I have tried a lot of different ways to cover the Roof of my cube with a material, but every time I tried, blender covers the whole cube with the painting color. How can I simply coloring just parts of a cube?

To add a material to a specifc face (you can only assign and see material colors to faces), you first need to add a base material to your object, next enter Edit mode, select the face and then add a new material slot and create a new material or pick an already created one from the list and press Assign.

Select the desired faces and assign the material using 'assign' button in material panel.
