When calculating square footage of the roof area, should the pitch be considered? Or, are we still just calculating the footprint of the building? The building is only covering "x" number of square feet therefore what does pitch have to do with the impervious footprint?
Just wondering. The difference isn't that much.

The volume of rain falling cannot increase if all of it falls on pitched roofs.
So it must be the plan area that counts.
The effect of wind must be discounted - so the rain falls vertically down in the model.

I don't know why I even thought about it. I guess it's because if you calculate the number of shingles you'll need for a roof, you better not use the foundation plan to do it: You will come up short.

sounds like you're speaking from experience!
My brother and I put an addition on our office and we just kept buying materials and buying materials. I have a keen eye for red flags. Now I do.
