Cleaning solar panels before installing proofing is crucial for maintaining roof integrity and ensuring long-term performance. Whether pigeons or possums have taken up residence, a thorough cleaning helps prevent future issues and protects your investment.

Why Is Cleaning Solar Panels Before Proofing Necessary?
1. Remove Corrosive Bird Droppings
- Bird droppings, especially from pigeons, are highly corrosive and can damage iron roofs over time.
- Cleaning removes these corrosive materials before they cause long-term damage.
2. Prevent Water Flow Blockages
- Loose debris under panels can wash down and collect inside the proofing mesh, reducing water drainage.
- Blockages during heavy rain can lead to water pooling and roof leaks, even on tiled roofs.
3. Maintain Panel Efficiency
- Dirty panels reduce solar efficiency by blocking sunlight.
- Cleaning ensures optimal energy output while preparing the surface for proofing.
The Role of Proofing Mesh in Protecting Solar Panels
When Peter the Possum Man installs proofing mesh, it serves to:
- Keep Wildlife Out: Prevent pigeons, possums, and other animals from nesting under solar panels.
- Allow Airflow: The mesh permits air circulation and rainwater to flow through naturally.
- Minimize Debris Accumulation: Although effective, some debris may still collect along the mesh over time.
What Happens If You Don’t Clean Before Proofing?
1. Increased Risk of Corrosion
- Without cleaning, corrosive bird droppings remain trapped under the proofing, accelerating roof damage.
2. Blocked Water Flow
- Unremoved debris can accumulate and block water drainage, especially during storms.
- Water blockages increase the risk of leaks, even on tiled roofs.
3. Costlier Maintenance Later
- Debris left unchecked may require more extensive cleaning in the future.
- Preventative cleaning is a small upfront cost compared to long-term roof repairs.
How Cleaning Extends the Life of Your Roof and Panels
Proper cleaning and proofing work together to protect both your solar panels and your roof:
- Delays Debris Accumulation: Cleaning ensures any material collecting along the proofing mesh is minimal.
- Prevents Drainage Issues: Maintaining clear water flow reduces the risk of leaks or pooling.
- Preserves Roof Integrity: Removes corrosive materials that can degrade roof surfaces over time.
Steps to Clean Solar Panels Before Proofing Installation
1. Pressure Wash Under Panels
- Use a pressure washer to remove bird droppings, debris, and dirt from the roof under the panels.
2. Clean the Solar Panel Surfaces
- Wash the solar panel surfaces to restore optimal energy efficiency.
3. Inspect Roof Condition
- Check for pre-existing damage or gaps, especially in tiled roofs where small blockages can worsen drainage issues.
Long-Term Maintenance After Proofing Installation
1. Periodic Panel Cleaning
- Clean the solar panels every few years to maintain efficiency.
- During cleaning, remove any debris collected along the proofing mesh.
2. Regular Roof Inspections
3. Wildlife Prevention
- Inspect the proofing mesh and roof to ensure drainage remains unblocked.
- Ensure proofing mesh remains intact to prevent pigeons or possums from re-entering.
Why Professional Cleaning and Proofing Is Worth It
Given the investment in solar panels and the importance of roof maintenance, hiring professionals ensures:
- Thorough Cleaning: Experts can safely pressure wash the panels and roof.
- Effective Proofing Installation: Properly installed mesh minimizes future debris buildup.
- Peace of Mind: Protects your roof and panels from long-term damage caused by wildlife and debris.
