Expert Asphalt Roof Cleaning Services in Portland

Asphalt roofs are the most common type of roof. They are a reliable and cost-effective way to protect your home. To ensure that your asphalt roof continues to perform its best, especially in the Pacific Northwest where moss grows fast, we recommend periodic cleaning.

What Is an Asphalt Roof?

Also known as a composite roof, an asphalt roof uses layers of shingles to prevent moisture from entering your home. These shingles can be made from various materials and are held together by asphalt, a thick black petroleum-based liquid that’s sticky and waterproof.

Granules are added to the surface of the shingles to prevent them from sticking together and to give them UV protection. Your shingle roof deteriorates over time, especially when moss, and algae take root and damage the surface. Regular upkeep and cleaning will extend your roof’s performance and life.

How Does All Surface Clean Asphalt Roofs?

Asphalt shingles require gentle cleaning to prevent the loss of the protective granules on the surface. The trick is to find the right amount of abrasion to combat moss or algae growth without causing damage.

We treat every roof on an individual basis. It’s what sets us apart from the competition. We always give you an on-site bid so you can be certain the job is being properly handled. We never give general bids by the square foot.

There are four methods we use to clean asphalt roofs, depending on your unique needs:

  1. Standalone treatment
  2. Hand brushing
  3. Soft washing
  4. Low-pressure/high-volume power washing
  5. A combination of any of the above

How Often Should I Have My Asphalt Roof Cleaned?

We recommend somewhere between six months and three years. It depends on the age and condition of your roof as well as the environment you live in.

High moss areas require more frequent care. Applying a moss preventative can help stave off infestation and keep your cleaning costs down.

Your asphalt roof should last 15 to 40 years, depending on how you care for it. Periodic cleaning is a simple low-cost investment proven to prolong your roof’s life.
