How to Remove Mold from Your Roof

Mold on RoofWhen you see what looks like black streaks on your roof and you’re worried that it is the early signs of a serious issue, take heart. Although it’s called “roof mold,” it’s actually a type of blue-green algae. As roofing contractors in Daytona Beach, FL, we’re very familiar with this problem at Robeson Roofing, Inc., and we’re going to let you in on the technique that professionals use to remove this algae.


It’s not something to be ignored or taken lightly because if left unchecked, it can lead to damage, but the solution is an easy one. The way most roofing contractors attack this issue is by using a zinc sulfate solution on the shingles. The solution kills the buildup, and then it’s washed away, or the rain will remove it. Keep in mind that a good roofer will not use a high-pressure spray to clean your roof as it may damage and lift shingles. It’s also not a good idea to use bleach to clean “roof mold,” as some contractors do, as it’s tough on shingles and not environmentally friendly.


Once the roof is clean, roof contractors often suggest a yearly application of zinc sulfate to prevent the problem from recurring. It pays to keep your roof in excellent condition. Protect your roof, and it will protect your home.
