Bill, Mineral bitumen roll roofing. 2:12 slope. Everyone who gave input below, thanks for the suggestions. I've decided to go with the Quick Mount Q-Base product. It allows you to get 2 lag bolts into the top chord on either side of the OSB web. Cheers,Jerry Caldwell

Our engineer required 4x blocking installed between the tji rafters that we lag bolted into. You're not allowed to cut or drill/bolt into the top and bottom cords of the tji's. We also packed out both sides of the tji plywood webbing prior to installing the blocking. Our snow loads oftentimes are too high and won't allow me to screw into the plywood roof deck only.

They are called the AL shoe I believe. It makes a great alternative to the DPW ez foot which are very expensive and take forever to receive. We but butal mastic tape on the back. Just like the ez foot.

Does anyone have experience permitting and installing on TJIs? I'm curious if jurisdictions are requiring Structural Engineer stamps. Since the top chord of the beams is only 1 3/8" thick should we be using shorter lag bolts for these installations? It also seems that it would be undesirable to penetrate into the web of the beam. Any advice would be appreciated here.
