    Abstract: The roofing tile cutting template (20) is a guide for cutting roof tiles (38) near a valley intersection of two roof sections. The template is for use with tiles having a contoured surface. The template shares the contour of a particular type tile so that the template conforms to the surface of the tile when laid on the tile. The template includes one or more slots (22a, 22b, 22c, 22d, 22e) cut through the surface of the template to provide guides for ruling a cutting line on the tile. The template is positioned on a tile so that the slot corresponding to the geometry of the particular roof intersection intersects a mark placed on the tile indicating one dimension of the final cut tile. The lot is then used to rule an accurate cutting line on the tile.
