Do you have any idea how important the roof in your house is? If you do, then you might also be well-acquainted with the significance of regular roof maintenance and repair. What people basically do is overlook the condition of the roof until major problems arise. If you had regularly cleaned the roof in the simplest way possible, you wouldn’t have to surf the internet, like you’re doing now, to find easier and more effective ways to clean the roof.

I am here to present you a couple of ways to clean the roof with ease and efficiency, hope you’ll go through it, and conclude – whether you’re siding along with a good all DIY, or going to call the professionals.

Ways to Clean the Roof

The kind of roof that you’ve installed helps in determining what sort of treatment your roof needs during maintenance. No matter which method you use to clean the roof and maintain it, removing algae from the roof should be your major concern. Two basic ways of removing algae are:

  1. Pressure Washing: this process of algae removal is the most effective in case of metal or tiled roof.
  2. Chemical Washing: any sort of roofing material can be easily cleaned with chemicals. Sodium hydroxide and all kinds of chlorine solutions are the most commonly used chemicals, when it comes to cleaning your roofing.

How to Pressure Wash Your Roof

It is obvious that you’ll need a pressure washer to pressure wash your roof. You can easily find the required apparatus in the local equipment hire shop or any nearby hardware store. However, what you should know before you start the power washing thing is that this method is a good way to remove algae from the roof, but not a foolproof method.

Followings are the steps to follow if you want the power-washing of your roof to become far more effective:

  1. Avoid blasting the water up, and start from the peak of the roof, slowly working your way down. If you don’t do as directed, the blasting of the water may directly affect tiles or sheets of roofing materials.
  2. Always keep in your mind to start from a smaller area. Using medium pressure in the cleaning wand and keeping the head 30 cm away from the roof is the right thing to do. Then, you should gradually lower the machine or the wand, directing the pressure onto the mold, until it is completely removed from the roof.

You should also remember that heavy pressure from the wand may damage the roofing material. Thus, you got to inspect the roof as soon as you finish the power-washing.

  1. Start by standing on a dry area to begin the task. As you move on with washing the roof, stand on spots that are already cleaned. You should know that algae gets slippery when wet, so be cautious not to stand on unclean roof areas.


Cleaning with Chemicals

As stated earlier, chlorine is usually a better option for DIY roof cleaning than sodium hydroxide, as it is comparatively safer. However, it’s not like you shouldn’t be careful when you’re using chlorine. Make sure that you use protective gloves and eye glasses for your own safety. Other safety tips are mentioned below.

The best thing to do in case of chemicals is to leave them as they are, and let them do the job, as far as possible and practicable. Algae and moss are so easily removed by chemicals that a simple rinse, using them, should be enough. Brushing the roof with a soft bristled brush can also be fruitful. BUT, don’t scrub hard.

Safety Tips

  1. Don’t try cleaning a steep roof all by yourself. Algae and Moss make the roof too slippery. Take help from professional cleaners in such cases.
  2. Avoid strong chemical solutions, and be careful not to drop them onto the plants below. The chemicals that kill algae can also take the life of the plants that you’ve been growing.
