company-imageProper training is important to the correct installation of any roofing product, and International designs its training seminars to be the best in the industry. Experienced field technicians painstakingly instruct and guide training attendees — architects, roofing consultants, building owners and managers, authorized applicators, foremen, and our own employees — on the selection, preparation, and installation of International roofing materials. Actual “lab” time is planned for so each attendee gets the feel of using all International high-quality products.

The International Network

International Diamond Systems are marketed throughout the United States and Canada via a network of manufacturer’s representatives/distributors and authorized applicators, providing an immediate response to any customer need. These men and women are thoroughly trained in helping a customer properly evaluate the type of roofing system that will best suit their structure’s requirements, and then installing it. The International family is the best in the roofing business.
