What Causes Those Nasty Roof Stains?
Over the years, the make up in the shingle composition has changed.
Most roof stains are caused by the growth of algae, lichen or moss that feed on organic matter found on the surface of the roof. Parts of your roof that get the least amount of sunlight are most likely to have roof stains. This is the reason why some homes may have roof stains only on one side of the roof.
