John Carter from Jay Carter Roofing Sheet Metal of Pefferlaw, Ontario writes, "The Siena Church roofing project, completed by Jay Carter Roofing & Sheetmetal , overcame numerous challenges to complete the installation of North America's largest diamond tile shingles roof at St. Catherine of Siena Church in Hamilton, ON. With an expansive 90,000 sq. ft. of roofing—significantly larger than the average 2,500 sq. ft. home roof—the scale alone presented major logistical and planning challenges. The project also required the use of complex equipment, including a 100ft manlift, necessitating careful coordination and strict safety measures. The custom 12x12 diamond tile shingles added another layer of complexity, as their specialized installation differed from standard roofing materials. Environmental and operational hazards, such as weather-related delays, further complicated the process. Despite these hurdles, Jay Carter Rofing & Sheet metal's team successfully installed the diamond tile shingles, along with a custom inlaid gutter system and TPO flat roofing. The project was completed on March 15, 2024, with Ira McDonald Construction Ltd. as the main contractor."
