Planning to raise the ceiling in the garage to make room for a golf simulator. Need advice and tips to see if this is feasible approximately as I have imagined.
The idea is that 3 out of 8 trusses need to be modified to raise the ceiling by about 40-50 cm to get a sufficiently large floor area with a higher ceiling height.
I haven't done any thorough measurements or sketches yet, just put together my concept before moving forward.
Trusses as they look now and how they might look afterward.
Sketch of the current garage with the placement of the trusses. There's a load-bearing wall at truss number 3.
A quick sketch of what I want to achieve, i.e., higher ceiling height with a sloped ceiling over a length of about 4 m located between trusses 3 and 7.
Hoping someone with experience can provide input on this project. The garage is 7.7m x 4.3m long. The roof has tiles, the slope not measured yet. Located in Uppsala, so there's a certain risk of snow in the winters.
Hoping for positive responses so one can soon swing away!
It is possible to do if you follow my ideas. Hope someone can confirm.
The collar tie you intend to remove is there to pull the walls together when the roof load wants to push the walls apart. Removing it will cause the roof to sink and the walls to lean outward. Drawn on iPhone. The gray is snow.
If you have trusses as you've drawn, the original rafters/top chords won't hold, and they will break.
Therefore, you must triple the rafters with a board on each side of the truss in the same dimension. Or add another rafter under the existing one. And a strong collar tie but placed higher up.
The first thing you should do is reinforce the wall plate to relieve the other trusses, see image, and modify one truss at a time, not all at once, or the roof might seize the opportunity to settle and say goodbye.
Then reinforce and rebuild one truss at a time. When there is no snow.
It will be stronger if you can build scissor trusses. Then you don't need to reinforce the rafters, just rebuild the collar tie with double strength. And attach new diagonals.
But you still need to reinforce the wall plate to relieve the other trusses.
The joints at the green arrows must be very strong.
Hi! Yes, I solved it according to my original sketches approximately. However, I reinforced all the modified trusses doubly with an exact copy in the same dimension against each truss. Didn't do anything to the wall plate. I got help and we concluded that the load-bearing wall holds together sufficiently at that point. It's a relatively small garage with low load on the roof. I've used it for a couple of years and it works great.

Hi. Do you have any pictures of the trusses before you installed the ceiling? ☺️
Bought a real screen for golf, so it was quite expensive. Used a coarse fishing net first but wanted a projector.
I think this is the one I bought:

Hi! Do you have any pictures of the roof trusses you set up for the golf studio? I'm having the same thoughts and considering increasing the ceiling height in the garage for the same purpose! What ceiling height did you get in the garage?/Mathias

Have been running it for a couple of years and it works great.
Feels like there are quite a few of us now interested in the same thing and images, I want to raise my ceiling from 205cm to at least 230 - 240cm in height However, due to a gym build.
