The chimney is one of the essential parts of the house, yet it’s often the most neglected. One way to lengthen the life of your chimney is to ensure the top is equipped with the proper protection. Depending on what type of chimney you have, the top of the chimney could have a chase cover or chimney crown. But, what’s the difference between the two?

We’re here today to go over it all. But first…

Why Do You Need To Protect the Top of Your Chimney?

So, why the top of your chimney need this protection? Aren’t chimneys pretty durable on their own? This is true… however, natural wear and tear, as well as severe weather conditions, can cause damage to the structure. Because of this, it’s essential to take certain measures to prevent any deterioration.

If the chase cover or chimney crown is missing, damaged, or deteriorated your chimney interior is susceptible to water infiltration, water damage, and debris accumulation. Birds and animals might also build their nests in unprotected chimneys, and the sticks, leaves, and other materials they bring in can block the flue which could potentially cause a house fire.

Crowns and covers also work to protect the sides of your chimney from water damage. In the end, ensuring you’re equipped with the parts your system needs will significantly reduce the possibility of dealing with bigger problems down the road, saving you an immense headache, as well as costly repairs, later on.

What Is a Chimney Crown?

Chimney Crowns Chase Covers - Worcester MA - Firesafe crownsThe crown of the chimney is the topmost part of your masonry system. It should be made of a Portland cement-based mixture, but is sometimes made from mortar. In these cases, the crown may need to be rebuilt, as mortar won’t stand the test of time and decay and deterioration is likely to occur.

The crown should be sloped to direct water away from the side of the chimney, protecting it from its number one enemy – water. 

A chimney crown can last many years when properly installed and maintained. However, it needs to be checked regularly for cracks and other damage. Since it sits at the top of the chimney, it’s constantly bombarded by strong winds, hailstorms, heavy rains and freeze- thaw. Having the chimney crown sealed properly is an additional step in preventing deterioration of the chimney.

What Is a Chimney Chase Cover?

Chimney chase covers are installed on the chase of a factory-built chimney, and essentially serve as the “crown” of these prefab units. This typically wooden structure is built around the chimney flue that supports it and prevents water and debris from entering your home.

Chase covers are usually made of metal, such as a stainless steel or a galvanized steel. Some vendors also sell chimney chase covers in different colors to match the exterior of your home.

Chimney chase covers should be of one solid piece of metal and built in a way to allow water to flow away from the top and sides of the chimney. Many homeowners choose stainless steel chase covers over galvanized steel due to the fact that they will not rust and offer durable protection for many years to come.

One More Thing…

Chimney caps are usually made of stainless steel or copper and have a mesh screen to keep out birds, animals, and debris. They also can be powder coated in colors to match your home.

It is important to have a properly sized chimney cap installed in order to have the full benefits a chimney cap has to offer like keeping out water, stopping animals from entering, and blocking out debris.

Which One’s Right for You?

If you notice your chimney is missing a chimney cap, has cracks in the crown, or notice water leaks in your fireplace, consult with a chimney professional and schedule your annual chimney inspection to get the best recommendations on which type of chimney protection is perfect for your home.

When replacing or repairing your chimney crown, chimney cap, or chimney chase cover we highly advise that you leave it to the professionals. Improper installations can lead to further deterioration or damage in the future.
