Slate roof survives F3 Tornado – Goderich Town Hall – 57 West Street, Goderich, Ontario
By Sheena Owen May 10th, 2018
A natural slate roof has many benefits when installed with non-corroding nails. In 2015, the National Slate Association tested slate for high winds. It passed the ASTM D3161-15 Class (highest) Wind Resistance Rating. Perhaps this is why the slate roof on the Goderich Town Hall survived the 2011 F3 tornado.
