How should I view the splicing of roof beams?

The conditions are a felt roof on a shed where a wooden deck will also be built.

Beam size for roof beam and support beam: 45x220 C24
Possibly screw and glue together double 45x220 as support beams to increase the contact area for a potential beam splice.

The construction is:
9-meter span cc 60 with one or two support beams as extra support. Thus 2.83m or 4.25m free-standing depending on whether I choose one or two support beams.

Is a finger-jointed beam of 8.5m better, or is it better to splice beams on the support beams? If so, is end-to-end with nail plate or board applicable, or is it better to overlap splice the beams on the support beams?

Aesthetics are not important; I want to achieve the best strength.
 
Laskar, one on each side, approximately 1 meter long is usually a traditional solution. Plenty of nails from both sides.

Have you considered glu-lam? Especially for load-bearing beams..
 
Want to keep the ceiling height as low as possible.

What do you think about the dimensions in the frame?

And is it necessary to have 2 support beams or is one sufficient?

Anyone knowledgeable about strength is welcome to respond.
 
From what I understand, the size of the carrier beam and the density of posts under it are more important than the number of carrier beams, or am I wrong?
