How heavy are the metal tiles?

What is the weight of steel tiles comparing with concrette tiles? This is one of the most common questions that we have to answer. The weight of the metal tile roofing sheets is about 3.5 - 3.8 KG per 1 sq.m. which is about the same as the weight of the ordinary corrugated iron. In the same time the weight of concrette roof tiles is about 40 - 50 KG per 1 sq.m. That means that with the same covered area you will have 10-12 times less weight on your roof. Not to mention that the concrete tiles can soak up some water and become heavier. Especially when the roof has been neglected for a while.

Due to this fact the conventional tiles will require a stronger (and therefore more expensive) frame. For example the roof trusses for a tiled roof will have to be set at 600 mm. In the same time the roof trusses for a metal tile roofing can be set at 900 mm. That gives you a 30% price reduction for your framing cost.

To me the choice is clear and it is for Metal tile roofing sheets.
