Found a new-construction home I want to purchase, but I have serious concerns about the roof trusses and ceiling joists. The house is completed on exterior (bricked, windows, and roof completed) but interior is unfinished. Studded walls show floor plan laid out, but no drywall, no electrical/plumbing/insulation/cabinetry/fixtures, etc. House completely unfinished on interior other than studded walls throughout and sub-floor. Center of home is one very large, open space for main living space- living/kitchen/dining, and measures 33.5'x 20'.
My biggest concern is this: The ceiling joists(which are part of the roof trusses) run the direction of the 33.5 feet in the room, and are only made of 2"x4"s (seems way too small to me), which are connected by metal brackets which connect the 2x4's end-to-end, and there is obvious sagging in places along these runs of 2x4's. Obviously, once you hang drywall to make your ceiling, you would have even more sagging! There are no cross beams to add support anywhere in the 33.5'x 20' room. The roof trusses are made of 2x4's also, and all of this is spaced on 24 inch centers.
Someone has made chalk lines along the worst sagging areas, and the chalk line is over one third up the board in places, so cutting them to even them out would weaken the structure I would think (someone told me you could do that!)
I'm just trying to decide if I should run for the hills, or is this not a deal breaker? Absolutely everything else about this house and property is perfect, as we've been looking for well over a year now! Any information from those who're knowledgeable about roof trusses and ceiling joists in new-construction would be very much appreciated!
