The Footing Uplift Sizing Calculator estimates the size of a concrete footer, based on a 100 ft 2 tributary roof area.  
The pressures used by this calculator are determined assuming zones 2/2E for a 10ft max mean roof height and  a 1/12 max roof slope.  Pressures used by this calculator do not apply to partially enclosed structures.
