We have done a few cottages this summer on a lake in Northern Michigan, but this was by far the roof with the worst moss infestation.  This side of the roof faces north, and has trees next to it.  Because of the years of neglect there is some granule loss on the shingles. But, we were able to clean it, and help it to last a few more years. If you have a roof that needs cleaning in Michigan, call the soft wash pro's at Kleen. 616-914-9064
