I plan to lay 70 - 100mm of foam insulation on top of the roofing felt and mount counter battens and rafters on top of the insulation.
For the installation, long screws or nails are required, which should be stainless.
With both battens and the insulation, the length will be 120 - 150 mm before reaching the sheathing and rafters.
Does anyone have knowledge of or recommendations for screws or nails that would be suitable for this purpose, and where to find them?

Nail: 5 inches (125 mm) is a standard size
