Roof Cleaning Options

Most homes in the Pacific Northwest should have their roof checked and maintained annually. Moss removal and algae prevention are key factors in shingle and roof health. For most Puget Sound homes we typically recommend our Standard Program: a Valentine Roofing technician comes out once each year to ensure your roof is always in good condition. For those homes with excessive tree cover or that are in areas with high wind gusts and are subject to heavier storm damage, we recommend our Deluxe Program.

A roofing technician will be out semi-annually with our Deluxe Program for roof cleaning and to inspect your roof, ensuring that your roof is clear of debris and in good shape year-round, even after a big storm. If you are looking to sell your home or just want your shingles to look new again, a onetime roof cleaning is a great and affordable way to enhance your home’s beauty.

Frequently Asked 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 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 will ensure they stay gone.


How much does a roof cleaning cost?

The cost of a roof cleaning will vary depending on the type of roofing material as well as the size and pitch of the roof. A roofing contractor that is licensed, bonded, and insured will likely charge in the mid-hundreds for most roof cleaning. At Valentine Roofing a onetime 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 helping the process. The rain will bring the treatment down the roof covering the shingles as the treatment mixes with rainwater. This is an effective way to guarantee that all your shingles get an even distribution of treatment and provide weeks of treatment ensuring any remaining moss is killed.
