Over 40 years in business

Hello! I’m Don Katzenberger

Over 40 years ago in 1980, a partner and I started S&K Roofing. Our focus was on providing high quality workmanship to homeowners in Carroll and Howard Counties in Maryland. As a 2-man Maryland roofing contractor, we did well and quickly grew. We added other exterior home improvements, crews, and staff. Today we operate throughout Maryland and Northern Virginia.
