ここで、既設の屋根材を覆うように新設の屋根材を配置する特許文献１に記載のような屋根構造を有する屋根に、太陽光パネルを取り付けたい場合がある。しかし、後から取り付けた新設の屋根材に太陽光パネルを固定するための固定台を取り付ける場合には、新設の屋根材の取り付けの強度を確保しないと、固定台を安定して取り付けることが難しくなり、太陽光パネルを固定するための固定台の取り付けの強度が弱くなる可能性がある。 Here, there is a case where it is desired to attach a solar panel to a roof having a roof structure as described in Patent Document 1 in which a new roofing material is arranged so as to cover the existing roofing material. However, when installing a fixing base for fixing the solar panel to the newly installed roofing material that was installed later, it is difficult to stably install the fixing base unless the strength of the installation of the new roofing material is secured. Therefore, the strength of mounting the fixing base for fixing the solar panel may be weakened.

If the structure is such that the base is attached, the fixed base can be attached stably. On the other hand, it may be necessary to attach a fixing base to the step of the overlapping portion of a plurality of slate. When attaching the fixing base to the steps of multiple slate, it becomes difficult to stably attach the fixing base to the steps of multiple slate, and the mounting strength of the fixing base for fixing the solar panel may be weakened. There is.
Therefore, in a roof structure in which a new roofing material is arranged so as to cover an existing roofing material, it is desired that the solar panel can be stably installed when the solar panel is installed.

ここで、本発明（第２屋根材４の働き長さを調整した場合）と、第２屋根材４の働き長さを調整しない場合（未調整の場合）とを比較することで、本発明について詳細に説明する。図６は、第２屋根材４の働き長さが未調整の場合におけるルーフ板４１の配置を示す断面図であって、（ａ）は、支持金具３が配置されている部分における断面図であり、（ｂ）は、支持金具３が配置されていない部分における断面図である。 Here, the present invention is made by comparing the present invention (when the working length of the second roofing material 4 is adjusted) and the case where the working length of the second roofing material 4 is not adjusted (when not adjusted). Will be described in detail. FIG. 6 is a cross-sectional view showing the arrangement of the roof plate 41 when the working length of the second roofing material 4 is not adjusted, and FIG. 6A is a cross-sectional view of a portion where the support metal fitting 3 is arranged. Yes, (b) is a cross-sectional view of a portion where the support metal fitting 3 is not arranged.

所定長さの第２屋根材４の複数のルーフ板４１を用いて第２屋根材４を構成する場合において、第１屋根材１３のスレート１３１のスレート側働き長さＬ１を整数倍した長さと、第２屋根材４のルーフ板４１のルーフ板側働き長さＬ２とが異なる長さである場合がある。このような場合において、第２屋根材４の働き長さが未調整の場合には、例えば、働き長さが未調整の場合の第２屋根材４の複数のルーフ板４１は、図６の（ａ）に示すように、複数のルーフ板４１を隙間なく並べて配置すると、第２屋根材４の複数のルーフ板４１の未調整働き長さＬ０は、第１屋根材１３の２枚のスレート１３１の働き総長さＬＴ（＝Ｌ１×２）よりも長く形成される（Ｌ０＞ＬＴ）ことがある。ここで、図６の（ｂ）に示すように、第２屋根材４のルーフ板４１の軒側端部接続板部４３は、支持金具３の収容凹溝部３０（溝部）に収容された状態である。 When the second roofing material 4 is constructed by using a plurality of roof plates 41 of the second roofing material 4 having a predetermined length, the length is obtained by multiplying the slate-side working length L1 of the slate 131 of the first roofing material 13 by an integral multiple. , The roof plate side working length L2 of the roof plate 41 of the second roof material 4 may be a different length. In such a case, when the working length of the second roofing material 4 is not adjusted, for example, the plurality of roof plates 41 of the second roofing material 4 when the working length is not adjusted are shown in FIG. As shown in (a), when a plurality of roof plates 41 are arranged side by side without a gap, the unadjusted working length L0 of the plurality of roof plates 41 of the second roof material 4 is the two slate of the first roof material 13. It may be formed longer than the total working length LT (= L1 × 2) of 131 (L0> LT). Here, as shown in FIG. 6B, the eaves-side end connection plate portion 43 of the roof plate 41 of the second roofing material 4 is accommodated in the accommodating recessed groove portion 30 (groove portion) of the support metal fitting 3. Is.

この場合には、支持金具３を支持する複数の固定台２２のうち、例えば、図６の（ａ）における屋根の棟側から１つ目の固定台２２を、第１屋根材１３の段差１４以外の部分のスレート１３１の上面に配置したとしても、ルーフ板４１の軒側端部接続板部４３が支持金具３の収容凹溝部３０に収容した状態（図６の（ｂ）参照）においては、棟側から２つ目の固定台２２は、第１屋根材１３の段差１４に対して屋根の傾斜方向の軒側にΔＬ（＝Ｌ０−ＬＴ）の長さだけずれて配置されることになる。そのため、棟側から２つ目の固定台２２は、図６の（ａ）及び（ｂ）に示すように、段差１４を跨いで配置される。 In this case, among the plurality of fixing bases 22 that support the support metal fittings 3, for example, the first fixing base 22 from the roof ridge side in FIG. 6A is the step 14 of the first roofing material 13. Even if it is arranged on the upper surface of the slate 131 other than the above, the roof plate 41 is housed in the housing recessed groove 30 of the support metal fitting 3 (see FIG. 6B). The second fixing base 22 from the ridge side is arranged on the eaves side in the inclination direction of the roof with respect to the step 14 of the first roofing material 13 by a length of ΔL (= L0-LT). Become. Therefore, the second fixing base 22 from the ridge side is arranged so as to straddle the step 14 as shown in FIGS. 6A and 6B.

より詳細には、図６の（ａ）に示すように、本実施形態においては、第２屋根材４のルーフ板４１の屋根の傾斜方向の未調整働き長さＬ０は、例えば、Ｌ０＝３６８ｍｍである。また、第１屋根材１３のスレート１３１の段差上面１４０の屋根の傾斜方向のスレート側働き長さＬ１は、例えば、Ｌ１＝１８２ｍｍであり、第１屋根材１３の２枚のスレート１３１の段差上面１４０の屋根の傾斜方向の働き総長さＬＴ（＝Ｌ１×２）は、ＬＴ＝Ｌ１×２＝１８２ｍｍ×２＝３６４ｍｍである。 More specifically, as shown in FIG. 6A, in the present embodiment, the unadjusted working length L0 of the roof plate 41 of the second roofing material 4 in the inclination direction is, for example, L0 = 368 mm. Is. Further, the slate-side working length L1 of the step upper surface 140 of the slate 131 of the first roof material 13 in the inclination direction of the roof is, for example, L1 = 182 mm, and the step upper surface of the two slate 131 of the first roof material 13 The total working length LT (= L1 × 2) of the roof of 140 in the inclined direction is LT = L1 × 2 = 182 mm × 2 = 364 mm.

ここで、複数のルーフ板４１を隙間なく屋根の傾斜方向に並べて配置すると、第２屋根材４のルーフ板４１の傾斜方向の未調整働き長さＬ０（３６８ｍｍ）が、２枚のスレート１３１の段差上面１４０の働き総長さＬＴ＝Ｌ１×２（３６４ｍｍ）よりも長いため、その差ΔＬ（４ｍｍ）（＝Ｌ０（３６８ｍｍ）−ＬＴ（３６４ｍｍ））ずつ、ルーフ板４１の設置位置が傾斜方向にずれていく。そのため、ルーフ板４１の設置位置がずれることにより、固定台２２の位置は、図６の（ａ）に示すように、ΔＬ（４ｍｍ）ずつ、屋根の傾斜方向の軒側にずれる。これにより、図６の（ａ）及び（ｂ）に示すように、棟側から１つ目の固定台２２を、第１屋根材１３の段差１４以外の部分のスレート１３１の上面に配置したとしても、棟側から２つ目の固定台２２は、段差１４を跨いで配置されることになる。そして、このルーフ板４１の設置位置が傾斜方向にずれることが繰り返されることで、第１屋根材１３の段差１４に対する固定台２２の設置位置が一定せずに、固定台２２は、段差１４を跨いで配置されたり、段差１４を跨がないで配置されたりする。 Here, when a plurality of roof plates 41 are arranged side by side in the inclination direction of the roof without a gap, the unadjusted working length L0 (368 mm) of the roof plate 41 of the second roof material 4 in the inclination direction of the two slate 131. Since the total working length of the step upper surface 140 is longer than LT = L1 × 2 (364 mm), the installation position of the roof plate 41 is tilted by the difference ΔL (4 mm) (= L0 (368 mm) -LT (364 mm)). It shifts. Therefore, as the installation position of the roof plate 41 shifts, the position of the fixing base 22 shifts to the eaves side in the inclination direction of the roof by ΔL (4 mm) as shown in FIG. 6A. As a result, as shown in FIGS. 6A and 6B, it is assumed that the first fixing base 22 from the ridge side is arranged on the upper surface of the slate 131 in the portion other than the step 14 of the first roofing material 13. However, the second fixing base 22 from the ridge side is arranged so as to straddle the step 14. Then, the installation position of the roof plate 41 is repeatedly shifted in the inclined direction, so that the installation position of the fixing base 22 with respect to the step 14 of the first roofing material 13 is not constant, and the fixing base 22 makes the step 14 It may be arranged straddling, or may be arranged without straddling the step 14.

このように、第２屋根材４の複数のルーフ板４１の働き長さが調整されていないと、図６の（ａ）及び（ｂ）に示すように、ルーフ板４１の設置位置は、固定台２２の第１屋根材１３の段差１４に対する位置が屋根の傾斜方向にずれることにより、固定台２２の設置位置が一定せずに、第１屋根材１３の段差１４を跨ぐように配置されることがあった。これにより、既設の第１屋根材１３の段差１４を跨いで配置された場合には、固定台２２の軒側が下方段差面１４２側に転げてしまうなどして、安定して設置できない場合があった。 As described above, if the working lengths of the plurality of roof plates 41 of the second roof material 4 are not adjusted, the installation positions of the roof plates 41 are fixed as shown in FIGS. 6A and 6B. Since the position of the base 22 with respect to the step 14 of the first roof material 13 shifts in the inclination direction of the roof, the installation position of the fixed base 22 is not constant and is arranged so as to straddle the step 14 of the first roof material 13. There was something. As a result, when the existing first roofing material 13 is arranged so as to straddle the step 14, the eaves side of the fixing base 22 may roll to the lower step surface 142 side, and stable installation may not be possible. It was.

これに対して、本発明においては、図４及び図５に示すように、複数のルーフ板４１は、それぞれ、ルーフ板４１の一部が収容凹溝部３０に配置された状態で、第１屋根材１３の傾斜方向において、ルーフ板側働き長さＬ２が、スレート側働き長さＬ１（第１働き長さ）の２倍（整数倍）となるように、隣接するルーフ板４１の重なり部分の長さを調整して配置される。
本発明の太陽光パネル取付構造１を施工する場合には、複数のルーフ板４１を、それぞれ、第１屋根材１３の傾斜方向において、ルーフ板側働き長さＬ２が、スレート側働き長さＬ１の整数倍となるように、隣接するルーフ板４１の重なり部分の長さを調整して配置するルーフ板配置工程（第２部材配置工程）を行うと共に、固定台２２を段差１４以外の部分に配置する固定台配置工程を行う。なお、本実施形態においては、固定台配置工程及びルーフ板配置工程を行う順番は、いずれの工程が後先であってもよい。 On the other hand, in the present invention, as shown in FIGS. 4 and 5, each of the plurality of roof plates 41 has a first roof in a state where a part of the roof plate 41 is arranged in the accommodating recessed groove portion 30. In the inclined direction of the material 13, the roof plate side working length L2 is twice (integer times) the slate side working length L1 (first working length) of the overlapping portion of the adjacent roof plates 41. Arranged by adjusting the length.
When constructing the solar panel mounting structure 1 of the present invention, the roof plate side working length L2 and the slate side working length L1 of the plurality of roof plates 41 in the inclined direction of the first roofing material 13, respectively. The roof plate arranging step (second member arranging step) is performed by adjusting the length of the overlapping portion of the adjacent roof plates 41 so as to be an integral multiple of the above, and the fixing base 22 is placed on the portion other than the step 14. Perform the fixed table placement process for placement. In the present embodiment, any of the steps of the fixed base arranging step and the roof plate arranging step may be performed later.

ここで、図５に示すように、本実施形態においては、２つのルーフ板４１（第１ルーフ板４１ａ、第２ルーフ板４１ｂ）の重なり部分の長さを調整した場合において、第１ルーフ板４１ａの軒側端部接続板部４３の棟側の側面（側面）と、第２ルーフ板４１ｂの立ち上がり受け板部４４１の軒側の側面（側面）とは、対向して配置され、互いの間には、隙間Ｓが形成される。第１ルーフ板４１ａの軒側端部接続板部４３は、第１ルーフ板４１ａの軒側の端部において、ルーフ板本体４２から立ち下がるように形成される。第２ルーフ板４１ｂの立ち上がり受け板部４４１は、第２ルーフ板４１ｂの棟側に配置される棟側端部突出接続部４４の軒側の端部において、上面板部４４２から立ち下がるように形成される。 Here, as shown in FIG. 5, in the present embodiment, when the lengths of the overlapping portions of the two roof plates 41 (first roof plate 41a and second roof plate 41b) are adjusted, the first roof plate The side surface (side surface) of the eaves side end connection plate portion 43 of 41a on the ridge side and the side surface (side surface) of the rising receiving plate portion 441 of the second roof plate 41b on the eave side are arranged so as to face each other. A gap S is formed between them. The eaves-side end connection plate portion 43 of the first roof plate 41a is formed so as to stand down from the roof plate main body 42 at the eaves-side end portion of the first roof plate 41a. The rising receiving plate portion 441 of the second roof plate 41b descends from the upper surface plate portion 442 at the eaves-side end of the ridge-side end protruding connection portion 44 arranged on the ridge side of the second roof plate 41b. It is formed.

このように、図５に示すように、２つのルーフ板４１（第１ルーフ板４１ａ、第２ルーフ板４１ｂ）の間に隙間Ｓを形成することで、第２屋根材４のルーフ板４１のルーフ板側働き長さＬ２が、第１屋根材１３のスレート１３１の第１屋根材１３の２枚のスレート１３１の段差上面１４０の屋根の傾斜方向の働き総長さＬＴ（＝Ｌ１×２）となるように、隣接するルーフ板４１の重なり部分の長さを調整する。これにより、第２屋根材４のルーフ板４１のルーフ板側働き長さＬ２と、第１屋根材１３のスレート１３１の第１屋根材１３の２枚のスレート１３１の段差上面１４０の屋根の傾斜方向の働き総長さＬＴ（＝Ｌ１×２）とを、同じ長さになるように調整できる（Ｌ２＝ＬＴ）。 In this way, as shown in FIG. 5, by forming a gap S between the two roof plates 41 (first roof plate 41a, second roof plate 41b), the roof plate 41 of the second roof material 4 is formed. The working length L2 on the roof plate side is the total working length LT (= L1 × 2) of the slate 131 of the first roofing material 13 in the inclination direction of the step upper surface 140 of the two slate 131s of the first roofing material 13. The length of the overlapping portion of the adjacent roof plates 41 is adjusted so as to be. As a result, the roof plate side working length L2 of the roof plate 41 of the second roof material 4 and the inclination of the roof of the step upper surface 140 of the two slate 131 of the first roof material 13 of the slate 131 of the first roof material 13 The total working length LT (= L1 × 2) in the direction can be adjusted so as to have the same length (L2 = LT).

そのため、第２屋根材４のルーフ板４１のルーフ板側働き長さＬ２と第１屋根材１３の２枚のスレート１３１の働き総長さＬＴ（＝Ｌ１×２）とを、同じ長さ（Ｌ２＝ＬＴ）とすることにより、複数のルーフ板４１を傾斜方向に並べて配置した場合に、屋根の傾斜方向のいずれの位置においても、第１屋根材１３の段差１４と、第２屋根材４のルーフ板４１との位置関係は常に同じとなる。よって、屋根の傾斜方向において、複数の固定台２２と複数の段差１４との位置関係は、必ず同じ位置関係とすることができる。つまり、複数の固定台２２と複数の段差１４との位置関係は、第１屋根材１３の段差１４には、固定台２２が配置されない位置関係となる。 Therefore, the working length L2 of the roof plate 41 of the second roofing material 4 on the roof plate side and the total working length LT (= L1 × 2) of the two slate 131s of the first roofing material 13 are the same length (L2). = LT), when a plurality of roof plates 41 are arranged side by side in the inclined direction, the step 14 of the first roofing material 13 and the second roofing material 4 are arranged at any position in the inclined direction of the roof. The positional relationship with the roof plate 41 is always the same. Therefore, in the inclined direction of the roof, the positional relationship between the plurality of fixed bases 22 and the plurality of steps 14 can always be the same. That is, the positional relationship between the plurality of fixed bases 22 and the plurality of steps 14 is such that the fixed bases 22 are not arranged on the steps 14 of the first roofing material 13.

以上により、ルーフ板側働き長さＬ２は、スレート側働き長さＬ１（第１働き長さ）の２倍（整数倍）の長さとなるため、第１屋根材１３の段差１４に対するルーフ板４１の端部の位置を、段差１４を避けた位置に最初に設定すれば、複数のルーフ板４１を傾斜方向に並べて配置した場合に、複数の固定台２２の全ての設置位置を、複数の段差１４を避けた平面状の部分に配置することができる。これにより、ルーフ板４１の軒側端部接続板部４３が支持金具３の収容凹溝部３０に配置された状態で、複数のルーフ板４１を傾斜方向に並べて配置した場合に、屋根の傾斜方向におけるいずれの位置においても、複数の固定台２２を、第１屋根材１３の段差１４を跨がない位置に設置することができる。よって、既設の第１屋根材１３に固定台２２を安定して設置することができる。従って、太陽光発電パネル５３を安定して設置できる。 As described above, the roof plate side working length L2 is twice (integer times) the slate side working length L1 (first working length), so that the roof plate 41 with respect to the step 14 of the first roofing material 13 If the position of the end portion of the roof is first set to a position avoiding the step 14, when a plurality of roof plates 41 are arranged side by side in the inclined direction, all the installation positions of the plurality of fixing bases 22 can be set to a plurality of steps. It can be arranged in a flat portion avoiding 14. As a result, when a plurality of roof plates 41 are arranged side by side in the inclined direction in a state where the eaves side end connecting plate portion 43 of the roof plate 41 is arranged in the accommodating recessed groove portion 30 of the support metal fitting 3, the roof inclined direction. At any position in the above, a plurality of fixing bases 22 can be installed at positions that do not straddle the step 14 of the first roofing material 13. Therefore, the fixing base 22 can be stably installed on the existing first roofing material 13. Therefore, the photovoltaic power generation panel 53 can be stably installed.

Therefore, in order to ensure watertightness between the two roof plates 41 (first roof plate 41a, second roof plate 41b), a first roof plate 41a and the second roof plate 41b are separated from each other. The seal member 23 is arranged.

具体的には、第１シール部材２３は、隣接する２つのルーフ板４１（第１ルーフ板４１ａ、第２ルーフ板４１ｂ）の重なり部分において、第１ルーフ板４１ａのルーフ板本体４２の下面（下面）と、第２ルーフ板４１ｂの上面板部４４２の上面（上面）との間に配置される。第１シール部材２３は、図３に示すように、屋根の傾斜方向に交差する方向に延びており、ルーフ板４１の幅方向（屋根の傾斜方向に交差する方向）の全域に亘って配置されている。 Specifically, the first seal member 23 is the lower surface (the lower surface of the roof plate main body 42 of the first roof plate 41a) at the overlapping portion of the two adjacent roof plates 41 (the first roof plate 41a and the second roof plate 41b). It is arranged between the lower surface) and the upper surface (upper surface) of the upper surface plate portion 442 of the second roof plate 41b.

The seal member 24 is arranged.

第２シール部材２４は、隣接する２つのルーフ板４１（第１ルーフ板４１ａ、第２ルーフ板４１ｂ）の重なり部分において、第１ルーフ板４１ａの軒側端部接続板部４３の棟側の側面（側面）と、第２ルーフ板４１ｂの立ち上がり受け板部４４１の軒側の側面（側面）との間に配置される。 The second seal member 24 is located on the ridge side of the eaves side end connection plate portion 43 of the first roof plate 41a at the overlapping portion of the two adjacent roof plates 41 (first roof plate 41a, second roof plate 41b). It is arranged between the side surface (side surface) and the side surface (side surface) of the rising receiving plate portion 441 of the second roof plate 41b on the eave side.

詳細には、第２シール部材２４は、図７に示すように、ルーフ板４１の棟側壁部３４の棟側の側面（側面）の山谷形状の外面に沿って、ルーフ板４１の立ち上がり受け板部４４１の軒側の側面（側面）に貼り付けられている。第２シール部材２４は、図７に示すように、屋根の傾斜方向に交差する方向に延び、かつ、ルーフ板４１の立ち上がり受け板部４４１の軒側の側面において山谷形状に配置される。第２シール部材２４は、ルーフ板４１の幅方向（屋根の傾斜方向に交差する方向）の全域に亘って配置されている。 Specifically, as shown in FIG. 7, the second seal member 24 is a rising receiving plate of the roof plate 41 along the ridge-shaped outer surface of the side surface (side surface) of the ridge side wall portion 34 of the roof plate 41 on the ridge side. It is attached to the side surface (side surface) of the eaves side of the portion 441. As shown in FIG. 7, the second seal member 24 extends in a direction intersecting the inclination direction of the roof, and is arranged in a mountain valley shape on the side surface of the roof plate 41 on the eave side of the rising receiving plate portion 441. The second seal member 24 is arranged over the entire width direction of the roof plate 41 (direction intersecting the inclination direction of the roof).

第２実施形態によれば、以下の効果が奏される。
本実施形態では、第１ルーフ板４１ａと第２ルーフ板４１ｂとの間に、第２シール部材２４が配置される。詳細には、第２シール部材２４は、隣接する２つのルーフ板４１（第１ルーフ板４１ａ、第２ルーフ板４１ｂ）の重なり部分において、第１ルーフ板４１ａの軒側端部接続板部４３の棟側の側面（側面）と、第２ルーフ板４１ｂの立ち上がり受け板部４４１の軒側の側面（側面）との間に配置される。これにより、ルーフ板４１の働き長さを調整することで隣接するルーフ板４１の間に隙間Ｓが形成されても、隣接するルーフ板４１の間の水密性を確保できる。 According to the second embodiment, the following effects are achieved.
In the present embodiment, the second seal member 24 is arranged between the first roof plate 41a and the second roof plate 41b. Specifically, the second seal member 24 is the eaves-side end connection plate portion 43 of the first roof plate 41a at the overlapping portion of the two adjacent roof plates 41 (first roof plate 41a, second roof plate 41b). It is arranged between the side surface (side surface) on the ridge side of the building and the side surface (side surface) on the eave side of the rising receiving plate portion 441 of the second roof plate 41b. As a result, even if a gap S is formed between the adjacent roof plates 41 by adjusting the working length of the roof plate 41, the watertightness between the adjacent roof plates 41 can be ensured.

なお、本発明は上記実施形態に限定されるものではなく、本発明の目的を達成できる範囲での変形、改良等は本発明に含まれる。
例えば、前記実施形態では、ルーフ板側働き長さＬ２（第２働き長さ）が、第１屋根材１３のスレート１３１のスレート側働き長さＬ１（第１働き長さ）の２倍となるように、隣接するルーフ板４１との重なり部分の長さを調整して配置したが、これに限定されない。例えば、ルーフ板側働き長さＬ２（第２働き長さ）が、第１屋根材１３のスレート１３１のスレート側働き長さＬ１（第１働き長さ）の１倍となるように調整してもよいし、３倍以上となるように調整してもよい。 The present invention is not limited to the above embodiment, and modifications, improvements, and the like within the range in which the object of the present invention can be achieved are included in the present invention.
For example, in the above embodiment, the roof plate side working length L2 (second working length) is twice the slate side working length L1 (first working length) of the slate 131 of the first roofing material 13. As described above, the length of the overlapping portion with the adjacent roof plate 41 is adjusted and arranged, but the present invention is not limited to this. For example, the roof plate side working length L2 (second working length) is adjusted to be one times the slate side working length L1 (first working length) of the slate 131 of the first roofing material 13. It may be adjusted so that it may be tripled or more.

また、前記実施形態では、固定台２２を第１屋根材１３の傾斜方向に交差する方向に長く延びるように形成したが、これに限定されず、固定台２２を第１屋根材１３の傾斜方向に長く延びるように形成してもよい。 Further, in the above embodiment, the fixed base 22 is formed so as to extend long in the direction intersecting the inclined direction of the first roofing material 13, but the present invention is not limited to this, and the fixed base 22 is formed in the inclined direction of the first roofing material 13. It may be formed so as to extend long.

また、前記実施形態では、第１屋根材１３を、複数のスレート１３１で構成したが、これに限定されず、トタン屋根（板金屋根）や、アスファルトシングルの屋根などで構成してもよい。 Further, in the above-described embodiment, the first roofing material 13 is composed of a plurality of slate 131s, but the present invention is not limited to this, and a tin roof (sheet metal roof), an asphalt single roof, or the like may be used.
