Can a Cracked Chimney Cap Allow Water Damage Inside?

You might not think much about your chimney cap. It’s just sitting up there, right? Well, that little metal or concrete cover plays a big role. Its main job is to keep rain, snow, and critters out of your chimney. But when it cracks, it loses its protective power. This opens the door for water to sneak in.

How Water Enters Through a Damaged Chimney Cap

Imagine a tiny crack. It might seem insignificant. However, rain is persistent. Water finds its way through these openings. It then drips down the inside of your chimney flue. From there, it can spread. It doesn’t just stay in the chimney itself. It can find paths into your home.

Foundation Concerns
