How to Use a Roof Scarfer Safely and Effectively

By Kevin Malone

Using a roof scarfer properly is crucial for both efficiency and safety. Here's a general guide on how to use a roof scarfer effectively:

Preparation and Safety Measures

  • Inspect the Roof: Identify any potential hazards such as loose materials, debris, or weak spots.
  • Wear PPE: Use appropriate personal protective equipment (PPE) including safety goggles, gloves, hearing protection, and non-slip footwear.
  • Check the Scarfer: Ensure that the scarfer is in good working condition and all safety features are operational.

Set Up the Roof Scarfer

  • Position the Scarfer: Place the roof scarfer at the edge of the roof, ensuring it is securely positioned.
  • Adjust Depth Settings: Set the depth on the scarfer according to the type and thickness of the roofing material to be removed.

Start the Scarfer

  • Power On: Turn on the scarfer according to the manufacturer's instructions.
  • Reach Operating Speed: Allow the scarfer to reach full operating speed before beginning to remove the roofing material.

Begin Scarfing

  • Position and Move: Position the scarfer on the roof and slowly move it across the surface, working in manageable sections.
  • Apply Steady Pressure: Apply steady pressure to the scarfer, but avoid forcing it, as this could damage the roof deck.
  • Systematic Pattern: Work systematically, moving in a consistent pattern to ensure thorough removal of the old roofing material.

Monitor Progress

  • Check Removed Material: Keep an eye on the removed material to ensure it is being properly cleared away from the roof surface.
  • Depth Check: Periodically check the depth of material being removed to ensure it matches the desired setting on the scarfer.

Handle Obstacles Carefully

  • Navigate Obstacles: Take care when navigating around obstacles such as vents, chimneys, or skylights.
  • Avoid Perimeter Hazards: Use caution near perimeter warning lines to avoid using machinery outside of the protected space.

Clean Up

  • Clear Debris: Periodically stop the scarfer to clear away removed debris from the roof surface to prevent buildup and potential hazards.
  • Dispose Properly: Dispose of removed roofing material properly according to local regulations.

Shutdown and Maintenance

  • Power Off: Once the scarfing is complete, turn off the scarfer.
  • Clean the Scarfer: Thoroughly clean the roof scarfer to remove any accumulated debris.
  • Perform Maintenance: Conduct necessary maintenance tasks as outlined in the manufacturer's instructions to keep the scarfer in good working condition.

By following these steps, you can safely and effectively use a roof scarfer to remove old roofing materials in preparation for re-roofing. However, always refer to the specific instructions provided by the manufacturer of your scarfer for the best results and safety practices.
