FAQs

What size screws should I use?

The screws are 65mm in length and are suitable for use with Onduline's 2.6mm and 3mm bitumen roofing sheets. Always make sure the screw length suits the sheet and subframe thickness.

What type of screwdriver do I need?

A standard Phillips head screwdriver is required.

Are these screws rust-resistant?

The screws have a black finish. While this offers some protection, regular inspection for corrosion is advised, especially in harsh weather conditions.

How many screws come in a pack?

Each pack contains 100 screws.

Can I use these screws on any type of roofing?

No, these screws are specifically designed for use with Onduline bitumen corrugated sheets, ridges, and end pieces.

Do I need to pre-drill holes?

Pre-drilling is recommended, especially for hardwood subframes, to ease installation and prevent wood splitting.

What is the purpose of the integrated washer?

The integrated washer provides a tight, weatherproof seal to prevent water from penetrating around the screw head.

Troubleshooting

Screw head not flush with the roofing sheet.

Ensure you are using the correct screw length for the sheet thickness. Do not overtighten, and ensure the washer is creating a seal.

Difficulty driving the screw into the subframe.

Pre-drill pilot holes in the subframe, especially in dense wood types. Use a screwdriver with sufficient torque.

Water leakage around the screw head.

Ensure the washer is properly seated and making a tight seal. Check that the screw is not over-tightened, which can damage the washer.

Pros and Cons

Pros

Seamless Finish: The low-profile head blends in with the roofing for a sleek appearance.
Weatherproof Seal: Integrated washers create a tight seal, preventing water ingress.
Ease of Installation: Phillips head design allows for quick and easy installation with a standard screwdriver.
Strong and Secure: High resistance to wind uplift ensures the roof's durability.

Compatibility: Designed for use with Onduline bitumen corrugated sheets, ridges, and end pieces.

Cons

Specific Use: Designed specifically for Onduline bitumen roof sheets, not compatible with all roofing materials.
Screw Length: Requires selecting the correct length for the specific roofing sheet thickness and subframe.
Material: Screws are made of metal, which may rust or corrode over time if not properly maintained.
Installation Tool: Requires the use of a Phillips head screwdriver, which is not included.
Small Parts: Contains small parts, posing a potential hazard if swallowed.

Setup, Compatibility & Care

Setup:

Align the Onduline sheet, ridge, or end piece with the subframe.
Position the screw at the crown of the corrugation.
Use a Phillips head screwdriver to drive the screw into the subframe until the washer creates a tight seal. Be careful not to overtighten.

Compatibility:

The Onduline Universal Screws are designed to work with Onduline bitumen corrugated sheets, ridges, and end pieces. Ensure the screw length is appropriate for the thickness of the sheet and subframe. These screws are not intended for use with other roofing materials.

Care:

No specific maintenance is required. However, periodically inspect the screws for any signs of corrosion or damage, especially in areas exposed to the elements.
