Sheet Requirements
To calculate the number of sheets required to complete your roof, measure the width of the roof and divide this figure by the cover width -
ie: the roof is 3000mm wide, divide by 855mm = 3.5 sheets.

Round this figure up to the nearest full sheet - 4 sheets will be required.

Fixings Requirements
Divide the roof width by the fixing centres. Divide the roof length by the support centres and add 3.
Multiply these two values together.

= approximate number of fixings required.
