I'm renovating a bedroom and have made a doorway twice as wide. 80->160 cm.
I have a split-level house with a flat roof built in 1973. According to the building permit documents, the wall I've worked on is not load-bearing since the framework is 2x3 inches.
Should I relieve with a disturbing beam or should I trust the building permit documents?
Since the width of the house is about 7 meters and the roof is supported by 2x8 inch joists (50x200 mm), the marked wall must be load-bearing. There is also no beam in the ceiling above the wall. If the opening is not to be wider than you have already made it, it is easy to install a beam over the actual opening. The fact that it hasn't collapsed yet is because there is no snow at the moment.
