Example
Tile quantity calculation
If your roof square meter area is 100sqm
Each square meter requires 2,2 tiles
Take the roof sqm of 100 X 2,2 tiles = 220 tiles
The Theoretical number of tiles required are 220 tiles
Add a tile cutting loss of 10% to the 220 tiles to allow for cutting loss during installation
10% additional tiles to allow for cutting loss = 22 tiles
The total number of tiles required for a 100sqm roof is: 220 + 22 = 242 tiles
You can thus order 242 tiles
