• Performing precise and skillful manipulation of small objects.
• Being active and proactive in regards to physical activities that require considerable use of your arms and legs and moving your whole body, such as climbing, lifting, balancing, walking, stooping, and handling materials.

• Installing vapor barriers or layers of insulation on flat roofs.
• Covering exposed nailheads with roofing cement or caulking for preventing water leakage or rust.
