Just use the regular Solid Element Operation.
The four roof morphs are the target, the red one the operator.
Subtract then hide the red one in a hidden layer.
The advantage of this is you can move or edit the red morph and the hole will adjust to suit.
Subtracting one morph from another is a permanent (fixed) operation.
