Is anyone familiar with the Texaco "Matawan" style gas station building? It appears to be an all-aluminum structure that consists of nothing more than 40" wide flat wall panels with C-type sections on each edge. 40" wide roof panels are support on 5" double C-type rafters. A single welded girder (aluminum?) supports the center of the roof. There is not a single column or frame in the entire building. It was built in the 1960s.
A client needs to just re-roof one of these, but the inspector is concerned about the supporting structure and how some of the damaged composite roof panels can be replaced. I share those concerns.

Re: Texaco "Matawan" style building structure
You might try checking it out as a "cold form metal stud" system. It's also possible, even probable, that the thing is under designed. I've encountered several pre-engineered buildings (in Canada, of course) that were significantly under designed and which only survived because the building was never exposed to the code required loadings.
