You can tap a punch on the top side of the panels, where you want the fasteners to go and the small indentation will make it easier to hold the screw in place while installing. Make sure to remove all screw shavings to prevent rust. - [Metal Roofing](https://help.gibraltarbuildingproducts.com/en/knowledge/metal-roofing?hsLang=en#main-content) - [Metal Roofing](https://help.gibraltarbuildingproducts.com/en/knowledge/metal-roofing?hsLang=en#metal-roofing) -
