1. A method for suppressing fire in a structure having at least one roof and at least one wall, the method comprising:
combining a foam chemical and water to form a foam solution;
introducing air into the foam solution;
forming a flame retardant foam by introducing the foam solution and air into an expansion chamber;
supplying the flame retardant foam to a roof plenum;
distributing the flame retardant foam onto an outer surface of the roof through an opening from the roof plenum to the roof, the opening being located at a ridge of the roof;
distributing the flame retardant foam onto an outer surface of the at least one wall through the opening from the roof plenum to the at least one wall; and
spreading the flame retardant foam laterally across a width of the outer surface of the at least one wall by flowing the foam downward over a distributor, the distributor comprising a plurality of static divider structures.
