Gutters are designed to direct rainwater away from your home. But if they get backed up and clogged with leaves and other debris, they can't do their job. Actually, they will do just the opposite - they will wreck your home. Water damage and mold on the roof, eaves, and other areas are a common result of poorly maintained gutters. Not only is it unsightly, it causes actual damage that will lower the value of your home. The cost of repairs can be literally "through the roof." Preventing water damage by cleaning your gutters is a strong case of maintenance being much less expensive than repairs.
