Chimney flashing is made up of a metal barrier that wraps around where your chimney stack comes through your roof. This flashing is made up thin metal usually aluminum, copper, lead or stainless steel. What it does is as the rain falls, it is directed over the flashing away from the gap between the chimney and the roof. This helps prevent any water from running down the sides of your chimney and letting water leak into your home. Here at The Fireplace Doctor, we have several different types of flashing for your chimney. You can view and order them from our online store.
