ABSTRACT:
A self contained apparatus is utilized for direct movement on and across a roof surface to lay on the roof surface a continuous sheet or roofing material being removed from a roll guided at each of its ends by this apparatus, and being heated, before being removed, by a heating assembly pivotally supported by the apparatus and pivotally adjusted, so the distance between the roll and the heating assembly is maintained. An inclined A frame of the apparatus has a handle at its apex, and bottom opening slots at its lower ends to fit over the ends of a shaft on which the roll of roofing material is positioned. There is a depending wheel assembly below the handle serving to complete the triangular support of this self contained apparatus. The inclined A frame is pivoted about the wheel assembly to clear the bottom opening slots from the shaft ends and vice versa, when a roll of roofing material is being supplied, withdrawn, and/or adjusted to a different set of slots. Accessories, if required, are added such as a heat shield located on the inclined A frame between a gas tank and the burners or heaters. Also retractable locks are used to keep the shaft ends in place at the slots at the bottom of the inclined A frame. During the use of this self contained apparatus, the cantilevered weight thereof essentially directly supplements the weight of the roll of roofing material to very effectively sealably press the heated sheet of roofing material accurately in place on the roof surface.
