Check out the roof before cleaning

First things first, make sure to check your roof for any potential leak spots. Typically, any rooftop that is around ten years old will have about 10 to 20 potential leak spots. You have to identify those leak spots and fix them.

While identifying the leak spots, you should also make sure to look out for exposed nail heads coming out of the roof. When you find any such nail heads, hammer the nails back and use a new staple wherever required. After that, mend back the shingles, and you’re all set to move on to the next step.

Use Industrial Bleach

After fixing all the leaks and mending the shingles back, the next thing you need to do is to kill all algae and make the roof look brand new again. In order to do this, you can use industrial bleach as industrial bleach is it is proved to be very effective.

You can use a sprayer to apply the bleach and let it dwell on the surface of the roof for about 15 to 20 minutes. After this, rinse the rooftop thoroughly with water running at low pressure, as it does not require a high-pressure rinse to get the bleach off the roof and keep your roof clean.

The Rinse method

The most effective way to rinse the roof thoroughly is through the Double Rinse Method. This method aims to first take the top first four rows and rinse them while walking sideways. During the next pass, rinse the next four rows while also rinsing the first four rows again. Repeat this process until you reach the end of the roof. However, remember to be soft and gentle while doing so, and be very careful as it can get slippery and risky.
