Mold and algae should be tackled promptly to keep your roof’s structural integrity and functionality. The formation of mold can also put you and your people’s health at risk, not to mention is tricky to remove. Thus, here are some suggestions that may help you remove mold and algae from your roof.

How To Pinpoint Algae & Mold On The Roof

Mold typically starts to form in moist regions of your attic and can quickly reach the roof. You may notice it in three different shades: green, brown, and black. Algae, on the other hand, has a bluish-green hue. Both of these can quickly form on the shingles and expand in moist climates.

How To Remove Mold & Algae From Your Roof

If there is mold developing beneath the shingles or over your roof, you will see that there are more than just external spots. In this case, you should hire professional contractors to inspect the mold in your roof and evaluate the level of damage.

Taking off mold and algae from your roof may need you to jump right over the roof. Hence, most folks choose to contact a roof fixing company or expert to clean it up and to make sure that the layers underneath are not impaired.
If you are going the DIY route, though, here are some tips to help you remove mold and algae from your roof. You will have to gather the following:

  • A hose with a wand or nozzle attached. However, you have to ensure that there is no pressure during washing or you may ruin the roof’s surface.
  • Oxy bleach detergents can be applied in place of laundry bleach if you fear that the waste will harm your grass or garden
  • You may also use a mixture of water and bleach in equal ratios. You may apply the mixture with a spray bottle and let it sit and work for 30 minutes, then rinse with light water pressure. The ideal mixing ratio for a strong yet safe cleaning is ½ cup of bleach per gallon of water. You may also use a Trisodium Phosphate solution.

How To Keep Mold and Algae From Returning

The easiest way to keep algae and mold from coming back is to stop humidity from coming in the first place. You may waterproof your roof by hiring a professional roofer or company.

Another crucial step to prevent the accumulation of mold and algae is to clean out your roof regularly. Make sure that you remove any dirt and debris and that the gutters are clear and functional to let water drain out. Also, trim down any overstretching tree branches that may hang over or near your roof.

Arrange a regular roof check at least 2X a year to make sure that bacteria formation is eradicated. Roof fixing companies may also repair the shingles if ruined or bent, mitigating the risk of encountering serious algae and mold problems in the future.
