Here’s How Algae Affects Your Roof
As roofers serving New England homeowners, we often encounter a common problem that can significantly impact the lifespan and functionality of your roof: moss and algae growth. This common issue often goes unnoticed until it becomes a significant problem, as these seemingly benign organisms can cause substantial damage if left unchecked. Here’s a closer look at how moss and algae affect your roof, especially in New England, and what you can do to protect your home.
The Moss and Algae Problem
1. Understanding Moss and Algae
Moss and algae are two different types of organisms, but they often get lumped together when discussing roof issues. Algae is a blue-green organism that thrives in shaded, moist environments. Moss, on the other hand, can form thick mats on surfaces. Both can cause significant problems when they grow on your roof.
2. How They Affect Your Roof
Shingle Damage: Moss and algae aren’t just unsightly—they can also be damaging. Moss, in particular, retains moisture against your roof’s surface, which can cause asphalt shingles to deteriorate more rapidly. This moisture buildup can lead to the loss of granules on shingles, reducing their effectiveness and shortening your roof’s lifespan.
Structural Issues: As moss and algae grow, they can lift shingles or tiles, creating gaps that allow water to infiltrate your roof. This can lead to leaks and, over time, structural damage to your home.
Aesthetic Concerns: A roof covered in moss or algae can reduce the curb appeal of your home. Algae, especially the blue-green type, can can lead to streaking and discoloration, which may affect the overall appearance of your roof.
Why New England Is Particularly Vulnerable
New England’s climate is a prime environment for moss and algae growth. Our area’s abundant shade from trees, coupled with the high humidity, frequent precipitation, and changing temps, provide ideal conditions for these organisms.
1. Humidity and Moisture
The high humidity levels experienced throughout the year, especially during spring and fall, provide a perfect breeding ground for algae. Moss thrives in the damp conditions typical of New England, which means your roof is at greater risk of infestation.
2. Temperature Variations
New England’s temperature swings between cold winters and warm summers can trap moisture on your roof, further encouraging moss and algae growth. During winter, snow and ice can trap moisture on your roof, creating a perfect breeding ground for moss and algae. When the temperature warms up, the melting snow and ice provide additional moisture, exacerbating the problem.
