WEATHER PROTECTOR FOR ROOFS Filed Aug. 20, 1963 Pics. 5

INVENTOR. KENNETH D. TMAN BWQJQQQ,

ATToRNEy United States Patent 3,210,896 WEATHER PROTECTOR FOR ROOFS Kenneth D. Detman, 357 Morgan Ave., Mobile, Ala. Filed Aug. 20, 1963, Ser. No. 303,451 6 Claims. (Cl. 52-22) (Granted under Title 35, US. Code (1952), sec. 266) This invention described herein may be manufactured and used by or for the Government for governmental purposes without the payment to me of any royalty thereon.

The weather protector for roofs described herein pertains to a secondary protective covering supported a spaced distance from a conventional roof. This secondary roof is not intended to be a waterproof roof covering, but rather a flexible, ventilated, windproof sun and weather shade for most conventional roofs.

The purpose of this invention is to provide a covering for roofs supported on spacers a fixed distance above the roof to give protection to the roof from the elements.

Another object of this invention is to describe a roofing module that can be easily applied to a standard roof.

Still another object of this invention is to provide a series of roofing modules that will have ventilation means between each module.

One of the main problems with roots is that they are affected by the continuous exposure to the sun rays, and the direct erosion effect of wind. The sun and Wind cause the roofing surface to bake out and crack over a period of constant exposure. This invention is concerned mainly with a secondary roofing that will protect the main roof of a building. This secondary roof is composed of separate overlapping modules that are attached to the main roof at a distance above the main roof by spacing and fastening means. The details of this invention will become more apparent in the following description of which:

FIG. 1 is a top view of the assembled modules in an overlapping fashion;

FIG. 2 is a view taken on the line 2--2 of FIG. 1; and

FIG. 3 is a top view of a single module showing the three serrated edges In the top view of the composite protective roof structure of FIG. 1, the individual hexagonal plates 1 are arranged in an overlapping fashion. Spacer members are attached to the plates with a fastening means 5 in the center of each plate. The top three edges 3 of the plate 1 are underneath the adjacent plates with turned up serrated edges giving air passages for the air to circulate through the protective roofing. This protective roofing is not meant to be waterproof and there is no sealing means at the overlapped portion of the plates. However, in the normal rainfall, water will not run under the protective roofing to a great extent. Only in a driving rain will an appreciable amount of water get under the protective roofing. In the event that water does get beneath the protective roofing, it will run off the main roof in the same way as if there were no protective roofing.

After the installation of the protective roof, the main roof never receives the direct rays of the sun and therefore keeps the roof and interior temperatures considerably lower than those of unprotected roofs. Also, the main roof with this protective roofing will last several times longer because the sun cannot bake out the waterproofing agents in the main roof.

This protective roofing is essentially a series of overlapping plates, made of either noncorrosive metal, plastic, waterproof fiber, reinforced ceramics or other waterproof and fire resistant material. These plates may be of any shape or size, with a hexagonal shape the most favored. These plates are supported above the roofing material by suitable brackets or supports which are attached to the roof surface through waterproof fastening means. Spacing of the plates is such that they overlap like shingles at some average fixed distance from the roof as required by the type of roof.

The usual application of this protective roof will be over a new standard roof. On wood roofs the brackets can be attached by serrated nails or screws through suitable rubber or plastic gaskets in contact with the roofing surface. On metal roofs, bolts and studs using similar gaskets may be used. On other types of roots, a waterproof adhesive may be used or any of the previously mentioned fasteners.

FIG. 2, which is a side view of the main roof 8 with the protective roofing installed at a spaced distance above it. The hexagonol plates 1 are supported on spacer member 4, the ends of which have been bent at right angles to the main body of strap support spacer 4. Through a hole 2 in plate 1 screw 5 connects the plate to the support. Support 4 is attached at its other end to roof 8 by means of screw 7 through a similary bent end portion. Gasket 6 forms a watertight seal between support 4 and roof 8. Strap support 4 is only one of many types of spacers that may be used within the scope of this invention. It is essentially a flat piece of strap iron which has its ends bent for connection with the plate and the roof 8 which also has a hole in each bent end portion for fastening means.

Fastener 10 is another type fastener that can be used as spacing the plates above main roof 8. It is comprised of a rod like body having a pointed end 13 and a tapered fastening end adapted to receive a nut 11. At a distance from this pointed end is a flange or stop to prevent the fastener from being driven too far into the roof 8. Beneath this flange is a gasket 12 forming a watertight seal. The spacer at the far right of FIG. 2 is similar to the spacer 4 at the far left of FIG. 2 except for the fastening means which is a toggle, molly or standard bolt 14 holding the spacer to roof 8.

The spacing of the protective roof above the main roof 8 depends on the type of roof involved but a minimum of about 2 inches gives proper circulation between the main roof and the protective roof.

The overlap of the hexagonal plates over one another is not critical but about a 4 inch overlap will allow most of the water to drain off the protective roof and also provide adequate ventilation between the hexagonal plates. The forward edge of the plate which is serrated and up turned gives adequate ventilation if the turned up lip is about A1. inch and the serrations are about 4 inch but here again these dimensions are not critical.

The top view of a single hexagonal plate is shown in FIG. 3 before the serrated edges are upturned. Three of the six sides of plate 1 are stamped out with serrations. The edge 15 has the deepest serrations which are the same depth all across edge 15. These serrations can be any suitable depth but here are about 4 inch deep. Edge 16 has serrations which begin at about 4 inch deep at the juncture of edge 15 and edge 16 and continually decrease in depth along edge 16 to a zero depth at the opposite end of edge 16. Edge 17 is similarly serrated. If the upturned lip on the three

edges

15, 16 and 17 is equal in height to the depth of the serrations then the upturned li-p will be highest along edge 15 and taper off to zero along edges 16 and 17. These three serrated edges will fit under the adjacent plates and will also give ventilation passages along all sides of the overlapping joints between the plates,

When these individual plates are attached to a spacer secured to the roof and the plates arranged in an overlapping fashion they Will give a secondary roof that Will shield the main roof from the continual exposure to the elements. This secondary roof will prolong the life of the main roof and also have an insulating effect on the building.

I claim:

(a) a series of overlapping plates having upturned serrated portions along a portion of the perimeter of each of said overlapping plates and a flat, uninterrupted portion along the remainder of the perimeter, said flat, uninterrupted portions of each plate over lapping the serrated portions of another adjacent plate for promoting free circulation of air to all areas between said roof and said covering while protecting said roof and said covering from adverse elements; and

(b) means supporting said overlapping plates above the surface of the roof.

4. A flexible, ventilated deflective covering in combination with a roof comprising:

(a) a series of overlapping hexagonal plates having upturned, serrated portions on three sides and flat, uninterrupted portions on the remaining sides, said flat, uninterrupted portions of each plate overlapping the serrated portions of another adjacent plate for promoting free circulation of air to all areas between said roof and said covering while protecting said roof and said covering from adverse elements; and

(b) means supporting said overlapping plates above the surface of the roof.

5. A flexible, ventilated, deflective covering in combination with a roof as recited in claim 4 wherein said overlapping plates are provided with av centrally located aperture receiving said support means.
