We Have 40+ Years of Experience

M & J Roofing and Home Improvements began doing business in the Mahoning Valley over 40 years ago. The company was founded in 1977 by Mike Diaz, on the values of honesty, integrity, and quality craftsmanship. Mike dedicated himself over the next 20 years, to ensuring that every customer who chose to contract M & J Roofing, experienced those values first hand. Today, the company has been passed on to Mike’s sons, Kevin and Andy Diaz, who continue to carry on the proud tradition and business model that was championed by their father.

When contracting with M & J Roofing and Home Improvements, you are securing the guaranteed quality and professionalism that has marked our reputation in the Mahoning and surrounding counties for over 40 years. Our owners are hands-on throughout the entire project, from the initial estimate, all the way to project completion. We are family owned, family operated, fully insured, and our desire is to give the best of our family to each customer, so that your family gets the quality experience you deserve.
