Another sign of mold on your roof is odor, which may occur before you notice the mold. If you discover a terrible odor in the rooms, inspect the roof shingles, attic, and ceiling. You can also treat them to kill any mold that may have grown on them.

How To Remove Mold from The Roof

Mold causes a lot of damage to the roof. To prevent roof damage and health effects, follow these steps to remove the mold from the roof.

Step 1: Make A Bleach Solution

The best mold removing detergent is a mixture of bleach, water, and trisodium phosphate. Since handling chemicals with your bare hands irritates, ensure you wear gloves and a breathing mask before mixing them.

To make the detergent, mix ¼ part of chlorine and ¾ part of the water in a bucket. Add a tablespoon of trisodium phosphate and stir. Lastly, pour the solution into a pump sprayer ready to spray the roof.

Step 2: Clean the Shingles

Sweep any loose particles of the mold off of the shingles before spraying. But before climbing the roof to sweep, put on the correct climbing gear and use a sturdy ladder for safety. You should also cover the plants next to the roof.

When scrubbing, use a long-handled brush with moderately tough bristles to lose the mold particles. You should sweep the mold particles in the slope direction to prevent them from getting stuck in between the shingles.

Step 3: Spray the Roof

Once you’ve gathered all of the loose mold particles, take your spray bottle up to the roof and spray it. To prevent the solution from draining, work from the bottom to the top of the roof. Avoid using a pressure washer when spraying because the high pressure damages the shingles. Also, clean the shingles when cool and cloudy to ensure the solution does not evaporate before killing the mold.

Step 4: Rinse the Solution

Fill the sprayer with clean water or use a garden hose to clean the roof. When rinsing, pass the water on every part of the roof touched by the chemical and remove all the remaining mold particles.

Failure to thoroughly cleanse the chemicals could cause permanent bleaching on the shingles, leading to discoloration. You can also use the same mixture to treat your roof yearly and prevent mold growth.

Final Words
