How high is the roof of a house with a span of 5 meters?

1.25-1.7m. The height of the roof of a house is determined according to the span of the house and the different materials used for the roof. If it is a wooden tile house, the span is × 1/3= the height of the roof; If it is a color steel tile house, the span is × 1/4= roof height, and 5 * 1/3 = roof height. If the ridge of the roof is too high and the slope of the roof is too steep, the hanging tiles on the top of the floor are not easy to hang, and the tiles are easy to slide down due to gravity; If the ridge of the roof is too low and the slope of the roof is too small, the drainage of the roof will not be smooth when it rains in the future.
