Hello!

I know there are incredibly knowledgeable people here who might be able to give advice.

1.5-story house built in 1911, approximately 7.5x12.5 meters with a basement.

See the attached sketch (there are no blueprints of the house).
If the house lacks supporting legs for the trusses, is this something to be concerned about?

The plan is to replace the outer roof which is in its last days. Can I safely lay concrete? Considering the weight increase. Currently, there is clay tile. The outer walls consist of horizontal planks approximately 75mm thick, width varies between 2-300mm.
The top plate is 75x125 cc1200mm, collar beams are 70x145.
Measurements in the sketch in cm.
Snow load zone 2.5
Roof pitch 36 degrees if I calculated correctly?

Is more information needed?

Grateful for advice

Concrete and wet brick weigh about the same. But why change materials?
