A chimney pan refers to the flashing that is built into the chimney when it is either constructed–or in the case of existing chimneys–it is torn down to the roofline and rebuilt.
Because the chimneys are built of bricks, which are porous and absorb water as they age, a full thru-pan flashing is the best way to ensure leaks will not occur. Traditionally many masons would use a large sheet of soft lead. However, the lead is prone to rips and tear and does not hold up as well as a copper flashing.
Our coppersmiths fabricate and install copper chimney pans on site for many local builders and masons.
