[RE-wrenches] Lags & Trusses

[Drake Chamberlin]

Hello Wrenches,

I just talked to a carpenter, who we are installing an array for.  He 
is putting a new roof on the building and was talking to the 
manufacturer of the trusses.  He mentioned that he was having an 
array installed on the roof.

The truss manufacturer said there were problems with weakening the 
truss structure with the lag screw penetrations.  We are now planning 
to sister boards next to his trusses instead of penetrating them.

Does this seem like a potential issue?  Is there any data on this?

Thanks,

Drake
