About Us

About Wilhelm Commercial Roofing Company

Our family has been in the roofing business since the mid-1920s. The company was founded by my grandfather, George W. Wilhelm around 1920 as a house painting business and it soon expanded into painting tin roofs and chicken coops, many of which still exist in the South Jersey area. George’s 3 sons continued the roofing trade into the early 1970’s.

My father, Vernon taught me the business right out of high school and over the years I have had the privilege of helping literally thousands of clients with their roofing problems and issues. Below is a small sampling of our past client list. It is my hope to add you as one of our many satisfied customers.
