Roof Loading
Roof Loading
(OP)
I am checking the design of an existing roof system that is comprised of steel OWSJ, decking and roofing. The roof has to be designed to store an average depth of 4" of rain water.
Using the Ontario Building Code, we generally check a roof for 1.5x (snow plus factored rain). In this case, we are trying to decide if the roof needs to be checked for 1.5x (snow plus factored rain) plus 1.5x(retained water).
Any ideas?

Professionally, I would never do it where I live. But, I don't live everywhere. Cheers.
