I often find that roofs cannot be joined, like in the image below.
First of all, why can't they be joined. Second if they can't be joined, what is the best way to create a roof opening?
Vertical opening tool?
Are you using the Roof Join tool? If so, it's probably because part of the roof is missing the target.
Post the File.
...in answer to your second question, you could do both roofs with one sketch boundary/one roof.

I have attached the file. Can't join the gable to the right side of house...
yes.. did you do it with roof join or vertical opening?
Vertical opening makes my attic plan cut perimeter look strange so I'd really like to be able to
do roof join and I don't know why I can do it sometime but not others...
I did it quickly by cutting the roof with an In-Place Modeled Void and then use the Opening by Face tool to created the opening in the roof.
Ahh,
I can't do in place void (I'm on Revit LT)
check out the second floor plan, do it look strange at the cut line?
Any luck with roof join?
If you can't do an In-Place Modeled Void, then Model the Void in a Family, check "Cuts With Void When Loaded", and then load it into the Project and use Cut Geometry to cut the Roof with the Void Family.
FWIW, I don't see anything strange in the Second Floor Plan.
You could do the two roofs as one roof, as I mentioned before.
Using Slope Arrows to define the 7:12 Roof in the same Sketch as the 12:12:
...and overhang done as a separate Roof via Roof by Extrusion.
Hi you can't join the roof because the thickness of the both roofs overlap
You can try this change the rafter cut to 0 and move the roof till the red line

Maybe the walls wont attatch to the roof but edit the profile of the walls and it's done. Well i don't know if the edit profile is available in LT if not you have to do some modifications for those walls.
Have a good day!

That's exactly what I did in message 10 screenshot. Look at the sketch boundary. See the teeny tiny Define Slope Symbols?
I did mean like this. then join the roofs.
For me works I don't know if its a bug on LT

Oh, you think it's an issue the OP is having because he's on LT. Yah, I'm having no issues with any approach on Full Revit. Roof joins fine, no matter what its sketch boundary longitudinal extents are. I don't know why LT won't cooperate. Seems pretty basic stuff.
Yeah maybe, we are working in the same model and works in different ways also available in LT, But It's pretty strange because Svalen had anothers roof joins into the project without problems. Only left delete that roof and create a new one.
