Reusing old Trussess
Reusing old Trussess
(OP)
I've got a friend who wants me to certify that he can use wooden trusses he bought over a year ago to build his new house.
The trusses have been sitting outside the entire time with no cover on them.
They are still in tact but a few hair cracks about 4-5 inches long are noticed on the ends of the wood. This is in Bullhead city, Arizona.
Can he still use these trusses for his house, if so, what does he need to do to remidy the cracks at the wood edges.
Thanks

If they were new, then he should go back to the manufacturer for the certification as they would have certified the original design.
If they were used, with the horizontal end checking, I would be suspect of the any shear plate connection where the checking extended into the area of the shear plate. This is assuming that metal shear plate connectors were used.

Hope this gives you a better idea. He said they were bought new from the Manufacturer over a year ago and he does not want to pay the expensive fee for the manufacturer to recertify his trusses.
Appreciate your advice on this matter.

Why should you take responsiblity for free. If the truss later fails, you will get sued and lose your friend as well.
Tell your friend that you do not have insurance to cover your work.

It looks as if the water has not damaged them as they were stacked ok. sometimes there is lath in between for air circulation.
I wouldnt worry too much about the checking in the rafter tails. What we used to do to remedy deep checking in timbers is to use epoxy to seal them
