Cleaning your roof can extend the duration of your roof's ability to function. It depends on the type of roof you have whether your roof will last 20 years or 100 years. However, the lifetime of a roof can be cut short simply by the buildup of moisture-rich organisms such as algae, mold, moss, and lichen that can penetrate the roofing shingles and gradually erode the sheathing beneath them. To extend the life of your roof, it is a good idea to keep your roof cleaned which eliminates the streaking and discoloration of your roof which typically happens on your northern slope.
