A more slow however more long-lasting arrangement is given by the utilization of copper or Zinc strips set at spans on the roof surface. As downpour runs over the metal strips a fungicidal wash covers the roof region. The bigger the space of uncovered copper, the better the outcomes. The strips should be put at stretches down the roof to guarantee adequate fungicidal wash covers the roof. For a normal estimated house one length along the ridge with a subsequent mostly down the roof is adequate to hold the lichen down. Following a couple of years the copper will acquire a green patina and the fungicidal properties will be decreased. By cleaning this patina away the copper can be “reactivated”.
