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

摘要

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.
