Covers overhead (5)

I believe the answer is:

tiles

This clue is a double definition.

'covers' is the first definition.
(tiling is a kind of covering)

'overhead' is the second definition.
(thesaurus)

(Other definitions for tiles that I've seen before include "Small oblong slabs used in roofing" , "Roofing materials" , "Glazed rectangles used to cover walls or floors" , "Thin flat slabs of fired clay" , "Thin flat slabs, for roofing perhaps" .)

I've seen this clue in The Globe and Mail.
