Hotel's leaking roof leads to replacement

Leaking gutters and a batten seam metal roofing system that was losing its paint made it necessary to replace roofing and gutters on Inn at The Colonnade Baltimore in Baltimore.Leaking gutters and a batten seam metal roofing system that was losing its paint made it necessary to replace roofing and gutters on Inn at The Colonnade Baltimore in Baltimore. Rick Wagner, RRC, CCS, vice president of Dedicated Roof and Hydro-Solutions LLC, provided consulting and inspection services during installation. "Issues with the leaking gutters was the impetus for making this project happen," Wagner says. "The apron for the gutters went quite a ways up under the roofing panels, roofing clips went through the apron, so to replace the gutters and that apron, the roofing pretty much had to come off."

Wagner provided a cost analysis to repaint the metal roof panels versus replacing them. He says the savings was nominal, mainly due to difficulty with safe roof access on the steep slope for painters. The roof slopes are 8:12 and 10:12, 125 feet above ground. "Once you take into consideration the new metal roofing system will long outlast the repainting, it was obvious that re-roofing was the best way to go," Wagner says.

Tecta America East LLC installed more than 27,000 square feet of Drexel Metals Inc.'s 22-gauge DMC 175 standing seam roofing with a Hemlock Green PVDF finish on the facility, which houses a hotel and condominiums. The panels have a 1 3/4-inch standing seam height and the color was selected for its similarity to the original panel color. Clip spacing was determined by the existing purlins; most were at 4 1/2 feet. Wood framing, covered by a peel-and-stick liner, housed stainless steel gutters, which required soldering in some places. Wagner says the gutter installation was all done by hand. "Nothing was prefabricated," he says.

Wagner says, as with all re-roofing projects, installers worked with imperfect framing. "There were places where the structural steel framing was not perfectly aligned," he says. "Installation crews did a nice job of working around that. It's a watertight system."

Steve Coyne, vice president at Tecta America East, says the installation was planned around the schedules of the hotel and condo board. "The biggest challenge was access," he says. "It's an occupied building, so we had to always be aware of events going on at the hotel. I'd estimate that half the time we were there was spent staging, erecting and taking down scaffolding, ensuring a safe installation." The project was completed in March 2015.
