If you have a well insulated roof, they won't be able to detect any heat...
This is not true. Infrared detection CAN see through a roof. A metal roof is a bit harder, but normal fiberglass insulation is not going to prevent the choppers from picking up a hot attic. On the up side, they need a warrant to come looking. On the down side, I wonder if they follow the rules...
