4 Issues That Arise From Mold On Your Roof

April 11, 2020

Mold is one of the many hazards that homeowners need to be watching out for. Most think about mold that can develop on the interior of their home on ceilings and around windows. However, mold can be just as damaging to your roof.

Appearance And Perceived Value

Mold is very easy to spot, especially against the darker tone of roof shingles. It can turn a sleek looking roof into a perceived nightmare. It’s very difficult to have any sort of powerful curb appeal when your roof has mold growing on it. As soon as you notice dark spots, you need to get them cleaned up quickly. This will ensure that your home’s value doesn’t decrease due to visible mold.

Air Quality

Even though the mold is growing on the exterior of your home, it’s connected to the interior. Mold spores will keep the roof in a somewhat damper environment that fosters more mold growth. This puts off a mildew smell that is extremely unpleasant. These mold spores can be a big contributor to the poor air quality inside of your home. Poor air quality leads to respiratory and other allergy-related conditions.

Shingle Damage

Any good residential roofing company will tell you that shingle damage will happen if you let mold grow on your roof. The combination of bacteria and moisture starts to decay the shingles. Given enough time without intervention, the mold will make your shingles more vulnerable to pest destruction and water infiltration. Remember that your roof is the layer that protects you from the outside environment. When the roof is not doing its job properly, it can lead to massive damage throughout the interior of your home.

Higher Energy Costs

When mold is allowed to grow in patches on your roof, it will change the environment in that section of the roof. The mold will formulate a dark spot that absorbs more sunlight that unmolded shingles. This higher level of sunlight absorption will lead to a hotter roof on your home. When your roof absorbs heat, it causes your air conditioner to work harder to cool your home to the desired temperature. Therefore, you’ll notice an increase in your energy costs when you have mold growing on your roof in the hot summer months.

Understanding how mold affects your roof can help you to learn the importance of dealing with it when you first notice there’s a problem. In most cases, you can easily clean the mold off of your roof. If you notice there is any significant damage to your shingles, it’s best to call in a roofing professional to replace them.
