In union roofing jobs, you build and repair residential and commercial roofing systems. As a union roofer, your main job is to complete the work negotiated by the union you decided to join. This involves traveling to each job site, ensuring each roof is installed or repaired correctly, and helping other union members as needed. As a union member, you are expected to pay union dues and may have other responsibilities, such as participating in a general strike against employers who violate the terms of their union agreement. Experienced union roofers frequently help train apprentices.
