Task 5: From the values recorded from the previous steps, calculate the flat roof snow load, 



. This snow

load is applicable only to a roof with a slope equal to or less than 5 degrees. The equation used to determine

this value is:

Flat roof snow load have minimum values, and are dependent on the value of the ground snow load. That is

if:
