Patent ID: 8225557

Claim:
A roof mounting system comprising: a roof substrate; a base member supportable on the roof substrate, the base member defining a first surface positioned substantially adjacent the roof substrate and a second surface spaced from the roof substrate, the base member defining a surface area, the base member including a frustoconical protrusion extending away from the roof substrate along an axis, the first surface forming a frustoconical recess and the second surface forming the frustoconical protrusion, the base member defining a first aperture extending along the axis from the first surface to the second surface, the first aperture substantially centrally positioned in the frustoconical protrusion; a flexible membrane coupled to the roof substrate and coupled to the base member, the flexible membrane positioned substantially adjacent the base member second surface, the flexible membrane defining a surface area, wherein the flexible membrane surface area is greater than the surface area of the base member, the flexible membrane is deformable to substantially conform to the frustoconical protrusion of the base member, the flexible membrane defining a second aperture extending therethrough, the second aperture being substantially aligned with the first aperture, such that the second aperture extends along the axis; a bracket coupled to the flexible membrane, the bracket defining a first surface spaced from the flexible membrane and a second surface positioned substantially adjacent the flexible membrane, the bracket defining an aperture extending from the first surface to the second surface, the frustoconical protrusion extending at least partially into the bracket aperture, and the flexible membrane being deformed by the frustoconical protrusion, such that the flexible membrane extends into the bracket aperture, the bracket being operable to support a roof-mounted assembly, the bracket aperture being substantially aligned with the first aperture and the second aperture, such the bracket aperture extends along the axis; and a first fastener defining a longitudinal axis, wherein the longitudinal axis is oriented along the axis, the first fastener extending through the first aperture, the second aperture and the bracket aperture to couple the base member to the flexible membrane and to the bracket, wherein the base member, the flexible membrane and the bracket are coupled to the roof substrate by at least one of the first fastener and a second fastener, wherein the flexible membrane is at least partially compressed to form a substantially water-tight seal between the base member and the bracket.
