Flat roof construction that withstands large overhang?

[henkepenk]

What roof structures can be considered that can handle a roof overhang of 2 meters? Note the maximum building height of 2.5 meters (towards the entrance), hence it needs to be slender.

The reason for the roof overhang is that it's tight, I want to maximize the corner of the plot.

Some sort of steel beam I assume?

I would preferably like to lay a sedum roof or similar.

Is this feasible with a reasonable budget?

What kind of building is it, residential, garage, or?

You might know that roof overhangs over 0.5 meters are counted in the building area.
So it can become "expensive" centimeters.

Take a house that's 10 x 10 meters. Building area is 100 m2 if the roof overhang is 50 cm.
Increase the roof overhang to 100 cm and the building area suddenly becomes 144 m2.

Sorry, missed to mention that it is a carport! Yes, I was aware of this, thanks anyway.
I have 40 m2 denotation area on the plus land that I want to maximize.

Did a carport with an overhang happen? I'm also considering solving a substantial roof overhang with the help of a steel structure.

It turned out that way, but not with steel; it became beams in laminated wood with purlins across. https://www.byggahus.se/forum/threads/foerrad-och-carport-var-sommar-2017.291881/

What you need for a beam or solution completely depends on which snow zone you live in.

Gbg! Here it's just rain

Did you get a carport with an overhang? Also thinking about creating a large roof overhang using a steel structure.

Feel free to attach a sketch, maybe in a new thread Many eager designers in here

I'm thinking along the same lines and plan to make a large roof overhang with purchased trusses that I was considering extending with pieces myself (marked in blue) on one or both sides at the eaves. In my opinion, there should be about as much snow on X above the wall as X outside the wall. Therefore, the snow should balance each other in weight, and I assume the wall bears the load. Even though I'm in snow load zone 2, I thought it's good to go up to at least 2.5 since 100-year weather seems to come more often than every 100 years... so soon the 1000-year weather will be here. Any wind catch I thought would align with the concrete roof tiles I plan to use. If I nail 45*145 on both sides of the truss cc 120, marked in blue, how long can X be then? If I nail 45*170 on both sides of the truss cc 120, marked in blue, how long can X be then? If I nail 45*195 on both sides of the truss cc 120, marked in blue, how long can X be then? If I nail 45*220 on both sides of the truss cc 120, marked in blue, how long can X be then? If I nail 45*145 on one side of the truss cc 120, marked in blue, how long can X be then? If I nail 45*170 on one side of the truss cc 120, marked in blue, how long can X be then? If I nail 45*195 on one side of the truss cc 120, marked in blue, how long can X be then? If I nail 45*220 on one side of the truss cc 120, marked in blue, how long can X be then?

I think it's a bad idea and that you should instead talk to the truss manufacturer about a truss in the size you want.

I agree with xmlp3, ask the takstolstillverkaren, it will be much better and nicer.

0.5 meters........Oops, what a big house I suddenly got
