Does anyone know what the angle of a window sill should be? I assume if it's too level the water will not run off. Is there a standard or minimum angle a sill should be? Do building codes have a standard angle that's required?

Thanks! Mary

I personally know of no code requirements as to minimum angle of exterior sills, except as common sense dictates....that they should be less than 90 degrees to the window unit/panes and thereby allow any liquid water to run off and away from the unit.
