  However, in the conventional roof structure, a water blocking block formed of rubber or the like is used as a plugging material for closing the end of the rain gutter recess, and this water blocking block is made into a rain gutter recess with a wet sealing material or the like. The use of a water-stopping structure that is bonded and fixed results in inconveniences such as requiring time and effort for the bonding and fixing work of the water-stopping block, and variations in water-stopping performance depending on the skill level of the operator. Moreover, although the eaves in the conventional roof structure are supported by the front beam via an attachment along the longitudinal direction, the longitudinal ends are not supported by the side beam, and the vertical direction such as wind pressure is not supported. There is also the inconvenience that it is easy to bend with respect to force.

  An object of the present invention is to provide a roof and a roof construction method capable of ensuring water-stopping at the edge of the fence and enhancing the attachment rigidity of the fence.

According to the present invention described above, the watertight material is sandwiched and fixed between the edge of the heel member and the fixing member, so that the watertight material can be brought into close contact with the heel member in a pressed state. The water stop performance can be secured. At this time, as a fixing method of the fixing member to the flange member, any method such as screwing a screw or engaging a pin or an engagement piece can be used, and a conventional wet sealing material is used. Compared with the method, the labor and time can be reduced, and a constant water stopping performance can be ensured regardless of the skill level of the operator.
Further, by fixing the connecting portion of the fixing member positioned outside the cross-sectional outer shape of the flange member to the side support member, the flange member can be supported by the side support member via the fixing member. Deformation against wind pressure or the like can be prevented by increasing the supporting strength and rigidity of the member. In this way, by increasing the mounting rigidity of the end portion of the flange member, it is possible to prevent deterioration of the water stop portion due to repeated deformation, and to improve water stop performance.

At this time, in the roof according to the present invention, the fixing member is fixed to the edge of the saddle member by a first fixing tool penetrating the fixing member from the opposite side of the saddle member, and the first fixing It is preferable to be fixed to the side support member by a second fixing tool that penetrates the connecting portion of the fixing member from the side opposite to the tool.

In the covered state, the fixing work can be easily performed by penetrating the connecting portion of the fixing member from the opposite side and fixing the second fixing tool to the side support material, thereby improving workability. Can be made. And the external appearance design property of a roof can be made favorable because a 1st fixing tool is covered by a side support material.

Furthermore, in the roof of the present invention, on the opposite side of the roof surface material across the flange member, a front support material is provided that is connected to intersect with the side support material, and is provided on the side surface of the front support material. It is preferable that the said eaves member is being fixed directly or via the attachment member.
According to such a structure, the support strength and attachment rigidity of a collar member can further be improved by fixing a collar member to a front support material.

On the other hand, the roof construction method of the present invention is a roof construction method comprising a roof surface material installed with a water gradient and a gutter member provided along the lower edge of the roof surface material. A watertight material covering the side of the water receiving portion is brought into contact with at least one end edge side of the flange member formed to have a groove-shaped water receiving portion opened upward, and the watertight material The fixing member is fixed to one end edge of the saddle member with the one end edge side facing the side support member that supports the side end edge of the roof surface material, and the saddle member is disposed.
