What Causes Fungus to Grow on the Roof

The longevity of your roof in Alpharetta greatly depends on the weather and the environment in which it is located. Fungi can easily grow on roofs in humid or rainy conditions. The fungus keeps the roof materials moist, which causes rot. Overgrowth of mold occurs when there is excessive moisture from rain or humidity. As a result, your roof will appear to be covered in black stains, discolored streaks or green growth.

Moisture is another factor that attracts moss, which is harmful to your roof. Shakes and shingles can rot due to water seeping into the wood.

Algae

A fungus called algae can also cause damage to roofs if it isn’t controlled immediately. Algae that are attracted to moisture can devour your shingles.

The underlying factor that contributes to all these different fungi infestations is moisture and humidity. Remember, the two most dangerous fungi are Mold and Mildew. Long-term exposure to these can cause serious respiratory problems in your family.

Mold and Mildew Growth

The standing water and humidity, the rapidly growing spores and wood rot are quick and fertile breeding places for mold. Often, the damage is done well before the mold is discovered, as mold on the outside of the house is usually indicative of mold on the inside of the house.

Besides affecting the appearance of your Alpharetta roof, mold can also cause structural damage to your home. The holes in your roof can let moisture and water into your home and damage the wood beneath.

Preventive Cleaning is Key

Preventive care is the best form of treatment. Regular cleanings can take care of algae before it becomes a problem, and before it gives way to rot, mold and mildew. Overhanging branches may cause excess water buildup, so make sure they are trimmed back away from your roof. As a final note, make sure your attic and roof are ventilated effectively using ridge vents.

Make sure that you consult professional roof cleaners. They can get your roof back to brand-new condition, free of algae and any other growth problems. To prevent bigger problems from developing on your roof, you should inspect it regularly and have it cleaned.
