LEGO ROOF WITH CURVED SLOPES: This is a technique used in a number of official LEGO sets. The #10243 LEGO Creator Parisian Restaurant is one of the best examples. You can study the instruction manual for this set to learn how to use this technique. One important feature to notice is that the curved slopes are staggered to break up the smoothness of the surface and give it some texture. Otherwise the slopes are too smooth and would look unnatural. LEGO ROOF WITH PLATES: One of the easiest and most cost-effective way to build a roof is to just use two large plates in an A-frame shape, with studs facing out. You can add a few tiles, cheese slopes, or even some vegetation to make the surface more interesting. A good example is the #71006 LEGO Simpsons House. If you use the large plates with the tubes facing out, you can get a different texture for variety. An interesting technique is to insert yellow or tan minifig hands into the tubes for a straw roof effect as demonstrated by Geneva in the second picture below.

As you can see, there are many ways to make LEGO roofs, from simple to elaborate, pretty much being able to imitate all real-life roofing styles. The techniques mentioned above are well-established and have been successfully used by a number of LEGO fans. There are also many esoteric methods using pieces in clever ways that I haven’t covered here, and of course you can also experiment on your own. LEGO ROOF SUPPORT WITH LADDERS: This technique was shared by LEGO fan Adeel Zubair. It is used with standard LEGO roof pieces, which are quite sturdy on their own, but by adding one-piece staircases under the roof the structure gets additional support, plus the staircases mimic the look of rafters, as demonstrated on the picture below. If you plan to make the inside of an attic visible, this is a great solution. LEGO ROOF SHINGLES WITH MODIFIED SLOPES: This technique was shared by LEGO designer Mark Stafford, using some of the newish 2×2 modified slopes with cutouts. The final result is similar than what you can achieve with the 1×1 cheese-slopes. What do you think? Do you have any favorite LEGO roofing techniques from official LEGO sets or from other LEGO fans? Feel free to share and discuss in the comment section below! 😉 LEGO ROOF WITH GARAGE DOORS: This is quite an unusual technique used in the #70751 LEGO Ninjago Temple of Airjitzu. Because the garage door panels are flexible, you can create pretty much any round shape, by simple fixing the garage doors at the peak of the roof, and then draping them over the rest of the building.
