Abstract

Devices, systems and methods for providing a retrofit and repair technique and device for asphalt shingle roof coverings or roofing systems that exhibit premature adhesive tab seal failures. A device can have a handle at one end and a blade tip end at the other end has the blade tip inserted under a shingle to be repaired. The device can dispense a row of “dabs” at a selected location under roof shingle(s). The dispenser can dispense a row of individual “dabs” by a volume container. Alternatively, the dispenser can have a roll with a plurality of rows of pre-made “dabs” of adhesive on removable type paper. Once the blade tip end of the tool device is inserted between upper and lower shingles, the dabs are dispensed by removing the release paper, and the device is pulled out with the release tape is wound up, advancing the adhesive cylinders. Next, the worker can press down on the upper shingle. Additional embodiments can include adhesive adapters having dispensing heads that attach to ends of caulking tubes on caulking guns, or to caulking gun cartridges, and the like.

First claim

We claim:

1. An applicator device for repairing shingle tabs on roofs, comprising:
a main plate-type body having a bottom surface and a top surface, where a first portion of the top surface is an inclined surface at a front lift end of the applicator device, where the inclined surface is at a sloped pitch angle with respect to a second portion of the top surface that is substantially parallel with the bottom surface, the main plate-type body comprising:
a dispenser adjacent to the front lift end, the dispenser having a plurality of channel openings that uniformly dispense a row of adhesive puddles at selected locations between partially unsealed shingles; and
a reservoir configured to direct adhesive to the plurality of channel openings;

an angled metal lift layer having a proximal end attached to the inclined surface of the main plate-type body, where a distal end of the angled metal lift layer defines a tip of the front lift end; and
a base plate removably attached to the bottom surface of the main plate-type body.

2. The applicator device of claim 1 , further comprising a container of liquid adhesive under pressure attached to the main plate-type body.

3. The applicator device of claim 2 , further comprising an air compressor attached to the container of liquid adhesive for applying the pressure to the liquid adhesive.

4. The applicator device of claim 1 , further comprising a squeezable trigger for dispensing of the row of adhesive puddles.

5. The applicator device of claim 1 , comprising a handle attached to a top of the applicator device.

6. The applicator device of claim 1 , further comprising a plurality of parallel channels corresponding to the plurality of channel openings for dispensing the adhesive at the selected locations, wherein each channel of the plurality of channels is approximately 0.03 inches high by approximately 0.06 inches wide, and adjacent channels are spaced apart approximately 1 inch between centers of each channel.

7. The applicator device of claim 1 , wherein the angled metal lift layer is tapered to a thin plate edge at the distal end.

8. The applicator device of claim 1 , wherein the plurality of channel openings correspond to a plurality of cut-outs formed in the distal end of the angled metal lift layer.

9. The applicator device of claim 1 , further comprising a guide stop affixed over the angled metal lift layer, where the guide stop limits an insertion distance of the applicator device between the partially unsealed shingles by contacting an edge of one of the partially unsealed shingles.

10. The applicator device of claim 9 , wherein the guide stop is adjustable to set the insertion distance of the applicator device.

11. The applicator device of claim 1 , wherein the main plate-type body is an aluminum plate.

12. The applicator device of claim 1 , wherein the main plate-type body comprises fingers that extend between the plurality of channel openings.

13. The applicator device of claim 1 , further comprising a feed port disposed in the second portion of the top surface of the main plate-type body, the feed port configured to deliver the adhesive to the reservoir.

14. The applicator device of claim 13 , wherein the feed port is further configured to receive and secure a connector in fluid communication with a supply of the adhesive.

15. The applicator device of claim 13 , wherein the feed port is further configured to receive and secure a connector attached to one end of a caulking gun.

16. An applicator device for repairing shingle tabs on roofs, comprising:
a main plate-type body having a bottom surface and a top surface, where a first portion of the top surface is an inclined surface at a front lift end of the applicator device, where the inclined surface is at a sloped pitch angle with respect to a second portion of the top surface that is substantially parallel with the bottom surface, the main plate-type body comprising:
a dispenser adjacent to the front lift end, the dispenser having a plurality of channel openings that uniformly dispense a row of adhesive puddles at spaced apart locations between partially unsealed shingles;
a reservoir configured to direct adhesive to the plurality of channel openings through corresponding channels; and
a plurality of parallel replaceable tubes disposed in the corresponding channels for dispensing the adhesive at the spaced apart locations;

an angled metal lift layer having a proximal end attached to the inclined surface of the main plate-type body, where a distal end of the angled metal lift layer defines a tip of the front lift end; and
a base plate removably attached to the bottom surface of the main plate-type body.

17. The applicator device of claim 16 , wherein the plurality of parallel replaceable tubes are spaced apart approximately 1 inch between centers of each corresponding channel.

18. The applicator device of claim 16 , wherein the plurality of parallel replaceable tubes include four tubes.

19. An applicator device for repairing shingle tabs on roofs, comprising:
a main plate-type body having a bottom surface and a top surface, where a first portion of the top surface is an inclined surface at a front lift end of the applicator device, where the inclined surface is at a sloped pitch angle with respect to a second portion of the top surface that is substantially parallel with the bottom surface, the main plate-type body comprising a dispenser adjacent to the front lift end, the dispenser having a plurality of channel openings that uniformly dispense a row of adhesive puddles at spaced apart locations between an upper shingle partially unsealed from a lower shingle;
an angled metal lift layer having a proximal end attached to the inclined surface of the main plate-type body, where a distal end of the angled metal lift layer defines a tip of the front lift end;
a base plate removably attached to the bottom surface of the main plate-type body; and
a pivotable roller being moveable between a retracted position and an extended position, the pivotable roller configured to apply pressure to an upper surface of the upper shingle after dispensing the row of adhesive puddles from the dispenser.

20. The applicator device of claim 19 , wherein the pivotable roller is supported by parallel control arms configured to move downward at pivot points in response to activation of a switch.
