Why Would My Chimney Be Leaking?

Chimney leaks can be detrimental to the overall condition of your chimney structure. Water damage can lead to failing brick and mortar, mold and mildew growth, and chimney discoloration. Prevention is key and we’re here to help you understand common causes, solutions, and methods for stopping a leaky chimney in the future.

Missing or Damaged Chimney Cap or Crown

Your chimney cap is meant to protect the chimney’s interior from things like water, debris, and animals. If the cap is rusted, damaged, or missing it can allow water to run straight into the chimneys opening and wreak havoc on your masonry.

Your chimney crown is the cement slab located at the top of the chimney structure and its main job is to direct water away from the masonry. If your crown has cracks it can allow the water to pool and seep into the chimney’s masonry, accelerating the rate of damage over time.

Damaged Chimney Flashing

Chimney flashing is a sheet of durable metal that is installed at an angle at the base of your chimney. Flashing is meant to seal the space where your chimney meets your roof and direct water away from that location. If the flashing is damaged it can allow water to build around your chimney base and create a leak in your roof.

Compromised Masonry

As your bricks and mortar soak in the water they become saturated and expand leading to something called spalling. If this problem is not addressed, your masonry will crumble and fail leading to potentially serious damage to the entire structure.

Repair or Replace Damaged Chimney Parts

If any part of your chimney is damaged or missing, you will likely need to schedule a repair or replacement in order to save your chimney. Replacing the damaged part will help stop the leak and protect your chimney from further moisture damage.

Masonry Repairs

If your masonry has taken on severe damage a partial or complete rebuild may be necessary. However, for many cases of damaged mortar, a chimney technician will be able to resolve the leak with a process called tuckpointing. Tuckpointing consists of replacing damaged or failing mortar with new mortar in order to preserve the condition of your chimney structure.
