The Moss Challenge in the Pacific Northwest

In Oregon, moss isn’t just a cosmetic issue—it’s a direct threat to the lifespan of your asphalt shingles. Moss thrives in our damp, shaded environment, and if left unaddressed, it can destroy a roof in a matter of years. At Buzzline Roofing, we specialize in professional moss prevention and removal strategies that protect your investment without damaging your shingles.


How Moss Destroys Asphalt Shingles

Moss is highly absorbent and acts like a sponge, keeping your shingles constantly wet. This moisture leads to several critical problems:

  • Shingle Lifting: As moss grows under the edges of shingles, it lifts them up, creating entry points for wind-driven rain.
  • Granule Loss: The root-like structures of moss (rhizoids) attach to the ceramic granules, pulling them away and exposing the underlying asphalt to UV damage.
  • Rot: Constant moisture leads to the decay of the shingles and, eventually, the roof decking underneath.


The Buzzline Standard for Moss Management

We never use pressure washers. The high-pressure stream of water is the fastest way to strip the granules off your shingles and void your manufacturer’s warranty. Instead, we use a professional, multi-step approach:

  1. Manual Removal: Carefully clearing large moss growth by hand.
  2. Copper Cat® System Installation: We exclusively install the Copper Cat® Moss Prevention System. These specialized copper strips are installed at the roof peaks. When it rains, metallic ions wash down the roof, creating a natural environment where moss cannot grow. Unlike temporary zinc strips, Copper Cat® provides a permanent, professional-grade solution.
  3. Professional Technical Treatments: Applying specialized, eco-friendly solutions that kill remaining spores and prevent regrowth without compromising the integrity of your asphalt shingles.


"Moss management is essential for roof longevity in Oregon. We lead with technical solutions like Copper Cat® because we believe in providing a permanent defense, not just a temporary patch. It’s about professional care for your home’s primary defense."
