Box Gutters

Box Gutters

Box gutters can be found on many old and historical buildings. They were the gutter of choice years ago before pre-formed metal gutters became widely popular. A box gutter does not hang onto the edge of a roof or on the edge or side of a house as many modern pre-formed metal gutters do. A box gutter is actually built into the bottom of the roof or into the roof overhang. The foundation of most box gutters is wood that is then covered with thin sheet metal such as tin, copper, lead, stainless steel, or some other metal that will not readily corrode. A rubber membrane was used to reline this box gutter when the flat roof was replaced.   Due to the lack of slope in the design, they can clog easily and back up causing water to enter the over hang and wall.  Wood rot is often where this system fails.
