<p>A sealing layer which is adapted to be shaped with at least one upwardly curving edge portion and to be applied adjacent to an upwardly directed surface, with the upwardly curving edge portion located adjacent to said surface, and which is designed for application to roofs as a covering layer thereon, is mouldable into shape permanence so as permanently to form the upwardly curving edge portion or portions prior to the mounting of the sealing layer and possesses such rigidity that its upwardly curving edge portion or portions retain or substantially retain their shape after the mounting of the sealing layer adjacent to the upwardly directed surface. Being, furthermore, relatively inexpensive and material-saving as it may comprise only two layers, which facilitates the sealing thereof to an existant roof covering, such a sealing layer (1) is characterised in that it comprises at least one upper layer (10) of bituminous material, preferably asphalt material, and at least one subjacent metal layer (9) with apertures (9) therein, preferably a metal netting, and that bituminous material (10a) from the upper layer (10) engages the apertures (9a) of the metal layer as a result of the material (10a) from the bituminous layer (10) having been heated and thus caused to melt into the apertures (9a) of the metal layer (9).</p> |
