Is it OK if the house's roof makes noise
Roof construction varies depending on where you live. In the north  you need to build to contend with a heavy snow load so roof trusses are more numerous and stronger. Sothern climes, not so much. Further, the roof cladding makes a difference. Many roofs in Europe are covered with tile or slate, which is heavy and needs the extra support. 

All buildings will creak and groan to some extent in the wind even steel high-rises. Though you may not notice in stronger buildings.

As for tornadoes.... If the roof blows off.. the drywall wont matter.

In some cases, wood frame is actually better than say brick. A wood frame house will creak and groan and bend, but except in the strongest wind, will not, if constructed correctly, catastrophically fail like a brick or cinder build building. In hurricane areas you will often find the timber frame buildings still standing surrounded by piles of rubble. Same goes for earthquake regions.

One more thing though. Creaking and growning is ok... Banging is not and is an indication that a roof panel has come away from its fastening and should be corrected immediately.
