As a roofer, you install and repair a variety of different roof types–from common shingles to more complex green roofs. You may assess roof damage caused by rain or other environmental factors, and provide property owners with cost estimates for repairs. Other jobs in the roofing industry include sales positions, estimators, account managers, superintendents, and administrative assistants. You can work as an independent contractor or do work through an agency. Support jobs are typically found in agencies and are designed to help roofers do their job more efficiently.
