This seems like it should be simple, but I'm having trouble figuring anything out. Any way to make a slope that sits flush with this roof?

[u/Big-Stay2709]

I wanted to try something that looks sort of like a simple birdhouse, with a removable roof. This is just a test, the real building will have a bit more detail. The idea is the roof would just rest on the sloped parts of the front and back walls, with something on the underside of the roof to keep it kind of locked in without sliding forward or backward.

However, I'm not really sure how to make something that will actually sit flush with the roof. 1x2 45° slope bricks obviously have that stagger to them, which throws it off. Maybe there's a more technical method to achieve this?

I also thought about this plate roof, though it has the same issue, as well as a notch at the top. But if this would lead to an easier solution than the brick roof, I'm open to it.

This seems like it should be simple, but I'm having trouble figuring anything out. Appreciate any ideas!

The Italian Riviera set (21359) does this really well. Both flat sides of the roof are connected via technic hinge, anchored via pin along the same hinge allowing you to lift off the top or open either side independently.

Step 447, below, shows it coming together. Hope this helps!

Something hinged was my first thought. This is a nice solution

Looks like a nice evolution of the technique used in Ninjago City 70620, which also used inverted modified plates with pin holes to create a more textured roof: image

Extend the roofplate 1 stud all directions and add long 1×x plates on the underside outsides to make it gapless

Dropping the top layer would make it less noticable, or reduce the slopes, building out a facade or trim under the roof to hide the dips

LEGO sets with roofs like this hang the two sides of the roof on rotating technic pins, as someone else has shown. OR use any other hinge and clip elements. I'll take some photos of some when I get to my building station next. But essentially: build the roof as two pieces, and have them hinged in the middle, and lay them over the slanted wall pieces.

45 degree slopes are not 45 degrees when there are multiple. You can get it close and then hide the gap with a fascia tile on the ends of your roof or build a proper 45 degree slope that is possible but more complicated.

Yeah i was gping to suggest this. If you like the roof, change the wall.

[u/62Bricks → u/kon69nor]

Nice technique, but the OP needs a 45-degree slope. This is about 30 degrees

[u/clepewee]

If you want to keep to the 45 degree slope, another approach would be to build the gable triangle from plates and tiles attached sideways with brackets. Use the newish 45 degree tiles.

60 degrees can be made as a continuous smooth slope using cheese slopes attached to alternating headlight bricks and round snot bricks. Then an assembly of 3 hinges making an equilateral triangle as a basis for the roof.

Maybe something like little blue roof from B build (tournament) from castle creator set 3in1 number 31168

[u/RepresentativeOwn200]

Use hinged brackets

[u/Ka-Jin]

technic joints, studded pins, and plates?
