Patent ID: 8316617

Claim:
A method of supporting a roof object on a roof of a building comprising a rigid supporting structure and a roof membrane bonded to an upper surface of the rigid supporting structure so as to be arranged for weatherproofing the supporting structure, the method comprising: providing a support device comprising a mounting block formed of a resilient material which differs from the roof membrane and a coupling sheet formed of a resilient material which is arranged to be bonded to the roof membrane in which the mounting block is coupled to the coupling sheet using a first mechanical connection; bonding the coupling sheet to the roof membrane such that the coupling sheet is the only connection between the support device and the roof of the building and such that the first mechanical connection does not penetrate the roof membrane; wherein the first mechanical connection comprises a rigid fastener clamping a portion of the resilient material of the coupling sheet to the resilient material of the mounting block at a location spaced above a bottom side of the mounting block such that the rigid fastener does not contact the roof membrane; and coupling the roof object above the mounting block using a second mechanical connection.
