What is a roof cricket?

A roof cricket is a small ridge-like structure typically made of metal or wood that is installed on the high side of a chimney or other roof projection to help divert water away from it. Roof crickets are commonly used in areas with heavy rainfall or snowfall to prevent water from pooling and causing damage to the roof and surrounding areas.

Roof crickets are also known as saddle crickets, because of their saddle-like shape, and are typically installed at a 30-degree angle to ensure proper water runoff. They can be made of various materials, including galvanized metal, copper, or wood, and are usually covered with the same roofing material as the rest of the roof to provide a seamless appearance.

In addition to diverting water away from chimneys and other roof projections, roof crickets can also help improve the overall ventilation and drainage of the roof, reducing the risk of leaks and other water-related issues. Proper installation and maintenance of roof crickets are essential to ensure their effectiveness in protecting the roof and preventing water damage.
