Miller Outdoor Theater, Houston

Byrne Metals Corp. installed more than 18,000 square feet of McElroy Metal's 20-ounce copper 238T standing seam roof panels to re-roof Miller Outdoor Theater in Hermann Park, built in 1968.

Byrne Metals Corp. installed more than 18,000 square feet of McElroy Metal's 20-ounce copper 238T standing seam roof panels to re-roof Miller Outdoor Theater in Hermann Park, built in 1968. Canopy deficiencies caused leaks above the stage and audience.

Karl Schaack, PE, is president at Price Consulting Inc., the engineering firm for the project. "Everyone else who had tried to fix the problems focused on trying not to change the appearance," Schaack says. "We realized providing a leak-free solution required some change in the appearance. We got a little pushback at first, but when we explained our design, they were just happy to know it wasn't going to leak anymore."

The renovation included replacing the east and west wings, installing a soffit on the main sloped roof, framing the roof area between the existing steel super-structure with purlins, installing a metal deck on top of the purlins and installing a 1 1/2- inch nail base over the deck with an ice-and-water shield. A large, reverse-slope diverter was built at the intersection where the sloping roof connected to the stage wall. Additionally, valleys were lowered below the roof plane and there was a slight pitch change overcome by rounding the insulation and plywood over the pitch change.

McElroy Metal's rollformer was hoisted to the eaves on a scissor lift where panels were run onto the roof. Schaack says symmetrical metal roof panels are rigid and meet high-wind requirements. "The 238T is symmetrical so if a panel gets damaged, you only have to replace one panel," he says.

Byrne Metals began installation in November 2013 during the theater's off-season and the project was completed in 2014. Schaack says the copper helped the new roof blend in with the original framework. "Especially as it ages, it will look great, like it's been there all along," he says.
