Santa's landing place
I believe the answer is:
roof
'santa's landing place' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for roof that I've seen before include "Eg, mansard, gambrel" , "Mansard is an example of one" , "Protective covering on top" , "It could be slated" , "Housetop" .)
