A leader head is a device used in roof drainage to capture stormwater runoff from the rain guttering of a building. Generally speaking, such a device is known as either a leader head, collector box, or a conductor head within the fields of Architecture, Building Design and Construction. Leader heads are commonly made from sheet metal in the form of a box of varying shape and size which is open at the top and has one or more outlets to which downspouts are attached.
Leaderheads can be used to catch a roof scupper or drain, connect two or more downspout lines together, or give a decorative feature to the downspout. There are numerous design options to compliment any style of architecture. Many customers choose to use a leaderhead as a decorative feature on their home. The leaderhead can add architectural design to the downspout creating a much desired look.
