Roof algae may look unbecoming but it is easily managed.

A roof is about more than protecting your home from the elements; it also informs curb appeal, and unsightly algae detracts from the look of your home’s exterior by making it look dated and dirty.

Learning what causes algae on roof shingles will help you in finding ways to prevent it.

What Causes Algae on Roof Shingles?

Spores are carried by the wind, and when those spores land on your roof, it causes a buildup, which leads to discoloration. The good news is that the discoloration from algae won’t damage your roof, but it diminishes curb appeal, so it’s important to find a way to prevent and eradicate it.

How to Get Rid of Algae on Roof Shingles

If you’re looking for an inexpensive DIY method of removing algae from your roof, consider this:

Mix a 50/50 solution of water and household bleach. Using a sprayer that attaches to the end of a garden hose, spray the entire roof. Note: You may be tempted to use a power washer, but doing so can shorten your roof’s lifespan, and that’s why using the hose sprayer is a preferred option.

Hiring a professional roofing company is another option when you’re looking for how to get rid of algae on roof shingles. Experienced roofers know how to successfully deal with algae removal, and they can also provide routine inspections/cleanings that allow algae growth to be identified and removed before the buildup causes unsightly stains.

How to Prevent Algae on the Roof

Preventing algae is easier than removing it, and there are some steps you can take to stop this issue from taking hold. Here are a few answers to the question of how to prevent algae on the roof.

  • Remove any tree branches that hang over or near your home.
  • Regularly remove leaves and other debris.
  • If drain spouts cause water to travel over your roof, redirect them.
  • Ensure your gutters are kept clear of debris.

Another way that algae spores may find their way to your roof is when they blow over from the roof of a neighbor who has algae on their roof. That means when you take the time to prevent or remove algae from your home’s roof you could be helping your neighbor prevent algae buildup as well.
