The Importance of Chimney Flashing

Chimney flashing is the aluminum, stainless steel or copper lining that is designed to fit over the seam where the roof becomes the chimney. Because each chimney and roof are different, it is vital that the flashing be customized to fit with your particular chimney and roof. When the chimney flashing is not custom-fitted or properly installed, or when it is damaged, corroded, or bent by winds or animals, it can no longer serve the purpose of providing a watertight seal. Because flashing is typically made of metal, over time it can corrode and rust, creating holes and rendering it ineffective. Without effective flashing, your chimney is left unprotected from water-damage at its most vulnerable point.

How does chimney flashing work?

Chimney flashing consists of multiple, custom-fitted, metal segments placed under the shingles surrounding the chimney and along the wall of the chimney itself. Next, a layer of urethane caulking is used to seal and water-proof the area. Because the chimney flashing is customized to the individual roof and chimney, it is important to have it checked as the house settles and shifts and when having the roof re-shingled. Any shift in the home can create a space or gap in the flashing. This separation, no matter how small, can lead to big problems and extensive damage.
