Enter roof dimensions, then click Calculate Roof.

Standing seam roofing is a durable metal roofing system where panels are joined by raised seams (folds) that interlock, creating a watertight seal. It is suitable for roofs with slopes as low as 3 degrees [citation:1][citation:9]. The calculation of materials typically involves measuring the roof area, accounting for the slope, and determining the number of panels based on the panel width and length [citation:9]. Additional elements such as ridge caps, eaves, and fasteners are also required [citation:1]. This calculator provides a simplified estimate of the metal panels, fasteners, and approximate cost, helping with budgeting and material planning for a standing seam roof project.

1. Enter the Roof Width and Roof Length in meters.
2. Enter the Panel Width and Panel Length in meters.
3. Enter the Roof Slope in degrees (typically 3°–60°).
4. Optionally enter the Price per m² for cost estimation.
5. Click Calculate Roof to see the results.
6. The result shows panels needed, total area, estimated cost, and fasteners.
7. Click Reset to restore default example values.
