Borrowed an image from the internet. I'm building a gable roof over the patio.
A few questions and wondering if any kind soul could shed some light on them.
I've done quite a bit of carpentry over the years, but never really thought about what everything is called in technical terms. Also, I've noticed when googling that "a beloved child has many names."
What do you call the load-bearing beam the arrow is pointing to? And also the ones sticking out from the wall at the same height?
And what height (underside) should it be set at if we might want to enclose the patio in the future? Is 200 cm too low? Or should there be more allowance? Initially, we were thinking of keeping it open. I'm considering standard frame dimensions. I want to avoid custom orders. A door also adds height from the floor, so I'm thinking 200 cm might be too low. Honestly, this is the toughest nut to crack.
How do you attach the roof rafters to the ridge beam if building like in the picture? Or is there an advantage to placing them on top? I want the construction height to be as low as possible but still have as much ceiling height as possible. Difficult to describe in text. Roof pitch will be about 22 degrees.
Cheers in the spring heat. Honestly sweating it out here.

I don't know if the highlighted beam has a specific name. Since the roof has a ridge beam, it's not really needed. The post that the ridge beam rests on could just as well go all the way up. The beams on the sides can be considered variants of a wall plate. However, the construction in the picture is not stable. Since there are no sidewalls, diagonals (preferably in the plane of the roof halves) are required so that the posts are fixed at the top.
The standard height for door openings is usually 210 cm. Since you will have glass partitions later, I recommend that you check the measurements of such on a manufacturer's website. For example, Willab gardens.

If it is fixed in the rear gable, it will be stabilized in depth. The front gable, on the other hand, is still not stable since the intention is for the roof to be a glass roof of some form. Diagonals are still needed. One is enough if it is placed horizontally from an inner corner to an outer corner. If they are laid in the plane of the roof, which will look better, at least two are needed.
I'm considering building a pergola with a gable roof. Can you explain what you mean by the diagonals? Please draw on the picture or on paper if you have time 🙏J justusandersson said:I don't know if the highlighted beam has a specific name. Since the roof has a ridge beam, it isn't really needed.

The standard measurement for free opening height for doors is usually 210 cm. Since you're planning to have glass sections later, I recommend checking the dimensions of such on a manufacturer's website. For example, Willab gardens.
