Clogged gutters are one of the biggest risks to your home. Gutters clogged with leaves and debris keep water from flowing properly. Gutter clogs can cause roof damage, allowing water and ice to wear out roof decking and shingles prematurely. Water will also overflow your gutters, pouring down around your foundation. This can lead to costly foundation and basement water damage. With an average cost of just $ 175, you can prevent damage and keep your gutters flowing smoothly.
