We use a method called soft washing, we don’t use any pressure on the shingles as it will damage them and shorten the lifetime of your roof. We first blow off all loose debris, then we apply a liquid chemical solution that kills the moss, algae and lichen instantly. You will know the moss is dead because it will turn white and look like snow. Over the next 4-6 weeks the roots will dry up and it will fall of naturally. This process does not do any damage to your roof and follows the shingle manufacturer recommendations for cleaning asphalt shingles.
