Cleaning a Metal Roof
We often get calls about Cleaning a Metal Roof and how the best way to clean one is. Cleaning a metal roof is different than cleaning any other type of roof. This is due to the fact that the roof is not near as porous as shingle or tile roofs. We do use the same solution that is used for other roofs. However, a metal roof must be rinsed thoroughly to remove the cleaning solutions prior to letting it dry.
We recently cleaned a 30,000 square foot metal roof that houses a Horse Arena. It is located here in the Houston Texas area. The roof stains had built up over a couple years, and even had caused the plastic skylights to prevent adequate sun light to get through.
Never Pressure Wash a Roof
No matter what type of roof is being cleaned, we never use a pressure washer to clean as high pressure, even at low PSI of 150 can cause damage to the roof. Our Soft Wash cleaning method was used on this Roof Cleaning and the customer was extremely pleased with the results, as you can see in the video customer review she did for us.
Due to the fact that we live in a very damp and humid environment, all roofs will algae growth. The only way to properly clean and remove the algae is to Soft Wash it. A light bleach mixture must be used in order to kill off the algae and provide for a longer lasting cleaning. This helps to prevent the algae from returning for a few years.
Our method of cleaning roofs is the only method that is recommended by Roof Manufactures and this is the reason we closely follow their guidelines. Using a pressure washer can void the warranty so we never us one. We are Certified Roof Cleaning Company.
