There is a sort of visible distinction between flat roofs and mansard roofs.
Mansard roof windows.
The dormer windows extend on the lower slopes of the mansard roof typically like the gambrel roof architecture which creates a habitable area often referred to as a garret.
For example they have the tendency to have dormers or windows that project out from the roof.
A mansard roof has a few other determining characteristics.
Mansard roofs typically have two slopes on each of its sides with the lower slope sitting at a deeper angle or even fluted with a curve.
The roofs feature two slopes on every side with the lower slope noticeably steeper than.
The lower portion is generally defined by dormer windows.
This design dates back to the 1600 s as baroque architects sought to create grand townhouses and chateaus designed to capture the eye.
Mansard is a four sided roof with double slopes on each side so its sides can either be curved or flat.
This structure gives you a traditional look and most commonly used in barn houses.
But you cannot misunderstand them as straight panel roofs.
It depends upon what type of design customer wants to implement.
The steep roof with windows creates an additional floor of habitable space a garret and reduces the overall height of the roof for a given number of habitable stories.
