摘要

The invention makes it possible, by virtue of a copper section or strip 2 fixed directly to the ridge tile by means of a clip or of a glue which has to have good properties of adhesion and elasticity, to prevent the formation of moss and of lichen over the whole of the roof. The copper strip 2 fixed in this way oxidises under the action of moist air containing carbon dioxide and becomes covered with hydrocarbonate called "verdigris", the salts of which are released and spread themselves over the whole of the roof carried by rainwater thus preventing the formation of moss.
