(A1) If there is danger of drainage dripping and freezing between the upper and lower units…
(A2) Then install a
roof
between the upper and lower units. Install the upper unit high enough above the lower unit to prevent ice buildup at the
upper unit's bottom plate.

(B2) Then it is not required to install a roof, but
