We ordered two different styles of trusses for our house. One half has scissor trusses for a vault ceiling and the other half has an open web style truss. We rented a telehandler and assembled a team to put them on the house.
Things went pretty well .... that weekend. However, three days later the wind knocked them down before we could get out there to give them extra bracing (day jobs always get in the way).
We were heartbroken. The next weekend we got to work taking them down and repairing any breaks. We attempted to put together a couple small sections fully sheathed so that when we put them up they would be stronger. Lifting them didn't go well, the lifting straps were plenty strong but one of the d-rings broke loose from the set of trusses dropping it. By the grace of God it only fell a couple feet and nothing was damaged and no one was hurt. After abandoning that plan, I texted a friend of ours who is a home builder to ask him if he has a roof crew. He replied with his guy's contact and said, "I let him know you will be calling." Good friends are irreplaceable!
I met with the roof guy and he gave us a very favorable bid. We hired him.
They did such a good job with the trusses and sheathing, that we hired them to do the steel as well!
The moral of the story is; trusses are doable IF you:
a) live in a non-windy area
b) can take off enough work to get them up, braced, and sheathed before the wind comes.
Up next windows and doors!!
