Our History

In 1980, Don Katzenberger was a hard-working, ambitious young man. Having worked as a roofer in high school, when Don graduated he and a partner decided to start their own roofing company - S&K Roofing. The pair's hard work, attention to detail and a focus on customer satisfaction quickly allowed them to add staff and contractors.

From 1980 to 2003, S&K Roofing had grown from a 2-person operation to a 20-person operation with revenue in excess of $8M. During that time period S&K also added services, including siding, windows, gutters and decks.

In 2001, S&K Roofing solidified their growing infrastructure and officially changed to S&K Roofing, Siding and Windows to better represent the company's expanding services. It was then, too, that they decided to adopt the tag line, "Worry Free. Guarantee."

In 2006, S&K moved to a brand new building and showroom in Eldersburg, Maryland (Carroll County).

In 2008, S&K won their first Angie's List Super Service Award, and has earned it each year since.

In 2009, S&K added blown-in attic insulation to their list of services to help their customers make their homes more energy efficient.

To date, S&K has worked on more than 100,000 projects. In 2019 we had our best year ever, solidifying our place as one of Maryland's largest roofing contractor.
