Abstract
A roofing system has individual roofing panels that include a metal outer skin surrounding an insulation layer, a factory-applied protective membrane of polyisobutylene, and interlocking components for providing a rigid roof that is self-supporting and requires no sub-deck. The panels with pre-applied protective membranes are adapted to be factory-shipped to a job site so that assembly and sealing can be achieved in a one-step process.
Claims31
A structural roof panel comprising
- an upper membrane having a generally rectangular shape;
- a lower membrane having a similar shape as, and being positioned below and generally parallel to, said upper membrane,
- an intermediate section between said upper and lower membranes;
- and
- an outer membrane fixed to the upper surface of said upper membrane.
A roofing system for assembling a roof directly upon a series of generally parallel, laterally-spaced elongated structural support members, said system comprising
- a series of generally rectangular panels each adapted to span at least the length of the distance between a successive pair of said structural support members;
- each said panel comprising a first male tongue and a first female groove on one sidewall, and a second male tongue and a second female groove on an opposite sidewall, thereby adapting each panel to be adjacently positioned and interlocked with another panel by mating of said first and second male tongues with said first and second female grooves;
- and
- each said panel comprising a membrane of polyisobutylene fixed to the top surface of each panel.
A method of making a structural roof panel, said method comprising
- providing an upper membrane;
- providing a lower membrane,
- providing an intermediate layer between said upper and lower membranes;
- and
- adhering to said upper membrane an outer membrane of polyisobutylene.
A method of assembling a roof structure, said method comprising
- providing a plurality of roof panels each having a pre-applied, weather-resistant outer layer;
- placing said roof panels adjacently with respect to each other;
- and
- structurally attaching said panels to each other.
