Lily I have moss growing on the shingles of my roof on the north side of my house what should I do about it?
Thank you for your question, moss growing on a roof cover is an indication of excess moisture exposure, which may lead
to moisture related problems to the roof covering and roof structure. Often proximity to trees, poor roof surface drainage, buildup of organic
debris, and absence of sunlight (usually North sides) and adequate surface drying are possible causes. Treatment to remove moss is often
accomplished using materials containing zinc; however establishing cause for moss formation should be undertaken first as
preventive action. A roofing specialist may be required to assess for cause, damage and repairs.
