What You'll Need
Vinegar

Borax
Water
Tarp

Mold can grow almost anywhere if there moisture and that means no part of your house is completely safe, not even your rubber roofing. Once it grows, mold can be quite difficult to remove from any surface. Even if you do manage to clean it off once, preventing it from coming back again is a real challenge. Luckily, with the right preparation, tools, and strategies, killing mold and keeping it away for good is quite possible. The following instructions should help keep your rubber roofing free of mold for good.

Step 1 - Setting Up

While it is not the absolute strongest cleaning agent for removing mold, vinegar is still a great choice to start off with when attempting mold removal. It is common enough that you probably have some lying around already. Also, it is non-toxic, making it easy to use and stress free to clean up after with no concerns about keeping it away from children or pets. While you may end up needing something stronger, you should try using vinegar once. To start off, soak a sponge in vinegar.

Step 2 - Applying Vinegar

Use your sponge to spread vinegar over any areas of your rubber roofing that have mold growing on them. Be sure to go over the surrounding areas too because they may have early growths of mold that you cannot see. Once you have done this, leave the vinegar you have applied to sit and do its work. A few minutes should be a sufficient amount of time. Now use your sponge to wipe up the vinegar and hopefully the dead mold. 

If there is any mold left, repeat the process. If after a repetition or two there is still mold remaining, apply the vinegar a final time and wait an hour. If any mold survives, you need something stronger than vinegar to kill it.

Step 3 - Using Borax

If your mold has survived vinegar so far, give up on using it in the future. Instead, you should be using borax. Borax is a great cleaning agent, but unfortunately it is toxic, so a few safety procedures are required. First, set up a tarp that covers the areas below where you are cleaning. This helps protect plants in your yard, and helps you completely remove the toxic borax once you are done. Be sure children and pets are kept away from both your work area and the tarp.

Next, mix 1/2 cup of borax with 1 gallon of water. Soak your sponge in it, and then apply it to the affected areas. Again, leave the mixture to soak for a few minutes before wiping it away. Borax is particularly good at removing mold in this way. However, you may need to go over the affected areas multiple times in order to remove the mold.

Step 4 - Finishing Up

Once you have removed the mold from your roof, you must remove the borax as well. Rinse it away with water and collect it in the tarps you put down previously, then dispose of it as you would any other toxic chemical.
