Your responsibilities include determining the appropriate materials and processes to repair and waterproof a roof, ensuring clean and proper application of caulking and other compounds, and following company guidelines to complete each task. Job duties involve climbing up and down ladders, navigating difficult terrain while at high elevation, and working in all weather conditions to meet deadlines.
