What kind of shape is your chimney in after all of the stress of winter? Of course, you know that your chimney was bearing a lot of abuse from the inside, as you put your fireplace or heating stove to good use. But the real abuse a chimney faces during the winter months happens to its exterior. Come spring, the harsh conditions your chimney endured can become evident in the form of chimney leaks.

So how does winter’s freezing weather affect your chimney’s exterior? Masonry materials, like the bricks, stone, and mortar used to build chimneys, are highly porous. Those materials absorb water. The water by itself isn’t a danger, but when temperatures drop, the water freezes and expands. That frozen, expanding water damages your chimney’s masonry. The damage caused by water trapped in your chimney’s masonry and freezing temperatures can lead to leaks.

 

Common causes of chimney leaks

Some common chimney damage that can lead to chimney leaks includes:

  • Cracks in the chimney crown. Your chimney crown is your chimney’s seal against water damage. At the top of your chimney, it protects the inner layers of your chimney by preventing water from pouring down in. When water trapped in the chimney crown freezes, it can cause the masonry to crack. Those cracks can allow water to leak into your chimney.
  • Deteriorated chimney masonry. Just like freezing water in the chimney crown can cause damage, freezing water trapped in your chimney’s masonry can cause damage. The chimney’s bricks and stones can crack or crumble, or pieces of the stones or bricks can pop off entirely. In addition to being unsightly, this damage can let water leak in through the sides of your chimney.
  • Crumbling mortar. The mortar joints that hold your chimney’s bricks or stones together can begin to soften and crumble away due to freeze-thaw damage. Water can seep in through these damaged mortar joints, causing chimney leaks.
  • Leaky flashing. It’s not just masonry materials that can be damaged during the winter months, opening your chimney up to the possibility of leaks. The flashing that seals the juncture between your chimney and your roofline can crack at the seams or develop holes. That can allow water to pour freely into your home around your chimney.
