Description

    CROSS-REFERENCE TO RELATED APPLICATIONS
  • Not Applicable.
  • STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT
  • Not Applicable.
  • FIELD OF THE INVENTION
  • This invention relates to a roofing system, and more particularly to a roofing installation system integrated with a gutter system.
  • DISCUSSION OF RELATED ART
  • Solar electric systems are the most environmentally friendly way of generating electricity for heating and other residential applications. Varieties of roofing installation systems for supporting solar energy collecting panels are available on the market. The existing roofing installation systems can be mechanically complicated. Most of the systems utilize metallic frames and mechanical fasteners for anchoring the solar panels to an existing roof structure. The existing systems may use a large number of penetrating mechanical fasteners on the roof deck, which can compromise the watertight integrity of the roof. Some conventional mounting systems cannot be installed on sloped roof structures.
  • U.S. Pat. No. 7,806,377 issued to Strizki on Oct. 5, 2010, discloses a modular solar panel mounting system. The mounting system for frameless solar panels is comprised of a plurality of base-mounting members and a plurality of mounting brackets. Each of the mounting brackets includes one or more elongated bars having a center portion, a flat top plane and a flat bottom plane. Each of the elongated bars includes slotted holes formed on either end of the elongated bars. The mounting brackets are fastened to the base mounting members through the slotted holes. The invention is designed to mount solar panels on the ground or on essentially flat rooftops by utilizing ground mounting pans as the base mounting members. However the mounting system is not designed to be installed on slanting roofs where proper drain channels have to be provided to drain out the rain water or water from melting snow.
  • In addition, U.S. Pat. No. 6,877,287 issued to Szacsvay on Apr. 12, 2005, discloses a device with flat, panel shaped components. The flat, panel shaped components may be photovoltaic elements. Adjacent rows of the flat, panel-shaped components are disposed below one another, overlapping in a shingle-like way, to form a covering for a roof or a facade. The flat, panel shaped components are preferably designed as photovoltaic elements. Disposed under the components in each case in the region between adjacently situated vertical rows is a section forming an open channel to receive and drain water running off adjacent components. The section has sawtooth-shaped lateral parts on which the components are borne in their shingle-like configuration. By means of the lateral parts, a clearly defined support for the components is formed. However the invention may not be suitable for supporting slates or photovoltaic elements of larger dimensions.
  • U. S. Pat. Application No. 20100236183 entitled to Cusson on Sep. 23, 2010, describes a support system for solar panels. The support system for solar panels or other panel-like structures are fabricated by maintaining precise parameters. Through use of a collapsible folding, support frame which is preassembled to precise tolerances at a convenient staging site before being collapsed for shipment. Installation on flat roofs is facilitated through the use of a roof interface frame which rotatably supports the panel support frame of the support system and folds along with it at the assembly, staging site. Even though the installation is simple and faster the drainage system of the invention may not be effective to drain away the rain water or snow melt.
  • Therefore, there is a need for a roofing installation system that is adaptable to various environments; can be easily configured to accommodate existing roof installations; can be applied to different types of roofing configurations, both flat and sloped. Also the roofing installation system should be aesthetically pleasing and able to support larger sized solar modules available on the market. Moreover, the roofing installation system should not compromise the watertight integrity of the existing roof. The present disclosure accomplishes all these objectives.
