I'm in an even more unique situation living in a log house - there's not a whole lot I can do to the sides as far as insulation
If I can ever get my 100+ acres out in the wilderness, and build ANOTHER log cabin (which I DO love), it will be with MUCH thicker logs. Mine are fine for normal weather, but "abnormal" weather is when it gets tricky.
Plus, it wasn't built as a full time home - the original owner built it as a 2nd home/cabin. The roof is pitched with no attic. The only way to add insulation to the roof would be to re-roof. Though I have to admit that it must be pretty decent as there was no snow melting on it. When we lived in Marietta, WITH an attic, snow would melt almost the second it hit the roof, the house was so poorly insulated.
I have a heat pump, but if I decide to keep the house full time, I'll probably do what Wig has and have a propane central heater kick on when it hits below 34. I have an auxilary space heater downstairs that's propane and the propane gas logs, so that helps - especially a week ago when it was 30 and the electricity went out
It helps that I'm hot natured - I keep the thermostat around 60-62 any way
