Roof mounting system

Abstract

The present invention relates to a roof mounting system with a locating and waterproofing device ( 100 ) which is formed from a water impermeable medium. The device has a short edge ( 104 ) which is dimensioned to rest against and be secured to a batten ( 121 ) and a long edge ( 106 ), whose upper portion rests on an upper surface of the batten ( 121 ). A lower portion of the locating and waterproofing device rests on a lower slate or stone ( 10 A) and is sandwiched between the lower slate or stone ( 10 A) and an upper slate or stone ( 10 B) so that a continuous barrier ( 102 ) is formed along the long edge ( 106 ) to provide a water resistant barrier and to create a void ( 116 ) between the lower slate or stone ( 10 A) and the upper slate or stone ( 10 B).
