I noticed that my truss ends were severely uneven After I ripped off my facia boards and installed my first piece of strapping for my new steel roof. I knew this problem existed but I convinced myself that it was simply because the cottage foundation had heaved. Now my foundation is level and the truss are still out of whack. When I run a string from one end to the other there are spots that are out 1.5″. The worst spot is where the addition meets the original building but there are uneven spots everywhere. I’m just wondering what unevenness is acceptable and what needs to be fixed. Should I simply shim my strapping to ensure a flat roof or do I need to level my truss line? And if that’s the case what is the best way? Any input is appreciated!

I've seen many roofs out worse than that. The question is, what are you willing to live with, in terms of appearance, and how much do you think you can improve things with the measures you're considering?
Dan, I just don't want the steel to take the same shape as the roof line. Looks terrible. I also don't want any voids between the steel and strapping because eventually I would like to be able to walk on it if I needed to without poping screws. So I guess functionality is still the biggest concern but esthestics is also important.
huh???
Is it just the tail end of the trusses that is wonky or is the wall plate under the trusses also wavy/
The worst of it is basically where the original cottage meets the addition. It seems to be 1.5" higher than the lowest spots. The walls under the truss and rafters are in good shape. I'm wondering if it makes sense to shim my strapping around the eaves and hope the problem corrects itself as I approach the ridge. I know that's a lot of shimming and it would take a long time.
