Saw-tooth roof
![An example of the sawtooth form is this factory built for Morris Engines Ltd., at Gosford Street, Coventry in 1923.](/Images/godic/202502/09/Engines_branch5312.jpg")
A saw-tooth roof is a roof comprising a series of ridges with dual pitches either side. The steeper surfaces are glazed and face away from the equator to shield workers and machinery from direct sunlight. This sort of roof admits natural light into a deep plan building or factory.
