The modular roof structure includes a grid system with a plurality of parallel beams and a plurality of roof tiles provided on the parallel beams in an overlapping manner. The parallel beam has an engaging protrusion that projects upward. The roof tile has a front end that is provided with a hook portion to receive the engaging protrusion of the parallel beam, and a rear end which is provided with a projection to abut with the hook portion of an adjacent roof tile and a covering member which shields the hook portion from rain and sunshine.
A retaining clip for use in combination with building siding panels of the type which simulate wooden clapboard. The siding panels have two or more longitudinal outwardly and downwardly depending declination portions. The clips comprise thicker main body portions attachable to the building-side face of declinations of the siding panels, and thinner flexible arm portions. A protruding stop detent extends from the face of the flexible arm portion. The detent is spaced apart from the main body portion of the retaining clip. Building siding panels having retaining clips of the invention are also provided, as are methods of siding a building with the modified siding panels. The modified siding panel assemblies preferably have retaining clips attached to at least one end of each declination portion of the siding panels in an orientation which permits insertion of the declination portion of a horizontally adjacent panel between the flexible arm portion of the retaining clip and the building side of the declination portion of the panel to which the clip is attached. A detent can be used on the face of the retaining clip to resist horizontal movement of the inserted panel as the panel is inserted, but such detent does not prohibit horizontal movement of the inserted panel, thus providing for thermal expansion of the mounted siding panels.
