Light weight beams that don't appear to do anything? (https://i.stack.imgur.com/nTPd3.jpg)
Please can someone tell me if the beam in the photo that is cracked needs to be replaced? Can I just screw a piece of 3by2 down the inside of it to reinforce/repair? I just had a roofer over and he seems to think that I can do the above and that these light weight beams are not doing a lot?
