Ayan Carcamo is a master coppersmith and project supervisor for Slate &  Copper Services.  Pictured here admiring a through to the flue copper chimney flashing  on a new home construction project being built by Pecora Brothers in Greenwich,  CT. This type of chimney flashing method is required by the Greenwich building code for new construction.  Flashing the chimney to the flue prevents water infiltration due to masonry saturation.
