A clean roof boosts a home’s curb appeal and value, while algae, moss, and lichen can cause serious damage. These growths not only make the roof look unsightly but can shorten its lifespan and increase maintenance costs. The key to prevention is managing moisture and organic debris on the roof.
How Algae, Lichen, and Moss Damage Roofs
Algae creates streaks that lead to lichen, a harmful organism that erodes shingles, traps moisture, and accelerates wear. Lichen also weakens shingles, making them vulnerable to cracking and sun damage. Moss grows quickly in shady areas, retaining moisture and lifting shingles, which can lead to leaks and wind damage.
Preventing Growth
To stop algae, lichen, and moss, choose algae-resistant shingles and consider adding metal strips along the ridge to help prevent growth. Regularly remove debris and clean the roof to avoid buildup. If growth occurs, chemical treatments can help, but it’s safest to hire professionals to handle the job.
Conclusion
Routine roof maintenance can prevent costly damage and extend your roof’s lifespan. A little care now saves big repairs later.
