Roofing materials like tiles, slates, fibre, cement and asbestos all become dull and weakened by moss growth. Even the thinnest layer of moss is a problem because it acts like a sponge, absorbing water, which increases the weight and stress on the roof, shortening its productive life. Frost damage is another problem - by pushing the tiles up and cracking them. Areas serviced: Dundee Perth Localwww.copperridge.co.ukQuayside House/Friarton Rd, PH2 8BB
