Roof on the north and south slopes.

1, there is more rain in the south, and the slope of the roof is large, which is mainly beneficial to the smooth flow of rain and reduce its retention time and water accumulation; 45 degrees and 20 degrees tilt, its flowing water effect is different; There is relatively little rain in the north, so the slope does not need to be very large. Except for substandard quality and thatched houses, houses are generally snow-resistant. However, if it is a cover tile, if the snow melts, it will slide down. If the slope is large, it will drive or even bring down tiles when it snows, which is unsafe and is not conducive to shelter the house from the wind and rain. I hope it will help you;
