What nails are used on a slate roof?

By     Dec 15th, 2017
Most slate roofs use copper nails as they typically last longer than stainless steel and compatible with copper, lead and lead-coated copper flashings. A standard ¼” thick slate will require an 11 gauge nail where a thicker slate will require a 10 gauge copper nail.    The nails are available in smooth shank and ring shank.  Most roofers prefer smooth shank as it makes for easier repairs.
