Application January 19, 1945', SjerìalQNo.v 573,519 2 This invention relates to sheet metal roofing, and has for its principal object the provision of rooñng of this character in combination with eñi cient attachment means which will allow the or other attachment device. The extremities of the plate I3 are split so as to form three tabs at each end. The two outer tabs at each' end, in dicated at I5, are bent into alignment at right angles to the plane of the plate. The third tab roofing to be accurately and rapidly laid by in_ Ul at each' end, indicated at I5, is similarly bent experienced help; which will eliminate the neces so as to be in parallel spaced relation within the sity for holes in the roofing; and which will allow tabs I5. lateral and longitudinal heat expansion of the In applying the roofing, the strips II are laid roofing without loosening the attachment and on the sheathing I0 in parallel relation, as shown without liability of leakage. at the left of Fig.- 1.

The plates are nailed in place b-y lowing description. In the following detailed description of the invention, reference is had to the accompanying drawing which forms a part hereof. Like nu merals refer to like parts in all views of the drawing and throughout the description. In the drawing: Fig. 1 is a fragmentary perspective view illus trating the method of applying th'e improved roofing; means of suitable nails or other devices I1 pass ing through the holes I4. The nails are driven sufficiently far to bring the’plates I3 snugly against the upper edges of the flanges I2. It will be noted that the strips II are now ñrmly held against the sheathing in accurate spaced relation. They can, however, shift longi tudinally by sliding between the tabs I5 and I6 to accommodate temperature changes.
