Proper roof cleaning and maintenance of your roof will improve longevity and prevent serious damage to your property. The roof should be clear of any debris (branches, leaves, pine needles). Debris can trap water, not allowing proper run-off. It can also cause rot and discolor to the roof.
Gutters should also be regularly cleaned. Debris will rot inside the gutter, creating dams and plugged downspouts. Proper water run-off is crucial to the life of the roof.
