Roof join issues

[houseplansource]

I can't seem to find help on this situation. I think I don't know how to word it so I will paste some screenshots below to show what I've done and how I did it. I'm not sure if I attempted this correctly or not, but I'm going to assume that I did not. That said, I have drawn a couple of roofs and attempted a join, but they will not join and clean up. I use Revit daily, but in a different industry so I don't ever draw roofs like this.

You can make them separately then join:

That's the problem. I don't really know roofs since I don't use them often. Thank you. I will look into some Revit roof videos.

If the roof slopes or geometry are causing the issue, especially in small roofing jobs, you might need to modify individual sub-elements of the roof (under "Modify" > "Sub-Element" tool) to ensure that they align better before attempting to join. If the roofs are supposed to meet at a wall or another architectural element, try using the “Attach Top/Base” tool to attach the roof to the walls first, as this can sometimes help clean up edges. If the roofs have different slopes or overhangs, Revit might struggle to create a clean join. Adjust the slope arrows or roof sketch lines to align them properly.

It sounds like your roofs aren’t joining because their sketch lines don’t fully intersect, the slopes or levels aren’t compatible, or constraints are preventing cleanup. Using the Join/Unjoin Roof tool can help, especially if you’re trying to prevent roof edge leaks. Ensure both roofs are compatible types and check that there are no gaps or locked dimensions. Adjust slopes or boundaries if needed, and the cleanup should work properly.
