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.

Things You'll Need

  • Garden hose
  • Roof moss remover

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.

Tips & Warnings

  • Attach stabilizer bars to the ladder to avoid slipping and to protect your gutter from denting.
  • when using a pressure always aim the water spray down the roof, the way rain would fall, never up the roof or "head on" this may damage or loosen shingles.
  • To prevent the moss from returning apply the hydrogen peroxide mix twice yearly and do not rinse off.
  • Household bleach or TSP is not an acceptable substitute for hydrogen peroxide, bleach/TSP can extremely dry out the roofing material making it susceptible to wind damage, it may also alter the color, not only of the roof shingle but any painted surface that it may come in contact with. The run off of these products are hazardous to pets and will damage the landscaping.
