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 - i.e the roof is 3000mm wide divide by 855mm = 3.5 sheet. Round this figure up to the nearest full sheet - 4 sheets will be required.
Divide the roof width by the fixing centres, divide the roof length by the support centres and add 3. Multiply these two values together = the approximate number of fixing required.
