In use, as can been seen in Figure 7, a roofing sheet 10 is held at an angle to an adjacent roof sheet 38, that has been fastened to the purlin 18, so as to allow the mounting component 12 and second extension 34 of the covering component 14 to be complementally received by the roofing sheet 10 in a snap fit engagement. Once overlapping has occurred the first roofing sheet 10 is laid down and fastened to the purlin 18 with a securing screw 42. A user continues to overlap the roof sheets 10 until an entire roof support structure has been covered by the overlapping roof sheets 10. Due to the overlapping of the roof sheets 10, the fastening of the base 16 to the purlin 18 is concealed which eliminates possible leakages that may occur.
Although only certain embodiments of the invention have been described herein, it will be understood by any person skilled in the art that other modifications, variations, and possibilities of the invention are possible. Such modifications, variations and possibilities are therefore to be considered as falling within the spirit and scope of the invention and hence form part of the invention as herein described and/or exemplified. It is further to be understood that the examples are provided for illustrating the invention further and to assist a person skilled in the art with understanding the invention and is not meant to be construed as unduly limiting the reasonable scope of the invention.
The inventor regards it as an advantage that the invention provides an elegant solution to thermal expansion and contraction experienced by overlapping roof sheets once assembled by the longitudinal displacement of the mounting component and covering component. The inventor regards it as a further advantage that the
WO 2017/214642
PCT/ZA2017/050034 valley of the invention provides a greater water drainage area. The inventor regards it as yet a further advantage whereby damaged sheets in the middle of a roof can be easily replaced with a new roof sheet. The inventor regards it as an advantage that the invention greatly increases the loading strength of roof profile with greater spanning capabilities and resistance to removal from the roof sheet supporting structure.
