Gutters are often neglected because you have to get on a ladder to really see what's growing in them. Organic material builds up over time, creating the perfect conditions for plant growth. Gutters need to be cleaned twice a year to ensure that rain water is diverted away from your house. Ignoring those gutters can result in more costly damage that includes rotted fascia boards, water damage to the sides of your home, and foundation problems. In addition, small trees and shrubs should be trimmed so they are not touching or arching over your house. This will allow for less clean-up, and in damper climates, can cut down on moss on the roof, too.
