Every home needs rain gutters. They are an important part of the construction of any house. No one loves them for their aesthetic value, but they protect the beauty of the structure nonetheless, preventing water from streaking and damaging the outside walls and landscaping.They can also become clogged, and the gutters will fill up with water instead of shedding it. This can damage the gutter from the weight of the water. Mosquitoes also tend to breed in standing water left in a blocked gutter.
