Salt Box Roof
A saltbox is a building with a long, pitched roof that slopes down to the back. A saltbox has one story in the back and two stories in the front.
The asymmetry of the unequal sides and the long, low rear roof line are the most distinctive features of a saltbox.
It takes its name from its resemblance to a wooden lidded box in which salt was once kept.Slide10Slide11
A flat roof is a type of covering for a building. In contrast to the more sloped form of roof, a flat roof is horizontal or nearly horizontal.
