I have plans to connect the garage with the house. The garage is currently detached. For simplicity, I was thinking of building a shed roof for the garage (extending the house's gable roof is not an option).
Attached is a picture of how I'm thinking. I'm aware that it will be a bit tricky where the garage roof meets the house's gable roof, but it can surely be resolved.
As sketched above, I was planning to place 45x145 beams (the green ones) along the house wall at cc 1200mm.
Place a 45x145mm supporting beam (the red one) on top of the green beams along the entire wall.
Then I planned to place 56x225mm glue-laminated beams (the blue ones) at cc 600mm.
I have no clue about dimensioning when it comes to these things, but could this work?
The span for the blue glue-laminated beams will be about 4.6 meters.
This is for snow zone 2.5 and I'm thinking about a roof pitch of maybe 8 degrees and roofing felt.
A metal roof might be relevant in the future, but initially, it will be felt.
If you are going to have an insulated roof, then 56x225 is on the weaker side. If you want to keep the same width, choose 56x270 instead. Otherwise, there are many other combinations that are possible.
Yes, I definitely intended to insulate the roof as well as possible while I'm at it.
Are the bearing beam and the vertical studs sized at 45x145 sufficient, or do you need thicker ones there as well?
But 56x270 should be sufficient to withstand the load?
45x145 C 24 is sufficient for both posts and the innermost beam. There are alternatives to 56x270 depending on whether you want to prioritize price or low beam height. For example, 42x315 or 190x180. However, 56x270 is quite a good compromise.
It will most likely be 56x270, but it's good to know that there are other options.
42x315 might not be a bad idea either, as you should reasonably be able to fit in more insulation.
I have plans to connect the garage with the house. Currently, the garage is standalone.
For simplicity's sake, I thought of building a shed roof for the garage (extending the house's gable roof is not an option).
Attached is a picture of what I have in mind. I'm aware it might be a bit tricky where the garage roof meets the house's gable roof, but it can probably be solved.

As I've sketched above, I was thinking of installing 45x145 joists (the green ones), along the house's wall at 1200mm centers.
Laying a 45x145mm load-bearing beam (the red one) on top of the green joists along the entire wall.
After that, I was planning to place 56x225mm glue-laminated beams (the blue ones) at 600mm centers.
I have zero knowledge about sizing when it comes to this kind of thing, but do you think this could work?
The span for the blue glue-laminated beams will be about 4.6 meters.
Applies to snow zone 2.5 and I’m thinking a roof pitch of maybe 8 degrees along with roofing felt.
Maybe a metal roof might be considered in the future, but initially, it will be felt.
Many thanks!

Hello,
How did it turn out in the end?
I'm almost thinking the same way (building a garage connected with the house, roofing felt, shed roof, etc...). How thick is the insulation?
Is the interior ceiling flat?

If you are going to have an insulated roof, then 56x225 is on the slender side. If you want the same width, choose 56x270 instead. Otherwise, there are many other combinations possible.
56x270 is no problem according to my calculations for Glulam GL 24h, snow load 2.5kN/m2, self-weight of roof with insulation and metal 0.4kN/m2, and safety class 3. Assumed simply supported. This gives an utilization rate of 80%, the other checks for compressive strength, shear, and deflection control result in much lower utilization rates.

For simplicity's sake, I plan to build a sloped roof for the garage (extending the house's gable roof is not an option).
I'm attaching a picture of what I have in mind. I am aware that it will be a bit tricky where the garage roof meets the house's gable roof, but it can surely be resolved.

As I’ve sketched above, I planned to set 45x145 joists (the green ones) along the wall of the house at cc 1200mm.
Place a 45x145mm bearer (the red one) on top of the green joists along the entire wall.
Then I planned to lay 56x225mm laminated beams (the blue ones) at cc 600mm.
I have no clue about sizing when it comes to things like this, but could this work?
The span for the blue laminated beams will be about 4.6 meters.
It applies to snow zone 2.5, and I envision a roof pitch of about 8 degrees with roofing felt.
Perhaps a metal roof will be relevant in the future, but at first, it will be felt.
Many thanks!
Best regards, /O
Hi, how did the solution where the gable roof met the garage roof turn out? I'm having the same thoughts here at home…
