Project Description

Copper strips will prevent moss, algae and lichen growth on your roof. Thanks to the Sulphur in the atmosphere, when it rains, the H2O bonds with it ans creates very light sulphuric acid, which then reacts with copper and creates Copper Sulphate, CuSO4, and that is what keeps the moss from growing on your roof. It takes about two years for copper strips to establish themselves. This time is a variable that depends on the amount of sulphur in the atmosphere over you and the amount of rain in your area.
