CASMA stands for Canadian Asphalt Shingle Manufacturers' Association, a corporation created on July 24th, 1989 pursuant to the Canada Corporation Act.

It was primarily established to serve and promote the best interests of all stakeholders in the Canadian asphalt shingle industry; namely manufacturers, consumers, suppliers, distributors and employees.

As well as being an advocate for the industry, CASMA has always sought to provide public and free education to the end users, i.e. homeowners. Please see our technical bulletins for more information.
