Assuming the loss rate is 5%: ● Loss number = 734×0.05=36.7 tiles ● Actual total number of tiles = 734+36.7=770.7 tiles Therefore, considering other factors such as loss, a 100 square meter roof will eventually require 771 Roman clay tiles (0.15 square meters per tile).

Walking on a clay tile roof may be necessary, but it also carries certain risks. First, know that one wrong step can lead to cracked and damaged roof tiles. The smooth surface of clay tiles is particularly prone to becoming slick when wet, increasing the risk of slips and falls. Therefore, proper precautions must be taken before deciding to walk on a clay tile roof.
