Raytheon Technologies

           On-Top Industries Ltd. was entrusted to re-roof this 32,000 Ft2 facility in Calgary in 2023 with a mechanically Fastened 60 Mil GAF Thermal Poly Olefin (TPO) membrane over a recovery board. The existing hail damaged and failed Durolast PVC roof was removed and disposed.  Raytheon is a multinational aerospace and defense conglomerate with very stringent protocols and criteria for both safety and quality.  We are proud to be short listed and finally selected to complete this project safely, on time, and on budget.
