The anchor piece J8 comprises a base to h P d behind e Plate 2 after which the portion 2| having at one end. a downwardly exflashing t p 5 is placed in DO-SitiOIIVWith the tending flange 22 a d t th ppogite end an flange 3'! thereof positioned in the channelway 33 upwardly extending flange 23. Thebase 2| prefof the reglet piece 30 and with the face portion 36 45 erably tapers and has an aperture 24 therein. thereof extending w w d Over the t p Theflange 23 includes a threaded aperture 25 tion 40 of the roofing material. The bolts E9 of to receive the threaded portion of the bolt 19. the anchor-member I! are then tig d p The clamping plate 20 has: an aperture 26 thereby drawing the upp p 21 o engage- 0 therein in which the bolt I9 is positioned and the ment with. the bricks and the lower lip 28 into upper and lower ends of the clamping plate. are engagement with the face 36 of the flashing 35. preferably arcuately bent 'to form engaginglips Upon further tightening of the bolts IS the lip 28 21 and 28, respectively. The aperture 26. inthe of the clamping plates moves the face 39 of the clamping plate 20 is preferably positioned. nearer flashing strip into tight engagement with the porto the upper end thereof than the lower end.: tion 40 of theroofing material thereby clamping the portion 40 tightly against the parapet. By providing the angular portion 38 on the flashing strip the lower end thereof tightly engages the portion 40 of the roofing material.

In Fig. 5 I have shown a detail of my novel anchor bolt and indicated it generally at 4|. As shown the bolt 4| comprises a shank 42 having an enlarged rectangularly shaped head 43 integral therewith at one end and a threaded portion 44 adjacent the opposite end. The threaded end of the shank 42 is preferably slotted as indicated at G5. The head 43 is sharpened as indicated at 46 to provide diagonally opposed cutting points 41;:

The anchor bolt 4| is adapted to beused in place of the anchor member I! when replacing the roofing material of an old building. When using a bolt 4| an aperture 48 is. drilled in the mortar joint M of a size sufficient to insert therethrough the head 43 of the bolt when the head is turned with its length horizontal. The aperture 48 isdrilled into the mortar joint l4 and through the mortar joint It. The bolt 4| is then positioned in the aperture 48 with the head '43 thereof positioned in the mortar joint l6 and thethreaded end 44 projecting beyond the face of the bricks I3.

The flashing strip is then placed-in position with the flange 31 thereof positioned in the previously formed old reglet gash 49 and then a clamping plate 28 is positioned on'the bolt and a nut 58 is positioned on the threaded portion 44 of the bolt. A suitable tool is then positioned in the bolt slot 45 and the bolt turned ninety (90) degrees. As the bolt is thus turned the head 43 thereof cuts into the mortar of the joint IE to a position wherein the length of the head is vertical in which position the head cannot be withdrawn through the aperture 48. Thereafter the nut 50 is tightened up against the clamping plate 2i] which thereupon firmly clamps the flashing and roofing material to the parapet as previously described.

From the foregoing description it will be apparent that I have provided a novel roofing construction which is simple in construction and highly eflicient in use.
