Clogged gutters are annoying, so as the cleaning of those high channels. If there are larger trees close to the house, it is recommended to cover the rain gutters with a lattice grille. That is not difficult at all but very helpful and practical. Get the clean rain gutters using Laubstopp which offers two special plastic-based Laabop systems.
This system is available in two sizes (half-round channels RG 150 to 180 and RG 100 to 125) and in two meters length that costs per meter.
