ABSTRACT:
An integrally formed, interlocking siding or roofing strip assembly for covering a surface of a building. The strip includes a central panel, a lower spacing element, an upper assembly for operatively engaging the lower spacing element of another strip to be installed so as to interlock the strips in a partially overlapping manner, one above the other. The top end portion of the strip is provided with a plurality of generally vertically aligned corrugations having alternate ridge and valley portions. Fastening elements penetrate some of the valley and/or ridge portions to securely anchor the strips to the building surface. The corrugations serve (1) to compensate for expansions and contractions caused by aging and/or weather variations and (2) to continually bias the fastening elements to tightly anchor the strip to the surface in a spring-like manner thereby preventing the strips from becoming loose and eliminating noise and rattling. The corrugations may be provided with a plurality of apertures for operatively receiving the fastening elements and the thickness of the top end portion which is corrugated may be less than the thickness of the central panel to facilitate the compensation function of the corrugations.
