Description

PRIOR ART

[0001] While flashings are common in the metal roofing industry, long lasting methods of securing a metal roof do not exist for certain types of common metal roof panels.BACKGROUND OF THE INVENTION

[0002] The present subject matter is designed to allow general contractors to use a boot which appropriately fits most “R” style panels with 1 3 / 16″ to 1⅜″ ribs. In the pre-engineered metal building profession, contractors are having difficulty with “R” panel roof penetrations maintaining a long-lasting seal.

[0003] R panels are commonly used for a wide variety of architectural, agricultural, commercial, and industrial applications. These siding and roofing panels are multi-use and durable compared to other materials. There is a need to be able to install these panels in a manner which maximizes the life expectancy of the panels.

[0004] The typical panel is 36″ wide and anywhere from 5′ to 50′ long. The average rib height on these panels is 1¼″.SUMMARY OF THE INVENTION

[0005] In the following description, numerous specific details are set forth to clearly describe various specific embodiments disclosed herein. One skilled in the art, however, will understand that the presently claimed invention may be practiced without all of the specific details discussed below. In other instances, well known features have not been described so as not to obscure the invention.

[0006] As described herein, the term “pivotally connected” shall be used to describe a situation wherein two or more identified objects are joined together in a manner that allows one or both of the objects to pivot, and / or rotate about or in relation to the other object in either a horizontal or vertical manner.

[0007] As described herein, the term “removably coupled” and derivatives thereof shall be used to describe a situation wherein two or more objects are joined together in a non-permanent manner so as to allow the same objects to be repeatedly joined and separated.

[0008] Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including,”“comprising,” or “having” and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items.

[0009] Unless limited otherwise, the terms “connected,”“coupled,” and “mounted,” and variations thereof herein are used broadly and encompass direct and indirect connections, couplings, and mountings. In addition, the terms “connected” and “coupled” and variations thereof are not restricted to physical or mechanical connections or couplings.

[0010] The present subject matter is a resilient rubber EPDM boot designed to accommodate a metal roofing panel with a 1 3 / 16″ to 1⅜″ rib. In some embodiments, the present subject matter has a trapezoidal standing seam. In other embodiments, the present subject matter has a “mini rib” design which is semi cylindrical in nature.

[0011] The R cap flashing is then affixed to the paneling using a combination of bolts and sealant. The bottom of the R cap flashing is flat to affix to the metal paneling.

[0012] While several illustrative embodiments of the invention have been shown and described, numerous variations and alternative embodiments will occur to those skilled in the art. Such variations and alternative embodiments are contemplated and can be made without departing from the scope of the invention as defined in the appended claims.BRIEF DESCRIPTION OF DRAWINGS
