Think about the grand cathedrals and churches in Europe. Most of them have impressive structures and are rich with history.
You can discover that same grandeur at St. John's Cathedral in Denver. The Episcopal church in Colorado was established in 1911 and is on both the National Historic Register and is designated as a Denver Historic Landmark.
This distinctive church now has new DaVinci Single-Width Slate roofs overhead. Yes, roofs. There are three distinctive buildings, so it was determined to use European - VariBlend on Roberts Hall to replace damaged slate and Canyon - VariBlend on the Parish Hall to replace older clay tiles. A Slate Gray - VariBlend was used on the main cathedral. The results are magnificent.
"In our bidding process DaVinci was presented as an option by all the bidding companies," says Judy Allison, director of facilities at St. John's Cathedral. "Frankly, we chose DaVinci polymer roofing because it was one of a very few products that were on a pre-approved materials list issued by the Denver Historic Landmark Preservation Commission. This commission must approve any exterior changes for a structure before a building permit can be issued."
The four-month installation process was completed by Horn Brothers Roofing in Denver, a company that has completed more than 80 DaVinci composite roofing projects in the past, including other churches.
"This was a massive undertaking," says Mark McMillan with Horn Brothers Roofing. "Because this is a historic landmark there are many requirements we had to meet. One of the biggest challenges came when we re-roofed the turret. We had to engineer a pie formulation for application to meet the requirements. This was an exacting process that assured the structure would still maintain its landmark status."
Now finished, the roofing on the historic church compound has an old world look with all the advances that science and technology have to offer. According to church members, the roof complements their building structures while providing protection from severe weather.
