CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This is a continuation of U.S. patent application Ser. No. 11/775,206, filed 11 Feb. 2004 and presently pending, which claims the benefit of U.S. provisional applications 60/446,277 and 60/486,283, both filed 11 Feb. 2003; the entire disclosures of each of the foregoing are incorporated herein by reference.

BACKGROUND INFORMATION

[0002] The present invention relates generally to covering systems for building structures.

[0003] Thermoplastic covering membranes of a covering system for building structures are typically installed using some combination of mechanical fasteners (e.g., screw and plate combinations which hold roofing membranes to the roof deck), adhesives applied on-site to the covering membrane and/or the building structure to be covered, and hot air. The installation of conventional roofing systems can be quite expensive, even for professional installers.

[0004] Roofing peripherals, such as pipe boots, walkway pads and flashing, that are adhered to roofing membranes in a roofing system using an adhesive or a hot air weld applied to the peripheral at the site of the roofing system installation. This requires a professional installer to have some degree of skill in applying adhesives and working with hot air weld devices.

SUMMARY OF THE INVENTION

[0005] The present invention provides a covering system that may be installed easily and quickly by a non-professional without special tools. An adherent roofing flashing may be used in this or a variety of other covering systems for building structures.

[0006] According to a first broad aspect of the present invention is provided a covering product that includes a membrane including a thermoplastic and a dead load shear capable adhesive on at least a portion of a backside of the membrane in a quantity sufficient to adhere a majority of the membrane to a building structure.

[0007] According to second broad aspect of the invention is provided a method for installing a covering system. The method includes providing a substrate and adhering a first membrane (of the type just described) to a building structure using a first adhesive bonded to at least a portion of a backside of the first membrane. A majority of the surface area of the first membrane is adhered to the building structure.

[0008] According to third broad aspect of the invention is provided a covering product that includes a universal flashing and a dead load shear capable adhesive on at least a portion of a backside of the universal flashing in a quantity sufficient to adhere a majority of the universal flashing to a building structure or a thermoplastic membrane.

[0009] According to a fourth broad aspect of the invention is provided a method for installing a flashing that includes providing a universal flashing and adhering the universal flashing to at least two surfaces that are angled to each other, wherein the flashing is adhered to a building structure and/or a membrane adhered to the building structure.

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The invention will be described in conjunction with the accompanying drawings, in which:

[0011] FIG. 1 illustrates in simplified form a section of a roofing system constructed in accordance with a preferred embodiment of the invention;

[0012] FIG. 2 is a cross-sectional view of one embodiment of a flashing of the present invention;

[0013] FIG. 3 is a cross-sectional view of another embodiment of a flashing of the present invention;

[0014] FIG. 4 is a cross-sectional view of another embodiment of a flashing of the present invention;

[0015] FIG. 5 is a perspective view of an embodiment in which a universal flashing is used in conjunction with two building structure surfaces that meet at right angles;

[0016] FIG. 6 is a perspective view of an embodiment in which a universal flashing is used in conjunction with an exterior corner of a building structure;

[0017] FIG. 7 is a perspective view of an embodiment in which a universal flashing is used in conjunction with an interior corner of a building structure; and

[0018] FIG. 8 illustrates in simplified form a section of a covering system constructed in accordance with a preferred embodiment of the invention in which a covering system is applied to the underside of the upper interior portion of a tunnel.

DETAILED DESCRIPTION

[0019] The following definitions are used throughout this application. Where the definition of a term departs from the commonly used meaning of that term, the explicitly included definition is intended to control.
