Roof moss remover
Moss growth on a roof will cause deterioration of the shingles or other roof covering. In a worst case scenario, moss will literally eat 50 percent of the life out of costly roof shingles or other roof strata. This problem can be remedied without having to crawl up on a ladder, and not having to scrub the roof surface. Virtually anyone with do it yourself experience can remove moss from a roof, as long as they have access to a garden hose.
Get a pre-mixed bottle of roof moss remover, which is available at hardware stores or home improvement stores. There are many kinds, including environmentally friendly types that will not harm grass or other plants due to run-off from your roof. The bottle will come with a built-in hose attachment port.
Screw the hose attachment port onto your garden hose. Turn on the water.
Spray the roof moss remover onto your roof that is covered with moss. Thoroughly saturate all of the mossy covered areas. Once sprayed, the formula in the roof moss remover will kill the moss, and the next time it rains, the moss will literally wash off of your roof.
