Where Can You Usually Find Mold on Your Roof?

Mold can grow anywhere there is moisture and oxygen. It’s among the last things you want to see in your home because it can deteriorate building materials and compromise your family’s health. Asthma attacks, sneezing, runny nose, skin rashes and headaches are common health risks associated with mold growth. Moreover, this issue often occurs in leaky, damaged or poorly ventilated roofs. 

Here’s where you can usually see mold growth in a roofing system. 

Under the Shingles

Shingles protect your roof and your indoor spaces from the elements. However, moisture can infiltrate and get trapped under lifted, damaged or improperly installed shingles, creating the ideal environment for mold growth. Routine inspections can help experts identify and immediately address areas where mold might begin to take root before it spreads. 

Around Gutters and Downspouts

Gutters and downspouts lead water away from your roof and home’s foundation. Over time, they can get clogged with leaves, twigs and debris, resulting in standing water. When not dealt with quickly, moisture can seep into the roof deck or fascia boards, making them a hotspot for mold growth. You can easily avoid this problem by scheduling gutter cleaning at least twice a year. 

Shaded Areas

Parts of your roof that receive little to no sun are more susceptible to mold growth. Sunlight naturally dries moisture, discouraging mold growth. If your home is surrounded by large trees or near buildings, mold is more likely to grow on your roof. Trimming tree branches to increase sunlight exposure can help reduce the risk of mold in shaded areas. 

Near Chimneys and Vents

It isn’t uncommon for mold to appear in areas around chimneys and roof vents. The flashing used to seal these structures can sometimes fail, allowing water to penetrate and become trapped. Regularly checking the seals and flashing around chimneys and vents for wear and tear can prevent water infiltration and mold growth.

On Roof Valleys

Organic debris like leaves, branches and dirt can accumulate in valleys or areas where two roof planes intersect. These materials hold moisture, creating the ideal environment for mold to flourish. Keeping your roof debris-free is crucial in preventing mold growth.
