Provided is a roofing underlay with a pressure-sensitive adhesive layer, the roofing underlay being capable of sufficiently exhibiting tackiness and combining antislip properties, workability, and waterproof properties of nail holes and overlaps. The roofing underlay with a pressure-sensitive adhesive layer comprises: a reinforcement sheet (6); waterproof film layers (5) disposed respectively on both surfaces thereof; an antislip layer (4) comprising a tack improver (2) and particles (3) and superposed on the surface of the waterproof film layer (5) which faces upward along the vertical direction after the roofing underlay is laid on the roof base boards; and a pressure-sensitive adhesive layer (7) comprising a synthetic rubber and a tackifier and superposed on the lower surface of the waterproof film layer (5) which faces downward along the vertical direction. |
