How to connect smaller roof to the bigger one?

I need to model a small roof that is attached to the bigger roof. VA cuts the bottom part of the smaller roof and I have no idea how to make it work. I guess that this should be exploded and modelled as normal solids but I would prefer to avoid that.

I would be grateful for a piece of advice on how to handle this situation.

The intersection of these two roofs can’t be edited, unfortunately. What you could do is to explode the roof into slabs (vaRoofExplode command) (you need to move the roof aside, so it doesn’t intersect with the other roof)

Thank you. That is what I did. After exploding it was nicely cut.
