hi, got to remove a bedroom wall and just been into the loft and seen it goes all the way up and supports what i think is a purling...a long piece of timber that runs left to right NOT front to back of the house, its only 2 feet off the truss and sits on a single skin 2 brick pillar. it is tied into the wall 1 end and sits on this pillar at the other, can i put a piece of timber say across 3 trusses then prop it solid will some more timber then remove the wall, or do i need to find a way to r.s.j it, the r.s.j way is a last resort
