Metal roof tops condo building

On Top Roofing used its New Tech Machinery rollformers to form metal roof panels on-site for Cache Condos in Park City, Utah.On Top Roofing used its New Tech Machinery rollformers to form metal roof panels on-site for Cache Condos in Park City, Utah. It installed more than 33,500 square feet of Drexel Metals Inc.'s 22-gauge Galvalume 1 3/4-inch snap-lock standing seam panels PVDF-painted in Medium Bronze over asphalt shingles.

The homeowner association board hired a consultant for the project because the new metal roof replaced a 7/8-inch corrugated metal roof with exposed fasteners installed five years before and was rusting in flashing areas and leaking in the laps where snow accumulated. The original roof on the condos was a cedar shake that lasted more than 20 years.

Jeremy Russell, of On Top Roofing, says the consultant insisted all the details be installed to specification. "That's what we do," he says. "In the five years they had that corrugated roof, they had more trouble with leaks than they did in 20 years with the shake roof."

Russell says they used a handgun application system from Hot Melt Technologies Inc. to inject the seams with butyl. Exposed fasteners were not permitted for the project, completed in November 2014. Stainless steel was utilized in many of the details including skylights, chimneys and roof-to-wall flashings. "We etched it, primed it and painted it with automotive paint to match," Russell says. "It took more time, but it will not leak." The new roof includes a watertight warranty from Drexel Metals.
