Darryl,
Just thinking.....wonder if the roof expansion along with the rail expansion 
are creating the issue....what kind of decking, roofing material is 
involved? It may be that the combination of the two might require a joint 
even though you haven't exceeded the 30' limit....just guessing.

Thanks I missed that, but my longest run is just under 30' I would think 
this requires an expansion joint at 20' or longer?
