Shingle roofing construction

Claim 2

A shingle roof construction material to be applied to a roof deck, comprising a sheet having a pair of opposed side edges, a first set of generally parallel uniformly spaced guide lines extending longitudinally of the sheet, the width of said sheet not being a multiple of the spacing between said first guide lines, whereby the distance from the end guide lines of the set to the adjacent side edges of the sheet is less than the spacing between the guide lines, and a pair of second guide lines extending longitudinally of the sheet, each second guide line being spaced inwardly of the end guide line of the first set, with the spacing between the second guide line and the end guide line of the first set being less than the spacing between said first guide lines, said second guide lines having different visual characteristics from said first guide lines and thereby being visually distinct from said first guide lines.

Claim 3

The material of claim 1, wherein said first and second guide lines are disposed symmetrically of the longitudinal center of the sheet.

Claim 4

The material of claim 1, wherein the spacing between the end guide lines of the first set and the respective side edges is equal.

Claim 5

The material of claim 1, in which the distance between one of said second guide lines and the adjacent end guide line is substantially equal to the distance between the other second guide line and the adjacent end guide line.

Claim 6

The material of claim 1, wherein each second guide line is located closer to the respective end guide line of the first set than to the next adjacent first guide line of the first set.

Claim 7

The material of claim 5, wherein the distance between the end guide lines of the first set and the respective side edge is approximately equal to the distance between said end guide line and the respective second guide line.

Claim 8

The material of claim 1, wherein said visual distinction is a color distinction.

Claim 9

The material of claim 1 wherein one of the said sets of guide lines is continuous and the other set of guide lines is interrupted.

Claim 10

A roof construction, comprising a roof deck having a lower edge, a sheet of roofing material on said roof deck and having a pair of parallel side edges with the lower of said side edges disposed in general alignment with the lower edge of the roof deck, a first set of generally parallel uniformly spaced guide lines extending longitudinally of the sheet, the width of said sheet not being a multiple of the spacing between said first guide lines, whereby the distance from the end guide lines of the set to the adjacent side edges of the sheet is less than the spacing between the guide lines, and a pair of second guide lines extending longitudinally of the sheet, each second guide line being spaced inwardly of the end guide line of the first set, with the spacing between the second guide line and the end guide line of the first set being less than the spacing between said first guide lines, said second guide lines having different visual charactetistics from said first guide lines and thereby being visually distinct from said first guide lines, and a plurality of shingles applied over the roofing material on the roof deck in a series of partially overlapping rows, said shingles having a width slightly greater than twice the spacing between said first guide lines, the upper edges of the shingles of each row being aligned with one of the first guide lines.

Claim 11

A roof construction, comprising a roof deck having a lower edge, a sheet of roofing material on said roof deck and having a pair of parallel side edges with the lower of said side edges disposed in general alignment with the lower edge of the roof deck, a first set of generally parallel uniformly spaced guide lines extending longitudinally of the sheet, the width of said sheet not being a multiple of the spacing between said first guide lines, whereby the distance from the end guide lines of the set to the adjacent side edges of the sheet is less than the spacing between the guide lines, and a pair of second guide lines extending longitudinally of the sheet, each second guide line being spaced inwardly of the end guide line of the first set, with the spacing between the second guide line and the end guide line of the first set being less than the spacing between said first guide lines, said second guide lines having different visual charactetistics from said first guide lines and thereby being visually distinct from said first guide lines, and a plurality of shingles applied over the roofing material on the roof deck in a series of partially overlapping rows, said shingles having a width slightly greater than twice the spacing between said first guide lines, the upper edges of the shingles of each row being aligned with one of the first guide lines.

Claim 12

The roof construction of claim 9, and including a second sheet of roofing material having said first and second guide lines thereon, the upper side edge of said second sheet disposed in overlapping alignment with the upper second guide line of the first sheet and the distance between the lowermost first guide line of said second sheet and the uppermost exposed first guide line of the first sheet being substantially equal to the spacing between the first guide lines of the first sheet.

Claim 13

The roof construction of claim 9, wherein said first and second guide lines are disposed symmetrically of the longitudinal center of the sheet.
