How the Calculator Works

To get the most accurate results, you will need to provide the exact building measurements and roof pitch.

Very Important Note: Before you order your metal roofing panels, you will need to get on the roof and physically measure its run, to the exact number of feet and inches. REMEMBER that the calculator provides only an APPROXIMATE length for your roof panels. If you do not measure the exact length of your roof run, your panels may come out too short or too long. If your panels are too short, they may be unusable. We are not responsible for the accuracy of any measurements on your part.

When measuring your metal roofing panels, always measure from the eave all the way up to the ridge line, and add at least 2 inches for drip edge and return lock.

Measuring your roof – you will need to use a tape measure to get the width and the length of your roof. You will also need to calculate your roof pitch, and properly identify your roof type. Use the following guides, which will help you to accurately measure your roof:

  • Roof measuring guide – learn how contractors measure and estimate roofs.
  • Roof Pitch guide – learn how to measure and calculate roof pitch. Roof Pitch multiplier table is provided at the end of this guide.
  • Roof Types – learn how to identify your roof type, and discover the difference between Gable, Hip, Mansard, Gambrel and Shed roofs.

Once you accurately measure your roof, plug in all the dimensions – the length, width, and pitch. Choose the width of your ridge cap – a typical ridge cap is 12″ total or 6″ on each side. The default setting for ridge cap is 6″.

Choose your roof type – gable or hip. While a gable roof is very simple, on a hip roof you will need to cut off the corners at the top of each panel, and also some panels will need to be cut in half to make shorter panels for the very ends of the hip roof. Also, on a hip roof you will need to pay extra attention not to make wrong cuts and not to waste panels. Otherwise, you may need to scrap the panels and get new ones.

Basically, use the old formula – measure seven times and cut once, when measuring and installing metal roofing panels. Refer to this excellent standing seam metal roof installation guide for more details on how to install standing seam panels.
