About Roof Cleaning Companies in Seattle

Roof cleaning in the Seattle area isn't just a matter of curb appeal, it's an important part of maintaining your roof. Overcast and rainy skies are the norm in the Pacific Northwest, and the limited direct sunlight and volume of rainfall can cause moss growth and tree debris accumulation on roofs. Water damage caused by moss and debris can lead to a host of issues with your home's exterior and interior.

Any damage you notice on your roof should be addressed as soon as possible, but to help prevent your roof system from getting to that point, a professional roof cleaning company can provide services like roof washing, moss removal, moss treatments, and annual cleanings. Some companies offer additional services such as gutter cleaning and yard debris cleanup.

Seattle Roof Cleaning Services

Why you need roof cleaning

In the Pacific Northwest, the combination of rainfall and overcast skies creates conditions that are perfect for moss growth on roofs and excess moisture collection in roofing materials. With such a high annual rainfall average, cloudy skies, and moderate average temperatures for much of the year, roofing doesn't have the time to dry out very well.

To compound the issue, the snow and freezing temperatures in winter can cause the excess moisture from Seattle's rainy season to freeze, expand, and lift up the shingles. Once that happens, there is an open pathway for water to seep under your roof's shingles.

Regular roof cleaning services help prevent problems such as:

  • Shingle deterioration
  • Roof leaks
  • Ice dams
  • Pest infestations
  • Interior water damage

Preventing roof damage from moss, moisture, and debris

Debris from the trees around your house should be cleaned off regularly by a professional. Layers of leaves, pine needles, and sticks can cause water retention and physical damage to the shingles. Keep the trees above your home trimmed to avoid damage from falling pine needles, leaves, or branches.

Annual maintenance can keep the roof clean and damage-free. A roof cleaning professional will assess your roof's need and provide a plan based on your specific issues. Typical roof cleaning services include:

  • Removal of loose debris
  • Moss treatment
  • Moss removal

Depending on the roof cleaning plan you choose as well as the needs of your home, some companies also offer additional services, including:

  • Gutter cleaning
  • Ground debris removal
  • Application of moss-inhibiting treatments

Roof cleaning companies can clean virtually any type of roofing material, but if your roof is in severe disrepair or is made of a delicate material, they may advise you to contact a professional roof replacement contractor instead.
