Do you have your gutters scheduled for cleaning?
Consider for a moment, the amount of impervious surface area your roof has, that is a whole lot of water run off. It is important that you maintain a free flowing system. To keep walkways ice-free in the wintertime and to keep mosquito larva from developing in the springtime.
Directing water flow away from your house properly will protect your foundation, prevent water penetration, and keep stains from developing on your siding.
