Can I use these screws for other roofing materials?

Troubleshooting

Screw head not flush with the roof sheet.

Check the screwdriver bit and ensure you're not over-tightening the screw. If necessary, adjust the torque on your screwdriver or use a manual screwdriver.

Screw stripping during installation.

Pre-drill holes in the timber subframe, especially in hard woods. Use a slower speed setting on your screwdriver to prevent stripping the screw head.

Water leakage around screw heads.

Ensure the integrated washer is properly seated and making a tight seal. Check that screws are not over-tightened, which can damage the washer. If leakage persists, apply a sealant around the screw head.

Setup, Compatibility & Care

To install these screws, you will need a Phillips head screwdriver. Ensure the timber subframe is suitable and that you are using the correct size screws for your bitumen roofing sheets. When installing, place the screw through the Onduline sheet, directly into the peak of the corrugation, and screw it into the timber subframe. Tighten the screw until the washer creates a firm seal. Avoid over-tightening to prevent damage to the sheet. Compatibility is limited to Onduline bitumen roof sheets, ridges, and end pieces. No special care is required beyond ensuring proper installation and regular inspections of your roof.
