- an elongated, stiff blade having a bottom edge having a plurality of evenly spaced serrations throughout, said blade having front and back sides,
- a support bar attached to said front side of said blade,
- a hood attached to said back side of said blade and having a portion curving above and in front of said blade,
- an elongated blade bracket having two ends, said blade bracket being L-shaped in transverse cross section and overlying and attached to said hood such that said hood is sandwiched between the blade bracket and the back side of said blade,
- at least two braces attached to said blade bracket,

A spreader for spreading cold-coat roofing tar into a plurality of generally uniform, substantially parallel ribbons over a section of a roof in a generally forward motion, the spreader comprising:
- (a) a hooded blade assembly, including:
- (a.1) an elongated, stiff blade having a serrated bottom edge with a plurality of serrations evenly spaced therealong, said blade having forward and rearward sides;
- (a.2) an elongated forward blade-clamping member positioned forward of the forward side of the blade and extending along a lengthwise direction of the blade with the serrated bottom edge of the blade projecting below a lower edge of said blade-clamping member;
- (a.3) an elongated rearward blade-clamping member positioned rearward of the rearward side of the blade and extending along the lengthwise direction of the blade with the serrated bottom edge of the blade projecting below a lower edge of said blade-clamping member;
- (a.4) clamping means for urging the forward and rearward clamping members together to clamp the serrated blade between the clamping members;
- and
- (a.5) an elongated hood attached to at least one of said clamping members, the hood having a curved portion curving above and forward of the blade;
- (b) a handle bracket attached to the hooded blade assembly at a position on a rearward side of the assembly approximately centrally of the rearward side in a lateral dimension and a vertical dimension;
- (c) at least two handle braces, each handle brace being attached at one end to the handle bracket and at an opposing end to the rearward side of the hooded blade assembly approximately centrally of the rearward side in a vertical dimension and spaced apart laterally from the handle bracket;
- and
- (d) a handle attached to the handle bracket.
