Solar room moves a lot
We have a huge array of skylights over our living room and where the walls meet the ceiling the tape always rips. It has done it for the 23 years we've been here. I suggested using a flexible caulk instead of tape and drywall paste, but all the local handymen who come in for a quote don't seem to get it. They say, when I tape it it will work. But I think it moves due to the fact that it is mostly glass and expands and contracts at a different rate than the walls. It can be 80 degrees in our living room in the winter when outside temp is 20 on a sunny day. Is there a more advanced way to tape or caulk the area where roof and walls meet?
This is caused by the roof trusses moving and is a common problem when trusses are used. I hung drywall for many years and when trusses were used I would not fasten the ceiling drywall along the wall and let the wall hold it up. this would allow the trusses to move without damaging the drywall. You could remove the screws in the ceiling along the wall (or use a large nail punch and drive the nails through the drywall) and re-tape the joint, this works most of the time.
Thanks hadn't considered that. I was thinking of a paintable putty like sealant, like they had in my old office building where the glass walls met the metal. It seems like it could expand and contract without causing cracking. But I guess the putty might want to fully match the paint color... Ever hear of anything like that?
