes your chimney dry. It has other functions also, such as it protects the masonry chimney crown & open flue. There are mainly two types of chimney caps. Generally, older homes have an open-style chimney cap which was made from leftover cement & mortar from the original chimney construction.

there are various reasons to replace your chimney cap with a new one

why do chimney caps matter?

One of the most significant functions of a chimney cap is to retain water from coming down the chimney. Water can damage stainless steel liners & it also allows mold & mildew to grow. Water will penetrate the masonry & cause damage as the moisture freezes & thaws during the year. A chimney cap is to keep animals & birds that find your chimney a beautiful place for their nest. In addition, the chimney cap will keep debris like leaves & branches out of the chimney. Chimney caps can also support raising your home’s safety by blocking embers & sparks that could otherwise exit the chimney & start a fire on the roof. The chimney cap continues its exposure to strong winds & heavy rain could cause it to loosen or blow off the chimney. It does not matter whether it is tightly secured. The wrong size cap or incorrect installation also affects the chimney.

Missing Cap

Many homeowners do not realize when the chimney cap has blown off during a storm. It is one reason it is significant to have regular chimney inspections. Because sometimes, you notice that a chimney cap is missing due to a storm, then you should not take a chance; you should directly contact experts for chimney cap installation.

Warped Cap

You should check the cap of the chimney on a regular basis, or you can do it by the technician to check the actual condition of the chimney cap to watch for warping. It is susceptible to further damage & will be less effective at keeping debris & animals out of the chimney if the top of the chimney cap has started to pull away from the sides. It also raises the likelihood that the entire cap will be blown away by strong storms.

when should chimney caps be changed?

Rusted Screens

Any rust or dust on the chimney cap is an additional reason to change the cap. A heavily rusted cap or screen shows that the integrity of the entire cap or screen has been compromised. Further damage is unavoidable, & the cap should be changed. A rusted cap can induce more damage if it is not handled properly.

Damaged Screens

Damaged screens also need replacement. Any holes in the screens that cause separation between the screen & cap will let birds or rodents make their way into the chimney. You should change the cap rather than risk a pest problem because these pests can fit through very small holes.

Creosote Buildup

Creosote build-up on the screens is very dangerous because it is highly combustible. In some cases, the creosote can be cleaned off easily, but in some cases, it creates a thick enough layer, which cannot be handled easily. At that time, it is best to change the cap rather than risk the creosote igniting & causing a fire in the chimney or on the roof.

Clogged Turbines

It is very important to make sure the turbines are working properly if you have a draft-enhancing chimney cap. You should have the cap changed if they are no longer burning because they are clogged or otherwise damaged.

Leaking Water

There is a good chance that the cause is a damaged chimney cap if water is coming in the chimney around the flue, even if you cannot see the actual damage. If you notice leaking water, then you should call the chimney repair service provider immediately to save yourself from further damage.

Water and debris in the firebox

Water is the worst enemy of the chimney. It can soften the masonry, which can lead to extensive damage & repairs. Smoke & fumes may also be invading your living space if water & debris are getting into your fireplace. When this happens, the chimney cap should be inspected and changed if damaged. Otherwise, you will need a more thorough inspection to find the source of the water intrusion.

You’re Experiencing Downdrafts

On windy days, a sudden gust of wind can damage the chimney cap. It can be very messy when soot, creosote, & ash are blown into your living space. A damaged or missing chimney cap is generally the worst situation creator by generating more damage to the chimney. Changing the chimney cap will minimize downdrafts easily.
The chimney cap protects the upper part of your chimney and prevents debris, rainwater, and animals from entering. A certified professional ‘s inspection is required on a regular basis, and as per their instruction, the chimney cap should be repaired or replaced if required. Certified chimney professionals can inspect your chimney with their advanced tools and advise you on whether or not your cap requires any replacement.
