In FIG. 1 (d), the roof material K is shown by a dotted line.

Next, the structure for repairing the wall joint portion of the new tile roof according to the present invention will be briefly described through construction examples. That is, as shown in FIG. 1, an asphalt roofing A is applied over the entire surface between an existing roof α and an existing wall β, which are made of a base plate α ₁ , an asphalt roofing α ₂ and a new tile roof material α ₃ . Next, after constructing the receiving tree B, the discarding plate C is continuously constructed. After that, the backup material J and the roof material K are constructed as shown in FIG. 12, and the ends are constructed by inserting the roof material K as shown in FIG. 10 into the running water groove 6 of the discard plate C. Next, the wall drainer E is formed as shown in FIG. Next, the waterproof tape F is continuously formed between the fixing surface 7 of the wall drainer E and the existing wall β. Next, the receiving tree G is formed on the fixing surface 7 of the wall drainer E by the fixing tool γ. After that, the engaging groove 17 of the wall presser H is engaged with the tongue piece 4 of the discard plate C and the tongue piece 9 of the drainer E for the wall, and the upper surface 13 of the upper end is fixed to the receiving tree G by the fixing tool γ. , Fix the wall holder H. Next, stepped doors D are inserted step by step into a triangular space between the surface of the roofing material K and the discard plate C, and finally, the ceiling I is continuously formed between the existing wall β and the upper surface 13. It is formed and the construction is completed. In addition, a sealing I is formed in a necessary portion to ensure waterproofness.

Further, the roof members K are connected to each other in the left-right direction through the joint member L as shown in FIG. That is,
The connecting piece 25 of the one roof material K and the one locking tongue piece 34 of the joint material L are locked in advance so as to be a combination, and are arranged on the existing roof α. Next, the other roofing material K is slid so that the connecting piece 25 and the other locking tongue piece 34 of the joint material L are assembled to complete the connection. At this time, the tip of the fixed piece 21 of the roof material K is inserted into the rain return part 29 of the joint material L and abuts on it, and the recess 28 of the joint material L causes the back surface 22 of the roof material K and the stepped surface 23. The roof member K which is fitted and inserted in the substantially U-shaped fitting groove 24a formed by the plug-in engagement piece 24 and the tongue piece 28a is located in the lower stage.
It will be in the state fitted in the engaging groove 19 of.

In the left and right connecting portions thus formed, rainwater that tries to enter the inside is subjected to primary waterproofing by the fitting body L ₂ , secondary waterproofing by the locking portion 30, and the extension portion 31,
The tongue piece 32 has a triple waterproof structure of tertiary waterproofing, which greatly improves waterproofness. Further, since the joint material L is fixed by the left and right roof materials K, the workability is good, and the joint material L itself does not move. The new roof is formed by performing the steps one by one from the eaves to the ridge in the procedure described above.
