We recently completed a roof cleaning project in Surrey, addressing a heavily moss-covered and mold-stained asphalt shingle roof. Our team took a meticulous approach, carefully removing the moss to avoid any damage to the shingles. Once the moss was cleared, we thoroughly cleaned the roof and ensured the gutters were free of debris for proper water drainage. To finish, we applied a specially formulated treatment to eliminate any remaining organic growth and provide protection against moss regrowth for up to two years.

This process not only rejuvenated the roof’s appearance but also safeguarded its integrity, helping to extend its lifespan. Moss and mold on asphalt shingles can significantly compromise their durability by trapping moisture and causing premature wear. Our cleaning method ensured that the roof was both aesthetically refreshed and functionally restored.

The Risks of Moss and Black Mold on Asphalt Roofs

Moss and mold may seem like minor nuisances, but they can cause serious long-term damage to asphalt roofs:

• Moss Damage: Moss anchors itself to shingle surfaces, growing between layers and lifting shingles. This creates pathways for water infiltration, increasing the likelihood of leaks and water damage.
• Black Mold: Mold traps heat on the roof’s surface, reducing energy efficiency and raising cooling costs. Over time, this added strain can wear down the roof and its components.

Without regular maintenance, these issues can escalate, leading to costly repairs or even a full roof replacement.
