Jason,<div>In my experience with a roof like that there were purlins running horizontal to the trusses, so spacing L-feet to miss the ribs was not an issue. Unless you have visually confirmed the truss location it might be worth a more detailed look to see if there are purlins you can attach to.<div><br></div><div>This might be an option for waterproofing the penetrations... <a href="http://www.eternabond.com/DoubleStick-p/cr-ds.htm">
