I'm planning to build a roof over the patio and have decided to construct something using square tubes where I plan to stretch out a sailcloth, as shown in the image below.
The longest tube will be about 5 m long, and one of the attachments is, as seen, on the facade. Is there anyone here in the forum who has a sense of whether it will be reasonably stable if it's made with square tubes (40x40)?
Other ideas: The wind resistance can be significant. It should be possible to easily dismantle the roof during several days of bad weather or rain and when you are traveling away. Suitable slope and drainage are also sensible. Some form of manual hoisting mechanism on both sides isn't a bad idea... but it would certainly be easier with a wooden construction.
Sailcloth maker sewed my roofs which were difficult to roll in. However, they lasted for 8 years and in the last years, they were up from April to October. Right now I am trying to sew myself but with a simple hoisting construction.
I just stretched out a 4 m x 4 m sunshade as a patio roof with attachment points in the corners, and it became a far too large wind catcher, flutters nicely when it blows a little. I will rebuild it with 4 roof beams where the fabric will be attached so it can't flutter so much.
Thank you so much for the tips. I'll be welding on loops where I can attach blocks so I can easily "raise" the sail.
Follow-up question... Is there possibly anyone who knows where one can buy square tubing, suitable post shoes, etc. in the Stockholm area as a private individual?

Any other ideas or things I need to consider?
Thanks in advance

Found this old post. Was the dimension 40x40 good? How thick was the material? I'm going to make a similar pergola roof and am considering the dimensions of posts/beams (2.40m/4 m). Any tips to keep in mind? /Sofie

I think it seems a bit stingy, but it also depends on how exposed the sail becomes. I have posts 95x95 and no higher than 3 m, with under 3 m cross beams of the same size between posts. There are violent forces when the wind picks up—I only raise them in a full storm. But I live about 130 m from Ö-sjön.

I'm going to have a roof without a sail. Are your posts made of steel?

Ok - then I misunderstood you! No, I have a wooden frame construction that follows both long sides of the house. The original design was actually pressure-treated wood at 120x120(?), but it became very expensive, so we reduced the dimension. If you plan to have plants on the pergola, you need to consider the future weight, which can be quite significant.

Thanks for the tip! I plan to make it in steel, standing on an existing deck. I would like tips on suitable size/dimension for the steel material.
It's been a couple of years since I built this... so I should have the answer if it worked well... which it does. However, it's not exposed, but the construction feels like it holds up for the most part. Generally, I only take down the sail if we go away for a longer period of time.

Thanks for the pictures and response! Seems to have been useful for a lot!
