How can you tell if the black or green streaks on your roof are mold or algae? It’s easy to mistake algae growing on your roof for mold, but there are key differences between the two.
Fields Roof Service, your trusted roof contractor, explains these differences and shares tips on identifying mold and algae below:
Which Side of Your Roof Can the Streaks Be Found?
The location of the black and green streaks can indicate whether it’s algae or mold that’s growing on your roof. Algae are moss-like plants that need sunlight, so they only grow on the parts of your roof that receive ample sunlight. Mold, on the other hand, doesn’t need sunlight, but it does need moisture. As such, it’s usually found in hidden parts of your roof where rainwater tends to accumulate.
The Crucial Difference Between Mold and Algae
Aside from cosmetic issues, algae are mostly harmless. The worst thing algae can do is lower your curb appeal. The same thing can’t be said for mold, which eats away organic materials such as wood and as such can damage your roof. Not to mention mold spores—which can trigger allergy flare-ups and aggravate respiratory conditions—are a health risk you shouldn’t ignore.
Preventing Mold
One thing you should remember about mold damage is that it usually goes hand in hand with moisture damage. As such, if there’s a roof leak, there’s a chance mold has already formed in parts of your roof. Remember: Mold thrives in damp environments.
Adequate roof ventilation is vital to preventing the formation of mold. If there aren’t enough vents in your roof or attic, heat and humid air could become trapped, creating a damp environment that’s the perfect breeding ground for mold.
