Roof tile

A method of fabricating a roof-covering element out of molded cellulose impregnated with bitumen for roofing. In a first step, an element, preferably of cellulose, is made by hot compression molding in a mold, in a second step, once the element has a dry matter content of at least 60% when extracted from the mold, the element is covered in a pigmented varnish and dried, and in a third step, once the element has a dry matter content of at least 98%, the element is impregnated with hot bitumen. Specific operating conditions are given. The covering elements include in particular a ridge side portion, a ridge cap, a ridge-covering kit, a fillet or curb, and a hip.

Building verge

A molded ridge tile () made of bitumen-impregnated cellulose for covering a roof, and a method of applying the ridge tile to the roof. The ridge tile has an elongate shape in the length direction and includes transversely a downwardly concave symmetrical central portion () that is extended laterally and symmetrically on either side by two plane flanges () sloping laterally downwards beside the central portion, the flanges being carried by two planes that intersect with a downwardly facing internal angle between the flanges, the flanges being designed to be applied flat against two flat slopes of an upside-down V-shaped roof along the angular connection between the slopes, the slopes defining between them a determined ridge angle. In the absence of deformation stress, the internal angle between the flanges is 106 degrees&#xb1;10 degrees, i.e. a flange angle relative to the horizontal of 37 degrees&#xb1;5 degrees.
