1915 – 1954 Bernard was followed into the roofing business by his son-in-law, Mark A. Cronin Sr., a founder and early president of the National Roofing Contractors Association. Mark expanded Knickerbocker’s services to roofing railroad structures and replacing roofs for some of the largest corporations throughout the Midwest.
1954 – 1982 The three sons of Mark Cronin – Jim, Bob and Mark Jr. – all graduates of the University of Notre Dame, continued to expand the services of Knickerbocker with large contracts from the steel industry, utilities and major corporations. Our services were extended throughout the Midwest.
1982 – 2014 The fourth generation of Knickerbocker owners included four great-grandsons of Bernard Kelly, each with many years of experience. All these men were (and still are) substantial stockholders in the company, and thus had a significant investment in the quality of Knickerbocker work and the reliability of Knickerbocker service.
2014 – Present Today, Knickerbocker Roofing continues as a company of substance. Due to our firm’s outstanding stability, we have an established line of credit and strong bonding capability. We are one of the largest roofing contractors in the Midwest. We are also a company of tradition – a tradition of workmanship and service. We would like to extend that tradition to you, and welcome this opportunity to share our Knickerbocker history with you.
