Chimney collar

A chimney collar is a flashing component that is used to seal the gap between a chimney and the roof. The collar is typically made from a flexible material, such as rubber or EPDM, and is designed to fit tightly around the chimney and extend up the roof slope to create a watertight seal.

Chimney collars are an important component of a roofing system, as they help to prevent water from seeping into the gap between the chimney and the roof, which can cause damage to the underlying structure and lead to leaks and other issues.

Proper installation of a chimney collar is essential for ensuring its effectiveness and longevity. The collar must be installed tightly around the chimney and fastened securely to the roof. It should also be treated with a high-quality sealant to ensure a watertight seal.

In addition to providing protection against water infiltration, chimney collars can also help to improve the overall appearance of a roof by creating a neat and uniform transition between the chimney and the roof. They are available in a variety of sizes and styles to accommodate different types of chimneys and roofing materials, and can be customized to match the color and texture of the surrounding roof.
