The vast majority of the jobs that we sell are fastened at 24” on center (O.C.). Therefore, we will base this answer upon 24” O.C. screw lines. If your screw lines are closer or further than 24” O.C. you can make some adjustments based upon this formula. We are also referring to these specific 36” wide panels: ⅞” Corrugated, R Panel or PBR Panel, and 7.2 Panel or Western Rib. Formula For Determining How Many Screws Will Be Needed Here are two easy formulas for determining the amount of metal roofing screws: Take your square footage and multiply it by 80%. Example: 3,000 square feet X 80% = 2,400 screws 80 screws for each roofing square. A roofing square is 100 square feet. Example: 30 roofing squares X 80 screws = 2,400 screws Do not forget to order metal to metal screws for the trim and panel sidelap You will need one lap screw for each lineal feet of trim or flashing Screw count for panel sidelap is determined by dividing the square footage by three and then dividing again by 1.5. Example: 3,000 square feet divided by three (width of panel) = 1,000 then divide that by 1.5 (spacing O.C. of sidelap screws) = 667 screws You don’t need metal to metal screws for the sidelap if using ⅞” Corrugated. You will only need sidelap screws for R Panel/PBR Panel and Western Rib/7.2 Panel.
