The Horticulture Building at the Central States Fairground in Rapid City, S.D., is the centerpiece of the campus, recognizable thanks to the building’s distinct domed roof and unique history. The roof was originally atop a different Rapid City structure, the Alfalfa Palace, from the time that building was constructed in the early 1900s, but it was torn down in 1972 after a flood. City officials at that time recognized the distinction of the roof, saving it during demolition and moving it to the top of the Horticulture Building.
In 2019, a large hailstorm caused significant damage to the Horticulture Building’s roof, requiring a replacement. The chosen roofing solution needed to be able to provide long-lasting protection against varied weather conditions and conform to building irregularities, while also retaining the Horticulture Building’s original character. The contractor, Black Hills Exteriors, knew asphalt was the roofing solution for this project, selecting CertainTeed Carriage House® shingles.
