Fitting and Usage
BS EN 12056-3:2000 states that gutters should be nominally level (with a gradient of between 1mm/m and 3mm/m where practicable). This standard also states that "where snow is likely to lie on roofs, the front edge of the gutter should not be higher than the projected line of the roof, unless snow guards or other precautions are used".
It is most important to consider the position and number of outlets as well as the size of gutter.
