System for overlaying the overhang of a building
A system for protecting the overhang portion of a building comprising sheets of impervious material largely pre-formed before delivery to job site to minimize on-site shaping and forming, including the optional use of one or more pre-formed pieces to be fitted together on-site, and also including an optional S-fold connector to join together side-by-side sheets of the impervious material.

It is generally desirable and customary in construction of residential buildings, and some commercial buildings, to extend the roof (usually but not always slanted) beyond the edge of the building structure it covers. This extension results in an overhang which allows rainwater and other precipitation to fall off the roof or into an attached gutter with relatively little roof run-off touching the exterior sides of the building. Of course, winds can blow moisture, during a rain, against the sides of a building, sometimes up under the overhang, although the overhang reduces the amount of such moisture contact. Furthermore, the heat of the sun can cause damage to paint on and under the overhang and in other nearby areas, notwithstanding the overall protectiveness of the overhang system.
To minimize maintenance and to shield exposed, and generally wood, components of overhang systems, such exposed components have often been overlaid with metal sheet or other relatively imperious material, often prepainted with permanent or semi-permanent paint or baked-on enamel. Major problems associated with the use of metal and other types of overlay materials have been that: (1) they in many cases must be fabricated in the field in order to configure and conform them to the particular shape of the structure to which they are affixed; (2) the various difficulties of on-site fabrication must be overcome, including cutting, shaping, attaching, connecting adjacent pieces of the overlaid covering, providing vent spaces, and otherwise producing an attractive and effective exterior appearance in the overlaid areas; and (3) on-site fabrication has not heretofore produced innovative configurations which tend to maximize the protective effectiveness of the overlays.
In the past, various approaches have been proposed to produce improved overlay systems for the overhang portions of a building, of which examples are: Brochu, USP Application Publication No. US 2005/0193642 A1; Gibson, U.S. Pat. No. 6,026,616; Hicks, U.S. Pat. No. No. 5,941,028; Lloyd-Jones, U.S. Pat. No. 4,347,691; Maloney, U.S. Pat. No. 4,092,808; Martin, U.S. Pat. No. No. 6,955,010 B2; Merkin, U.S. Pat. No. 3,826,048; Norton, U.S. Pat. No. 5,560,158; Schroter, U.S. Pat. No. 3,181,275; Strength, U.S. Pat. No. 5,729,933; Zaccagni, U.S. Pat. No. 5,797,220; Zaccagni, U.S. Pat. No. 5,950,375; and Zacagni, U.S. Pat. No. 5,735,084. Some of the systems heretofore proposed contemplate coverage of not only the overhang areas but also all or most exterior areas of the house. Others provide for cornice pieces which are primarily decorative; such as Norton and Strength, supra. Others are concerned with facilitating the ease of bending metal cladding or overlays, such as in Zaccagni (U.S. Pat. No. 5,950,375). Others focus on ventilation issues, such as Hicks and Martin. In each case, the other inventors have focused on systems which implicitly or explicitly are intended to start on or around the fascia face at the end of the roof rafters and then proceed toward the vertical side of the building where the overlay terminates in some manner that is usually incidental to the primary protective purposes of the overlay. An unarticulated premise of many other systems is that primary attention should be given to covering and protecting the fascia and soffit areas of an overhang, without being much concerned about the terminus of the overlay near the side of the building.
BRIEF SUMMARY OF THE INVENTIONAn object of the present invention is to provide an effective configuration of overlays or cladding which can be largely pre-cut prior to delivery to the installation site, facilitating ease of in-field construction, and at the same time enhancing the level of protection against precipitation and insect or animal damage afforded thereby.
BRIEF DESCRIPTION OF THE DRAWINGS
In the case of the present invention, the relatively impervious overlay material fits under frieze 6 in area 12 and forms a drip edge 11 just before turning vertically to cover a part of the outward-facing vertical side of frieze 6 in the area 10 (the overlay can also extend beneath the soffit 14 without turning vertically to cover any of the outward-facing vertical side of the frieze), then extending generally horizontally in area 9 below the soffit 14 to point 7, where a drip edge can be formed in that general vicinity or where the overlay can extend generally vertically in area 8 to cover outer face 4 of fascia 5. Drip edges, whether used at points 11 or 7 (or both) can either be an integral part of the basic overlay material, or they can be pre-formed and attached to the basic overlay, as desired. As will be explained later in the discussion of
Although it might not be apparent, when viewing the overlay after installation, the overlay of the present invention is designed to be installed beginning with the underside of frieze 6 and working outwardly toward the fascia 5. Because friezes vary little in thickness, it is possible to pre-form, in factory or shop, a first piece overlay strip which is pre-configured to accommodate the frieze at one end, with drip edge, followed by a vertical upturn to cover a part of the outer face of the frieze, and then extending in a length long enough to cover the soffit. The only significant variable on this first piece of the overlay material is the length of the soffit (measured from side of the building to the fascia). Thus, it is possible to produce a first overlay piece which is standard for virtually all overlay configurations, except for the soffit dimension (and perhaps an optional drip edge addition); therefore the only in-field adjustment which must be made is to bend such first overlay piece at the outer terminus of the soffit. A second overlay piece is required to assure complete coverage of the fascia. However, fascia boards are generally found in a few discrete dimensions; consequently, by pre-forming, in factory or shop, sets of these second pieces in the common discrete dimensions corresponding to fascia dimensions, it is possible to have pre-formed second pieces that join with the first pieces to completely cover the portion of the overhang system desired to be covered with those two pieces, with no forming, cutting or configuring required in the field except for a single bend to adjust the first piece to the dimensions of the soffit.
The utility of a drip edge, shown at point 11 (but which could also be placed at other points along the overlay, such as at point 7) is that it helps to shield somewhat vulnerable places from precipitation, and provides a point for water reaching the drip edge to drop off, since the water will not likely run upward on the back (shielded) side of the drip edge. Thus, the drip edge at 11 is made by a simple bend and back loop of the overlay material, or it can optionally be added as a separate piece. It protects the somewhat vulnerable point where area 12 meets the side of the building just below the frieze, where moisture might be able to get in, but for the shielding effect of the drip edge.
