What is a common problem with masonry chimney caps?

Masonry chimney caps are crucial for protecting a chimney from water intrusion, debris, and animals. A common issue with these caps is that they are often made from unsuitable materials, which can lead to problems over time. For instance, some materials may not withstand the corrosive effects of moisture or extreme weather conditions, leading to deterioration, cracking, or breaking.

Using improper materials can hinder the cap's effectiveness in directing water away from the chimney structure, potentially resulting in leaks or damage to the chimney and the home. This highlights the importance of selecting the right materials, such as high-quality stone or concrete, specifically designed to endure the elements and provide long-lasting protection.
