The eaves cross member 3 is also called a fascia board. Examples of the building 1 include a detached house, an apartment building, and a public facility. The building 1 in the first embodiment is a detached house.
[0021] <Eaves structure> As shown in FIG. 2, in the eaves structure 2, an eaves gutter 6 is provided on an end surface 4C of the sheathing board 4 so as to cover the end surface 4C. The eaves gutter 6 has a lower board portion 6A and an attachment portion 6B. The lower board portion 6A is provided on the lower surface 4A of the sheathing board 4 and extends horizontally along the eaves edge. In addition, an eaves cross member 3 is provided on the lower surface 4A via the lower board portion 6A. The eaves cross member 3 is joined to the lower board portion 6A and extends along the eaves edge (see FIG. 1). The attachment portion 6B is provided on the upper surface 4B of the sheathing board 4 and extends horizontally along the eaves edge.
[0022] The eaves cover 10 is provided at the eaves so as to cover the eaves gutter 6. The eaves cover 10 includes a cover body 12 that covers at least a part of the eaves gutter 6, and an insert portion 11 that is provided on the cover body 12 and disposed between the sheathing board 4 and the roofing material 5. The insert portion 11 extends along the sheathing board 4 and is disposed so as to overlap the mounting portion 6B. The waterproof sheet 7 is laid between the sheathing board 4 and the roofing material 5. In this embodiment, the waterproof sheet 7 is laid so as to overlap the insert portion 11. The roofing material 5 is provided on the sheathing board 4 via the mounting portion 6B, the insert portion 11, and the waterproof sheet 7. Examples of the roofing material 5 include roof tiles, slate, and metal roofing materials. The roofing material 5 in this embodiment is slate 5A.
[0023] The roofing material 5 may be a wavy tile. When the roofing material 5 is a wavy tile, the fixing members 20 (see below) may be attached to the crests of the wavy tiles or to the valleys of the wavy tiles. Preferably, the fixing members 20 are attached to the valleys of the wavy tiles.
[0024] The insertion portion 11 of the eaves cover 10 is fixed to the sheathing board 4 by a fixing member 20. Examples of the fixing member 20 include a screw and a bolt.

The connecting portion 15 is connected to the upper end 14A of the back cover portion 14. The connecting portion 15 extends along the lower plate portion 6A (see FIG. 2). The inner end 15A of the connecting portion 15 contacts the eaves end cross member 3 (see FIG. 2). The fixing portion 13 extends downward from the inner end 15A of the connecting portion 15. The fixing portion 13 is configured to fit along the eaves-end horizontal member 3 (see FIG. 2).
[0029] <How to repair the roof> A roof renovation method for renovating a roof 100 with an eaves cover 10 will be described with reference to Figs. 4 to 7. The roof renovation method is a renovation method that does not depend on whether the roof material 5 of the roof 100 is to be renovated or not. For example, the roof renovation method of this embodiment can be performed in a renovation including overlay or reroofing, and can be performed without renovating the slates 5A of the roof 100. In this embodiment, the roof renovation method includes an insertion step of inserting the insertion part 11 of the eaves cover 10 between the sheathing board 4 and the slates 5A and covering the eaves gutter 6 with the cover body 12, and a fixing step of fixing the insertion part 11 to the sheathing board 4 with screws 20A. First, the existing eaves structure 2 will be described with reference to Fig. 4.
[0030] As shown in Fig. 4, the eaves structure 2 of this embodiment includes an eaves cross member 3, a sheathing board 4, a slate 5A, an eaves gutter 6, a waterproof sheet 7, and a roof fixing member 8. In this embodiment, the roof fixing member 8 is a screw 8A. The roof fixing member 8 may be a bolt. First, the screw 8A is removed to allow the slate 5A to move. Then, the insertion process is performed.
[0031] Next, as shown in Fig. 5, in the insertion process, a gap 40 is provided between the sheathing board 4 and the slate 5A using a half-opening tool 30 that opens the gap between the sheathing board 4 and the slate 5A. In this embodiment, the half-opening tool 30 is a crowbar 30A. When providing the gap 40 between the slate 5A and the sheathing board 4 with the crowbar 30A, the tip of the crowbar 30A is inserted between the waterproof sheet 7 and the eaves edge gutters 6, and the slate 5A is lifted up together with the waterproof sheet 7.
[0032] Then, as shown in FIG. 6, in the insertion step, the insertion portion 11 is inserted into the gap 40 so that the insertion portion 11 is disposed between the waterproof sheet 7 and the sheathing board 4. Specifically, first, the opening 16 of the eaves cover 10 is opened, and the eaves gutter 6 is passed through the opening 16. After that, the opening 16 is returned to its original state in a state in which the back surface 6C of the eaves gutter 6 is covered by the back cover portion 14 and the front surface 6D of the eaves gutter 6 is covered by the cover body 12. Next, the fixing portion 13 is brought into close contact with the eaves cross member 3, and the connecting portion 15 is disposed along the lower surface 4A of the sheathing board 4. Then, the slate 5A is returned to its original position so that the end 7A of the waterproof sheet 7 is sandwiched between the upper surface 11A of the insertion portion 11 and the lower surface 5B of the slate 5A.
[0033] 7, in the fixing step, the screws 20A are driven so as to penetrate the slates 5A and the insertion portions 11 and further into the sheathing board 4. This fixes the eaves cover 10 to the eaves.
[0034] Furthermore, in this embodiment, screws 21A are driven into the eaves-end horizontal member 3 so as to penetrate the fixing portion 13. This fixes the fixing portion 13 to the eaves-end horizontal member 3. Furthermore, in the roof renovation method, when the screws 8A are removed, the screw holes formed in the roof 100 may be filled with a sealant or the like to close them. In this embodiment, illustration of the screw holes is omitted.
[0035] The operation of this embodiment will now be described. The cover body 12 of the eaves cover 10 covers at least a part of the eaves drip edge 6. An insertion portion 11 is provided so as to protrude from an upper end 12A of the cover body 12. The insertion portion 11 is disposed between the sheathing board 4 and the roof material 5.
[0036] In conventional roof repair methods, the roof material is repaired along with the eaves. With conventional roof repair methods, it is difficult to repair only the eaves. In this regard, according to this embodiment, as described above, the cover body 12 is provided with an insertion portion 11 that protrudes from the upper end 12A of the cover body 12. The insertion portion 11 is disposed between the sheathing board 4 and the roof material 5, and the cover body 12 covers at least a portion of the eaves gutter 6. For this reason, the eaves can be repaired without the need for new roof material.
[0037] The effects of this embodiment will be described. (1) The eaves cover 10 covers the eaves gutter 6. The eaves cover 10 comprises a cover body 12 that covers at least a portion of the eaves gutter 6, and an insertion portion 11 that is provided on the cover body 12 and disposed between the sheathing board 4 and the roof material 5 of the building 1. With this configuration, the insertion portion 11 can be disposed between the sheathing board 4 and the roof material 5. Therefore, the eaves can be renovated without the need for new roof material.
[0038] (2) The eaves cover 10 further includes a fixing portion 13 fixed to the eaves cross member 3, a back cover portion 14 covering the back surface 6C of the eaves gutter 6, and a connecting portion 15 provided along the underside 4A of the sheathing board 4. According to this configuration, the connecting portion 15 of the eaves cover 10 is provided along the underside 4A of the sheathing board 4 of the roof 100, thereby improving the appearance of the eaves after renovation.
[0039] (3) In the eaves cover 10, the insertion portion 11 is provided so as to protrude from the upper end 12A of the cover body 12. The rear cover portion 14 extends from the lower end 12B of the cover body 12. The connecting portion 15 is connected to the upper end 14A of the rear cover portion 14. The fixing portion 13 extends downward from the inner end 15A of the connecting portion 15. With this configuration, the insertion portion 11, the cover body 12, the rear cover portion 14, the connecting portion 15, and the fixing portion 13 are configured as a continuous body with no branching portions. This improves the appearance of the eaves after renovation.
[0040] (4) The eaves structure 2 includes a sheathing board 4, a roofing material 5, an eaves gutter 6 provided at the eaves, and an eaves cover 10 described in any one of (1) to (3) above. According to this configuration, the eaves cover 10 can cover the eaves gutter 6 by disposing the insertion portion 11 of the eaves cover 10 between the sheathing board 4 and the roofing material 5.
[0041] (5) In the eaves structure 2, the insertion portion 11 of the eaves cover 10 is fixed to the sheathing board 4 by the fixing member 20. This configuration can improve the work efficiency of repairing the eaves of the eaves cover 10 at the eaves. In addition, the eaves cover 10 can be easily fixed to the sheathing board 4.
[0042] (6) The eaves structure 2 further includes a waterproof sheet 7 laid between the sheathing board 4 and the roofing material 5. The waterproof sheet 7 is laid so as to overlap the insertion portion 11. With this configuration, the waterproof sheet 7 overlaps the insertion portion 11, making it difficult for rainwater and the like to infiltrate into the roof 100. This makes it possible to suppress water intrusion at the eaves.
[0043] (7) In the roof renovation method, a roof 100 comprises a sheathing board 4, a roofing material 5, and an eaves gutter 6. An eaves cover 10 comprises a cover body 12 that covers at least a portion of the eaves gutter 6, and an insertion portion 11 that is provided on the cover body 12 and disposed between the sheathing board 4 and the roofing material 5. The roof renovation method includes an insertion step of inserting the insertion portion 11 of the eaves cover 10 between the sheathing board 4 and the roofing material 5, and covering the eaves gutter 6 with the cover body 12. According to this configuration, the eaves gutter 6 can be covered by inserting the insertion portion 11 of the eaves cover 10 between the sheathing board 4 and the roofing material 5.
[0044] (8) The roof renovation method further includes a fixing step of fixing the insertion portion 11 to the sheathing board 4 with the fixing member 20. In the fixing step, the fixing member 20 is driven so as to penetrate the roof material 5 and the insertion portion 11, and then into the sheathing board 4. According to this configuration, the fixing member 20 connects the roof material 5, the insertion portion 11, and the sheathing board 4 to one another. This makes it possible to improve the fixed state of the eaves cover 10 at the eaves.
[0045] (9) In the roof renovation method, the roof 100 further comprises a waterproof sheet 7 laid between the sheathing boards 4 and the roofing material 5. In the insertion step, the insertion portion 11 is inserted between the waterproof sheet 7 and the sheathing boards 4. With this configuration, the waterproof sheet 7 is layered on top of the insertion portion 11, making it difficult for rainwater and the like to penetrate into the interior of the roof 100. This makes it possible to renovate the eaves to prevent water from entering.
[0046] (10) In the roof repair method described in any one of (7) to (9) above, in the insertion step, a gap 40 is provided between the sheathing board 4 and the roofing material 5 using the half-opening tool 30. Then, the insertion portion 11 is inserted into the gap 40. With this configuration, since a gap 40 is provided between the sheathing board 4 and the roofing material 5, it becomes easier to insert the insertion portion 11 between the sheathing board 4 and the roofing material 5. This improves the work efficiency of repairing the eaves.
[0047] <Second embodiment> The eaves structure 2 of the building 1 of the second embodiment will be described with reference to Fig. 8. In this embodiment, the configurations common to the first embodiment are given the same reference numerals as the configurations of the first embodiment, and the description of the overlapping configurations will be omitted.
[0048] 8, the eaves structure 2 of the building 1 of this embodiment includes a sealant 50. The sealant 50 is provided so as to seal a boundary 60 between the cover body 12 and the lower surface 5B of the slate 5A.
[0049] According to the configuration of this embodiment, the boundary 60 between the cover body 12 and the lower surface 5B of the slate 5A is sealed by the sealing material 50. This makes it difficult for rainwater and the like to infiltrate into the interior of the roof 100. This makes it possible to suppress the intrusion of water at the eaves.
[0050] <Modification> The above-mentioned embodiments are examples of possible forms of the eaves cover 10, the eaves structure 2 of the building 1, and the roof renovation method, and are not intended to limit the forms. The eaves cover 10, the eaves structure 2 of the building 1, and the roof renovation method may take forms different from those exemplified in the above-mentioned embodiments. One example is a form in which part of the configuration of the embodiment is replaced, changed, or omitted, or a form in which a new configuration is added to the embodiment. An example of a modified example of the embodiment is shown below.
[0051] (1) The eaves cover 10 may be formed by combining multiple metal plates or multiple resins. For example, the insertion portion 11 may be formed of a metal plate, and the cover body 12, the fixing portion 13, the back cover portion 14, and the connecting portion 15 may be formed of resin. In this case, the upper end 12A of the cover body 12 and the insertion portion 11 may be integrally molded.
[0052] According to this configuration, the material for forming the eaves cover 10 can be selected as necessary. This makes it easier to improve the water resistance and durability of the eaves cover 10.
[0053] (2) The back cover portion 14 of the eaves cover 10 may have drainage holes. With this configuration, if rainwater infiltrates inside the roof 100, the rainwater is drained through the drainage holes. This makes it possible to suppress corrosion of the eaves gutter 6 inside the eaves cover 10 and deterioration of the eaves cover 10 due to this corrosion.
[0054] (3) The eaves structure 2 of the building 1 may include an internal sealant between the insertion portion 11 of the eaves cover 10 and the waterproof sheet 7. The internal sealant is provided so as to tightly contact the insertion portion 11 and the waterproof sheet 7. With this configuration, the internal sealant is provided at the boundary between the insertion portion 11 and the waterproof sheet 7, making it difficult for rainwater and the like to penetrate into the interior of the roof 100.
