PROBLEM TO BE SOLVED: To provide a waterproof roof tile that solves a problem with a roof tile having a drainer parallel to a flow direction, for preventing rainwater from seeping in through a gap between the roof tiles.SOLUTION: A plain roof tile has an integrally formed overlap part 2 on one side of a roof tile body 1 and an underlap part 3 formed on the other side. A plurality of guiding protrusions 10, 10a, ... is formed in parallel to a flow direction, the guiding protrusion being formed to be long on a rear surface of the overlap part 2, in a diagonal direction from an inner side toward outer and head sides. As a result, rainwater flowing down the rear surface of the overlap part 2 of the adjacent other roof tile is led to an outer edge part of the overlap part 2 through the guiding protrusions 10, 10a, .... Thus, the rainwater is prevented from reaching a part outside of a side edge part of the underlap part 3 underneath.SELECTED DRAWING: Figure 1
【課題】流れ方向に対し平行な水切りでは瓦間の隙間より侵入する雨水に対する雨仕舞いに問題が残る。【解決手段】瓦本体１の一側部位をオーバーラップ部２とし、他側方にアンダーラップ部３が一体形成された平板瓦であって、オーバーラップ部２の裏面に、内側より外方且つ頭側へ斜め方向に長く形成した複数の誘導突堤10、10a …を、流れ方向に並設することによって、隣接する他方の瓦のオーバーラップ部２の裏面を伝わる雨水を、誘導突堤10、10a …によりオーバーラップ部２の外側端縁部に誘導することで、下方のアンダーラップ部３の側端部より外側に相当する部分まで雨水を至らせない様にする。【選択図】図１
