One piece of concrete rooftile is 4.4 Kg (average) while the clay one weighed only 3.6. Kg. Of course, a 340 x 420 mm concrete rooftile will be heavier than a 30.5 x 30.5 clay rooftile! Now examine the weight of these two kind of rooftile in 1 m2. It takes 9.5 pieces of concrete rooftile to cover 1 m2; means totally 41.8 kg per m2. Compare with 16 peces of clay rooftile, totally 57.6 Kg. Now you know whih one is heavier.
