After a Hailstorm, Nineteen Office Buildings Are Restored During the Winter

Featuring 22 office buildings, fitness, conference and training centers, plus a hotel, the Denver West Office Park is an impressive complex. So, when it came time to re-roof 19 of the buildings with composite roofing tiles, it took two talented roofing crews to handle the project.

“Our crew re-roofed 14 of the buildings at Denver West,” says John Werpy, estimator/project manager for Arapahoe Roofing. “We had 85 installers on the project for four months straight. Access to the buildings, which are four stories tall, was a challenge. And, we could only load product on the weekends to minimize disturbing the tenants.”

The true challenges for Denver West began on May 8, 2017. That’s when a massive hailstorm caused extensive damage to the existing real cedar roofs on all of the structures. The National Weather Service reported hail that day ranging in sizes from golf balls to large eggs. One of the largest pieces of hail was recorded at 2.75 inches in diameter.

With the idea that the complex needed more durable roofing in case of future hail storms, the search was on. The result was the selection of resilient composite shake tiles from DaVinci Roofscapes. The Bellaforté Shake tiles chosen for the complex are Class 4 impact resistant and Class A fire rated. The tiles are also designed to resist high winds (up to 110 mph), curling, cracking, insects and algae.

Once the roofing system was selected, the clock was ticking. The property owners started the project in October 2017 and set a deadline of April 2018 for completion of the roofing. Arapahoe Roofing and Gen 3 Roofing were brought in to tackle the massive composite roofing project, which continued right through the bitterly cold winter months in Denver.

Winter Installation

“We immediately started removing the damaged cedar shake roofing, but then discovered asbestos felt problems in some buildings,” says Cameron Hummel, CEO of Gen 3 Roofing. “After dealing with those issues, we went on full-push to meet the deadline.”

“For our company, this project was very personal,” Hummel continues. “We’re a third-generation family of roofers and our family has been roofing the Denver West office complex since the 1970s, when they were first built. Just as our name implies, we’ve roofed these same buildings for three generations … in the 1980s, 1990s, early 2000s, and now again in 2017/2018. We’re proud that we accomplished our portion of the re-roofing project during the winter months ahead of schedule and without any injuries or safety violations.”

Winter weather was top-of-mind for the installers of the project. The first freeze in the Denver area arrived on October 10, making for a cold installation. Fortunately, DaVinci products are made of an engineered resin system designed so that tiles remain flexible for installation in colder weather. DaVinci composite tiles can be installed in temperatures as cold as 20 degrees.

“Our guys had many cold days of installation with this roofing project,” says Hummel. “However, we were able to keep on schedule because of the DaVinci products.”

When complete, the Denver West project had used 560,000 square feet of DaVinci composite shake tiles, 390,000 of them installed by Arapahoe Roofing.

“This was an ‘all hands on deck’ type of project,” says Werpy. “Re-roofing 14 structures in just a few months is intense. Our teams also re-lined the existing internal gutters and installed thousands of Rocky Mountain Snow Guards around the structures to help protect snow from avalanching down on cars and people below the roofline during winter months.”
