I was planning to build a simple roof for the outdoor kitchen so you can stand under it in the rain, made a simple sketch. Between the front posts, it's about 3.8 m and the sides 2.5 m and I planned to use 95x95 posts. Does the construction seem okay or is there something I need to consider? If anyone has any tips on how to attach the beams to the posts in the best way, I would gladly appreciate it.
What dimensions are you planning to use for the joists in the ceiling? You need to consider the snow zone you live in to dimension the roof joists correctly.
As your solution looks right now, it's actually quite a long span with 3.8 m. What will happen is that everything will bend down, sagging in the middle if the timber is too thin. Additionally, if there's a lot of snow, there's a risk of breakage unless you intend to use sturdier dimensions. It's unfortunate to have an extra post in the middle, but it might be necessary to ensure the structure can handle a lot of snow.
To attach the joists to the posts, cut out the dimension of the joist at the top of the post (alternatively, you can reduce the cut-out by about 5mm on both sides so the joist protrudes these 5mm from the post, which looks a bit nicer). So, if you're using, for example, 45x145 timber, measure down 140mm from the top of the post and then cut away 40mm in depth. Then you just lay the joist in the groove that's formed and screw through the post and into the joist.
Thanks, I measured on my sketch which wasn't quite right, so it's actually a 3.3 m span and I'm in snow zone 3. I was thinking of using 45x145 joists. Do you mean something like this and then a carriage bolt through?

Yes, exactly like that. It will work great with a carriage bolt through, but it also works with a 6 or 8mm screw if you have one lying around. Whether 45x145 timber is the right dimension, I can't say for sure. It will probably hold up, but as mentioned, the risk is the deflection, although it will be at least smaller now if you only have a 3.3m span.
I've built a few roofs in the same style with the same dimensions you're considering, and they're doing well even today, 10+ years later. However, I'm in snow zone 2.
Anyone here on the forum want to calculate it perhaps?
Hello
I was absolutely sure I would build a roof, but changed my mind when I realized that I would often end up in the shade instead of in the sun.
But forget these negative thoughts because there are many good things about a roof too, you can pull out electricity, have a refrigerator, water, and the grill stays dry.
Yes, you should have some cross braces for stability.
Use carriage bolts that can be retightened.
Preferably choose something thicker than 95x95, as it will look flimsy.
Fun project, keep going and good luck.
