ABSTRACT:
An applicator for applying sheet material to roofs, floors and the like that includes a frame with a mount for a roll supply of the sheet material. A heater heats the lower surface of the sheet material as it is applied and a seam heater heats the upper surface of an adjacent section of previously applied sheeting material as the subsequent sheet is applied in an overlapping relationship. A roller compresses the overlapping seam until plasticized or liquid roofing material extrudes therealong to provide a visual determination that a proper seal has been formed between the adjacent sections of material.
