Many homes in Connecticut have moss growing on the roof. Normally it is on the north side of the house and caused by shade and organic material preventing the roof from drying out. The moss needs this moisture to survive. They do not have a “root” system like a tree that goes deep down into the soil. Moss has a filament cell structure called RHIZOIDS. These rhizoids serve the function of attaching the moss to the roof, absorbing water and are only one cell thick. Sort of like a straw these rhizoids suck water up for the rest of the plant to live.
The other thing moss to live is the food it creates with chlorophyll. From the photosynthesis the chlorophyll is the agent that creates the food moss needs to live. Wipe out the chlorophyll and you starve the moss, it dies and falls off.
Our process is to mechanically remove as much moss as possible prior to cleaning. This allows the cleaning materials get down to the rhizoids and kill any them. The second way we remove the moss is the cleaner wipes out the chlorophyll so what cannot be easily removed turns white, dies and falls off.
Our soft touch roof cleaning allows me to see what is going on every step of the way, so that monitoring the impact to the roof and shingle is always visible. If too much grit is being remove the process is adjusted and can be all the way down to nothing but a soft mist and no brushing can be done with great results, it just takes a little longer to see the final result of a nice clean roof.
