Abstract
This invention is directed to a tool and a method for using a tool that is particularly useful to individuals engaged in the roofing and roof removal trades. The tool is configured in such a way as to make removal of a shingled roof much easier and with much less strain and effort on the part of the roof remover. The device provides for easy insertion of elongated arms under the shingles in the gap between the boards in the roof base and for a vertical engagement of shingle layers, which makes both inserting the device under the material to be removed and lifting of the layers much easier. After insertion of the device, the shingles are lifted until they are detached from the roof base or the handle of the device may be rotated to lift and disengage the roofing material from the roof base. Prior art devices used for similar tasks all involve horizontal engagement under the roof layers and a chiseling action to release the shingles which is less efficient and more stressful on the workman's body than the present invention.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
