How to Clean a Galvanized Metal Roof Using Homemade and Commercial Cleaners

The galvanized metal roof makes an eye-pleasing, durable, and low-maintenance material. Still, it requires cleaning as a form of maintenance at least once. Read below about how to clean a galvanized metal roof using a homemade solution and the best commercial cleaning products out there.

How To Cleaning Galvanized Metal

A galvanized metal roof sheet is made of steel with a layer of zinc on its surface, resulting in a highly durable roofing material that doesn’t need a lot of maintenance. It has great resistance to corrosion and rust while still looking beautiful on its own without demanding paint or other types of covering coats.

That being said, a galvanized metal roof is not immune to buildup of moss and dirt after some time. Moss development results in ugly green stains on the roofing sheets, while dirt accumulation can be boosted by snow and other pollutants.

There are plenty of ways a galvanized metal roof can be cleaned, but using everyday household ingredients like water and soap is probably the most cost-effective method.

Using this method, you’ll need water, dish soap, bucket, cloth, soft-bristled brush, bleach, hose, metal polish, and gloves.

Follow the guideline below:

  1. Clean light dirt on your galvanized metal roof by spraying them with a hose.
  2. Prepare 3 to 4 gallons of water inside the bucket, then pour 4 cups of bleaching powder. Mix them well.
  3. Dip your brush inside the mixed solution, then scrap the dirt on the roof. You may clean the roof from top to bottom or from one side to the other, according to the pitch of your roof.
  4. Brush until the roof is cleaned, then rinse the cleaning solution.
  5. Use a cloth to rinse and dry the roof, then use the cloth to spread metal polish on the roof.
  6. Allow to dry, and your roof should be clean and all shiny afterward.
