Cedar roofs and shingles are generally porous in that it is easy for algae, moss and lichen to plant there root like connectors. Once they do this it can be very difficult to remove them without causing damage! The best solution is to maintain your siding properly from day one, which would mean have the wood cleaned and conditioned every 2-3 years so that the wood always stays in tip top condition. This can be impossible for some and others may even buy a home and inherit a building envelope that has not been properly cared for. If this is the case the wood may be very tender due to the various growths causing over saturation of the wood. Since most cedar in Massachusetts is not brand new any more it needs to be maintained professionally by a company that knows how to get the job done without causing any damage. It's best to hire a Cedar roof cleaning company that uses a Softwash (non pressure) method.
