FAQs
What size are the nails in this pack?
This pack includes 65mm galvanised ring shank nails.
Are these fixings suitable for metal frames?
No, these fixings are specifically designed for installation on timber structures.
How many fixings are included?
The pack contains 400 individual fixings, each consisting of a nail, washer, and waterproof cap.
Can I use these with Coroline green bitumen sheets?
While the fixings will function mechanically, the black colour-coded caps are designed to aesthetically match Coroline Black Bitumen Sheets. For green sheets, a different colour fixing may be preferable for a uniform look.
Do I need any special tools to install these?
A standard hammer is typically sufficient for installation. Ensure you have appropriate safety gear.
What is the purpose of the waterproof cap?
The waterproof cap seals the fixing point, preventing water from entering the nail hole and protecting the timber and the bitumen sheet from moisture damage and rot.
How should I space the fixings?
Refer to the official Coroline Bitumen Sheet installation guide for recommended fixing patterns and spacing, which vary based on roof pitch and expected wind loads.
Troubleshooting
Nail won't penetrate timber properly
Ensure the timber is not excessively hard or dense. Use a heavier hammer or consider pre-drilling a pilot hole if necessary, though this is generally not recommended for bitumen sheets.
Waterproof cap does not seal correctly
Check that the nail is driven flush and straight. Ensure no debris is obstructing the cap. The cap should press firmly onto the washer and sheet.
Bitumen sheet appears damaged around the fixing
The nail may have been over-driven, crushing the sheet. Ensure future fixings are driven only until the cap is flush. Significant damage may require the sheet to be replaced.
Fixings appear to be rusting
The galvanised coating is designed to prevent rust. If rust is observed early, it may indicate a faulty batch or damage to the coating. Ensure the fixings are fully seated and sealed by the cap.

Setup, Compatibility & Care
Setup:
- Ensure timber battens or purlins are clean and dry.
- Position the Coroline Bitumen Sheet according to manufacturer guidelines.

- Place a waterproof cap over the washer, ensuring it is correctly oriented.
- Using a hammer, drive the nail through the bitumen sheet, washer, and cap into the timber structure.
- Ensure the nail is driven straight and the cap sits flush, creating a secure seal without damaging the sheet.

Care:

- Inspect the roof periodically for any signs of damage to the sheets or fixings, though the robust design minimizes issues.
