I own a home that was built in 1938. The rafters are sagging. I checkedd the way the roof was built and this is what I found. 1) The walls are not plumb. Between the bottom of the wall and the top of the wall the difference is between 1 and two places. Should I be concerned. 2) Two collars ties are places on the rafters. One on the top One on the bottom. 3) The ridge is a 2 by 4. 4) The rafters are 2 by 4 24 inches on center. 5) A purlin is place between the ridge and the bottom collar tie.
I had roofers look at the roof. No one wants to do the job.

What are my options.

Thanks for the help

Your description is very difficult to understand. If you would like a professional opinion contact me through the “Expert Advice” section of this website. If you want, you can send me some photos there. Other means of contacting me can be found on my website: www.consultationdirect.com. How far out of plumb are your walls? How far apart are the collar ties? And I do not understand the position of the purlin you are talking about. How bad is it sagging and how long are the rafters? Give me some more information and I can advise you what needs to be done to repair your problem.

Hi ways,
The top piece that you mentioned sounds like a collar tie but the bottom sounds like a ceiling joist. An open ceiling of course. The walls may be a problem but to fix it you may have to remove and re-do the roof or at least parts. The wall just may be out of plumb in certain places. You may possibly be able to "pull" the walls together with temporary cables and then re-do the joists and collar ties. The pieces you call purlins are not really necessary, they gave some extra support to the open joists. Adding extra (and heavier) rafters will also strengthen the roof while it straightens it out.....Mark Hammond
