Roof Design
Heat load calculations values :
W1 = 1.533
W2 = 2.212
W3 = 2.054
W4 = 1.841
all values are below 2.7 hence all the regions are valid to sustain the heat loads.

Snow Load calculations :
Q1 = 17.837
Q2 = 8.897
Q3 = 5.075
Q4 = infinity
all the values are above 3.1 hence all the regions are valid to sustain slow loads.
