It is important to drive or install the screws correctly. This is a really simple procedure, but quite often it is done incorrectly. If you mess this up your roof will leak, so taking the time to correctly fasten the screws is exceptionally important. This video will be an excellent guide that will clearly demonstrate the correct way to tighten a screw.

The screws that you will be using will have a rubber washer with a metal cap. The rubber washer is just a bit smaller than the metal cap. You want to tighten the washer so that it spreads to the edge of the metal cap and not past the metal cap. When you tighten the screw it’s critical that you don’t drive it too far.

It’s a natural reaction to exert too much pressure and tighten the screw as much as possible. This will over compress the washer by expanding it too much and breaking the washer. If this happens back out the screw to relieve some of the pressure. If you over-tighten the screws then they might leak and will also need maintenance sooner.

Conversely, it is common to under-tighten the screw. The easiest way to determine if the screw is too loose is to see if you can spin the washer. If the washer spins, then the screw is too loose and should be retightened. You will develop a feel for fastening the metal panels correctly, but just pay close attention to ensure that the screws are installed correctly.

Screws Should Be Installed Straight And Not Sideways

Screws that are installed sideways or tilted will not permit the rubber washer to seal correctly. This will create a possible leak point. If you notice this has happened then back the screw out and redo so that the screw is straight.
