Mold is a type of fungus that tends to grow in damp environments. Its spores can be harmful to your respiratory system, and it can weaken walls and other structures. While many homeowners know to check for mold in their bathrooms and basements, it’s important to note that mold can also grow on the roof. It’s especially important to check for this during the spring, when heavy rains often create the exact conditions that lead to mold growth. 

How Does Mold Affect the Roof? 

Mold usually forms due to excessive moisture. If heavy rains occur and your roof does not properly drain, it could begin to form on your shingles or underneath the roof itself. As it spreads, it can weaken the structure of your roof and cause the shingles or underlayment to crack or decay. Its spores can also make their way into your home and cause respiratory or skin irritation for your family.

How Do You Know if You Have Mold?

Visually, mold tends to appear as a dark stain on your roof’s surface. You might also notice a fuzzy brown or green substance showing up around the flashing or other roof features. Additionally, a musty smell in your attic or around the exterior of your home is often a surefire sign of mold growth.

What Can You Do About It?

If you do have mold, don’t try to get rid of it yourself, as the process can be dangerous. However, you can trust an experienced roofer to power-wash the surface and replace any tiles, if necessary. Additionally, make sure to get regular roof inspections, so you can catch any potential mold growth early on, before it leads to structural damage, and make sure your roof has proper drainage to limit moisture collection.
