The modern pitched roof houses also use the same concept.
Golden ratio roof pitch.
These architects use the golden ratio or a roof pitch with a ratio of about 1 1 62 as a benchmark to test their intuition on an unsatisfactorily designed roof.
It is present everywhere and has been historically used by planners across history including the construction of the great pyramids the taj mahal the parthenon and so on.
In simple words a golden ratio provides a sense of equilibrium and balance to the construction.
This led taylor to claim that in the great pyramid the golden ratio is represented by the ratio of the length of the face the slope height inclined at an angle θ to the ground to half the length of the side of the square base equivalent to the secant of the angle θ.
Designers are often asked to reduce the pitch of a roof by planners because it is considered to have too great an impact on the adjacent buildings.

Look diagonally top left to bottom right for square pieces and horizontally at rows or vertically.
The golden ratio without going into the minutiae that are drilled into all students at architectural school the golden ratio a ratio of about 1 1 62 simply acts as a benchmark against which any architect that finds a design unsatisfactory can test his intuition.
A ratio of 1 1 62 is known as the golden ratio and therefore the vast majority of roof pitch in degrees charts you see will be working to this ratio at the very least.
Which means that once you ve found the right ridge height for a given footprint the roof pitch is the only remaining variable.
Therefore whenever architects have a difficult time deciding the pitch of a roof they refer to the ratio as a reference.
