Found quickly: The right gutter for your roof:


Roof gutters and down pipes are given in recommended sizes (RG/DN) as specified in DIN 18460. The correct size for your roof depends on the surface area of your roof and the number of drainage Points. Example for calculating the recommended sizes in accordance with DIN 18460: The gable roof of a house that is 15 metres long and 10 metres wide requires drainage. Therefore, the layout of the house amounts to 150 m2. If a down pipe is fitted to each side of the house, the layout that requires drainage is then 75 m2. According to the table, this indicates that a Marley RG 125 roof gutter and a Marley DN 105 down pipe should be used on each side. If two drainage points are fitted on each side of the house, the layout area requiring Drainage is halved to 37.5 m2. The table now shows that one Marley RG 100 roof gutter and two Marley DN 75 down pipes should be installed on each side.

The roof surface that must be connected / layout surface in m2 Recommended size for roof gutters, semi-circular, box and duplex gutters Recommended pipe size (DN) in mm
up to 25 m2 RG 70/10 parts DN 53
up to 25 m2 RG 75/10 parts DN 53

up to 100 m2 RG 125/ 7 parts DN 105
up to 159 m2 RG 150/ 6 parts DN 105
