Follow what the manufacturer says about the screws the type, size, and spacing. Check local codes too. Keep it sturdy and weatherproof. That’s how you pitch it right.

Wind Uplift Resistance Requirements

When putting screws on a metal roof, focus on the panel overlaps and put them on the raised ribs for stability. Secure screws along the edges, especially near the eaves and gable ends, to resist wind uplift. Make sure to fasten the screws into the support structure or purlins underneath. 

The manufacturer’s guidelines for the right screw types, sizes, and spacing. Avoid putting screws too close to each other to prevent metal stress. Also, consider the local weather extra screws may be needed in windy or snowy areas. Following these steps ensures a solid metal roof that can handle whatever weather comes its way.

Building Code Requirements

When putting up a metal roof, follow the building code rules. Screw placement matters. Stick screws on the panel overlaps and along the edges. Secure them in the purlins beneath. No screws in the flat spots between ribs, or water might sneak in. 

Each metal type may need a different screw pattern. Manufacturers give specs. Don’t crowd screws give them space. Check local codes, too. Wind and snow decide screw needs. Be wise get a pro if unsure.

Practices for Placing Screws on a Metal Roof
