Over the course of the lifetime of a roof, mold is likely to grow on the shingles at some point. The combination of moisture and sunlight makes a roof the perfect place for mold. When left on your roof, mold can wreak havoc and cause significant damage that can require the services of a roofing contractor in South Jersey.

In order to protect your roof, you need to first understand how mold impacts your roof.


The most obvious impact of mold is on the look of your home. The roof is one of the most recognizable elements on your home and plays a major role in the curb appeal. Having green moss covering your roof can decrease curb appeal and the overall value of your home if you decide to sell.

Compromised Shingles

Mold is most likely to negatively impact the shingles on your roof, as that is what the moss attaches too. Your shingles can begin to deteriorate, which can leave your home exposed to the elements. The longer moss is left untreated, the more it is able to spread. As it continues to spread over your roof, the more damage it does to your shingles, which provides more opportunities for moisture to penetrate your home.

Poor Air Quality

Studies show that moss on the roof is able to infiltrate the home and decrease air quality. The increase in moisture from the moss in your home can leave a mildew smell inside your home. It can also increase allergy symptoms, including respiratory problems, throat irritation and nasal stuffiness.

Structural Damage

Moss can also begin to grow on the wood structural elements of your home from your roof. Once the moss moves through the shingles, it can grow into the wood. While rotting shingles can damage your roof, rotting wood beams can compromise the entire structure of your home. When left untreated, your home can literally begin to fall apart.

If you notice moss beginning to grow on your roof, you should contact a professional roofing contractor in South Jersey. When removed quickly, the moss will not be able to spread and cause damage. A roofing contractor will be able to inspect for any possible damage and ensure your roof remains safe and intact.
