If your metal roof is dirty and needs a good cleaning, you can do it with a pressure washer. Here’s how:

  1. Start by locating the areas of the roof that need the most attention. These might be areas where there is a lot of dirt or debris, or areas that are particularly dirty.
  2. Choose the right pressure washer for the job. A high-pressure washer will be more effective at cleaning metal roofs than a low-pressure washer. Make sure to read the instructions carefully before starting your cleaning project.
  3. Fill up the pressure washer with water and start spraying it onto the metal roof in an area that you have designated as clean. Use short, consistent strokes to avoid damaging the surface of the roof.
  4. Wait until the surface of the metal roof is wet but not dripping, then switch to your scrub brush and start scrubbing away at any dirt or debris that has accumulated on top of it. Be careful not to damage the surface of the roof with your scrub brush!
  5. Rinse off all of the soap and water from your metal roof with a hose before letting it dry completely. You should expect this process to take around 30 minutes, depending on how dirty and dusty your metal roof is ..
