Deck roof dimension

[depalma]

Hello!
I have a question, I know it's probably been discussed 2000 times, and I've read 1500 of the threads. But I still want confirmation that I'm thinking correctly.

I'm going to build a slanted roof for my patio (which will be glassed in). 4m deep and 6m wide.


I was planning to size the glulam as follows:

Posts 120x120
Bearer/front beam 90x225
Roof beam 56x225 (cc 120 roof beam)

Will this be sufficient, or do I need thicker materials? Snow load area 2.

Thank you in advance!

The wood guide, Swedish wood has a guide. It's awesome.

I have built a similar construction and I calculated that I needed support in the middle of the roof joists.
Mine is admittedly 5.4m deep.

Yes, I have looked at that construction.
Unfortunately, I can't have a support beam in the middle as it would end up in a glass section, so I would have to increase the dimensions instead.

Feel free to post some construction pictures when you start
