The ornamental design for a roof constructed of triangularpanels, as shown and described.
FIG. 1 is an isometric view of a roof constructed of triangular panels;
FIG. 2 is a side view thereof;
FIG. 3 is a top plan view thereof; and,
FIG. 4 is a bottom plan view thereof.
The left, right, front and rear side views of a roof constructed of triangular panels are substantially identical; therefore only one representative side view is shown.
A characteristic of the design is the formation of a three-dimensional roof structure from four like substantially flat triangular panels, each of the panels having two edges substantially free of contact with other of the panels and having one edge in contact with the back face of an adjacent panel along a portion of the edge.
