Cleaning gutters can be fun, (or maybe not). It is also full of hazards. If you have been neglecting this chore, don't worry, You will still be rewarded by making gutter cleaning a project before rains begin to fall.
One reason is to make sure the water flows away from the house, or else it may break into the foundation. Water can damage a home's foundation in as little as 3 years depending on the age of the home. Water can also damage personal belongings kept in a basement.
If your gutters are full of debris like leafs, tennis balls, shingles and so on water will not flow. It will work its way into the house, rot the fascia boards, the soffit, the plywood in the roof and even the rafter tips.
To cut down on maintenance of your gutter system you can install a leaf guard product, but keep in mind you will need to inspect these products at least once a year to ensure they are working properly.
