We are a Small Union Roofing Company offering roofing, waterproofing and coating services. If you can’t find what you’re looking for below, contact us to see if we can carry out the service that you are seeking.



GCI specializes in coating systems that will revitalize an old commercial flat roof and extend the life up to 20 years. There are many economic and environmental reasons to restore an old roof. By replacing an old roof the debris is sent to our landfill stations which are full and not very environmentally friendly. Tearing off the old roof is noisy, dirty and loud. It can be a large disruption to your business and not very welcoming to your customers.

High-Grade Coating systems allow no removal of the old roof, low odour compared to the smell of hot tar or high solvents. The economic savings of a coating system is ½ the price of a new roofing system, allowing you to save money and reinvest the savings to grow your business. A coating system is considered a maintenance item and can be a tax deduction, talk to your accountant about the savings.
