Moss growth is typical on rooftops because winds spread spores, and roof surfaces are humid, providing a favorable growing environment. While small moss colonies may seem harmless initially, they have a detrimental impact on your roof’s structural integrity and longevity. As summer approaches, homeowners should prioritize de-mossing their roofs before fall and winter rains.

Like roof cleaning, roof de-mossing appears simple but a challenging task. Unless you are a roofing expert, this task is best done by roof cleaning professionals. Below are a few benefits of de-mossing your roof.

1. Protects the roof structure and prolongs its lifespan

Roofs are crucial to any building as they form an external protective layer, and they should remain strong to withstand various harsh elements. Unfortunately, while different roofing materials are designed to last more than 10 years, they can easily get damaged, necessitating urgent repairs or a complete replacement, which can get quite costly ( Visit this website to get a quote for your roof repair cost estimate.)

Moss growth on your roof surface quickly spreads and adapts into fissures, slowly forming small cracks between tiles or roof shingles. Once inside the fissures, the growing moss traps moisture, which is detrimental to the roof. Trapped moisture is especially harmful to the roof during winter because it freezes and expands, damaging the roof structure. You should remove moss immediately after you identify signs of growth. This prevents your tiles from structural damage and prolongs the roof’s lifespan.

2. Improves curb appeal

Moss growth on the roof is unsightly and gives the impression of a neglected home. Moss growth also causes decay and degradation, negatively affecting your home’s appearance. Removing moss growth from the roof surface eliminates the unsightly growth, improving your home’s appearance. It also prevents moisture damage and slows structural roof degradation.

3. Protects your family and saves time and money

Most homeowners don’t know the potential effects of moss on their family’s health. While moss is typically safe, it creates favorable conditions for mold growth. The warm, humid, and dark environment created by moss under roof shingles or tiles highly favors mold growth.

De-mossing your home immediately is the best way to prevent mold growth on your roof, while also saving time and costs in the long run in the following ways:

  • Reduces dampness, which improves your home’s energy efficiency
  • Ensures uninterrupted rainwater runoff, which saves on the costs of water damage repairs
  • Improves curb appeal and property value, in case you want to sell or sublet your home
  • Reduces roof deterioration rates and prolongs its lifespan. This saves on the costs of early roof replacement
  • Timely de-mossing saves time and money that would be spent later on moss removal


Homeowners should schedule roof de-mossing immediately after they notice signs of moss growing on their roofs. Moss growth is detrimental to roofing materials and structure. If left unchecked, moss also clogs gutters, attracts pests, causes leaks, and promotes mold growth. While you can DIY moss removal, you should avoid it if you don’t have the right equipment and experience and contact Nashville Roof & Cleaning Pressure Washing.
