How Do Leaks Start in a Chimney?
When you take a look at this picture, you can clearly see that mortar fell out from in between the bricks and additional cracks and loose mortar are next to the empty spot. This is an open invitation for water to continue to break down the mortar and water to make its way into the home. But it is such a small area. Can it really do that much damage? Let’s take a closer look.
Here are the Top 3 Ways Leaks Start in the Chimney
- Water that flows in from the top of the chimney. Meaning there is no chimney cap or the chimney cap is damaged in some way that allows the water to enter into the chimney.
- Damaged or Missing seals of the Roof Flashing. Flashing can be very tricky. If there’s one little spot open, water will find its way in. Once it finds the weak spot, it quickly begins to erode away at it until it makes it way into the home.
- Cracks in the bricks and Mortar. That’s our picture for today. Not only are there cracks but also missing mortar.
Flowing from the Top
You may think it’s unbelievable that a chimney doesn’t have a chimney cap, but you would be surprised how many are out there constantly exposed to the elements of the weather. The chimney cap serves a very important task of keeping water, snow, debris and animals out of the chimney. Some homeowners may think that the hole is too small and the small animals can’t make their way to the top. But they can and do. This is why a chimney cap is an important part of protecting your home.
The chimney cap covers the open hole where gases and smoke from the woodburning fireplace and gas fireplace escapes. It’s protecting it from rain, snow, leaves and animals from coming in. Rain and snow can damage the chimney from top to bottom. The leaves can get set on fire and cause a fire in your home. Animals…well do you want a burning animal in your home? Me neither.
Damage or Missing Seals from the Flashing
This is a tricky one. Flashing is placed where the roof meets the chimney. Because this is a place where water can settle and make its way into the home, flashing acts as a barrier. One of the primary weak spots with flashing is the breakdown of the seals. Once the seals dry up and begin to crack and flake, water can make its way into your home. Inspection each year during your fireplace service is key to keeping the elements where they belong…outside.
Cracks in the Bricks and Mortar
Cracks in the bricks and mortar is a perfect way for leaks to start in the chimney. The small hairline cracks can’t be seen from the ground as they can be small or very thin. This makes it difficult for homeowners to keep on top of repairs, which is why having a certified chimney inspection done can save you from unnecessary repairs on the inside ceiling, walls, wood and more. By ensuring holes or cracks are regularly inspected and repaired, you will have significantly reduced the amount of issues that can plague your home.
