Roof Power Washing

Power washing your roof can be a great way to clean off dirt, moss, algae, and other debris. Here are some key considerations and steps for safely power washing a roof:

Safety Precautions

1. Use proper safety gear: Wear non-slip shoes, safety glasses, and gloves.
2. Secure your ladder: Make sure your ladder is on stable ground and secure it at the top.
3. Avoid working alone: Have someone spot you or assist in case of an emergency.
4. Be mindful of power lines: Ensure you are aware of the location of power lines and maintain a safe distance.

Equipment

1. Pressure Washer: Use a pressure washer with a PSI rating of 1500-3000. Too high a PSI can damage the roof.
2. Cleaning Solution: Use a roof cleaner that is appropriate for your roof type (asphalt shingles, tiles, etc.). Some pressure washers have detergent tanks for this purpose.
3. Safety Gear: Non-slip shoes, safety harness, gloves, and goggles.

Steps for Power Washing Your Roof

1. Inspect the Roof: Check for any damage that could be worsened by power washing, such as loose shingles or tiles.
2. Protect Surrounding Areas: Cover plants and other areas below the roof with tarps to protect from runoff and cleaning agents.
3. Apply Cleaning Solution: Use a roof cleaner and apply it according to the manufacturer’s instructions. Allow it to sit for the recommended time to break down algae and dirt.
4. Rinse with Pressure Washer: Starting at the top, use a wide spray nozzle to rinse off the cleaning solution and debris. Use even, sweeping motions and keep the nozzle at a consistent distance from the roof to avoid damage.
5. Final Inspection: Once the roof is clean, inspect for any damage that may have occurred and ensure that all cleaning solution and debris have been properly rinsed away.

Tips

• Low Pressure: Always start with the lowest pressure setting to prevent damage.
• Angle: Spray at a downward angle to prevent water from getting under the shingles or tiles.
• No Harsh Chemicals: Avoid using bleach or harsh chemicals that can damage your roof or harm the environment.

Alternatives

• Soft Washing: If you’re concerned about the potential damage from power washing, consider soft washing, which uses lower pressure and specialized cleaning solutions to gently clean the roof.
• Professional Services: Hiring a professional roof cleaning service can ensure that the job is done safely and effectively without risking damage to your roof or injury to yourself.
