Greers Ferry High School, Greers Ferry, Ark.
The roofing crew installed 24-gauge Galvalume coil, formed to the DMC 200S profile with 18-inch striated pans. Hot butyl sealant was applied during forming.

“It was a fun one,” says Brian Kirk, who co-owns Freedom Roofing Solutions with his cousin Keith Williams. “We took off the existing roof and installed a metal roof.”
However, it wasn’t quite that simple. The original roof on Greers Ferry High School was comprised of asphalt shingles on a barrel-vaulted section and modified bitumen on some low-slope side roofs. During an attempt to economically patch leaking, “the school allowed someone to spray the roof with some kind of foam product,” Kirk says. “It looked pretty bad.”
Once the original roof was removed, Freedom Roofing Solutions added some structural framing to the low-slope side roofs to create enough slope—up to 1 1/2:12—for the new roof to more effectively shed snow and rain. Before the metal roofing was formed and installed, the crew installed a high-temperature underlayment.
Freedom Roofing Solutions, a Drexel Metals Association of Regional Manufacturers (DM-ARM) member, owns a certified Drexel Metals rollformer. After the panels for the barrel roof were manufactured, Freedom Roofing Solutions ran them through a curver, rented from Drexel Metals. Kirk says they built a “cradle” for the rollformer so it could be lifted to the eaves. From there, crews could run full-length panels with no laps all the way to the gymnasium, which was the barrel-vault section. Some panels measured up to 50-feet long. The entire project was approximately 26,000 square feet.
“We always manufacture panels with striations,” Kirk says. “Striations help mitigate the appearance of oil canning. We run the panels with pencil ribs and we’ve never had any problems.”
“Metal roofing was a great fit for this project,” adds Craig Boone, AIA, of Architecture Plus. “The barrel-vault roof over the gym with the two side sections … those panels on the barrel were curved onsite and laid down perfectly on the structure. From there, metal worked as a great transition to the two sloped side roofs. We were able to match the school colors and provide a leak-free roofing system.”
Boone notes within the first month of installation, the area received 20 inches of rain. “If it was going to leak, I think someone would have let us know by now,” he says.
