How much of the mid-slope roof of a self-built house in rural areas usually floats out of the outside surface?

Generally speaking, it is twenty to sixty centimeters.

Generally, self-built houses in rural areas are not too high, that is, about two or three stories. The usual width of the eaves of self-built houses in rural areas of this height is about 30 centimeters. To be honest, 30 centimeters is a bit too high. It's too petty, and the rainproof and waterproof function can't be maximized. Personally, I think that the width of the eaves of a self-built rural house within three floors is 40 to 60 centimeters, because this width can keep out the rain, but it will not cause too much waste. Of course, if there are special decorative requirements, then there is another one. Something happened.

If the self-built house has a relatively high storey, it is still hoped to use overhangs to waterproof the exterior walls. In fact, the effect is not great. After all, the overhangs are just one overhangs and cannot be unlimited. Enlarge to the width you need. Of course, if it is four or five stories high, it will still be waterproof if the overhang can be 80 centimeters wide. However, in rural areas, self-built houses rarely have overhangs that are 80 centimeters wide. In this case Next, we can only do a good job of waterproofing the exterior walls. Of course, overhanging eaves still have to be done. Although the waterproof function is no longer strong, it still has a certain effect.
