The invention relates to a roof covering for cleaning and keeping the roofs of buildings clean, in particular of plant growth, or pollutants, comprising a sheet-like material (1) which reacts in co-operation with moisture. The sheet- like material forms a partly closed chamber, when in the state of being set upon an inferior roof element (5) and slowly releases the moisture accumulated in said chamber to the exterior.
L'invention concerne une couverture de toit qui sert à nettoyer et à garder propres des toits de bâtiments, notamment en ce qui concerne la croissance végétale ou l'encrassement dû à l'environnement, et qui est constituée d'un matériau (1) en plaques réagissant à l'humidité. Ce matériau en plaques forme, lorsqu'il est posé sur un élément de toit sous-jacent (5), au moins un espace partiellement fermé qui libère lentement vers l'extérieur l'humidité accumulée dans cet espace.
