About Us


our mission

Who are we?

Joe and Dawn Gentle started JG Contracting in August 2015 as a Roofing, Gutters, Windows, Siding and Garage Door company. By 2017 , JG grew to over 10 million in sales and became one of Kansas City’s top exterior contracting companies. JG prided itself as a contracting company that always strove for 100% customer satisfaction. As our roofing business grew so did our Siding and Windows business and in 2023 JG sold their roofing division and became JG Siding and Windows with the same mission… 100% customer satisfaction.
