Planning estimate only—not a panel cut list, wind design, or installation specification. This simple model assumes equal rectangular planes with full-length eave-to-ridge panels, one ridge when two or more planes are entered, eave trim on every plane, and rake trim on both sides of every plane. Verify net coverage, minimum slope, endlap policy, clips or exposed fasteners, fastening pattern and zones, substrate, underlayment, ventilation, closures, flashing, penetrations, valleys, hips, snow retention, thermal movement, corrosion compatibility, transport limits, manufacturer details, code, permits, and fall protection.

Transparent calculation

Sloped length first, then net panel coverage.

The pitch factor converts horizontal run to full panel length. Eave length is divided by manufacturer net coverage, and panels, fasteners, and trim are rounded independently.
