Trough gutters—also called built-in gutters or sunk gutters—are most commonly found on historic, commercial or public buildings. These types of gutters are built-in to the roof system and do not have hanging gutter components that are visible. When used in combination with pole gutters, a trough gutter system provides a “hidden” gutter system for your historic building, commercial building or classic home.
Whether your trough gutters are performing to the best of their ability depends largely on the integrity of the metal lining and ﬂashings. When it comes to trough gutters, the bigger the trough the more water it can handle. The typical residence will usually require a 5” trough gutter. For homes with a larger roof area, shingle overhang or excessive run-off, a 6” trough gutter is ideal.
