Who We Are

Function Enterprises incorporated has been family owned and operated since its inception in 1983.  David Chiles created the business and along with the help of brother John Chiles they operated the business successfully in its early years.  Later would come Robert Gray, a longtime friend turned team member; as a roofer, estimator then official shareholding partner in 2004, Robert has been a critical factor in Functions success thus far.  Today Michelle Martel OWNER/CEO (Dave’s Daughter), Ryland Gray OWNER/ESTIMATOR (Robert’s Son) along with Brian Martel General Manager (Michelle’s husband) now own and operate the business.  Extended family continues to join the team to this day, we also have many father/son team members out providing quality roofing work with a Family and Team in mind.  See just a small portion of our team below.
