C'mon. I would think that a meteorite would have enough energy to go
through more than just the roof.

Not in that size, especially if it was ejected from a larger mass:

Collectors are also expected to begin combing the suburb for other
pieces which may have survived the molten descent.

Whence it may have been given an upwards kick on breaking up, slowing it
within more natural speeds rather than the initial interplanetary velocity.
Especially if it's rock... 1.3kg would be like 4" across.

and remember- velocity is relative. Earth is moving, as is the chunk
of space rock. if both are moving at about the same speed in about the
same direction it will have an impact speed about what gravity gives
it as it falls... still enough to bust through your roof.
