On July 13, 2004, an F4 tornado demolished the Parsons Manufacturing Plant approximately 4 miles (6.4 km) west of downtown Roanoke. While over 200 people were still inside the plant at the time, the event was notable because there were no serious injuries or fatalities.
On April 17, 2013, after nearly 8 inches of rain in less than 24 hours, Roanoke experienced its worst flood in nearly 100 years. The flood waters reached parts of town it has never reached. Fehr's Welding shop had approximately 51" of water in it, causing Walt Fehr to make a new highwater hash mark in the building. Many families lost the entire contents of their homes and were displaced from their homes. The American Legion, who had recently built a flood wall that was 8 inches higher than any previous flood, was devastated when the flood waters breached the wall and crashed through the front doors destroying everything in its path. The Village Hall and both city buildings experienced significant flood damage. Village Hall had to be temporarily moved to Main St. across from the post office at Jenkins Automotive.
The water rose so fast from the banks of Panther creek that people had to be rescued from their homes by boat. The work of the fire and ambulance department undoubtedly save lives. The Lutheran church opened their doors and became a shelter for all of those needing a dry place to spend the next few nights. People from town provided dry clothes and blankets for the victims. On Saturday April 20, a clean up day was organized to help those in need. Approximately 350 volunteers arrived with rakes, shovels, wheelbarrows, tractors and trucks to begin the overwhelming clean up project. By the end of the day Roanoke looked like a different town.
