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. Using 3" Asbestos profile sheet the roof is 3000mm wide, divide by the cover width which is 651mm = 4.61 sheets. Round this figure up to the nearest full sheet - 5 sheets will be required.

i.e. Using 6" Asbestos profile sheet the roof is 3000mm wide, divide by the cover width which is 1016mm = 2.95 sheets. Round this figure up to the nearest full sheet - 3 sheets will be required.
