To get started, let us know the actual size of your roof (not the size of the membrane required). Enter your measurements either in Metric or Imperial.
Please enter the “EXACT Roof Size”, not the membrane size. Our calculator will automatically calculate the membrane required based on your roof size. It will also provide you the ability to tailor the membrane size further in Step 3 if so required.
The ClassicBond calculator will only calculate roofs that are square or rectangular in shape.
For L-shaped or other roof designs please break the roof down into square or rectangular shapes and combine the material quotes.
