Choose your city
Washington's climate is conducive to organic growth on roofs, particularly moss, which can become quite dense. This moss retains moisture, which can seep under shingles, leading to rot in the underlying wood structure. Algae can also cause discoloration. Our cleaning process utilizes low-pressure washing and eco-friendly solutions designed to eradicate these growths without damaging your shingles or gutters. We pay close attention to areas where debris collects, as these are prime spots for moss to take hold.
Common questions
How often should roofs be cleaned in Washington?
Given the persistent moisture and mild temperatures in areas like Seattle and Kirkland, annual or bi-annual roof cleaning is often beneficial. This helps prevent the buildup of moss and algae that can compromise shingle integrity and lead to moisture-related damage over time.
What is the 25% rule for roofing?
The 25% rule in roofing is a guideline suggesting that if more than 25% of a roof deck needs repair or replacement, it is often more practical and cost-effective to replace the entire roof. This ensures consistent performance and avoids potential issues from mixed-age materials.
What causes moss on roofs in Seattle?
Moss thrives in the damp, shaded conditions common in Seattle and the surrounding areas. The frequent rainfall and often overcast skies provide the consistent moisture moss needs to grow. It attaches to shingles and can hold significant amounts of water, potentially damaging the roof structure.
How much does it cost to have a roof cleaned?
The cost for roof cleaning is influenced by the size of your roof, the type of roofing material, and the degree of moss or algae growth present. Factors such as roof pitch and accessibility also play a role in the final quote. We offer free phone consultations to provide an accurate estimate.
Which company is the best for roof cleaning near me?
When selecting a roof cleaning service, consider providers experienced with Washington's specific climate challenges. A company familiar with preventing moss and algae growth effectively in the Seattle metro area will offer the best approach for long-term roof health.
What is the average cost to have a new roof?
The average cost for a new roof installation varies based on roof dimensions, the complexity of the design, and the materials selected. Additional costs can arise from necessary structural repairs or upgrades to the underlayment. We provide a free phone quote to detail your specific project's cost.
