This roof question is very popular and has been answered many different ways. Use the forum search for "organic roof".

Try OBJECTiVE.
Referring to the attached image, I made something like your roof by the following steps:
  • 1. Draw a cross-section through your roof with the fill tool and make a new Section object using OBJECTiVE > Component > New Profile

    2. Place the new object between the building extents

    3. Use OBJECTiVE > Tools > Bend to bend the roof to the building curve

    4. Place and open an elevation to view the new roof

    5. Use OBJECTiVE > Tools > Offset to raise the high point of the roof

    6. Use OBJECTiVE > Tools > Bend to shape the curve of the roof in elevation

    7. The result in 3D.
For clarity, OBJECTiVE is an ArchiCAD add-on, and is not free (unless you are working with an educational license). You can try it for 30 days free otherwise.

I have added "Mesh to Roof" add-on, and it works, but now I need to trim my walls to the roof, and with this roof trim function don't work properley.

I suppose the brown ramp is now made up of small slices of Roof objects.
You need to check the edges of two Roof objects to see that they form a Mitred joint. Those pieces of Walls not cut properly are a sign that the Roofs do not join properly.
Select two adjacent Roof elements withe the Roof Tool active then click their common edge and the small editing palette will come up where you can set how their edges are joined.

Yesterday I have already resolved my problem with this function (see image).
Despite this, thank you, laszlonagy.

Yes, that is very similar to what I suggested. Not perfectly accurate, if you zoom in very-very close, but as it seems it is good enough to make those parts disappear.
