   beef up the bottom chord of the adjacent trusses until you have load bearing members sufficient to carry the section across the headout?

   *Can you find out what the design strength of the existing trusses is? Depending on that nathan's idea would probably be the easiest answer.

   *Jim, Unless your going to use a super heavy roofing(tile, slate, etc.) the simple solution is to just run some purlins on 24" centers across the double space. Use the same size lumber as your top chord and start your layout so they will be under the seams in the roof deck. If you feel the need to, you can double up the members of the trusses after. Or you can consult your truss manufacturer. they may tell you that you need to double up with a second truss on either side of the larger opening. I hope this was helpful. Tony

   *Trusses 4' on center on a house ? Something doesn't sound right. Was one truss cut out ? Or were the trusses on each side doubled up ?

   we're framing a house and we need to fill in one rafter between two trusses to accomodate a stairway to a loft. The trusses are 48 inches apart and we need to put a rafter at 24 inches. The rafter has to be 26 feet long.
   Any suggestions on how to do this? PS. The only near bearing wall is under and parallel to one of the trusses.
   Thanks
