When the chimney has no protection with the aid of a solid chimney cap, pests and vermin like raccoons, birds, and squirrels make their properties in the chimney. Animals like critters have a special attraction to chimneys and come along with lice and maggots, spreading diseases and foul odor. Further, reptiles like snakes usually climb in the course of the chimney and make way into the house, posing a threat to the lives of the occupants.

A few birds just like the chimney swift are attracted to the warmth presented by means of the chimney, causing them to build their nests and block the flue in severe winters. The issue worsens while these birds and animals get trapped in the flue or die due to the smoke rising out of the fireplace. The carcass of these animals no longer in simple terms decomposes and emits a foul odor, but also prevents the smoke from leaving the chimney. Causing soot damage and extreme carbon monoxide poisoning within the house.

An adequately-sized and professionally-installed chimney cap can preclude all of the aforementioned uninvited guests from entering your chimney. Invest in a good-quality top-mounted cap with a pleasant mesh (ideally ¾th of an inch), allowing adequate airflow, but preventing animals from entering the chimney.

Offers Coverage from Chimney Fires and Downdrafts

Unruly embers and sparks from the fireplace can easily travel up the flue and land at the roof. Increasing the risk of fire and roof damage. Therefore, it’s advisable to install a chimney cap with a heavy-duty mesh or spark guard that can arrest the embers capturing out of the flue. Preventing them from damaging the roof or other estate within the vicinity.

Further, it’s a false notion that the chimney cap interferes with the circulate of draft moving out of the flue. On the contrary, a chimney cap can enhance the draft in the course of the chimney. The problem of downdraft is commonly faced through households located in windy and rainy areas, such as Chicagoland or Seattle. In those areas, the most widespread challenge is the strong winds that cause the draft and smoke to sneak back into the home. Downdrafts now not simply reduce the fireplace performance but also allow poisonous flue gases to enter the home. Posing a large threat to the occupants.

Placing a chimney cap will restrict wind-induced downdrafts, decreasing the chance of poisonous gases getting into your home. In areas with severe winds, a standard cap may no longer be adequate to restrict the difficulty of downdrafts. You may want a special draft-increasing chimney cap improves the draft at the chimney. And directing the smoke up throughout the flue. Your chimney provider professional may also advise installing a flue stretcher that increases the length of the flue. Enabling you to cut down the amount of downdraft caused through the strong winds.

However, it’s important to recognise that chimney caps can blow off in areas subject to stormy weather conditions. Hence, in case you stay in a town like Seattle receiving rains and winds throughout the year, it is clever to ask a reputed Seattle chimney sweep service for recommendations on cap weights to your area. Only a professional can guide you with the additional steps required to ensure that the chimney cap stays secure in the course of powerful winds.

When installing a chimney cap, make sure it’s extra than five inches above the flue top. This would allow the smoke to easily discover its way out and stopping downdrafts.

Prevents Organic Particles Build-Up


In the absence of a chimney cap, organic and flammable particles like twigs, sticks, dry leaves, and hay may land up and accumulate within the chimney. Blocking the flue and increasing the danger of fire. Further, whilst your fireplace isn’t in use in off-seasons, the trapped organic material decomposes, emitting a bad chimney odor.

Installing a high-quality chimney cap with a mesh will preclude these odor-causing materials from entering the chimney. Reducing the chances of spending a pungent summer time or spring on your abode.

Reduces Moisture Damage

Moisture can cause considerable damage to the chimney structure. That is especially real in regions receiving heavy snow and rain. Places where the masonry and mortar joints expand and contract as the water thaws or freezes. This intermittent freezing and thawing can cause cracks in the chimney structure, attracting costly repairs. The moisture can also leak inside the house attic and damage your ceiling and walls. Further, moisture damages the chimney liners, crown, and dampers, reduces the efficiency of your fireplace and increases the chance of fireplace mould and mildew.

Install a cap with a flat top surface to easily extend around the perimeter of the chimney. This would block the rain, snow, and ice from entering the chimney, thereby decreasing your stress. Stainless steel and copper chimney caps are durable, moisture-resistant, and offer an attractive shrink appeal to the home. They often come with a lifetime warranty.

On the other hand, caps made of galvanized metal are a cheaper and a less-durable option. Hence, they come with a constrained warranty. Make certain you put money into top-quality chimney caps that offer a warranty for enduring the heat. As good as smoke, heavy rain, and snowstorms.

Lastly, in case your location reports heavy rainfall, a regular cap may be incapable of retaining the water out of the chimney. Ask your local chimney care professional about installing a multi-flue cap which can correctly tackle this situation.


Most property owners who have a fireplace in their home don’t see the desire to install a chimney cap. However, a good-quality chimney cap acts as a protecting roof for the chimney. Preventing animals, organic debris, and moisture from coming into into your house. Further, chimney caps also restrict downdrafts, protecting you and your family from toxic gases and fire mishaps.

If your chimney isn’t capped yet, we are certain the information shared during this post will encourage you to make this small and clever investment. Thereby retaining your house safe and in good condition.
