How to Install a Chimney Cap?

With Winter fast approaching, you have probably begun to yearn for the fireplace warmth to add that oomph to your house. But before you pile up the wood to light the fire, we need to help you ensure your chimney is in the right shape. One way of doing this is by helping you know how to install a chimney cap.

What is a Chimney Cap?

A chimney cap is a protective covering that protects your chimney from water, pests, snow, and other external substances. Without it, your chimney’s flue and surrounding roofing material are prone to damage.

Chimney caps come in different varieties; they can be stainless steel, copper, or galvanized metal. Your choice will depend on the state of your fireplace and your budget.

The most recommended is stainless steel because of its sturdiness. Though low-priced, galvanized chimney caps cannot work with gas logs and are more likely to rust and damage your chimney in the long run.

Safety Measures

Whether you are installing a chimney cap for the first time or replacing a broken one, you will encounter the dangers that come with heights. In light of this, the following measures are likely to enhance your safety: 

  • Ensure you wear a safety harness to protect yourself from falling.
  • Use an extension ladder with a ladder jack. Avoid A-extension ladders because they often tend to be unstable 
  • It is advisable to work with  a partner who will hand your tools and help hold your ladder to keep it steady.

Tools and Equipment Required     

  • Marking Pen
  • Caulking Gun                                               
  • Construction Adhesive
  • Safety harness
  • Brush
  • Impact driver
  • Extension ladder

Steps Involved

1. Measure the Flue opening

Find the length and width of the flue and record the dimensions. 

2. Purchase a Chimney Cap

Take the measurements with you to your local hardware or share them with an online chimney cap supplier. Your cap should be at least  6 inches taller than your flue to allow it to vent effectively. If you cannot find a cap that perfectly fits your chimney, you may have to order a custom-made one.

3. Attach and Secure the Cap

Climb up your roof with the brand new cap. Install it by placing it over the chimney and pressing it down until it is securely fitted.

If dealing with a metal flue, you can use an impact driver to secure the cap. If your flue is made of clay, it is advisable to anchor your cap using masonry screws.

Despite playing a significant role in chimney operation, the chimney cap remains one of the most neglected parts of a chimney.

This does not have to be so; a simple chimney analysis by a certified chimney sweep will determine if your cap needs repair, maintenance, or replacement altogether.

Many homeowners assume that a fireplace cleanup is the most significant procedure in chimney maintenance. However, a defective chimney cap can do much more damage to your chimney than an untidy fireplace. 

Before you light up your fireplace this festive season, ensure your cap is effective enough to take you through the cold season.
