How to Remove Mold from Your Roof

Do you have black streaks or green moss on your roof? Florida residents are no strangers to the sight of mold growing on their roofs or under their shingles. Untreated algae, moss, or other plant growth can lead to wood rot and erode asphalt in shingles. It may also attract rodents.

Hiring an experienced roofer to remove mold from your roof can be a challenging task. Here’s a guide for removing mold from your roof if you’re up to the challenge.

What Causes Mold & Algae to Grow on Your Roof?

Florida’s humidity and rain create ideal conditions for mold and algae growth on your roof. Mold can develop on your roof from damp areas, such as leaking pipes, clogged downspouts and gutters, or overflowing drains.

Mold and algae can also thrive on your roof depending on its design. Steep slopes tend to dry faster, making mold less likely to grow. Flat roofs that are in the shade will be more susceptible to problems.

How to Remove Mold or Algae from Your Roof

Mold is a problem that should be dealt with as soon as possible. You’ll first need a solution that can kill the fungus. The most common and effective solution for your roof is a mixture of one part bleach to one part water. Applying this solution to all surfaces affected by mold growth and damage will effectively eliminate it.

You might also believe that power washing will do the trick when applying the solution. However, if your roof has shingles, power washing may be too harsh. Using a hose with a special attachment can help you avoid causing further damage to the roof.

Prioritize Safety

Safety should always be your primary concern when deciding to tackle tasks yourself. You’ll need to clean your roof from the top down. The solution can make surfaces slippery, so wearing safety gear is essential. A harness or safety gear is the best way to prevent falls and injuries while hosing down your roof.

If you’re uncertain, consider contacting a roofer that specializes in mold elimination. Hire a top-rated roofer like Roofing.Co to inspect your roof and handle mold removal.
