I have the same ceiling and tool but the tool is really made for siding so I found the angles are not right and the hook edge is too blunt to slip in between the overlap, so I ground down shorter the hook edge to allow it catch the overlap edge better , I also sharpened the inside of the hook to a putty knife edge..it did work better but it was very hard to break loose. (at the initial unzipping It’s kinda like breaking the bead on a tire) also I think warming with a heat gun will allow the break to be easier as long as you don’t overheat too much and on too narrow a spot because it will just bend without unzipping.. I would feel as I heat to make sure it’s evenly getting warmed for at least a foot on either side….PS I used a heat gun as careful as possible but it’s too hard to judge when you go too far as the material is so thin it distorts once you pull at it ,so unless your doing it to get to room temp I wouldn’t do it..I reheated and tried to reshape, its almost the same but it’s impossible to get it back to factory profile
@@everythingisbroken7280 Figured out a way to do it btw ! Just to update. We heat gunned it to make it more elastic. Not too much to warp it just to worm it up. The following 2 buildings we did went easier and didn’t need to heat. They didn’t leave 1/4 gap that you’re suppose to leave on first building. Thanks tho the vid did help !
