Common Problems That Indicate You Need Your Roof Cleaned


Your roof’s exposure to the sun can leave it susceptible to Gloeocapsa magma, a form of algae that leaves dark, unsightly streaks and stains on your roof’s surface. This kind of algae is usually found on the north part of your roof and can result in “hot spots.”

Because these hot spots absorb sunlight instead of reflecting it, you can incur higher cooling costs and further roof damage over time. To be safe, have a roof cleaning expert inspect your Houston property when assessing the extent of algae damage.

Lichens and Moss

Evolved algae result in lichens while damp surfaces promote moss growth. You can distinguish a lichen from moss by its appearance. Lichens typically look like flat, green circular patches while moss has a green, fuzzy texture.

Moss has rhizoids, which are root-like appendages that cling to your roof and catch other dirt blown by the wind. When left unchecked, lichens and moss can dig into a roof’s shingles, accelerating damage that often leads to roof replacement.


Along with algae, molds are naturally occurring plant growths that threatens a roof’s lifespan. Molds appear as black, brown, and dark-green blemishes that result from moisture deposits brought by humid and rainy weather.

Leaving mold unchecked ruins not only a property’s curb appeal but also poses significant health risks. Make it a point to purge your roof of molds regularly.


Mildew is another form of fungus that is black, light grey, or pink and distinguished by its powdery appearance. Inadequate drainage systems are the usual cause of mildew growth, so you can expect to find them along a roof’s gutter.

Exposure to mildew for a long time can harm both your roof and your health. Since mildew has a powdery consistency, it can easily stick to your clothes, which can cause health problems such as eye or skin irritation and respiratory problems.

When addressing mildew growth, it’s crucial to contact roof cleaning specialists in Houston as they use specialized equipment and know the best practices to handle this kind of situation.
