A roofing plate 10, such as a corrugated, interlocking tile, has an upper side surface which is provided with a sealing strip 27 arranged extending across the corrugations of the roofing plate at the upper edge thereof. The sealing strip 27 is constituted by a strip of upright synthetic fibres, such as a combination of polyamide fibres of a length of 3 mm and of a length of 5 mm and of a thickness of 0.05 mm (22 dtex). The strip 27 is adapted to provide a barrier when it is clamped between the upper side surface of the roofing plate and the lower side surface of an adjacent roofing plate, and the barrier permits the passage of air from the inside of a loft formed below the roofing plates and from the outside into the loft and further permits the passage of water from the inside of the loft out and blocks the passage of water and dust from the outside into the loft. A further sealing strip 29 may be arranged along one of the roofing-plate side edges extending along the corrugations thereof. The sealing strip 27 may be provided as a single component which can be arranged on the upper or lower side surface of the roofing plate prior to the arrangement of the roofing plate overlapping another roofing plate on the roof and may comprise a base layer having a glue layer and a protective paper, if desired. The sealing strip 27 may be applied to the roofing plate 10 in an electrostatic application process (flock application) and retained in a glue layer of the roofing plate. <IMAGE> |
