Can the Snow From Pennsylvania Winters Damage My Chimney?

Can the Snow From Pennsylvania Winters Damage My Chimney?

While Pennsylvania may not have the worst winters in the country, its residents are still well-acquainted with snow, ice and freezing temperatures. Any level of winter weather can cause chimney damage.

How Snow Can Damage Your Chimney

The main issue with snow is it turns into water. As many homeowners know, water can be a highly destructive substance. Here's how it affects chimneys:

  • Deteriorates masonry: Many masonry materials, like bricks and mortar, absorb moisture. When moisture from melting snow and ice penetrates the masonry, it exposes the material to freezing and thawing. This process causes the structure to expand and contract, accelerating deterioration.
  • Causes rust on metal components: If snow or ice gets into the chimney, it can cause metal parts, like a cast iron damper, to rust. Rust is never a good thing, especially if it affects damper functioning.
  • Cracks the flue liner: A flue liner protects the masonry inside your chimney from creosote buildup and helps carry combustion gases out of your home. Over time, water from snow or ice can cause the flue liner to crack. Dangerous gases could get trapped in a cracked liner, so it's important to keep this part of your chimney in great shape.

How to Prevent Snow and Ice Buildup in Your Chimney

We might not be able to keep winter storms away from your home, but we can prepare for them. Here's how to prevent chimney damage from Pennsylvania's winter weather:

  • Have it professionally inspected: Before winter arrives, schedule a chimney inspection with a certified technician. A trained technician will thoroughly check your chimney for damage. They will also recommend any repairs you may need and ways to protect your chimney from winter weather.
  • Install a chimney cap: A chimney cap is basically your chimney's roof. It plays an essential role in keeping snow and water out of your chimney. We recommend installing a chimney cap, or repairing your current one if needed, as soon as possible.
  • Repair or install flashing: Flashing consists of sheet metal and is placed around your chimney where it meets the roof. It helps protect the chimney from leaks and moisture. Installing flashing or repairing your current installation will guard against snow and ice.
