My first preference is to insert from the Block List.  "Move / Copy" seems to be okay.  Avoid Copy & Paste and importing drawing containing blocks.

Also, the origin of the block (0,0) is the insertion point for the block.  In the drawing provided earlier the shingles' origin were off to the far left and below the block itself.  If, for example, it was at the lower right corner of the shingle, it makes inserting the shingle block trivial.   With "Snap on end points" enabled, the next shingle can be placed to the previous shingle - almost like shingling a roof in the real world...
