24/7 Kostex was formed in 2016 as a full-service roofing company. After only 5 years we transformed our small roofing team into a thriving business that places its customers satisfaction before anything else. We have expanded our reach to handle the greater Chicagoland area, as well as Milwaukee, Wisconsin. Our growth has increased over the years due to our reputation and customer referrals. Our goal is to continue to thrive and stay at the top of Chicago’s best roofing companies!
