Rain will seep through the slope-wise join in the middle tile between its neighbours, between the lower end of the top tile and the upper end of the bottom tile. The lower end of the top tile must overlap the upper end of the bottom tile.
(I drew a diagramme of this to refresh my memory, so give it here if you want to go to the bother of working through it!) On the other hand, I think it is not obsessive to get things close ot what they are in reality, because that sort of detail makes a model convincing.
(If anyone lusts to know about undercloaking, feel free to ask, or not!)
A tip on slates (real slates): Coming from a place with slate rooves (Aberdeen), real slates have a nibbled edge all round. A give-away for artificial slates is they are cut cleanly.
Oh Oh! The tiles did not come out properly. Here is what they should have been:
