The owner of ACI Exteriors has worked as a contractor for over 20 years and served in the U.S. Marine Corps before opening his own business. He has also earned his GAF Master Elite certification. For the last eight years, Shawn Gaffney has built his business around the values he learned growing up in Missouri and serving this country. Installation and home repairs performed on roofs, windows, gutters and siding are generally a big investment. When homeowners in the St Louis area need a roof replacement because of peeling paint or missing shingles, they want to make sure that they are working with a company they can trust to do a good job the first time. Since 2002, ACI Exteriors, a company out of O'Fallon, has been helping customers in St Charles County and nearby areas with their roofing, siding, gutter and window needs. The business is built around "quality, integrity, value," three ideals that owner Shawn Gaffney and his experienced staff tries to live up to with every project.
