Step 2: Calculate area of roof and number of tiles
First, calculate the area of the triangular part of the roof over the front bays. To do this, multiply the length D by E and then multiply by 2 if your conservatory has 3 bays or multiply by 3 if your roof has 5 bays.
D x E x 2 = X Triangular area of a 3 bay conservatory
D x E x 3 = X Triangular area of a 5 bay conservatory
Now to calculate the area of the remaining roof, which will be B multiplied by A, then multiplied by 2.
B x A x 2 = Y The area of the remaining part of the roof
You can then add the two area's together and times this number by 3 (as it's 3 tiles per square meter).
X + Y = Total square meterage x 3 = Total amount of tiles
As there is a lot of cutting involved we recommend adding another 5% to this number.
Total amount of tiles + 5% = Total amount of tiles required including wastage.
