Fairbanks SBS had their roof collapse 2 years ago I think.
SBSs truss plant roof in Fairbanks failed in the 90a, pretty ironic.
The warehouse roof failed about 4 years ago, a portion of the roof collapsed on the main building about 2 years ago as you stated.
After the warehouse roof failed they "inspected" the roof on the main building. Apparently their X Ray vision was not working and they missed the wet foam. One would have to open it up to inspect that, musta thought it was a OK. LOL
Hard to see wet foam from the top side.
I think the truss plant roof failed due to a plugged roof drain. Big pond = point load.
Home trusses rarely fail.
