Metal Roofing Panel Length Calculator

Gable Roof Panel Length Estimator

To use this panel length calculator enter whole numbers and decimals only. We plan to enable the use of fractions at a later time.

Enter the diameter of the roof ridge vent gap.

Finally, enter the coverage area (width) of the panels you plan to buy. For instance a 38" panel will have an effective coverage width of 36".

This calculates the distance from peak to trim so add length you want the roof metal to extend beyond the eave trim.
