Wood, metal, rails, roof material, etc.

Not skid row.North Hollywood is not just gentrifying, it is getting densified, if that is a word.Big apartments going up and "SFR's" that are 6 inches apart with a metal critter barrier between units.

Maybe even make a little return from the metal frame.

The way his was designed, threre was a large rectangular "hot space" that went from the attic floor to the foundation, with a round metal "chimney" in the center, going up to the roof.  

Our green LEED architects reminds me constantly how we should go with metal roof or concrete material when we build.

That said, they get veeery hot in hot weather (it IS metal...), but I don't see any great disadvantages, as long as there are no zoning issues.

Zinsco electric panels had never been updated.Siding needs some minor repairs and full exterior paint job.Original 1942 Single pain metal windows need replacing throughout!

The makeshift solutions we find during demo are often entertaining, but sometimes just dangerous in terms of major property damage or bodily injury.

I am trying to do about 70% of the work, while subcontracting out for things like metal roof, solar panels, drywall finish, electrical, and ductless minisplit installation.  

If the frame is metal it is generally fine.
