Features and Benefits of Roof Cleaning

  • Moss & algae removal: In Seattle, moss and algae can start growing on just about any surface, especially your roof. If left unchecked, moss and other organic material can cause real damage to your shingles. Prevent moss roots from causing shingles to lift while avoiding shingle decomposition caused by algae and bacteria. Elongate the life of your roof with a roof cleaning and moss removal service today.
  • Gutter cleaning: Clearing downspouts and gutters will prevent the backflow of water onto your roof, which can overflow onto your home’s siding and foundation. Roof drain cleaning service will effectively safeguard against roof leaks, soil erosion, and siding damage. Protect your investment with a gutter cleaning from Valentine Roofing.
  • Increase curb appeal: Real estate professionals agree that curb appeal is a major factor when selling a home. Having a show-worthy roof gives potential home buyers confidence in the durability of your home. Elevate your home's curb appeal with a roof cleaning by Valentine Roofing.
  • Before-and-after photos: Most homeowners can't see the top of their roof, so how do they know that the moss was removed, or that the gutters were cleared? Valentine Roofing solves this problem by providing before-and-after photos with every roof cleaning service. We are always proud to show homeowners our work!

I get annual roof cleanings since Valentine Roofing installed my new roof and gutters several years ago. As usual technician texted 30 minutes before arrival so we had a heads up. Roof and gutters were cleaned for a reasonable price. He cleaned up afterward around the exterior of the house where debris had fallen from the roof. Hard to expect anything more. Thanks!

Frequently Asked Roof Washing Questions

Should I have my roof pressure washed?

Pressure washing is never recommended for cleaning your roof. Shingle manufacturers specifically indicate that pressure should never be used to clean your shingles. Pressure washing does not kill algae and, if left untreated, the moss and algae will return quickly to your roof. You also run the risk of causing irreparable damage to the shingles themselves. Pressure washing will loosen granules which can cause shingles to prematurely fail. The water pressure can also lift shingles, breaking the seal between shingles and allowing a path for future leaks.

Valentine Roofing always recommends moss removal by gentle agitation using a roof brush to prevent granule loss and shingle lift, followed by a moss and algae treatment to ensure they stay gone.

How much does a roof cleaning cost?

Roof cleaning cost will vary depending on the type of roofing material as well as the size and pitch of the roof. At Valentine Roofing a one-time roof cleaning starts at $549, while our annual roof cleaning and maintenance starts at $329, a great value.

Can I perform a roof cleaning myself?

A roofing contractor familiar with the roofing material and manufacturer recommendations, like Valentine Roofing, is always the best choice when it comes to roof cleaning and moss removal. You can rest assured that a roofing contractor will have the proper equipment, training, and tools to safely and effectively clean your roof.

Does rain wash away the moss and algae treatment on my roof?

While it may seem that the rain is washing away any treatment left on your roof to kill moss and algae, it is actually helping the process. The rain will create a mixture with the treatment, covering the shingles as it moves down the roof. This is an effective way to guarantee that all your shingles get an even distribution of treatment for weeks to come.
