Testimonials

  • Olympia Tile & Stone office and flagship showroom facility was covered with an aging and deteriorating roofing system, and the leaks had begun to disrupt daily business operations. Olympia needed an immediate fix. According to Guycan’s Roof Consultant “with a built-up system, we would have needed to postpone the project until spring when the snow and ice melts. Olympia Tile could not afford to wait because the current roof wouldn’t withstand another winter season. Leaks were already causing damage to their product inventory. Despite challenging weather conditions, including cold temperatures, high winds and record snowfall; Guycan was able to install the Duro-Last roofing system in 28 working days. Guycan has installed another Duro-Last roofing system at an Olympia showroom location in Ottawa (10,000 square feet) and are working on other locations for Olympia.

  • Kleen-Flo Tumbler Industries Limited had a roof that was over 30 years old, and needed constant repair to keep from leaking. Guycan’s repair service was able to contain the leaks, and keep the problem from worsening. Sukhdev Mann was so impressed by the prompt service; he decided to hire Guycan for the 85,000 sq.ft. re-roofing project. Guycan was able to install the Duro-Last membrane in 4 weeks with no disruption to Kleen-Flo’s daily operations. Sukhdev was impressed not only by the workmanship Guycan was providing, but also by the unique relationship he was able to build with Guycan owners Randy and Jason Deonarain. When it was time for Kleen-Flo to install solar panels, Guycan was the only solution.
