Moss on Roofs: Risks and Removal in Kirkland, WA
Jen Woslager • February 21, 2025
The dangers moss poses to roofs in Kirkland, WA, and why professional cleaning or replacement by Washington Roofing Services is essential.
In the city of Kirkland, WA, moss growing on rooftops is a frequent sight. However, despite its seemingly harmless appearance, this green layer can pose significant risks to the structural integrity of roofing structures. At Washington Roofing Services, we emphasize the importance of understanding these risks and advocate for professional intervention, either through roof cleaning or replacement, to safeguard your home.
The Risks of Moss Accumulation
1. Moisture Retention:
Moss retains moisture directly against the roof surface, which can severely damage the roofing materials over time. This is particularly problematic during Kirkland's rainy seasons, as it accelerates wear and can lead to leaks and rot in the roofing structure.
2. Root Damage:
Moss has rhizoids (root-like structures) that can embed themselves in and lift shingles, disrupting the roof’s waterproofing integrity and making it susceptible to wind and rain infiltration.
3. Blocked Drainage:
Thick moss growth can impede water runoff, leading to pooling and increased pressure on the roof structure. This stagnation can cause leaks and contribute to structural decay, particularly in the valleys and dips of the roof.
4. Reduced Energy Efficiency:
By keeping the roofing materials damp, moss can decrease the effectiveness of roof insulation, leading to higher heating costs and decreased comfort levels inside the home.
Why Professional Roof Cleaning or Replacement?
Preventative Maintenance: Regular inspections and maintenance by professionals can prevent moss from taking root. Washington Roofing Services recommends annual checks, especially after the wet season, to catch and address any moss growth early.
Effective Cleaning Techniques: Professional roof cleaning involves techniques such as soft washing, which removes moss without damaging the underlying roofing materials. This method is effective in not only removing visible moss but also in killing spores that can lead to future growth.
Long-Term Solutions:
In cases where moss has caused irreparable damage, a roof replacement may be necessary. We provide expert assessments to determine if a replacement is more cost-effective than ongoing repairs.
