Roofing mold presents unique and potentially serious dangers to a home. It can weaken the structure of the roof and cause leaks and water damage. It also presents health risks to those who live in the home. For these reasons, homeowners should be vigilant about identifying and mitigating roof mold. Below is some guidance to help you with this process.

Signs of Roofing Mold

On the surface of the roof, you might see dark-colored patches, stains, or streaks. But not all mold growth is so obvious. Some will occur under the shingles, where the dark and moist environment is ideal for mold growth, and this location isn't visible just looking at the roof. The growth might not only become apparent until the mold has penetrated the fascia and underlayment, weakening these sublayers and causing water to leak through.

So, your first sign of mold might be new, unexplained leaks in the ceiling or walls. Another indicator is a damp, musty odor inside the home. The closer you get to the roof, the stronger the smell will become, giving upper floors a more pronounced moldy smell.

How to Mitigate It

If your roofing is in a shady area and not exposed to the sun, water will have a harder time evaporating, which significantly increases your chances of mold growth and damaging leaks. Keep tree branches trimmed so they don't overhang the roof and block sunlight.

Regular, seasonal gutter cleanings will give water a clear path to run off the roof and prevent it from pooling and triggering mold. Ridge vents can be installed at the peak of a sloped roof to encourage healthier airflow, which helps humidity escape the attic and reduces the likelihood of excessive moisture—and mold—on the roof.
