Why Do You Need a Chimney Cap?

Property owners typically ask themselves whether a chimney cap is something they truly require. The fact is, this small and fairly economical setup offers considerable protection against a number of things that might cost you thousands in damage and repair work expenditures. A chimney cap isn’t needed for practical functions, however, it is a terrific way to secure your house from cinders, moisture, and small animals.

Each and every time you utilize your fireplace, there are sparks, the majority of which remain within the fire chamber or somewhere around the chimney’s base. Nevertheless, a few of them are able to (and typically do) get out of your chimney. Setting up a cap guarantees that you are able to light that comfortable fire, without sparks flying out the top of your chimney to start a fire. This might seem like a reach, however, the sparks from your fire can cause such issues.

Chimney Caps and Moisture

Beyond preventing you from lighting the fire, moisture damages your chimney. Ice, rain, and snow all lead to wear and tear and other structural issues in a chimney, specifically when that moisture blends with soot. Even by themselves ice and snow lead to a lot of damage, as the process of freezing and melting is extremely hard on the crown, liner, and walls of a chimney’s masonry.

Things to Avoid When Setting Up a Chimney Cap

The entire point of a chimney cap is to keep debris, moisture, and critters from entering your chimney or house. If you do choose to set up the cap yourself, there are some typical problems you must know about to aid you to avoid them.

An inaccurate chimney cap leads to safety issues, triggering sometimes chimney fires, increased draft, and allowing the elements. Gas log fireplaces shouldn’t be integrated with galvanized chimney caps, as putting the two together triggers corrosive exhaust and rust damage. Copper and stainless-steel caps are more costly, however, they come with fewer issues than galvanized ones. They likewise need less upkeep.
