Natural slate has been the default Cornish pitched-roof material for centuries — and on the right plot it still is. Less than 0.4% water absorption, near-total frost resistance, and a life that comfortably exceeds a generation.
Brazilian, Spanish, Welsh — and Cornish
Most modern Cornish roofs are finished in Brazilian Grey Green or Spanish Del Carmen — affordable, beautiful, hook-fixable. Welsh and Cornish slate is reserved for heritage work and the most demanding planning conditions.
Hook-fixed for exposed pitches
On exposed Cornish coastal sites we hook-fix as standard — long-term holding strength against the wind uplift events that nail-fix struggles with after 15 years.
