  However, in order to refurbish the roof by partially replacing the roof material that is firmly fixed to the roof in this way, the roof material is firmly fixed, so it takes time for the renovation, or the renovation is a skill level of the installer Depending on the condition, it may become unstable or non-uniform.

  FIG. 8 is a cross-sectional view showing the installation structure of the existing roofing material 11. 9 and 10 show an example of a method for repairing the roof on which the roofing material 11 is installed, FIG. 9 is a perspective view, and FIG. 10 is a cross-sectional view. FIG. 9A shows the roof before renovation, and FIG. 9B shows the process of inserting a new roof material 11a after removing a part of the existing roof material 11b. FIG. 10 is an example of a conventional method, and shows a process of inserting and inserting a new roof material 11a after removing the existing roof material 11b.

  As shown in FIG. 8, on the roof, a plurality of roof materials 11 locks the tile bottom 12 to the tile rail 20, and the tile bottom of another roof material 11 adjacent to the tile head 13 in the direction parallel to the eaves. 12 is laid on the roof base 14 by a method of overlapping with the roof 12. In order to partially replace the plurality of roofing materials 11 installed in this manner, first, the existing roofing material 11b at the place to be replaced is indicated by, for example, the white arrow in FIG. 8 and the arrow in FIG. 9 (a). The roofing material 11b at the place is removed. At this time, the existing roofing material 11b to be removed may be destroyed. Next, as shown in FIG. 9B, the newly installed roofing material 11a is inserted along the arrow at the place where the existing roofing material 11b is removed. When inserting the new roofing material 11a, the tile head 13 of the existing roofing material 11b adjacent to the ridge side is lifted as shown by the white arrow in FIG. Then, the operator 25 guides the tile bottom 12 of the newly installed roof material 11a and inserts the roof material 11a into the space formed between the tile head 13 and the upper surface of the tile rail 20 by lifting the tile head 13. The tile bottom 12 is locked to the tile rail 20 and a new roof material 11a is inserted. In this way, it is possible to repair the roof by partially replacing the roof material 11.

There may be. In addition, when fixing by a fixing tool or a hook mechanism is performed not only at one place on one roof material 11 but also at a plurality of places, for example, the roof material 11b is applied to the tile bottom 12 and the side surface of the roof material 11. When the is fixed, the tile head 13 is hardly lifted. Then, it is difficult to make a large space between the tile head 13 and the upper surface of the tile rail 20, it becomes difficult to guide the tile bottom 12 of the newly installed roof material 11a to the upper surface of the tile rail 20, and it is difficult to insert the roof material 11a. Or it may be easy to hit the tiles 20. At this time, if an effort is made to insert the roofing material 11a with excessive force, the new roofing material 11a and the surrounding existing roofing material 11b may be damaged, and the aesthetics of the roofing material 11 may be impaired. is there. Moreover, the roofing material 11 other than the existing roofing material 11b removed at the time of repair may be broken, and construction time may be increased. In addition, the construction that replaces the existing existing roofing material 11b and the new roofing material 11a to be inserted without damaging the surroundings requires sufficient attention to the construction, increases the construction time, and greatly increases the proficiency of the installer. Depending on the situation, the construction may become unstable or the construction may not be uniform. In addition, when the newly installed roof material 11a cannot be inserted well, the newly installed or existing roof material 11 may be cut and processed to facilitate the insertion of the roof material 11a, which further increases the construction time. Thus, in order to refurbish the roof by partially replacing the roof material 11 that is strongly fixed, the construction time increases, or the construction becomes unstable or non-uniform depending greatly on the installer. To do. Patent Document 1 describes a method of removing a roof material for efficiently renovating the roof, but such a method does not improve the efficiency of the process of inserting and replacing the roof material.

The guiding portion 2 has an inclined surface 2 a that is fixed at a position where the upper end is substantially the same height as the upper surface of the roof tile 20 and is inclined downward at substantially the same height as the roof tile 20. As a result, when a part of the plurality of roofing materials 11 is replaced, the newly installed roofing material 11 a is easily inserted between the roof tile 13 and the top surface of the roof rail 20 by sliding on the roofing material replacement jig 1. The roofing material 11 can be easily replaced. Further, it is possible to prevent the newly installed roof material 11a from being caught on the tile rail 20 and difficult to get over the tile rail 20 at the time of insertion, and the replacement construction time can be shortened. In addition, the use of excessive force when inserting the newly installed roofing material 11a is suppressed, and the risk of damaging the roofing material 11 is greatly reduced. Damage can be suppressed. In addition, since the construction can be simplified, the construction of the repair of the roof can be made uniform and stabilized.

  In this embodiment, the roofing material replacement jig 1 includes a guide piece 5 that constitutes the guide portion 2 and a stack that extends from the upper end of the guide piece 5 in a direction toward the roof rail 20 substantially parallel to the top surface of the roof rail 20. A piece 3 and a fixed piece 4 extending from the lower end of the guide piece 5 along the roof base 14 are provided. The overlapping piece 3 is overlapped on the upper surface of the roof tile 20 when the roofing material changing jig 1 is attached. The fixed piece 4 is fixed to the roof base 14 when the roof material changing jig 1 is attached. The roofing material changing jig 1 includes the guide piece 5, the overlapping piece 3, and the fixing piece 4, so that the roofing material changing jig 1 can be easily fixed along the roof bar 20 and the roof base 14. It is possible to shorten the construction time for roof refurbishment and to perform renovation efficiently.

  Here, the guide piece 5, the overlapping piece 3, and the fixed piece 4 are configured by plate-shaped pieces, and the planar shape may be configured by a rectangular or trapezoidal plate. Thereby, each piece, such as the induction | guidance | derivation piece 5, the overlap piece 3, and the fixed piece 4, can be provided easily. Each piece is preferably formed of a rectangular plate in order to easily and efficiently manufacture the roofing material changing jig 1. At this time, when each piece such as the guide piece 5, the overlapping piece 3, and the fixed piece 4 is configured to have the same width (the length in the direction along the roof tile 20), the roof material replacement jig 1 is manufactured. In this case, it is preferable that the material can be manufactured more efficiently without waste of material. Moreover, it is preferable that the thickness of each piece is as thin as possible so that it is difficult to deform carelessly. Thereby, when inserting the newly installed roofing material 11a, it can suppress that the roofing material replacement jig | tool 1 protrudes and becomes difficult to insert, and it can repair efficiently. Moreover, it is preferable that the thickness of each piece is the same. Thereby, the roofing material changing jig 1 can be obtained easily.

  The roofing material replacement jig 1 of this embodiment may be made of a metal plate, may be made of aluminum, or may be made of resin. In this, it is preferable that it is comprised with the metal plate. Thereby, the overlapping piece 3 and the fixed piece 4 can be easily provided on the guide piece 5 by bending, and the roof material replacement jig 1 can be easily obtained. Moreover, by providing the roofing material changing jig 1 with a metal plate, the roofing material changing jig 1 that has high strength and is difficult to deform carelessly can be easily obtained. Moreover, the surface of the roofing material replacement jig 1 can be easily smoothed, and the newly installed roofing material 11a can be moved on the roofing material replacement tool 1 with little resistance.

  The guide part 2 has an inclined surface 2 a that guides the newly installed roof material 11 a to the upper surface of the roof bar 20 by sliding the surface of the guide part 2. In this embodiment, the guide part 2 is constituted by a guide piece 5, and the inclined surface 2 a is formed by the surface of the guide piece 5. The inclined surface 2a may be a rectangular or trapezoidal surface. In this, it is preferable that the inclined surface 2a is a rectangular surface. Thereby, the guidance | induction part 2 can be obtained easily. The inclined surface 2a is preferably a rectangular surface having a long side along the roof tile 20 when fixed along the roof tile 20. Thereby, the newly installed roof material 11a can be easily and stably passed over the guide portion 2, and the roof material 11 can be easily replaced to make the repair work of the roof uniform.

  The inclined surface 2 a provided in the guide portion 2 is a surface that is inclined downward from the position of the upper end of the roof tile 20 at substantially the same height as the roof rail 20. The inclined surface 2 a may be configured by the surface of the guide piece 5, and at this time, the guide piece 5 is formed to have a surface that is inclined downward at substantially the same height as the roof bar 20. The inclined surface 2 a may be a surface inclined upward with respect to the roof base 14. Here, the height is a distance in the vertical direction from the surface of the roof base 14. Therefore, the height of the tile rail 20 may be the height from the roof base 14 to the upper surface of the tile rail 20. The height substantially the same as the height of the roof bar 20 may be the same as the height of the roof bar 20, may be slightly lower, or may be slightly higher. The height of the guide part 2 is preferably such that when the guide part 2 is fixed, the upper end of the guide part 2 is positioned at substantially the same height as the top surface of the roof tile 20. As a result, it is possible to easily form a continuous slope from the roof base 14 to the upper surface of the tile pier 20 in the guide portion 2 and to easily guide the newly installed roofing material 11a to the upper surface of the tile pier 20. The construction of the roof can be simplified, and the construction of the roof renovation can be made uniform and stable.

  As shown in FIG. 2, the upper end of the guide portion 2 is fixed at a position that is substantially the same height as the upper surface of the roof tile 20. In this embodiment, the guide portion 2 is constituted by the guide piece 5, and the upper end of the guide piece 5 is fixed at a position substantially the same height as the upper surface of the roof tile 20. Here, the height position means a position indicated by a distance in a vertical direction from the surface of the roof base 14. The position substantially the same height as the top surface of the roof tile 20 may be the same height as the top surface of the roof tile 20, may be a slightly lower position, or may be a slightly higher position. It may be. In this embodiment, since the roofing material changing jig 1 is attached with the overlapping piece 3 being overlapped on the upper surface of the roof tile 20, the upper end of the guide piece 5 (guide portion 2) is slightly higher than the upper surface of the roof tile 20. Become position. The upper end of the guide part 2 is a height at which the newly installed roofing material 11a can be slid on the guide part 2 and guided to the upper surface of the roof tile 20 when the roof material changing jig 1 is fixed along the roof tile 20. It is preferable to be in the position. Thereby, when inserting the new roofing material 11a, it can suppress that the side surface of the tile bottom 12 is hooked on the roof tile 20, and the new roofing material 11a is connected to the roof head 13 and the roof rail 20. It can be easily inserted in between. Therefore, it is possible to shorten the replacement construction time and to make the repair construction uniform and stable. Further, when the upper end of the guide portion 2 is at a level substantially the same as the upper surface of the roof tile 20, the lower surface of the newly installed roofing material 11 a rides on the upper end of the guide portion 2, and the roof tile locking portion 15 moves from the roof tile 20. It can suppress that it remove | deviates and can fix the roofing material 11 to a roof stably. In this way, the upper end of the guide portion 2 is fixed at a position that is substantially the same height as the top surface of the roof tile 20, so that the newly installed roofing material 11a can be easily replaced, and the replacement construction time can be shortened. It can be modified to a roof with high wind resistance and earthquake resistance. In addition, when the upper surface of the tile rail 20 is not provided in parallel with the roof base 14, for example, when the upper surface of the tile rail 20 is an inclined surface, the position of the height of the upper end of the guide portion 2 is the tile rail. It may be at a position substantially the same as the height of the 20 eaves side ends.

  The slope angle θ formed by the inclined surface 2a of the guide portion 2 and the roof base 14 is preferably in the range of 10 to 45 °. When the slope angle θ is in this range, the newly installed roofing material 11a can be easily lifted on the inclined surface 2a of the guide portion 2 and can be easily inserted, and the appearance of the roofing material 11 is prevented from being damaged. It is possible to make the roof renovation work uniform and stable. Moreover, the roof material 11a is strongly strengthened by suppressing the tile roof engaging leg 15b of the replaced new roof material 11a and the inclined surface 2a of the guide portion 2 from contacting and pressing the new roof material 11a upward. It can be fixed and can improve the wind resistance and earthquake resistance of the roof after renovation. In addition, it is easier to insert the newly installed roofing material 11a when the inclined surface 2a is inclined more gently. Therefore, the slope angle θ may be 30 ° or less.

  The length of the inclined surface 2a of the guide portion 2 in the eaves-ridge direction is preferably 1.2 to 10 times the height of the roof rail 20, and more preferably 1.4 to 6 times. Thereby, the newly-installed roofing material 11a can be smoothly slid on the guide piece 5, and the construction can be simplified and the construction time can be shortened. The length of the inclined surface 2a is the shortest linear distance connecting the upper end and the lower end of the inclined surface 2a on the inclined surface 2a.

  The inclined surface 2a of the guide portion 2 may be configured with a single surface as in this embodiment, or a plurality of surfaces may be formed continuously. For example, the inclined surface 2a may be composed of two inclined surfaces. In addition, when the inclined surface 2a is composed of a plurality of surfaces, the angle formed by the flat surface formed by connecting the upper end and the lower end of the inclined surface 2a and the roof base 14 may be the slope angle θ.

  Moreover, although the inclined surface 2a may be comprised by the curved surface, it is preferable to comprise by a plane like this form. By forming the inclined surface 2a as a flat surface, the newly installed roofing material 11a can be easily guided above the roof tile 20, and the roofing material 11 can be easily replaced. Moreover, when the inclined surface 2a is a plane, the roofing material replacement jig 1 can be obtained easily. In addition, when the inclined surface 2a is configured by a plurality of surfaces, it may be configured by a plurality of planes, may be configured by a plurality of curved surfaces, or may be configured by a combination of a plane and a curved surface. .

  The guide width W, which is the length of the side along the roof bar 20 of the guide portion 2, can be set as appropriate according to the roof material 11 to be used, but is preferably 30 mm or more, and the eaves of the roof material 11 It is preferable that the length is not more than the length in the parallel direction. As a result, the roofing material changing jig 1 can be easily installed on the part where the existing roofing material 11b is removed, and the newly installed roofing material 11a can be easily placed on the guide portion 2 and moved. Can be shortened and the construction can be made uniform and stabilized. Further, when a plurality of roofing material changing jigs 1 are installed in a place where one roofing material 11 is removed, the guide width W is a length that can be arranged without overlapping the roofing material changing jigs 1 along the roof tiles 20. The following is preferable. For example, when two roofing material changing jigs 1 are installed in a place where one roofing material 11b is removed, the guide width W is ½ or less of the length in the direction parallel to the eaves of the roofing material 11. It is preferable that when three roofing material changing jigs 1 are used, the length is preferably 1/3 or less of the length in the direction parallel to the eaves of the roofing material 11. In addition, if the guide width W is within this range, a larger one is preferable because repairability is improved. For example, the guide width W may be 1/20 or more of the length in the direction parallel to the eaves of the roofing material 11, or may be 1/5 or more.

  The fixing piece 4 is a piece for fixing the roofing material changing jig 1 to the roof base 14. In this embodiment, the fixed piece 4 is formed to extend from the lower end of the guide piece 2 in the direction opposite to the direction in which the overlap piece 3 is extended along the roof base 14 (the direction toward the eaves). Thus, it is preferable that the fixed piece 4 is extended toward the direction opposite to the direction where the overlap piece 3 was extended. Thereby, the fixed piece 4 can be easily fixed to the roof base 14, and the roofing material replacement jig 1 can be easily fixed to the roof base 14 so that the repair can be performed efficiently.

  The fixing piece 4 is preferably provided with a fixing hole 6. Accordingly, the roof material changing jig 1 can be easily and strongly fixed to the roof base 14 by hitting a fixing tool 30 such as a nail or a screw into the fixing hole 6. Even when the fixing hole 6 is not provided in the fixing piece 4 in advance, the fixing piece 4 may be fixed by providing the fixing hole 6 with the fixing tool 30 at the same time when the fixing tool 30 is attached. Alternatively, the fixing piece 4 may be fixed by providing an adhesive material such as an adhesive or a double-sided tape on the lower surface of the fixing piece 4. Of course, the fixing piece 4 may be fixed to the roof base 14 by providing an adhesive, and the fixing piece 4 may be further fixed by the fixing tool 30. In this embodiment, one fixing hole 6 is provided in the fixing piece 4, but a plurality of fixing holes 6 may be provided in one fixing piece 4.

  The length of the fixing piece 4 in the extending direction (length in the eaves building direction) may be appropriately set to a length at which the roofing material changing jig 1 can be fixed. In this embodiment, it may be an appropriate length that can be fixed by the fixing tool 30, and can be, for example, about ¼ to 5 times the length of the overlapping piece 3 in the extending direction. Thereby, while suppressing that the fixed piece 4 protrudes in the large range on the roof base 14, the fixed piece 4 can be firmly fixed to the roof base 14, and the roof material 11 can be replaced easily. Further, the length of the fixed piece 4 may be one time or less than the length of the overlapping piece 3 in the extending direction. Thereby, it can suppress more that the fixed piece 4 protrudes in the wide range on the roof base | substrate 14, makes it easy to replace the roofing material 11, and can improve the efficiency of repair.

  Here, although the form shown by FIGS. 1-3 was demonstrated as an example of the roofing material replacement jig | tool 1, the form of the roofing material replacement jig | tool 1 in which the guidance part 2 is comprised with the guidance piece 5 is limited to this. It is not something. The roofing material changing jig 1 is fixed such that the upper end of the guide piece 5 is fixed at a position substantially the same height as the upper surface of the roof tile 20, and the guide piece 5 is inclined at the same height as that of the roof tile 20. An appropriate structure having the surface 2a may be used.

  For example, the roof crossing jig 1 does not need to be provided with the tile crosspiece locking piece 7. Accordingly, when the overlapping piece 3 is placed on the top surface of the roof tile 20, the overlapping piece 3 can be easily inserted between the roof tile 20 and the tile head 13. It can be installed easily. In this embodiment, the length of the overlapping piece 3 in the extending direction may be shorter than the length of the roof tile 20 in the eaves-ridge direction. As a result, the roofing material changing jig 1 can be used for the tile rails 20 having various widths (thicknesses), and the overlapping pieces 3 can be easily overlapped and followed by the tile rails 20 so that the work efficiency of the repair is improved. Can be increased.

  The roofing material changing jig 1 does not have to be provided with the fixed piece 4. At this time, the roofing material changing jig 1 may be fixed to the roof tile 20 with the overlapping piece 3 or with the overlapping piece 3 and the roof tile locking piece 7. The fixed piece 4 may extend from the lower end of the guide piece 2 along the roof base 14 in the same direction as the overlap piece 3. In this case, it is possible to suppress the fixed piece 4 from protruding on the roof base 14, and to prevent the fixed piece 4 from being caught when the new roof material 11 a is inserted, and to easily insert the roof material 11 a. be able to. When the fixed piece 4 extends in the same direction as the stacked piece 3, the length of the fixed piece 4 in the extending direction is the side surface of the roof tile 20 along which the fixed piece 4 extends along the upper end of the guide piece 5. It is preferable that the length is in a range that does not contact the surface. Thereby, the roofing material replacement jig 1 can be easily and strongly fixed to the roof base 14, and the time required for repairing can be shortened.

  Next, a roof repair method for replacing a part of the plurality of roof materials 11 using the roof material replacement jig 1 will be described.

  FIG. 9 is a perspective view illustrating an example of a method for changing a part of the plurality of roofing materials 11. In FIG. 9, the roofing material 11 having the form shown in FIG. 7A is used, and the roofing material adjacent to the existing roofing material 11 b as shown in the erected structure in FIGS. 7B and 8. 11b and the tile rail 20 are engaged and fixed at the side end and the tile bottom 12. FIG. 9A shows a state before renovation, and FIG. 9B shows a process for inserting a newly installed roof material 11a.

  Fig.1 (a) is sectional drawing of the insertion process of the newly installed roofing material 11a, and FIG.1 (b) is sectional drawing which shows an example after inserting and repairing.

  When replacing a part of the plurality of roofing materials 11, after removing the existing roofing material 11b, the roofing material replacement jig 1 is fixed along the roof tile 20, and the newly installed roofing material 11a is replaced with a roofing material. It is preferable that the tool 1 is slid and inserted between the tile head 13 of the existing roof material 11b adjacent to the ridge side and the tile rail 20. Thereby, the newly installed roofing material 11a can be inserted between the tile head 13 and the tile rail 20 by sliding on the roofing material replacement jig 1, and can be easily replaced. Therefore, the construction time for replacement can be shortened, the risk of damaging the roofing material 11 can be greatly reduced, and the roofing material 11 can be prevented from being damaged when inserted, and the aesthetics can be prevented. Renovation work can be made uniform and stable.

  In repairing a roof on which a plurality of roofing materials 11 are installed, first, the existing roofing material 11b at a place to be replaced is removed. For example, in FIG. 9A, it is assumed that the existing roof material 11b indicated by the arrow is removed. An appropriate method may be used to remove the existing roofing material 11b, but it is easy and preferable to remove it. Next, as shown in FIG. 1A and FIG. 2, the roofing material replacement jig 1 is fixed along the roof tile 20 to the roof base 14 where the existing roofing material 11 b is removed.

  The roof material replacement jig 1 can be fixed by inserting the roof material replacement jig 1 between the tile head 13 of the existing roof material 11b adjacent to the building side and the tile rail 20. At this time, for example, the overlap piece 3 and the tile-bar locking piece 7 are inserted into the space between the tile head 13 and the upper surface of the tile frame 20, and the tile frame 20 is locked by the tile-frame locking piece 7, The overlapping piece 3 is overlapped on the upper surface of the tile rail 20, and the roof material changing jig 1 is placed along the tile rail 20. Further, the tile head 13 of the existing roof material 11b may be lifted upward so that the roof material replacement jig 1 can be easily inserted. In addition, when the roofing material changing jig 1 is not provided with the tile crossing locking piece 7, the overlapping piece 3 may be simply stacked on the top surface of the tile crossing 20.

  Then, by fixing the fixing piece 4 to the roof base 14, the roofing material replacement jig 1 can be fixed along the roof tile 20. A method of fixing the fixing piece 4 to the roof base 14 is preferably a method of fixing by fixing a fixing tool 30 such as a nail or a screw into the fixing hole 6 of the fixing piece 4. Thereby, the roofing material replacement jig 1 can be easily and firmly fixed to the roof base 14, the roofing material replacement jig 1 is difficult to be displaced, the replacement of the roofing material 11 is facilitated, and the construction efficiency is improved.

Moreover, the method of fixing the roofing material changing jig 1 is not using the fixing tool 30 or in addition to the fixing tool 30, and by providing an adhesive to the overlapping piece 3 and the tile-bar locking piece 7. A method of fixing to the roof base 14 by providing an adhesive on the fixing piece 4 may be used.

  One or more roofing material changing jigs 1 can be installed in accordance with the shape of the roofing material 11 at a place where one roofing material 11 is removed. For example, as shown in FIG. 7 (b), when the roof tiles 12 of the roofing material 11 are provided with the roof tile locking portions 15 at two places along the longitudinal direction of the roof tile 20, In order to facilitate the insertion of the roofing material 11a, it is preferable to install two roofing material changing jigs 1 in accordance with the position of the roof tile locking part 15. The guide width W at this time is set to be ½ or less of the longitudinal length of the roof tiles 20 in the roof material 11 so that the roof material replacement jig 1 can be arranged without being overlapped along the roof tiles 20. It is preferable.

  After fixing the roofing material changing jig 1 along the roof tile 20, as shown in FIG. 9 (b), the new roofing material 11a is attached to the tile bottom 12 at the portion where the existing roofing material 11b is removed. Inserted between the tile head 13 of the existing roofing material 11b on the eaves side and the upper surface of the tile rail 20 close to the side. The newly installed roof material 11a has the same shape as the existing roof material 11b. When the new roof material 11a is inserted, the lower end of the tile bottom 12 of the new roof material 11a is placed on the guide portion 2 as shown in FIG. At this time, the leading end of the roof tile locking leg 15a and the guide portion 2 come into contact with each other. Then, as shown by the arrows in FIG. 1 (a), the tile bottom 12 of the newly installed roofing material 11a is slid to the ridge side on the guide portion 2 to be guided above the tile rail 20, and the tile head 13 and the tile Insert between the upper surface of the crosspiece 20. At this time, in order to facilitate the insertion of the new roofing material 11a, it is preferable to lift the roof tile 13 of the existing roofing material 11b on the ridge side as indicated by the white arrow in FIG. When using the roofing material changing jig 1, the new roofing material 11a is slid on the guide portion 2 and moved to the position where the roof tile 12 of the new roofing material 11a is inserted. Therefore, the amount of lifting the tile head 13 can be reduced.

  In this way, by using the roofing material changing jig 1, the newly installed roofing material 11a can be easily inserted between the roof bar 20 and the roof head 13 by sliding on the guide portion 2, and therefore, Construction time can be shortened. Moreover, since the newly-installed roofing material 11a can be easily inserted, it is not necessary to require a special skill and experience from the installer, and the construction can be made uniform and stable. Further, it is possible to prevent the roof head 11b of the existing roofing material 11b from being lifted by excessive force or the new roofing material 11a from being excessively inserted during insertion. Can be suppressed. In addition, since the new roofing material 11a can be easily inserted, the number of times and the degree of cutting of the roofing material 11 to make it easier to insert the new roofing material 11a can be reduced or processed. Can be eliminated. Moreover, even when the existing roof material 11b is fixed at the tile bottom 12 or the side end portion and the tile head 13 is difficult to lift as in this embodiment, the roof material changing jig 1 is inserted in the guide portion 2 in the insertion direction. Therefore, the roof material 11 can be easily replaced. Further, in this embodiment, since the overlapping piece 3 is arranged so as to cover the upper surface of the roof tile 20, the newly installed roofing material 11 a can be smoothly inserted over the roof tile 20.

  In this embodiment, a superposed upper portion 21 and a superposed lower portion 22 are provided at the side end of the roofing material 11. Therefore, when the new roofing material 11a is inserted, the superposed lower portion 22 of the new roofing material 11a runs along the superposed upper portion 21 of one existing roofing material 11b adjacent in the direction parallel to the longitudinal direction of the roof tile 20. Preferably. At the same time, it is preferable that the superposed upper portion 21 of the newly installed roofing material 11a is placed on the superposed lower portion 22 of the other existing roofing material 11b adjacent in the direction parallel to the longitudinal direction of the roof tile 20. Thereby, when inserting the new roofing material 11a by sliding on the guidance | induction part 2, a side edge part can be piled up. Thus, by using the roofing material replacement jig 1, even if the roofing material 11 has a structure in which the adjacent roofing material 11 is engaged with the side edges, the roofing material replacement jig is used. Since it slides on 1 and is inserted, a side edge part can be engaged smoothly. Therefore, by using the roofing material changing jig 1, the roofing material 11 of the roof in which one roofing material 11 is fixed at a plurality of locations and installed on the roof base 14 to improve wind resistance and earthquake resistance. Can be easily replaced.

  Then, the tile roof locking portion 15 of the newly installed roof material 11a inserted in this manner is hooked on the roof tile 20 and locked. At this time, since the roofing material replacement jig 1 is installed between the newly installed roofing material 11 a and the tile rail 20, the tile rail locking portion 15 is connected to the tile rail 20 via the roofing material replacement jig 1. You may make it engage with. When the new roofing material 11a is installed, the tile rail engaging leg 15b and the guide portion 2 may be in contact with each other or may not be in contact with each other.
