Estimate the Number of Screws for Your Metal Roof

Installing a metal roof requires a specific number of screws to ensure it is secure and weather-tight. This calculator helps you estimate the total quantity of screws you'll need, preventing mid-project trips to the hardware store.

How to Calculate Screws Needed

The calculation is based on industry-standard fastening patterns for metal roofing panels.

  • Roof Area (sq ft): Enter the total square footage of your roof. One 'square' of roofing equals 100 sq ft.
  • Screws Per Square: This is the estimated number of screws required for every 100 square feet of roofing. A common recommendation is 80 to 100 screws per square.

    • The calculator determines the total number of squares and multiplies it by the screws-per-square value to give you an estimated total screw count. It's always wise to purchase about 10% extra to account for any dropped or damaged screws during installation.
