The original Mule-Hide trade name was registered in 1906. Mule-hide manufactured top-quality roofing products that quickly gained a reputation for long-lasting performance. The Mule-Hide® name developed because of an incident witnessed outside an office in Chicago. As the story goes, a horse drawn wagon with four horses was stuck in the mud. To help out, another driver hitched two more horses to the wagon. They were still unsuccessful. A short time later, a wagon with two mules came by. They took off all of the horses and hooked up the two mules. The mules dug down hard and pulled the wagon out. The impressive strength and durability of the mules would express those same qualities associated with the roofing materials Mule-Hide Products came to represent.
