Description

  The present invention relates to an eaves-end structure of a modified metal roof in which a new metal roof material is spread on an existing roof material when the roof is modified.

As an eaves tip structure of this type of modified metal roof, for example, as shown in FIG. 7, a new metal roof material 42 is formed on an existing roof material 41, and an eaves side end 42 a of the new metal roof material 42 is an existing roof material 41. A new eaves arabesque (eave wrapping) 43 covering the eaves of the new metal roofing material 42 is wound at a position shifted by a predetermined distance H in the ridge side direction from the eaves side end 41a. Some are laid on the exposed portion 41b of the existing roof material 41 exposed in the direction (see Patent Document 1).
According to this, the eaves side end 42a of the new metal roofing material 42 is wound so as to be shifted from the eaves side end 41a of the existing roofing material 41 by a predetermined distance in the ridge side direction. The height of the eaves of the new metal roofing material 42 from the existing eaves eaves 44 is increased as in the case of the repair method in which the eaves side end 42a is aligned with the eaves side end 41a of the existing roofing material 41. There is nothing wrong. Therefore, even if the existing eaves 44 are not reattached when the roof is repaired, the rainwater flowing through the new metal roof plate 42 does not jump over the existing eaves 44 and does not flow down. After passing over the new eaves arabesque 43 laid on the exposed portion of the material 41, it surely flows into the existing eaves basket 44.

  In the above-described conventional eaves structure of a modified metal roof, when the newly installed eaves arabesque 43 is fixed to the existing roofing material 41, the new eaves arabesque 43 self-drills to the roof mounting portion 43a covering the exposed portion 41b of the existing roofing material 41. A screw 45 is driven in and fixed to the existing roofing material 41, and a waterproof sheet 46 is attached to the driving site of the self-drilling screw 45 so as to cover the screw head. However, since the place where the self-drilling screw 45 is driven is the back side of the end of the eaves side of the new metal roofing material 42 and rainwater from the eaves is likely to enter, the waterproof sheet 46 is attached. It could not be said that waterproofing was enough. Moreover, when the notch part 47 is formed in the back surface part of the eaves side edge part of the new metal roofing material 42 in order to avoid contact | abutting with the head part of the self-drilling screw 45, the new metal roofing material 42 is made into the front of the eaves side. Since the cutout 47 can be seen well, the aesthetic appearance of the repaired roof is likely to be impaired.

  The object of the present invention is as described above, wherein the eaves end of the repaired metal roof is sown so that the eaves side end of the new metal roofing material is shifted by a predetermined distance in the ridge side direction from the eaves end side of the existing roofing material.
