If you live in Northern New Jersey, you may have noticed your roof has patches of green moss or black streaks. Moss and algae thrive in your area, making your roof unattractive with these marks. To restore and maintain your roof’s appearance and reliability, it is crucial you understand why this happens and how to prevent it.​ You may want to consider copper-infused shingles for moss prevention, safeguarding your home investment. 

The Impact of Moss and Algae on Your Roof

It’s critical for homeowners to understand how moss and algae impact their roofs. These aren’t just visual flaws; they actively cause deterioration. Moss’s water-retentive nature leads to trapped moisture, inevitably resulting in leaks and shingle damage. Furthermore, algae’s dark pigmentation absorbs sunlight, which can translate to higher cooling costs in the summer months.

Why Moss and Algae Thrive in Northern New Jersey

Several factors specific to Northern New Jersey contribute to the prevalence of moss and algae on roofs. The region’s abundant rainfall, averaging over 46 inches annually, fosters high humidity throughout the warmer months. Coupled with the shade cast by numerous trees – which inhibits drying – these persistently moist conditions create an environment where moss and algae thrive.

Traditional Methods of Moss and Algae Prevention

When homeowners notice moss or algae on their roof, they may try some of the methods below to combat it. These may be effective, but also have their downsides. Using algae-resistant shingles for moss prevention is a way to avoid the hassle of trying to remove it once their roof has already been damaged.

• Chemicals: Effective at killing growth but may harm roof materials and the environment.
• Manual Removal: Hard work and can damage shingles if not careful.
• Zinc/Copper: Rainwater carries ions from these strips, preventing growth. These solutions often require regular attention and may not be permanent.

The Role of Copper in Modern Shingles

For homeowners seeking effective copper-infused shingles for moss prevention, modern roofing technology offers an innovative solution. Shingles are now developed with copper granules embedded within them. Copper’s natural antimicrobial properties are key to this prevention, inhibiting the growth of moss and algae. When it rains, these copper shingles for moss prevention release copper ions, creating a surface environment that naturally deters these organisms.
