Abstract: A roof object is supported on a weatherproofing roof membrane of a building roof structure using a support device including a mounting block and a coupling sheet. The mounting block is a resilient block of material for damping vibrations mechanical roof objects. The coupling sheet is mechanically connected to the mounting block using threaded fasteners which clamp a portion of the coupling sheet to the bottom of the mounting block. The remainder of the coupling sheet spans the bottom side of the block to protect the roof membrane from wear resulting from relative movement between the block and the roof membrane. The coupling sheet is also formed of a bond compatible material with the roof membrane so that the block can be held down onto the roof structure even when the block is not bond compatible with the roof membrane by instead bonding the coupling sheet to the roof membrane.

Abstract: A support block for supporting objects on a roof is a molded elastomeric block with a substantially hollow core. The support block can be used as is or in a system whereby a galvanized steel channel is secured to the top wall of the block accommodating the mating of a variety of clamps. In some embodiments, the block is elongate and generally flat and supports a roof mounted object thereon when two or more blocks are supported parallel and spaced apart from one another with the object spanning between the blocks.
