General Info

Cosam Contracting began in 1985, serving customers all over Ohio and into Kentucky with great respect and quality workmanship. That tradition continues today. Professionalism and excellent workmanship has earned us repeat business and growing clientele mostly through references and positive reviews. “That’s how we like it. We prefer to do business the old-fashioned way, by doing a great job and being recommended to others”. Of course, being old-fashioned in character doesn’t mean without modern conveniences. The Cosam team uses the best products on the market to assure you of proper repairs and installations. One of those products is Duro-Last membrane technology, which provides the highest level of waterproofing in the industry. Holding the title of Duro-Last Elite Contractor with pride, we handle every project from small repair to complete roof replacement with the professionalism associated with that title. Offering our customers warranties and maintenance plans for convenience, and giving free estimates when requested, all our clients and prospective clients are important to us. Many customers have kindly shared positive reviews about our work and service over the years, and it is our promise to you to treat you in the same manner.
