Why Does Mold Grow on a Roof?

Mold and mildew thrive on organic matter. Now you may be thinking to yourself – “my roof isn’t made of living matter?” but unfortunately, the materials that fall on your roof often are. If plants and leaves fall onto your home before a heavy rain, mold can start to grow.

Detecting Mold

The tricky thing about inspecting your roof is that it’s obviously hard to see the top of it while you’re standing on the ground. Take a walk around the outside of your house and keep an eye out for any dark, wet spots or green patches. If you’re able to see a few spots with mold, odds are it is further up your roof as well. From there, you should call a professional roofing company to secure and inspect your roof.

Getting Rid of Mold

To get rid of mold or algae, spray your roof with a 50 percent mixture of water and bleach. (Pro tip: this is the time when a lot of people like to break out their power washer, but trust us – that will only do more harm than good. Power washers can easily damage or rip off your shingles and cause more water saturation). When you’re done, give your roof another rinsing with just water.
