THE FACTS ABOUT DURO-LAST SINGLE-PLY ROOFING
Great Lakes Roofing and Insulation Systems specializes in the installation and maintenance of Duro-Last Roofing Systems. For over 40 years Duro-Last has led the industry in PVC membrane roofing and Great Lakes Roofing and Insulation Systems has been a part of that success for more than 35 years.
We are proud to be a Duro-Last Platinum Contractor. With each commercial roof installation, Duro-Last sends a Quality Assurance Technician to inspect the completed project. The QA then grades the installation. Last year, we installed more than 500,000 square feet of roofing and earned an average grade of 95%.
As our customer, you benefit from the family-type relationship we have developed with the manufacturer. We work together to bring you a superior product with the best installation to deliver the best roof!
