Moss is a stubborn type of plant capable of growing on all kinds of surfaces, from tree trunks to rocks. In fact, it doesn’t even need soil! Because of this, you may find moss growth on your roof. This common issue can lead to roof damage, moisture retention, a shorter roof lifespan, and reduced curb appeal.
At Kanga Roof, we understand that prevention is the best cure. It’s much better to act proactively when it comes to moss growth on your roof, preventing this problem from occurring in the first place. That’s why we’re presenting our expert tips for preventing moss growth on your roof and what you should do if it’s already present.
Why Moss Grows on Roofs
First, let’s go over why moss grows on roofs. Depending on the climate, your roof may be moist, dry, shady, or sunny. No matter what the specific conditions on your roof are, there’s likely a type of moss that will thrive in them. However, moss growth is most common on north-facing slopes and under overhanging trees.
Because moss is a non-vascular plant, it absorbs water through its leaves instead of its roots. This means it doesn’t need soil to grow, so your roof is prime real estate. It reproduces through spores, which can be easily carried by the wind and land on the roof, eventually leading to moss growth.
Why You Should Prevent Moss Growth
So, why should you prevent moss growth on your roof? The biggest reason is that over time, moss can damage your roof by lifting shingles and trapping moisture. This comes with a significant risk of leaks and structural damage, along with the potential for mold and mildew growth.
Not only can moss growth damage your roof, but it can also decrease your home’s curb appeal and value. Homes with moss on the roof may look ill-maintained, making them less attractive to potential buyers.
Preventative Maintenance Tips
Now that you know the basics of how moss growth happens and why you should prevent it, let’s get into some preventative maintenance tips.
Keep Your Roof Clean
Remove debris like leaves and twigs from your roof regularly, and clean your gutters to prevent water backup and overflows. This makes the environment less appealing to moss and removes spores before they have the chance to grow.
Trim Nearby Trees
If the type of moss on your roof prefers shade, trim the nearby trees to reduce shade and increase sunlight exposure. Not only does this help prevent moss growth, but it also prevents fallen branches and debris from accumulating on the roof.
Ensure Proper Roof Drainage
Ensuring proper roof drainage is another important aspect of preventing moss growth on your roof. Regularly check downspouts and gutters for clogs, and address any pooling water or drainage issues as soon as possible.
Long-Term Moss Prevention Solutions
There are also long-term solutions designed to prevent moss growth on your roof, including zinc or copper strips. When you install these metal strips along the ridge line, they release ions that kill moss, algae, and lichen. If you’re building a new home or replacing your roof, consider opting for moss-resistant roofing materials, such as asphalt shingles with built-in algae and moss resistance.
Professional Cleaning and Treatment Options
If moss has infiltrated your roof, it’s important to hire a professional to remove it. DIY attempts can accidentally damage certain materials and may be less effective. Plus, they have access to professional-grade, roof-safe moss control treatments.
However, when you’re seeking professional roof cleaning services, make sure you find a company that offers soft washing rather than pressure washing. For more information about why this is so essential, check out our previous blog post, “Will Pressure Washing Damage My Roof?”
