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.
