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

We've done roof mount pv on tji's. 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.

I have also used the sunmoto mounts with the multiple holes. 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.

Hi All - We tie into TJIs commonly, if you Google "TJI solar" you'll find
manufacturer docs on how to properly lag in.

Dear Wrenches,
I have a customer with a low slope roof supported by TJI beams. 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.
Thank you,
Jerry Caldwell
