Thatched roofs for kids
Most houses in ancient Europe, Asia, and Africa had thatched roofs. People have been thatching roofs since at least 10,000 BC, and maybe longer. Thatched roofs are hard to make, and you have to re-thatch them every few years or they will leak, but the materials are cheap and easy to get. You take dried grass or straw and make it into small bunches, and tie each bunch with a cord spun out of the same grass.

Then you line up the bunches next to each other around the bottom of the roof, and push them together tightly. You have to get the tension just right so that the bunches will hold each other together. Then you make another layer higher up, overlapping the first layer, and so on until you reach the peak of the roof.
Here's a video of a man in Ireland thatching a roof
Another problem of thatch roofs is that bugs and spiders and small animals like squirrels like to live in the roofs.
One advantage of a thatch roof is that it will gradually let the smoke out, if you have a fire inside your hut, so you don't need to build a chimney.
