Mold is a fungus that grows in dark, moist environments, which means that the tight spaces in and around your roofing shingles offer an ideal breeding ground. If left unchecked, mold is not only unsightly, but it can cause potentially serious health problems, like allergic reactions, cold-like symptoms, and respiratory issues. To prevent any of these possibilities, learn the signs of moldy shingles so you can promptly repair your roofing.

Discolorations

Mold will often discolor shingles with green, brown, or black patches of varying sizes. As the mold grows, these patches will also grow. In situations where a roof is currently leaking or has leaked in the past, mold will discolor more than just the shingles. 

You may be able to see dark-colored stains in any area where water has permeated the roofing, including under the eaves and inside of the home.

Foul Odors

Another telltale sign of a moldy roof is a damp, musty smell. This rancid odor is often the first sign of mold on the premises, even before a homeowner spots the mold growth.

The smell will be more noticeable the closer you come to the moldy shingles. The upper floors of the home, in the attic, and on the roof itself are places where the scent will be strongest.

Leaks

A roof leak can be the result of excessive mold growth. If the mold has had enough nourishment, it can expand to the point that it weakens roof shingles and the structures beneath them, causing water to enter the home. Once water gets in, the potential for further mold growth only increases, so it's important to have roofing leaks repaired as soon as possible.

If any of these signs are present, immediate action will help save your roof and protect your household.
