Description

The present invention relates to a repair structure for an existing roof, and more particularly to a repair structure for repairing a roof including a roof with good workability without removing (removing) the existing roof member and the existing roof material.

Conventionally, when renovating a roof including keraba, all existing roofing materials and existing keraba members are removed, and if necessary, a waterproof sheet such as asphalt roofing is installed on the base, and new (repaired) keraba members are installed on the sheet. And new (repair) roofing materials were to be constructed. However, it takes a lot of cost and time to remove the existing roofing material and the existing roofing material, and a large amount of residual material is generated. In recent years, labor shortage has become a big problem in the future. It is becoming difficult to renovate the roof without considering the labor shortage.

To solve such a problem, a roofing repair structure is known which can shorten the construction period by constructing a new (repairing) roofing material without removing the existing roofing material and the existing roofing material. For example, Japanese Patent Application Laid-Open No. 8-049365 (Patent Document 1) discloses a repair structure for repairing a gable-side portion of an existing roof using a two-member fluff and a stepped roofing material.

The fluffy renovation structure disclosed in Patent Document 1 is a structure for refurbishing the fluffy portion of an existing new tile roof, in which a roofing material is formed on the existing roof in a stepped roof shape by using a board-shaped lining material. At the same time, a horizontal fixed piece, a protruding piece in which the middle of the fixed piece is projected upward, an engaging groove formed in a substantially U shape at the end of the fixed piece, and the tip of the engaging groove are hung downward. The hanging piece and the locking base formed in a substantially L-shaped cross section are abutted and fixed to the side edge of the existing roof, and the fixed piece is brought into contact with the fluffy end face of the existing roof and the fixing piece is existing by a fixing tool such as a nail. The roofing material is roofed while being fixed to the roof and the end portion of the backing material is substantially in contact with the protruding piece, and the decorative surface edge of the roofing material protrudes from the protruding piece toward the engaging groove side. The edge of the roofing material has at least a decorative surface portion having substantially the same shape as the decorative surface of the roofing material, and one end edge of the decorative surface portion in the width direction protrudes downward, and a ridge-shaped tongue piece is provided at the tip. A decorative cap consisting of a side cover piece and an insertion edge that protrudes downward in the middle of the width direction of the decorative surface portion and has an engaging protrusion at the lower end is fitted into the locking groove of the locking base, and the insertion edge is engaged. It is characterized by stopping and covering the decorative surface of the roofing material with the decorative surface portion.
