Strip shingle of improved aesthetic character

Abstract

Abstract A LAMINATED, MINERAL-SURFACED, ASPHALT STRIP SHINGLE, WHICH, WHEN LAID IN COURSES ON A ROOF, SIMULATES THE IRREGULARITY AND ATTENDANT SHADOW EFFECTS FOUND IN WOOD SHINGLES, WHILE COMPLYING WITH UNDERWRITERS'' LABORATOREIS, INC. STANDARDS FOR THE FIRE RETARDANT ASPHALT SHINGLES. A RECTANGULAR "MONOTAB" BASE LAMINA AND AN "APORN OVERALY" LAMINA ARE ADHERED TOGETHER WITH ROOFING ASPHALT. THE OVERLAY LAMINA IS OF THE SAME LENGTH AS THE BASE LAMINA AND HAS A PLURALITY OF APPROXIMATELY RECTANGULAR TABS OF VARYING WIDTHS AND LENGTHS, SOME OF WHICH PROJECT BEYOND THE BOTTOM EDGE O TH BASE LAMINA, AND IS LATERALLY OFFSET WITH RESPECT TO THE BASE LAMINA BY A SMALL AMOUNT, SO AS TO COVER THE BUTT JOINT BETWEEN ADJACENT BASE LAMINAE IN THE SAME COURSES. VERTICAL ALIGNMENT MARKS ARE PROVIDED, SUCH THAT THE BASE LAMINA OVERHANGS THE TOPS OF THE CUT-OUTS BETWEEN TABS OF THE OVERLAY LAMINA IN THE NEXT LOWER COURS. A PLURALITY OF HORIZONTAL LAYING MARKS, DIFFERENTLY SPACED, ARE PROVIDED TO CREATE A PROGRAM IN LAYING, WHICH INSURES THE AVOIDANCE OF REPETITIVE OR DIRECTIONAL PATTERNING. D R A W I N G
