moss on roofs seattleYour roof does more than just keep the elements out. It helps insulate your home, preventing heat loss in the winter and ensuring cool air stays inside during the summer. Additionally, the roof helps maintain the structural integrity of your property and adds value to your home. For these reasons, it’s important to make sure your roof stays in excellent condition.

A common roofing problem encountered by Renova Exteriors’ team is moss growth. Some people mistakenly believe moss on roofs is harmless and even lends a rustic charm to homes. Unfortunately, left unchecked, moss growth can severely damage roofing and shorten its lifespan.

Read on to learn why moss grows on roofs and what you can do to prevent it.

Why Moss Grows on Roofs

Seattle, WA, experiences frequent rains throughout the year and gets humid in the summer. This makes the area the perfect place for moss, which thrives in damp environments, to thrive.

Additionally, debris buildup on roofs and gutters can cause water to puddle on your roof. The longer the puddles stay on the roof, the higher the likelihood of moss and other vegetation growing on it.

Lack of sunlight also promotes the growth of roof moss. You’ll notice that your roof’s shaded or north-facing sections have a good chance of encouraging moss growth throughout your roofing system.

How Does Moss Affect Your Roof?

The impact of moss on roofs depend on the severity of the problem. One consequence mossy roofs can have on your home is its negative impact on its curb appeal. If you’re looking to sell your home in the near future, a mossy roof will likely drive potential buyers away.

If left untreated, the more serious effects of mossy roofs are exposing your roof to water. If your roofing system is made up of wooden shingles, the damage from prolonged exposure to water can be considerable. The water will cause shingles to break down, which will, in turn, allow water to seep into your ceiling and cause further water damage to your home and its contents.

How to Prevent Moss From Growing on Your Roof

To prevent moss growth on roofing, regularly clear gutters of dead leaves, branches, and other debris. Also consider trimming tree branches near your roof, and check the downspouts to ensure they’re working properly.
