Abstract
A crush resistant seamless roofing system is formed by a layer of adjacent panels having loose joints filled by expanding rising foam adhesive, which is trimmed to remove excess foam adhesive above a top plane of the roofing system. The roofing system thus formed is covered by a fabric layer and a coating. Further, the seamless roofing system is combined with a base layer, located beneath the panels, the base layer comprising bonded panels of a lightweight fireproofing material, resistant to moisture and foot traffic.
Claims24
A combination of roofing layers comprising:
- a hardened foam roofing panel having a first block of polyurethane foam with a top surface, a bottom surface, and at least one indented periphery;
- said top surface having an integral layer of fabric bonded to said block;
- at least one base layer;
- and
- said bottom surface of said first block being in contact with said at least one base layer.
A method of forming a layered roofing system comprising the steps of:
- applying a core layer;
- applying an integral foam layer;
- and
- applying a reinforcing mesh, a portion of said foam layer penetrating upward through said reinforcing layer.
A method of installing fire resistant roofing tiles comprising:
- a) spraying a foam rising adhesive on a surface;
- b) waiting for said foam rising adhesive to obtain a creamy consistency;
- c) applying a first tile panel and an adjacent first subsequent tile panel to said surface;
- each said tile panel having a respective fire resistant layer adhered thereto;
- d) waiting for said adhesive to cure and rise within a joint formed between said first tile panel and said first subsequent tile panel;
- e) applying further tile panel and subsequent further tile panel to said surface;
- f) waiting for said adhesive to cure and rise within further joints formed between said first subsequent tile and said further tile panel;
- g) repeating steps “c”, “d” and “e” and “f” on next subsequent pairs of tile panels until said foam adhesive completes rising between said joints and accumulates as debris above a plane formed by said tile panels accumulated in a seamless configuration;
- h) removing debris formed by said foam rising adhesive from the top surface of said tile panels;
- and,
- i) applying an elastomeric coat to the top surface of said joined, seamless accumulation of tile panels.
A fire-resistant, crush resistant and puncture resistant seamless waterproof roofing system comprising a plurality of adjacent cured foam panels attached to a roofing by a foaming adhesive bonding said panels to a substrate of said roof, each said panel having a respective fire resistant layer adhered thereto;
- said adhesive rising between said panels, sealing said panels to each other by expansion through loose inter-panel joints between said panels,
- said panels having an on-site coat of elastomeric sealing material thereon, said coat of elastomeric sealing material covering a fabric layer above each of said panels.
