Retrofit/repair technique for asphalt shingle roofs that exhibit premature adhesive tab seal failures

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.

• 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.
