Moss is essentially small flowerless plant species which grow typically into green clumps. Moss loves and seems to grow well in moist cool areas. Recently getting a new classification of its own called the division Bryophyta with over 12,000 species. The reason why moss loves to sit on moist roofs is because how they do not have flowers or seeds, meaning they do not have a secure water system. This is the reason why your damp roof is a perfect place for them to grow on.

  1. Enviornments with acidic pH levels. Moss grows optimally within a pH level of 5.0 to 5.5
  2. Shade can be partial but shade definitely optimizes the growth.
  3. Moss has to have a moist or humid enviorment to survive.
  4. Hard surfaces like your shingle roof or house siding is where moss grows the best.
  1. Remove any shade caused through out the day to your roof or affected area.
  2. Wherever the Moss is growing, make that surface/environment super acidic or past a neutral pH level of 7 into a base environment.
