I am remodeling a 1920 18" log cabin on the Minnesota/Canadian border. I am planning on putting on a metal roof this Spring, as it presently has shake shingles which are in poor condition. Starting with the wood planks and going towards the metal roof, what are the different layers that would provide good winter insulation and proper ventilation? There is no attic. Can I put the metal roof directly on the deteriorated shake shingles? Does your website have a cross-section diagram of what I need to do? Thanks from the "far-north"!

This is frequently done so, yes, it can be done.
I would suggest a quality underlayment beneath the metal roofing, a well ventilated attic beneath that and, if possible, a vapor (air) barrier beneath the insulation in the attic.
In all cases, make sure that the installation procedures are in keeping with those specified by the roofing manufacturer.

This website does not include those details because of the myriad of products and systems represented by this site.
One option is to choose some products you like and then contact their manufacturers for this kind of information.
Generally, I would suggest underlayment, vertical battens and then horizontal battens followed by the metal roofing. (Decking and underlayment could replace the horizontal battens.) The resulting airspace can be ventilated with soffit and ridge vents. This helps with heat control, ice damming, and moisture control.
