What Is a Saltbox Roof?

A saltbox roof is an asymmetrical gable where the ridge is offset toward the front of the building. The front slope is short and steep, while the back slope extends down to the first floor, creating a distinctive silhouette. Named after colonial-era salt containers.

Saltbox Area = Length × (Front Slope + Back Slope)
Ridge offset: typically 35% front, 65% back
Back pitch is shallower due to longer run

Advantages

  • Excellent wind resistance on the long back slope
  • Unique, historically charming appearance
  • Additional covered space under the long rear slope
