Saging rafters
#1

This is in referance to the ? from JSG ,( A dip or sag in the roof) answered by Twelve Pole & Jack the contractor.
I have the same problem and you have answered what i needed to know but i have one more little? in sistering a rafter must you use the same size?? say 2X6 or 8 or can you just use 2X4s?? Or is it a case that they would not be strong enough? Also in lineing up the new sisters should you run string line both top and bottem, peak and eves or is there a more accurate way of makeing sure they are level?? Thanks for your help

You do not use anything less then a 2x6 when sistering. You asked about a string line from top to bottom. I run the string line across the roof instead, this makes your roof level. Up and down may cause you some grief. Run the line across the lowest point.

Thanks for the info and that was what i was trying to say. A string line across the roof both at the top of the roof and bottom. But i will do as you say and try it at the lowest point. Also do i take the sister rafter all the way out to the end of the eves ? or do i stop at the outside edge of the top plate? again thanks. cliffhanger45
