I think this meteor came in a glancing angle and broke up at high altitude. If it were to come straight down it would have burnt up, or done a lot more damage. The terminal velocity of a baseball is ~95mph, a brick is ~150mph, so the meteorite must have been slowed down to around this speed before it hit the roof. It also would have had 4 min of freefall Canadian airblast to cool it off.
