Description

  The present invention relates to a roof material repair material for repairing cracks in a plate-like roof material laminated and fixed to a roof, and an edge cutting material.

  A plate-like roof material 7 also called a residential decorative slate as shown in FIG. 9 is used for the residential roof. The shape of the most used roofing material is generally a pentagon having a vertical length of 410 mm (longest part), a horizontal length of 910 mm, and a vertical length of 330 mm, and a thickness of about 5 mm. Of course, flat roof tiles are also included in the plate-like roofing material.

  Moreover, the roofing material 7 is laminated | stacked toward the ridge from the eaves side of a roof, and is laminated | stacked and fixed to a field board. Although the fixing of the roofing material 7 to the road plate differs depending on the manufacturer, many roofing materials are provided with a plurality of nail holes 7b at positions 220 mm to 240 mm from the bottom, and nails 8 are driven into the nail holes 7b. The roof material 7 is fixed to the roof rail. The oblique line area in the figure is exposed to the outside, and is about 180 mm. Accordingly, the nail hole 7b is formed at a position of 40 to 60 mm from the upper end of the exposed portion.

  Conventionally, asbestos has been mixed in the composition of many roofing materials. At present, it is prohibited to mix asbestos into the roofing material, but asbestos-containing roofing material is used for roofs constructed several years ago, and there are still many that remain on the roof.

  Due to asbestos health problems, the same products that are currently being sown have been discontinued and often cannot be replaced even if the roofing material cracks due to aging. Moreover, even if it replaces | exchanges for another roof material, the special condition is required for replacement | exchange of a roof material from the health problem of asbestos mixed in the roof material, and the present condition is expensive.

  Therefore, cracks are often repaired with fillers. However, in the repair using the filler, the filler has a viscosity, and the filler may not completely penetrate the cracked area and may pass rainwater. In addition, with the passage of time, the filler often deteriorates and cracks often occur again, and rainwater penetrates into the cracks, which may corrode the roof.

  On the other hand, the slate roofing material 7 is said to require maintenance (painting) in about 10 years after installation. At that time, the roof material of the slate may be broken. The repair was also a problem for the above reasons. For this reason, the inventor has previously developed a repair material for roofing materials (Patent Documents 1 and 2).

  However, there is a need for a repair material that can be constructed more simply and at a lower cost, and that follows durability and deterioration of the roofing material (expansion of the gap due to warping of the roofing material).

  In addition, after painting the slate roofing material 7, in order to secure the air permeability of the overlapping portion of the upper and lower roofing materials 7, 7, the edge blocked by the coating film has been cut. In order to facilitate the edge cutting work, edge cutting materials for roof materials have been developed (Patent Documents 3 to 6).

  However, they do not have a crack repairing function and cannot sufficiently follow the deterioration of the roofing material (expansion of the gap between the upper and lower roofing materials 7 and 7 due to the warping of the roofing material).
