Metal Siding and Weather related issues

I think most areas have guidelines as to how much exposed foundation needs to be there. I would never advise siding to go to grade. Should there be any porous material behind it, it could cause a "wicking" situation & pull moisture up behind the siding. Plus there's always chances of damage to it from snow removal equipment, de-icer, etc. Just my 2 cents.

I would agree and yet I see so many new homes that have siding about 6" above grade.  Here in the Pittsburgh region we often get snow that makes it up to 12" and then there is drifting.  I haven't found any codes that restrict placement above grade.

The north side of my house will have snow and ice a foot or so up against it much of the winter.

 

New construction requires siding to be 8" above the earth.

 

In areas prone to termites, an exposed foundation makes their tunnels easy to spot.

 

There are many, many metal buildings where the siding runs to concrete or asphalt. The slab is raised an inch or so forming a rabbit for the siding to sit on.
