Wind loads depend on wind speed and can vary as widely as the snow. 5 check for internal walls near the center of the house. The first kind of wall which carries the weight of the structure and supports the roof is known as a load bearing wall.

If there is another wall a floor with perpendicular joists or other heavy construction above it it is probably a load bearing wall. The roof trusses are too long to span the whole house so the load bearing wall runs down the center of the house to support the trusses at the perpendicular intersection in the middle.
