Abstract
ABSTRACT
Shingle simulating laminated flat strip sheet material for application in horizontally extending weatherproof interlocked courses, comprising a thin, flexible underlying plastic film having a self sealing asphalt mastic coating layer and a mineral granule front surface layer.
The strip material has on each of its opposite faces a longitudinally extending groove adjacent to and spaced from opposite ones of its longi-tudinally extending edges, so that the strip material is foldable along the grooves around the edge of an adjacent folded strip edge.

Description
This invention relates to roofing, siding and the like and, more particularly, to flexible, shingle simulating strip material for application in horizontally extending interlocked courses.
There has long been a need in the art for an attractive, shingle simulating strip material, which may be manufactured at relatively low cost, which can be rolled up for shipment, and which can be quickly and easily , applied by inexperienced labor by stapling or nailing to an underlying substrate to provide a weatherproof covering. Although attempts have been made over the years to provide such a material, they have all proved to be v 10 deficient in one respect or another.
According to the present invention there is provided a first i laminated strip material adapted to be laid in hori~ontally extending weather-proof interlocked courses on a roof deck and secured thereto by concealed , fastening means, said first laminated strip material comprising: a thin f, underlying plastic base sheet of at least about 1 mil thickness; a self-sealing asphalt mastic coating layer having a thickness of about 0.050-0.100 inches adhered to the front face only of said base sheet, the rear face of said base sheet forming the rear face of said laminated strip material; a mineral granule front surface layer having a thickness of about 0.030 to 0.050 inches adhered directly to said asphalt mastic coating layer, said mineral granule layer forming the front face of said laminated sheet material;
said laminated strip material having on its front face a single longitudinally extending groove adjacent to and spaced from one of its longitudinally extending edges; and on its rear face a single longitudinally extending groove adjacent to and spaced from the other of its longitudinally extending edges, said grooves extending for a width at least about equal to the total thickness of said strip material and for a depth of at least about one-half ' , ---ti12~3 .
of the thickness of said strip material; whereby said first laminated strip material is foldable along said grooves for 180 degrees around the edge of a second adjacent strip of said laminated strip material without damaging said laminated strip material, for 180 degree fold interlocking of the edges of adjacent strips of said strip material to conceal said fastening means, with said fastening means extending through said first strip material and into said roof deck for securing the strip to the deck, said asphalt mastic sealing material automatically sealing around the shanks of said fastening means and preventing the passage of moisture through holes formed in said first laminated strip material by the fastening means.
This material which can be applied by nailing will self seal around the nail shanks. It may be applied so as to conceal the nail heads within the interlocked edges of horizontally extending courses.
The strip material may be made of the exact width of a roof to be `~ covered so to avoid end joints.
- The present material can be quickly and easily applied by in-experienced labor by nailing it to a substrate to provide a weatherproof covering of horizontally extending courses with interlocked edges and one which is impervious to ice and wind damage problems.
The laminated strip material is preferably foldable along the grooves at a temperature at least as low as 20 degrees F without damaging the laminated strip material. The front face of the laminated material may have a plurality of transversely extending shingle simulating appearance stripes.

Referring to the drawings, the novel laminated flat strip gener-ally designated 10, has a thin, flexible underlying plastic film 12, a self sealing asphalt mastic coating layer 14 adhered to the front face only of film 12 and a mineral granule front surface layer 16 adhered directly to the asphalt mastic coating layer 14. The rear face of fil~ 12 forms the rear face 18 of strip 10 and the front surface of mineral layer 16 forms the front face 20 of strip 10. On its front face 20, strip 10 - has a single longitudinally extending groove 22 adJacent to and spaced from its longitudinally extending edge 24 and on its rear face 18, strip 10 has a single longitudinally extending groove 26 adjacent to and equally spaced from its other longitudinally extending edge 28. As hereinafter more fully sxplained~ grooves 22 and 26 function as guide and hinge lines during application of strips 10 in horizontally interlocked courses.
To enhance its shingle simulating appearance, strip 10 may have, on its front face 20, a plurality of transversely extending shingle sim-ulating appearance stripes 30, which preferably have random spacing.
