While you certainly never want to come across mold growth anywhere in your home, there can also be problems if you find it on your roof. Yes, your roof is a place where mold and algae can develop, especially in areas that stay relatively shaded from direct sunlight. If you notice the presence of mold or algae on any part of your roof, we suggest contacting your Collingwood roofers today for safe, proper removal. Not only is it an eyesore, but it can also lead to premature shingle deterioration and shorten the overall lifespan of your roof. Mold and algae, if left untreated, may also continue to spread.

While mold can be removed from the roof, it’s imperative to do it right. In this post, we’ll cover the steps to proper removal.

How to Remove Mold from Your Roof

There are a few different ways that you can rid your roof of mold, algae or moss, and they all involve accessing the roof to treat the affected areas.

Use a Hose

If you have a hose that’s long enough to reach your roof, simply spraying down the affected area may be enough to agitate and remove buildup. While it can be tempting to use a pressure washer, don’t. If you do, it could damage the roof shingles.

Use Cleaning Chemicals

It’s imperative to use the right cleaning chemicals or else you risk roof damage. We’ve listed some of the best ones to safely rid the roof of mold buildup:

  • An equal mix of bleach and water: Apply this to the affected area and then rinse it off after about a half-hour.
  • Trisodium phosphate: Mix about a half-cup of a bleach-water mix for every gallon you use. This provides a stronger cleaning than just water and bleach.
  • Oxygen bleach: If you have plants or a garden in the area where you’ll be washing your roof, consider this more eco-friendly cleaner. When applied correctly, it shouldn’t harm anything.
  • Other cleaners: There are various other microbial cleaners that you may elect to use, just make sure that they’re able to be safely applied to the roof.

Call a Professional

While removing the likes of mold, algae and moss can be performed by handy homeowners, keep in mind that you’ll need to access the roof and take the right steps to ensure your safety while you’re on it. For this reason, it’s often easier for many homeowners to hire a roofing professional to take care of this. As roofing professionals are clearing away mold, they can also check to see if there are any other areas of the roof that require attention.
