Understanding Roof Vent Boots

A roof vent boot is a flexible rubber or plastic component that seals the gap between the roof vent pipe and the roof surface. Its primary purpose is to prevent water, debris, and pests from entering the attic space.

Tools and Materials Required

Safety Precautions

• Wear safety glasses and work gloves to protect yourself from sharp edges and debris.
• Use a sturdy ladder and ensure it is securely positioned.
• Be aware of your surroundings and avoid working in inclement weather.

Step-by-Step Instructions

1. Locate the Vent Boot

• Climb onto the roof and locate the roof vent.
• The vent boot is typically a round or square-shaped rubber or plastic piece that surrounds the vent pipe.

2. Remove the Old Boot

• Using a utility knife, carefully cut around the perimeter of the old boot, being careful not to damage the roof or vent pipe.
• Remove the old boot and any debris or sealant that may have accumulated.
