Sawtooth

/ˈsɔːˌtuːθ/ adjective

Definition

Describing a roof profile with repeated triangular sections resembling saw teeth, typically featuring vertical glazing on one side to provide consistent north light for industrial or studio spaces while avoiding direct sunlight.

Etymology

Named for its resemblance to the serrated edge of a saw blade. This roof type developed during the Industrial Revolution to provide optimal lighting for textile mills and factories, where consistent illumination was crucial for detailed work.

Kelly Says

Sawtooth roofs solved the lighting challenge of the Industrial Age - how do you illuminate a huge factory floor evenly? By creating a roof that looks like a giant saw, early industrial architects captured consistent north light while avoiding the harsh shadows and glare that would come from skylights or south-facing windows.
