Cleaning Metal Roofing

Regular cleaning is essential to ensure your metal roofing looks good and performs well. Here are the steps to clean your metal roofing:

Use a garden hose or a pressure washer to rinse the roof surface thoroughly. Start from the top of the roof and work your way down, making sure to cover the entire roof surface.

Step 4: Apply Cleaning Solution

Mix a cleaning solution of mild detergent and water in a bucket. Apply the solution to the roof surface using a soft-bristled brush or a sponge. Work in small sections, starting from the top of the roof and working your way down.

After applying the cleaning solution, rinse the roof surface again using a garden hose or a pressure washer. Make sure to remove all the cleaning solution and dirt from the roof surface.
