The areas you should be looking for cracks through which water might leak are the external walls and the ceiling.
Ceiling is more vulnerable to cracks as compared to walls.
You yourself can also have a visual examination of the roof, but if done by a qualified person its better.
Again depending on the type and depth of cracks, there are various types of materials available to repair them.
First i propose start with the inspection part.
