To process a gap generated between a roof free end at a terrace of a building additive construction constructed without fixing to a building frame and the building frame effectively and with better appearance and to prevent immersion of rainwater as much as possible.SOLUTION: A roof free end of a terrace 1 is installed with about 10 cm apart from a building frame, an oscillation gap B for allowing an oscillation or a bend of the roof 12 due to gate load of wind pressure or snow load between the roof free end and the building frame A is arranged and a wide tabular closing member 4 is arranged protruding upward by an extrusion molding material of elastomer from the roof free end to the building frame A side as well and by elastic pressure contact of its tongue shape tip 43 to the building frame A freely slidable in vertical direction, the immersion of rainwater between the building frame A and the terrace 1 is prevented by the closing member 4 as much as possible. As the closing member 4 has a high elasticity and extensibility, it has a durability without being damaged.SELECTED DRAWING: Figure 4
