A corrugated metal roof shingle provided with flashing of asphalt felt associated with the courses of overlapping shingles so that any water which blows under the shingles will drain out over a lower shingle. The shingles and flashing are arranged so that the nails which secure the shingles in place pass not only through the shingles but also through three layers of asphalt felt. The corrugation of the shingle provides maximum rigidity, hail resistance and ventilation under the shingle. The shingles have a shallow channel along one side edge thereof facing outwardly or upwardly and the lower edge thereof is inturned at a shallow angle with the shingles being provided in any suitable color, etch finished or the like with the structure of the shingle enabling ease of application and low manufacturing cost as well as being highly resistant to wind and easy to cut on an angle to fit a roof valley, hips, openings and the like with the fireproof characteristics of the shingles enabling a lower insurance rate thus not only providing a roof which is economical but also one which is long lasting and durable and impervious to deleterious effects of climatic conditions.
A shingle comprising a metallic panel having substantially parallel end edges and substantially parallel top and bottom edges arranged perpendicular to the end edges, said panel including a plurality of corrugations formed therein with symmetrically curved transverse surfaces extending between the top and bottom edges, the bottom edge portion of the panel being downwardly bent along a bend line parallel to and adjacent to the bottom edge of the panel, said panel being straight from the bend line to the top edge one end edge of the panel having a shallow channel formed therein with one wall of the channel being defined by an upturned end edge on the panel, the bottom of the channel being defined by a relatively wide flat surface and the other wall of the channel being defined by a corrugation in the panel with the upturned edge of the panel being substantially equal in height to the height of the corrugations to enable the downwardly facing portion of the end corrugation on an adjacent panel to overlap the upturned end edge on the panel, said corrugations extending through the bend line with the lower edge portion of the shingle overlapping the upper edge portion of an adjacent lower shingle when installed in courses on the exterior of a building or the like.
A weatherproof covering, such as siding or roofing, for a building comprising a plurality of rows of shingles in which the lower edge of an upper row of shingles overlaps the upper edge of a lower row of shingles and the end edges of the shingles in each row overlapping with the end edges of shingles in one row being staggered in relation to the end edges of the shingles in adjacent rows, and an underlying waterproof flashing in the form of a separate strip of flashing extending throughout the length of each row of shingles with the top to bottom edge dimension of the flashing being substantially greater than the top to bottom edge dimension of each row of shingles, each of said shingles being in the form of a metal panel having corrugations extending from top to bottom edge, the lower edge portion of each shingle being downwardly bent to provide space between the lower portion of an upper row of shingles and the upper portion of a lower row of shingles to enable drainage of moisture from under the upper row of shingles and enable air circulation under the upper row of shingles for enabling the undersurface of the shingles to dry, said shingle being straight from the top edge thereof to the downwardly bent lower edge portion said strip of flashing under each row of shingles having a lower edge extending between the upper surface of the upper edge portion of a lower row of shingles and the undersurface of the lower edge portion of an upper row of shingles and terminating above but adjacent to the downwardly bent portion, the upper edge of said strip of flashing extending above the upper edge of its associated row of shingles a distance to underlie all of the next upper row of shingles and a portion of the second adjacent upper row of shingles to provide a waterproof covering for the building in underlying and partially sandwiched relation to the rows of shingles, and fastening nails extending through each of the shingles in each row at a position adjacent the lower edge thereof but above the upper edge of an underlying lower row of shingles with the fastening means extending through multiple strips of flashing.
