Keeping Snow Out of Your Chimney

Ho, Ho, Ho! ‘Tis the season for keeping snow out of your chimney. As winter approaches, many Pennsylvanians look forward to warm and cozy fires by the fireplace. But before you light the first log of the holiday season, ensure your chimney is ready for the fluffy white stuff that often blankets our neighborhoods. Here in Southern Pennsylvania, where snowfall averages nearly two feet annually, keeping snow out of your chimney is essential. 

The Dangers of Snow to Your Chimney

Snow, like water, can cause significant problems:

• Structural damage: The weight of accumulated snow can strain the flue liner and chimney walls, leading to cracks, leaks, and even a structural collapse.
• Chimney leaks: Melting snow creates moisture pockets within the chimney. This moisture can contribute to water leaks and creosote buildup, a highly flammable substance that increases the risk of chimney fires.
• Carbon monoxide exposure: Blockages caused by snow can prevent proper ventilation, trapping harmful carbon monoxide fumes inside your home.

How to Keep Snow out of Your Chimney

Install a Chimney Cap

The chimney cap is the stack’s first line of defense for keeping snow, rain, and debris out of the flue. Choose a metal cap with a fine mesh screen to allow smoke to escape while keeping snow and unwanted guests out.

Consider a Cricket

A cricket, also known as a saddle, is a triangular sloped component installed at the base of your chimney that diverts rain and snow from the flashing. It can be especially helpful in areas with heavy precipitation.

Seal the Flashing

Ensure the flashing, the sheet metal that seals the joint between the chimney and the roof is in good condition. Any gaps or cracks can let water and snow seep into the chimney. You can use a putty knife or caulk gun to apply flashing sealant around the edges of the flashing and over any gaps or thin spots. 

Waterproof Your Chimney 

Cracks in the masonry can allow water (and melted snow) to seep in and damage the bricks and mortar. Regularly inspect the masonry, including the chimney crown, for cracks and have a professional sweep make any necessary repairs. After making repairs, apply a vapor-permeable water repellant to keep snow out of your chimney while allowing any trapped moisture to escape. 

Schedule Regular Chimney Sweeps

A CSIA-Certified Chimney Sweep® is specially trained to remove soot, creosote buildup, and other debris that can ignite and cause a chimney fire. Regular inspections also allow the technician to identify and address any potential problems caused by water intrusion, including those that could worsen with snow accumulation.

By taking these steps, you can keep snow out of your chimney throughout the winter season. Now you can focus on the fun things – decorating the tree, baking gingerbread cookies, and enjoying the warmth and comfort of your fireplace or stove.
