The roof estimation of damage could be calculated by your insurance company. I would contact them so they may send an adjustor who could better determine the exact amount of damage.
House Tornado was created in 1988.
No house can offer 100% protection from a tornado. The best option is a house with a basement to go to in case of a tornado.
The house is invading the tornado's natural habitat, so of course the tornado will fight to keep its territory.
The safest place to be in your house during a tornado is in the basement.
A tornado can hit a house, but cannot happen indoors.

Make sure that the tornado stays nonexistent.
It depends on how strong the tornado is. A sod house could probably survive a hit from a weak tornado, but probably nothing stronger than an EF1 or EF2.
The O'Leary house was spared.
Out of the ground, no. However, a strong enough tornado can wipe a house from its foundation. Normally this will earn a tornado a rating of EF4 or EF5, though if the house is poorly anchored an EF3 rating may be appropriate.
It depends on the severity of damage to the house as well as the value of the house. It is impossible to tell without seeing the actual damage; a professional estimate is needed for that. Most houses hit by an EF3 tornado will take less than EF3 damage. However, if the house has sustained EF3 or high-end EF2 damage the structure is probably a total loss.
Most likely not. Perhaps an EF0 tornado but nothing higher than that. But since tornado generally occur in warm weather the house would probably melt anyway.
