Is Your Chimney Crown Cracked Or Damaged?

Your chimney may seem like a simple brick structure from the outside, but it is actually a complex system that plays a vital role in the safe and efficient operation of your fireplace, stove, and other heating appliances. One of the most critical parts of this system is the chimney crown. 

What is a Chimney Crown?

The chimney crown is the concrete slab or metal plate on the uppermost section atop the masonry structure. 

How does the crown protect the chimney?

Rain, snow, and ice can damage your Rochester chimney. The crown’s sloped design and drip edge divert water from your chimney and home, preventing potential leaks, deterioration, and water damage. 

• The crown helps prevent downdrafts, which can blow smoke back into your home and hinder airflow for your fireplace or appliance.
• It also helps keep out small animals and pests that can sometimes enter chimneys through a cracked or damaged crown. 

Common signs your chimney crown is cracked or damaged

Since your chimney crown is typically the home’s highest point, it often takes the brunt of Mother Nature’s force – gusty winds, lake-effect snow, ice, and heavy downpours. House settling, lightning, and even earthquakes can cause cracks in the crown. However, many homeowners often miss visible signs of damage due to its location. So, here’s what to watch for:

Visible Cracks

Hairline cracks might not seem like a big deal, but they allow water to seep in and worsen over time. Look for cracks in the crown, especially large or horizontal ones, after a significant weather event. 

Crumbling Mortar

The mortar between the crown’s bricks or stones should be intact. If it’s crumbling or missing, water can easily penetrate the structure.

Spalling Bricks

Visible signs of chipped or cracked bricks indicate water damage within the crown. 

Water Stains

Look for dark streaks or stains on the chimney’s exterior and below the crown. It can indicate water leaks.

Signs of Interior Damage

Don’t ignore water stains, rust on your fireplace damper, or a musty odor coming from the chimney; they suggest water is getting inside.
