I used treated wood (2x6x10ft) for rafters for a patio cover. I had to halt construction for about a month. The plywood roof decking has not been installed yet. There is about a 2 1/2 foot overhang of the rafters past the beam. these 2 1/2 foot sections are warping /bending some. What is the best wat to straighten them. Thanks.. AgaPsdiver
It may not be possible. Treated wood is often bundled and shipped wet, so warping can occur. Premium treated stuff is selected with better stock (somewhat like quarter-sawed lumber) and will survive a natural drying cycle better. Picking out better boards at the box store may help. If the warpage you have is a real concern you might replace the rafters with common lumber since the treated wood is most useful for ground contact or bug resistance. Where you live will determine best course of action. Good luck.
