Hello Wrenches,<br><br>
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.<br><br>
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.<br><br>
Does this seem like a potential issue? Is there any data on
this?<br><br>
Thanks,<br><br>
Drake <br><br>
