I am not a structural engineer, nor would I second guess a structural
engineer's findings. The audacity here is that your inspector posture's
him/herself as knowing more than a licensed engineer and is imposing unfair
demands. Your maximum responsibility ends with an engineer's proj

With three rows and six lags in every other rafter there is a tremendous

tremendous force on each of the rafters. Unirac has excellent
information in their installation manual that shows all

Hi William,
Thanks for responding. We have three long rows of modules, with rails
attached every other rafter, every 4'. The inspector's argument is that two
attachments for one row might be fine, but that the wind load for the entire
