    Derek Kasten

    President

    Derek started at a young age in the family business.  He loaded materials at the warehouse his first two summers during middle school.  Soon after, he was working on the roof with crews for both steep slope and flat roofs.  He gained first hand experience from peers in BUR, EPDM, PVC and Standing Seam roofing. 

    After Derek graduated high school, he attended WTC and graduated with a degree in Computer Office Specialist.  Quickly, he 

    implemented those skills to improve bidding efficiency for the company and started his career as an estimator.  

    Derek married his high school sweetheart soon after gaining his degree.  Together they have 5 beautiful children together.  

    After 50 incredible years in the roofing industry, Derek's father Charlie completed a succession plan with Derek and his brother in law Jon Kloehn.  

    As always, we wish Charlie and Shirley a fun and blessed retirement.
