Protective covering for roof mounted systems

Abstract

A protective covering helps to prevent fastener leaks from roof installed fasteners, which are used to mount roofing systems, such as a solar panel installation system, to roofs with a mounting bracket attached to the roof. The protective covering is a portion of flat, malleable waterproof material molded to form a cover, forming a rounded or peaked triangular-shaped structure when viewed from the side. The triangular shaped structure includes a base and a hypotenuse portion where the line of the roof acts as a side which is covered by at least the hypotenuse portion. The hypotenuse portion meets the roof at an angle. The covering is adapted for insertion under portions of a roof shingle, and extends back in a slight rise (downwardly with respect to the roof) to cover the fastener and L-shaped bracket, which the fastener fastens to the roof.

Description

FIELD OF THE INVENTION

This application relates to protective covers for roof mounted systems which help prevent water entry.

BACKGROUND OF THE INVENTION

This invention broadly relates to residential roof mounted systems and, more particularly relates to a protective covering for helping to prevent water entry to structure-underlying roof locations at which the particular roof systems are fastened.

Various roof mounted systems are known. Examples without limitation include roof-mounted satellite antenna systems, roof-mounted solar water-heating systems, roof-mounted air cooling systems and roof-mounted solar panel systems, for example, photovoltaic mounting systems, sometimes referred to as photovoltaic (PV) racking systems. It is also known that building codes require securing PV racking systems securely to a pitched roof's underlying structural members, further requiring that multiple lag screws or through bolts penetrate the roofing material and sheathing in order to secure the PV racking system. Each associated hole is a potential entry point for water into the underlying structure for the entire life of the mounted PV racking system.

One common way of for securing roof-mounted apparatus', such as PV racking systems, to a roof is to mount the bracket to the roof at one end, by using a fastener such as an exposed lag screw or bolt, and attaching the bracket at its other end, or by attaching to an attaching point to the PV racking system. Brackets come in many shapes and sizes, for example, in a form of an L-bracket. While mounting a roof system with a bracket, such as an L-bracket, will generally include sealing the area around the exposed lag screw with a sealant such as waterproof caulking, such seals do not readily last for the life of the roof mounted system, and once installed and attached at the bracket, the roof mounted system will normally prevent access to reseal the mounting hole.

SUMMARY OF THE INVENTION

The present invention was developed to overcome the sealing difficulties of prior art roof mounting systems, such as, for example, solar panel installations, requiring roof fastener penetrations.

The invention comprises a novel protective cover over the roof for covering a fastener and part of an L-shaped bracket utilized on a roof, particularly a slanted roof, for securing a roof mounted system. The cover comprises a sheet of metal, or other malleable of molded material, formed as a triangular member, the narrow end of which may be inserted under a portion of a roofing shingle, and the rear end of which extends over the normally exposed fastener and part of an L-shaped bracket attaching the solar panel installation to the roof. The protective covering is a portion of flat, malleable waterproof material molded to form a cover preferably forming a triangular-shaped structure when viewed from the side. The triangular shaped structure includes a base and a hypotenuse where the line of the roof acts as a side which is covered by at least the hypotenuse, with the hypotenuse of the triangular structure meeting the roof at an angle. The triangular structure is adapted for insertion under a portion of a roof shingle, and extending back in a slight rise (downwardly with respect to the roof) to cover the exposed fastener and L-shaped bracket which the fastener fastens to the roof. An alternative embodiment of the cover may include tabs at all end portions.

Protective covers of this invention in further alternate embodiments are formed with a variety of tapered covering member shapes besides flat, including curved non-sloping or sloping rounded tapered structures as well as peaked tapered structures.

The covers are installed and attached to brackets which are covered but for the part fastened to a rack frame for a solar panel installation.

Alternatively the covers may be installed, without any roof mounting system.

The cover covers the exposed L-bracket affixed to a portion of a roof via an exposed fastener. The cover may be maintained in place by sliding up under portions of the roofing shingles, and/or with an adhesive or sealant, e.g., silicone caulking. The cover should operate to help to prevent water seepage into the fastener opening as long as it remains fixed in place, regardless of the longevity of the sealant/adhesive.

DETAILED DESCRIPTION OF THE DRAWINGS

FIG. 1 shows a protective cover 1 of this invention. Although many material choices and fabrication techniques are possible such as a variety of molded plastic materials, sheet metal (such as aluminum or copper) cut and folded or punch pressed into shape are preferred. Sloped surface 2 is supported by triangular sides 3. Flanges 4 on each side are designed to be fitted underneath the top and side portions of a shingle, which is cut to fit the contour of surface 2. Optional back edge 5 forms a drip edge and further shields the roof fastener. Edges 6 at the intersection of sides 3 and flanges 4 as well as the front edge 7 are preferably sealed against the shingle with appropriate sealant.

FIG. 2 shows the placement of four covers 1 over mounting brackets for a solar collector on pitched roof 12. Note that the top layer of shingles 13 are cut around each cover 1 at the mounting sites 14.

FIG. 3 shows a side view of solar panel 16 mounted on roof 12 over shingles 13.

The fastener area is enlarged in the detail shown in FIG. 4. L-bracket 18 is attached by lag bolt 19 to roof 12. Collector mounting bar 17 is attached via fastener 20 to bracket 18. Cover 1 (shown in crossection) covers the head of normally exposed fastener 19 which is now covered under sloped section 2. A small portion of sealant 22 is seen at the front end of cover 1.

FIG. 5 shows a section of roof with two covers 1 installed inside the cut-away contour of top shingles 14 and sealed with a bead of sealant 22 on the front edge and both sides.

FIGS. 6-8 show a top side and front view respectively of an alternate embodiment of cover 30 of this invention. This cover has a continuous flashing flange 33 that surrounds the sloping area 32 on all three sides including the front. Optional back drip edge 34 serves the same function as edge 5 of cover 1. Contour 36, which is located at the interface of front of section 32 and sides 35 with flange 33; defines the location of sealant bead that would be applied to seal cover 30 with shingled surfaces.

FIGS. 9-20 show several embodiments of covers of this invention with alternative shapes besides the flat sloping cover of the embodiments above. An optional rear drip edge can be appended to the rear of any of these embodiments.

The embodiment 40 of FIGS. 9-12 is best understood in geometric terms as a curved hollow cylinder of circular or oval crossection tapered with a domed front as truncated by a plane parallel to the cylinder axis. FIG. 9 shows a perspective view while FIGS. 10 and 11 show a side elevation and a top view respectively. A flange 43 is shown around three edges of the cover. Dome closed end 42 and cylindrical cover 41 complete the embodiment. FIG. 12 shows a detail of an installation with cover 40 shown in crossection. The interior 45 is shown in a side view.

FIGS. 13-16 show cover embodiment 50 in various views. The geometry here is best described as a curved hollow tapered cylinder of round or oval crossection as truncated by a plane angled to the axis and piercing the end at median and a side. The round contour 51 is shown surrounded at three edges by flange 53. An optional drip edge 54 is also shown at the rear. FIG. 16 shows the details of an installation with cover 50 shown in crossection. The sloping contoured interior 55 is shown in this view.

Other cover shape embodiments with sloping peaked shapes are shown in FIGS. 17-20. Shape 60 (FIGS. 17-18) has two triangular sides 61 joined at a central peak. Shape 65 is similar to 60 having a central peak and sloping tapered down toward the front, however it has vertical sides 67 below sloping triangular roof members 66 joined at the peak. Other variations such as a gambrel roof with a symmetrical two-sided shape having two slopes on each side. The upper slope is positioned at a shallow angle, while the lower slope is steep. An arched roof with straight vertical sides is also possible.

In the foregoing description, certain terms and visual depictions are used to illustrate the preferred embodiment. However, no unnecessary limitations are to be construed by the terms used or illustrations depicted, beyond what is shown in the prior art, since the terms and illustrations are exemplary only, and are not meant to limit the scope of the present invention.
