Roof Mold VS Algae: How Can You Tell the Difference?

It’s easy to assume that what’s on your roof is mold when it’s actually algae. Either way, both of them can make your roof look dirty and unsightly. Knowing the difference between the two can help you determine the best way to get rid of them.

A roof repair expert explains what makes algae different from mold and how you can tell which is on your roof.

Algae

Similar looking to moss, algae is an organic growth that spreads through airborne spores. It’s more common in areas with humid conditions. You can usually see it in asphalt roofing shingles. While you may be alarmed that they can harm the efficiency of your roof, they won’t. They won’t cause damage to your roof nor risk the health of your family.

However, roof algae can negatively affect your home’s curb appeal. If you’re thinking of selling your home in the future, make sure to address this growth immediately. Buyers are more attracted to homes with cleaner-looking roofing systems.

Mold

Mold may not be as common as algae but it can put your family’s health at risk. Mold spores can trigger headaches, eye irritation, as well as asthma and allergy attacks. It can also contribute to poor indoor air quality and different respiratory health risks.

Usually, mold forms in poorly ventilated attics and basements because it thrives under damp, warm conditions. Mold inside your home can spread to your roof, siding and deck. If you don’t have it inside your home, you may only be dealing with algae. Moreover, make it a habit to regularly check your crawlspaces, to help detect mold before it spreads.
