A chimney cap is a protective covering that goes over the top of your chimney enclosure to keep it dry. They’re usually made of stainless steel, copper, or galvanised metals, and feature a mesh screen to keep airborne hearth sparks, nesting outdoor animals, and damaging precipitation and debris from interfering with the overall protection and longevity of your fireplace’s necessary venting system.

Why is it so important to keep sparks contained inside your chimney while keeping these other elements out? When you’re toasting marshmallows and having intimate conversations by the light of your fireplace’s hearth, a lot is going on in your chimney’s venting room. The sparks created by burning wood or fake logs will reach the top of your chimney and, if not properly stopped, ignite the flammable materials surrounding your chimney wall, such as your roof and house construction. And all it takes is one stray spark in the breeze. Nesting animals like squirrels and birds can find a safe haven in the top of your chimney without anyone noticing… until it’s too late.
A chimney cap keeps them out, as well as their harmful waste, out of the building, avoiding foul odours and the mites that waste brings. Year after year, the chimney top is exposed to rain, snow, hail, and strong wind gusts. Rain will soak into the mortar joints of your chimney’s construction, loosening the bricks or stone of your masonry chimney if you don’t have a chimney cap to protect it from the elements. Alternatively, if your chimney is made of metal, moisture will cause it to rust, causing it to deteriorate quickly. Leaves and other debris are blown through your chimney by strong wind gusts.
These flammable materials will quickly suffocate your flue, preventing it from venting the required fire by-products, resulting in dangerous chimney fires and the downdrafting of trapped smoke into your home. Investing in a chimney cap is a cost-effective and simple way to keep a Pandora’s Box of natural calamities out of your family’s safe haven, such as burning, illness, expensive repairs, and strife.
Chimneys come in a variety of shapes and sizes.
The first step in getting a chimney cap is figuring out what kind of chimney you have. This will decide which chimney cap will work best for you. A masonry chimney, which is made of brick, stone, or concrete, is the most common form of chimney. Metal Chimneys, also known as factory-built chimneys, are mass-produced, usually come with a pre-fit chimney cap, and must be used with one because metal is less resistant to Mother Nature’s elements. For masonry chimneys, chimney caps are typically available in three basic sizes: 8″ x 8″, 8″ x 12″, and 12″ x 12″, but custom designs and fits are also available.
Flues Come in a Variety of Shapes and Sizes
It’s important to know what kind of flue your masonry or factory-made metal chimney uses, regardless of whether it’s masonry or factory-made metal. Simply looking down into the depths of your chimney will reveal this.
