I couldn't be happier with the job this company did treating the moss on my roof. From start to finish, they were professional, knowledgeable, and courteous. They arrived on time, explained the process clearly, and completed the work efficiently. The roof looks fantastic, and the moss was thoroughly treated without any hassle on my part. They took great care of my property and left everything clean when they were finished. It's clear they take pride in their work and value their customers. I highly recommend this company to anyone needing roof moss treatment. Excellent service, great communication, and outstanding results. Five stars all the way! ⭐⭐⭐⭐⭐

Prompt, pleasant and nice job. The workers were careful with their ladders, with no damage to a carefully kept landscape. The proprietors are a joy to deal with.

About Us

Our Four-Step Process

Heavy moss growth in the keyways of an asphalt shingle roof in Medford, Oregon

1. Inspect & Protect

We inspect the roof and map where the growth is heaviest. Before anything is applied, we pre-wet and cover the landscaping below.

2. Clear the Loose Moss

Remove the loose moss debris by hand, and clear anything that got in the gutters. No harsh scrubbing, no pressure washing, no damage.

3. Apply the Solution

A low-pressure soft-wash application — applied by an ODA-licensed commercial pesticide applicator — kills moss, lichen, and algae at the root.

4. Let Time Finish It

The moss dies within days, and over the following months, normal rainfall carries the dead growth off your roof. No scraping, no shingle damage.

This Is Our Van

Most setups aren’t built for this. Ours is.

  • Metered chemical injection — the mix is measured, not guessed
  • Dedicated manifolds and buffer tanks
  • Strength matched to your roof, not one setting for every house
  • Controlled application — we know where the product goes

Why Moss Is a Problem

The Asphalt Roofing Manufacturers Association (ARMA) warns that moss can cause shingle edges to “lift or curl” and, in severe cases, contribute to roof-deck moisture damage and leaks.

Oregon State University Extension similarly warns that moss can “lift shingles and allow water to penetrate and damage underlying layers.”

Serving Medford and the Rogue Valley

We treat roofs throughout Jackson and Josephine County, including Medford, Ashland, Central Point, Jacksonville, Talent, Phoenix, Eagle Point, White City, Gold Hill, Rogue River, Shady Cove, and Grants Pass.

FAQ

Will the treatment damage my roof?

No. We apply at low pressure, which is what asphalt shingle manufacturers recommend. Pressure washing and scrubbing are what strip granules and shorten roof life.

The moss dies within days and turns brown. Rainfall carries it off over the following two to four months. If you’re expecting a roof that looks new the afternoon we leave, we’re not the right fit — nobody can do that without damaging your shingles.

We control overspray, wet down nearby plants before we start, and neutralize and rinse anything that gets contact. Keep pets indoors during the visit and for a few hours after.

No, as long as we have access to the roof and an outdoor water spigot.

Most Rogue Valley roofs need treatment every three to five years, depending on shade and tree cover. North-facing slopes come back faster.

Every roof is different — pitch, square footage, how much growth. Quotes are free and we’ll give you several options.
