PROBLEM TO BE SOLVED: To provide a roof structure with improved construction function, waterproof function, and other.SOLUTION: A male-female connection structure is formed on upper and lower ends, and a lower connection part and an upper connection part are formed on one edge and the other edge in a horizontal direction, respectively, of a roof material A. A back batten F comprises: a vertical planar waterproof surface F1; a convex positioning rib F2 formed near a center of the waterproof surface; a horizontal waterproof piece, which is formed by folding both ends of the waterproof surface back to outdoor side; an upper waterproof piece, which is formed by making a top edge of the waterproof surface incline and protrude toward outdoor side; a lower diagonal piece, which is formed by bending a lower end of the waterproof surface to indoor side; a locking piece, which is formed by bending a tip of the lower diagonal piece inward; and a packing material formed at a bottom end of the horizontal waterproof piece. The lower diagonal piece inclines and bends and is formed by notching right and left parts of the bent surface. The back batten is formed on a rear face of a vertical joint part between roof materials.SELECTED DRAWING: Figure 1 【課題】施工機能、防水機能、等を向上した屋根構造を提供する。【解決手段】上下端に雄雌連結構造を形成し、左右方向の一端縁には下連結部を形成し、他端縁には上連結部を形成した屋根材Ａと、垂直平面状の防水面Ｆ１と、防水面の中央付近に形成した凸条の位置決めリブＦ２と、防水面の両端部分を屋外側へ折り返した横防水片と、防水面の上端を屋外側へ傾斜して突出した上防水片と、防水面の下端を屋内側へ屈曲した下斜め片と、下斜め片の先端を内方に屈曲した係止片と、横防水片の下端に形成したパッキング材とから形成すると共に、下斜め片は傾斜して屈曲し、屈曲した面の左右部分を切り欠いて形成した敷目板Ｆとからなり、屋根材間の縦目地部裏面に敷目板を形成した。【選択図】図１
