Roof Mold Treatment

Roof Mold Treatment
 

Steps to Removing Mold and/or Algae

  • Apply your liquid solution with a garden sprayer
  • Let the solution sit on the surface for around 20-3o minutes
  • Rinse the solution off with a garden hose
  • If mold or algae is still on the roof, use a medium-stiff bristle brush to gently scrub the rest off.
  • If there is still mold or algae on the roof, let everything dry (after rinsing it off with water) and spray on the solution again and repeat the above steps. 

Other Tips & Tricks

  • Do not stand on the wet areas. This can be slippery and cause you to slip and fall off the roof. 
  • Start working on the top and work your way down the roof. This will make it easier for two reasons:
    • 1) you won’t get stuck on the top of the roof waiting for it to dry so you don’t slip and fall, trying to walk off the roof. 
    • 2) Starting on the top is good because all the debris and other items will trickle down to the bottom as you clean, so no use in starting from the bottom if debris is going to just get the bottom dirty again. 
  • Do not let the cleaner dry. Make sure you rinse the cleaner off. 

If you can’t make it to the store or don’t want to purchase one of the many popular liquid solutions, try these DIY recipes. Make sure to we the surface first before applying the below DIY cleansers. Let it sit for 20-45 minutes then scrub your roof gently with a soft-bristle brush. Then make sure to rinse off the cleanser with water. 

  • 500 ml chlorine bleach + 7.5 liter of water
  • 240 ml dishwashing soap + 7.5 liter of water
  • 450 grams powdered oxygen bleach + 7.5 liter of water
  • 500 ml chlorine bleach + 7.5 liter of water

Keep in mind that mold and algae are bound to grow back if preventative measures are not taken. See our blog post “Roof Mold Prevention” to see how.
