Moss and algae can deteriorate shingles, reduce your roof’s lifespan, and even impact energy efficiency by trapping moisture and causing leaks.
– Tony Tomasone, Sales Manager
As the weather cools and fall brings more rain, moss and algae on your roof can become a real issue.
Moss thrives in damp, shaded areas, while algae tends to develop on roofs that retain moisture, especially in humid climates.
When left untreated, both can deteriorate shingles, reduce your roof’s lifespan, and even impact energy efficiency by trapping moisture and causing leaks. Fall is an ideal time to address these problems because cooler, wetter weather can accelerate their growth, making prompt action essential.
Moss and algae are just one part of a bigger picture of gradual wear that roof rejuvenation is designed to address.Moss and algae not only create an unsightly appearance but can also lift shingles over time, allowing water to seep underneath. This can lead to mold growth and costly structural damage if not treated. Fortunately, there are solutions. At RAW Roofing Solutions, we recommend a comprehensive roof inspection in the fall to assess the extent of moss and algae growth. Our treatment options include environmentally safe cleaners that eliminate growth without harming your roofing materials.
Preventative strategies are equally important. After treatment, installing zinc or copper strips along the roof’s ridge can inhibit future growth since rainwater activates these metals, creating a surface moss and algae can’t adhere to. Additionally, trimming back overhanging branches allows more sunlight onto the roof, reducing moisture buildup. Shade from mature trees makes this a frequent issue on wooded lots, so we check for it during every roof inspection in Gates Mills.
If your roof is already showing signs of drying out alongside this growth, our Roof Rejuvenation guide covers how to restore it before those problems compound.
