1st Generation
Richard Nienke has 44+ Years Experience in the Residential Roofing field. It all started when he was 15 years old (1967); he started working with a Native American man cleaning up trash on his roofing projects. In 1968, the Native American started teaching him the basics of shingling. In 1969, he started chasing storms with the Native American. In 1970 at the age of 18 he started chasing storms on his own and continued working storms in the Midwest until the 1994-1995 hailstorm brought him to Dubuque, Iowa. Through the years of chasing storms he realized how many roofers were just there to get a check. In 2000 he opened Roofco Home Improvement specializing in exterior home improvements. It was in 2004 that he was able to turn his focus to Residential Roofing only; it was then that the name was changed to ROOFCO Residential Roofing to better suit the focus of the business. In 2008 received it's first customer service reportabout ROOFCO Residential Roofing. Then in 2009 ROOFCO Residential Roofing joined the Dubuque area Chamber of Commerce.

In May of 2012 ROOFCO Residential Roofing was the 1st TAMKO Pro Certified Contractor in the State of Iowa.
