Putting up interior wall with truss roof in existing home

Asked Mar 1, 2012, 06:54 AM — 7 Answers
I would like to put up an interior wall to separate my dining rm from the living rm. The dining rm has an 8ft ceiling that runs parallel to the wall I want to put up. I had asked the people who build the home and they said no problem. I have read so many articles on truss uplift I don't know what to think anymore. The ends of the new wall would connect to the side walls.My concern would be the top plate. I have access to the attic to put blocking in to nail the plate to but am afraid of the truss uplift. Any ideas please.

Top plate with truss roof
If putting up a new wall in a room with a ceiling already up and a truss roof wouldn't the new top plate go up if you have truss uplift? How to solve this problem or what to do.

I don't know how many Habitat houses I have built, all with truss roofs, but we have never experienced an issue with interior walls either parallel or perpendicular to each other.

Truss lift is a moisture issue so maybe where you are working moisture isn't any issue.

If the new wall goes across the trusses, screw the top plate to the truss and screw the bottom plate through the floor into the joists. You onle need a single plate for a non bearing wall.Use 3" coarse thread drywall screws. If it parallels the truss and you have attic access, place sleepers between the trusses and then screw to the. If you are really concerned, why not install a partiton wall that doesn't tie to the trusses? Used to be very popular in contemporary homes and gives you airflow across the top.

Yes,between the trusses and flush with the ceiling. Should be about 22 1/2" long and16-24" apart.
