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.

Hailstorms can be a homeowner's worst nightmare, leaving behind hidden roof damage that might not be noticeable at first glance. If you've recently experienced a storm, you might be wondering: What does hail damage look like on a roof? Recognizing the warning signs early can save you from costly repairs down the road. At Washington Roofing, we help homeowners assess and address hail damage before it turns into a major issue. In this guide, we’ll walk you through the telltale signs of hail damage, how to handle insurance claims, and when it’s time to consider roof replacement. Understanding Hail Damage: What to Look For Hail comes in various sizes, and even small hailstones can cause significant damage to your roof. The extent of the damage depends on the size, speed, and density of the hail, as well as the age and condition of your roof. Washington Roofing recommends inspecting your roof after every major storm to identify any visible signs of wear and tear. Common signs of hail damage include: Dents in shingles that compromise their protective layer Bruising (soft spots on asphalt shingles that indicate underlying damage) Granule loss, which weakens the shingles and exposes the roof to further weather-related deterioration Cracks or splits in wood or slate roofing materials Dents in metal roofing, which can affect both durability and appearance The Impact of Hail on Different Roofing Materials Not all roofs react to hail damage in the same way. Different materials have varying levels of resistance: Asphalt Shingles – The most common roofing material, asphalt shingles are prone to bruising, granule loss, and cracks. Metal Roofs – While metal roofing is durable, it can still sustain dents in severe storms. Slate & Tile Roofs – These materials can crack under the impact of large hailstones. Wood Shake Roofs – Hail can split wood shakes, leading to moisture penetration and rot. At Washington Roofing, we specialize in repairing and replacing all types of roofing materials, ensuring your home remains protected after a storm. How Hail Damage Can Lead to Bigger Problems Ignoring hail damage can result in more serious issues for your home. Over time, damaged shingles can allow water to seep in, leading to: Leaks and water damage inside your home Mold growth due to trapped moisture Structural weakening of your roofing system If you suspect hail damage, it's crucial to contact a professional roofing company like Washington Roofing to assess the extent of the issue and recommend appropriate solutions. How to Spot Hail Damage on Your Roof If you’re wondering what does hail damage look like on a roof?, here are some easy ways to check: Inspect Your Gutters – If you notice excessive granules from your shingles in the gutters, your roof may have suffered damage. Check for Dents in Metal Surfaces – Look at vents, flashing, and gutters for signs of impact. Examine Your Attic for Leaks – Any unexpected water stains could indicate roof damage. Walk Around Your Property – Damaged siding, outdoor furniture, or vehicles may be a sign that your roof was also affected. For a thorough inspection, trust Washington Roofing to provide expert assessments and recommendations. Does Homeowners Insurance Cover Hail Damage? One of the biggest concerns for homeowners is whether their insurance will cover hail damage repairs. Most policies do include coverage for hail-related roof damage, but there are some factors to consider: Your deductible – The amount you must pay before insurance kicks in The age of your roof – Older roofs may have limited coverage Policy exclusions – Some policies exclude cosmetic damage, even if it affects the roof’s lifespan At Washington Roofing, we work with homeowners to navigate the claim process, ensuring they get the coverage they deserve.
