Hook Vs Nail

When considering your choice of slate, you should also consider the most suitable method of fixing.

Slate hooks offer a viable, perhaps even preferable choice over traditional nails in many situations.

Both fixing methods have their advantages and disadvantanges, as shown in the table below. Slatescape recommend the use of Hook fixing for our
Lovat Slates (Brazilian Grey-Green) and our Cinero Slates (Brazilian Graphite-Grey).

*Crimped hooks (which reduce the capillary rise of water at the perpendicular joints between slates) can be used to a minimum pitch of 25 degrees, straight hooks can be used to a
minimum pitch of 30 degrees. Always ensure you install to BS 5534 standards and guidance, and seek professional advice upon the suitability for your specific installation requirements
