If your chimney is leaking, identifying the source of the water intrusion can be challenging. Since the chimney is always exposed to the weather, there are numerous ways for water to penetrate.
How Can Water Damage My Chimney?
Water damage to a chimney is a common issue that can lead to serious structural and safety problems if not addressed promptly. Understanding how water can harm your chimney is crucial for taking preventive measures and maintaining the integrity of your home.
- Freeze-Thaw Cycle: Water can seep into small cracks in the masonry. When temperatures drop, the water freezes and expands, causing the cracks to widen and leading to structural damage over time.
- Deterioration of Mortar: Continuous exposure to moisture weakens the mortar that holds your chimney together. Over time, this can cause the bricks to loosen or fall out, compromising the chimney's stability.
- Rusting of Metal Components: Water can cause rust on metal components such as the damper, firebox, and chimney cap, leading to their deterioration and potential failure.
- Mold and Mildew Growth: Persistent moisture can lead to the growth of mold and mildew inside the chimney, posing health risks and further degrading the masonry.
What Is Flashing?
By layering and strategically overlapping these strips, flashing creates a waterproof seal that protects your chimney, roof, and interior from water entry or damage. When properly installed and maintained, flashing can preserve a watertight seal for the lifespan of your chimney system.
However, several factors can cause flashing to fail. Here are some common reasons for flashing leaks:
- Changes to the roof, such as replacing shingles;
- Attempted animal entry;
- Long-term exposure to the elements;
- Incorrect installation, including excessive nail holes;
- Natural shifting or settling of the house.
