Maintaining a clean rain gutter is very important, since these drains are responsible to transfer the accumulated rain water from large surfaces, like a terrace, to an area where water can be drained out.
Gutters are an important part of any home without which a property would face serious damages due to water leakage. In fact it can be safely said that, if there had been no drains, then rain water, which gets accumulated on the roofs would gradually get soaked in by the walls of a house which in turn would damage the entire structure
