How to Use the Metal Roofing Calculator
Enter the dimensions for the width and length of your roof in meters, and the pitch of your roof in degrees into the respective fields. Once you have entered these values, click on the “Calculate” button to determine the area of your metal roofing in square meters. This area is the total surface that will be covered by the metal roofing material.
How It Calculates
The calculator first converts the pitch of the roof into a factor that represents how much longer the actual surface area of the roof is compared to if it were flat. Using trigonometry, the calculator determines the true length of the roof taking into account its pitch. It then multiplies the width by this corrected length to give you the total roof area.
Limitations
This calculator assumes a simple gable roof shape and does not account for irregularities or multiple roof sections. It is also not suitable for very steep pitches that approach vertical, as the calculation of the pitch factor does not hold in those extreme cases. Please consult with a professional for complex roof shapes or very steep pitches.
