ABSTRACT OF THE DISCLOSURE A roofing element is disclosed of the type essentially consisting of adhesive foam plastic whose upwardly facing surface is provided with a covering plate. It has been difficult with the heretofore known roofing elements of this type to obtain an adequate stability to changing moisture and temperatures and the consequent variations in pressure under the roofing felt. The invention provides a roofing element obviating these drawbacks and being mechanically solid, and this is achieved according to the invention by making the roofing element so that the covering plate is composed of a bituminous roofing felt, whose surface facing the element is covered with gravel or pebbles, and providing a layer of glass fibre contacting said surface of the roofing felt and provided with through holes through which the adhesive foam plastic during foaming is caused to adhere to the bituminous roofing felt.
