What kinds of damage does a tornado do to the environment and houses?

Environmental damage mainly consists of damaged or destroyed vegetation. Trees, which have a high profile, are particularly vulnerable.

Damage to houses varies considerably depending on how strong the tornado is and the construction of the house. At the low end, a weak tornado may only peel away some shingles and siding. At the high end, a violent tornado can completely obliterate a house, leaving an empty foundation. Tornadoes of intermediate strength may tear off roofs and collapse walls.
