It Will be noted, on referring toFg. 1,

This requires careful ends of adjacent/strips are overlapped when\V measurements on the part of the roofer and laid in a row, to form a course, as seen in` soniowhaty slows down thespeed of laying Fig-2. Furthermore, the distance (y) from the, roof The, second course, as Well as the the Upper Tight-hand COIHQI a2 t0 the nGaI'BStf succeeding courses, must be laid that the slit 10 is equal to the width, measured horitongnes ot' each strip come exactly midway ZOntally, of a slab 14, or .in other Words, to I between the tongues of the strips of the the distance between adjacent tongues 13.

e ends 15 and 16 are parallel, the lap is or uniform width throughout. Furthermore, when the ends are'lapped as described, the joints wiil fall in such'position as to be completely cov ered by portions oi the strips of the next lower and the nextupper courses. For example, on referringf'to Fig. 4 it will be noted tllatghe. joint between the two stri s ofthe intermediate @ourse B is complete y concealed'oif portions of the strips of the first course A and the third course C. The strips are so designed that each oneniustoverlap the preceding one in tl'ie right Way. -for any reason the overlapping is carried out improperly, then the error would be selfevident, since the edge 16 would extend beyond the tongue, and being visible could be 'corrected immediately.
What claim is:
1. A. roofing strip of rhomboida'l shape having tongues Aand intervening slabs along one of the longer edges, the tongue nearest Aone end being spaced from said end a dis neeeree tance defining the proper extent of the overlap of adjoining strips of acourse Whenieid, the tongue nearest the opposite end being spaced from said opposite end a 'dist-ance substantially equal to the width of a slab measured in the direction of length of the strip, the opposite longer edges being oiiset the tongue nearest the opposite end being if' spaced from said opposite end a distance substantially equal to the Width of a slab measured in the direction of length of the strip.
