Hi there! Checkout this Geometry Nodes based Roof Tiles Generator!
There are two Geometry Nodes.
One allows to create flat rectangular tiles on top of the roof surface. These tiles are fully procedural and give possibility to control a lot of different parameters.
Second GeoNode allows to use custom tile mesh, which means there is unlimited amount of roof styles possible to create with Roof Tiles Generator.
With next updates there will be added more roof presets and materials to the Asset Library. I would appreciate any help here: if you know which roof tiles are the very popular in your region - attach a photo here, would be very useful.
