What Is Chimney Flashing and Why Is It Important?
Flashing is the thin material, often made of aluminum, steel, or copper, that creates a watertight seal between your chimney and roof. Its primary purpose is to divert water and prevent leaks in one of the most vulnerable areas of your home’s exterior. Without adequate chimney flashing sealing, water can seep into your home, leading to costly damage such as wood rot, mold growth, and unsightly stains.
In Lakeville’s climate, which sees an average of over 30 inches of rain and nearly 50 inches of snow each year, the integrity of your chimney flashing is always at risk. Moisture coupled with seasonal temperature fluctuations can lead to cracking, warping, or degrading of the flashing material.
