Gambrel Roof And Salt Box Roof
Daughters of the mighty gabled roof mother
Both gambrel roofs and salt box roofs represent just the variation of the adorable gabled roof. Any of them looks like the traditional gable roof but shows certain differences.
Gambrel roof
The gambrel roof is the gabled roof with two slopes. The lower one is much steeper than the upper one.

The gambrel roofs got their name as in the past the gambrel roof design was usually used for barns.
Why gambrel roof design is so advantageous? Actually, itīs no brainer. Our grand fathers needed to put as much crops in their barns as possible. Therefor they invented the roof shape that allowed them to stock as much material under the roof as possible.
Gambrel roofs, more or less, have the same advantages and disadvantages as the gable roofs.
Gambrel roof offers the large ceiling space and still the front and the back of the roof (front and back gable) are just pure walls i.e. the masonry work that is not as lasting as the roofing materials (re-painting each 5 years, re-plastering from time to time also necessary).
Salt box roof
The slat box roof got its name as its shape reminds the shape of the salt box (surprised?).
The salt box roof is the traditional gable roof but it is eccentric as one of the roof surfaces is larger than the other one.

Salt box roof design is often used for the agricultural buildings but - of course - if this is your desired house roof design, you can ask your architect to design your own salt box house plans for you.
In my opinion, the saltbox roofed houses will always be popular in the future as their design is very simple and they offer better thermal insulation and water-proofing conditions and some (very limited) attic space compared to the
flat roofs.
