Roof cleaning can be as simple as clearing debris from your roof with a leaf blower, or as involved as doing a full on moss removal project. Either way, you and your roof will be much happier after an encounter with Seattle Gutter Cleaning LLC.

Moss Removal & Treatment

There are a lot of myths and unanswered questions out there about rooftop moss. Let's make it simple and try to make some sense out of it.

Moss destroys your roof in two ways. The roots (called rhizoids) work their way into your roof, separating and eating away at the shingles, and, in the worst cases, the wooden support structure of your roof. Secondly, moss holds moisture like a sponge that never dries. The water stored in your moss causes the wood and shingles on your roof to literally rot.

It's best to catch moss early on and to prevent it from coming back.

Seattle Gutter Cleaning LLC removes moss from your roof by hand with a set of stiff bristled brooms, brushes and rakes. Then, we apply a zinc-based mineral compound that kills any remaining moss particles and spores. The treatment changes the ph level of the roof, neutralizing the roof and making it difficult for the moss to grow back. It is a tried and true method, and it is the safest most effective way possible to remove rooftop moss.

You will be surprised at how cost effective it can be. Especially when it could double, or triple, the life of your roof. It's almost a no-brainer.

Moss Packages

For the convenience of our customers, Seattle Gutter Cleaning LLC offers three different moss packages. The Treatment Package is for clients that have very new moss growth (tiny moss that only began growing within the past year or less), want to take preventative measures against moss, or are on a very tight budget. The Chickadee Package is for customers with a small amount of moss, a smaller home, or customers that are more interested in functionality of the job and budget than getting a cosmetically perfect job done. The Osprey Package is for customers with a significant amount of moss, a larger sized home, or customers that are concerned with the cosmetic appearance of the roof (no visible dead moss after the job). This service is also available on an hourly basis, but most of our clients find the packages to be more reasonably priced and are able to identify the package that is right for them.

Moss Removal FAQ

What about pressure washing my roof?

There are companies that do it, but I think it's a bad idea. Pressure washers operate at extremely high power, and can destroy the integrity of your roof. Removing moss by hand is just as effective, more economical, and the recommended technique for roof cleaning. It just makes more sense.

How long does the moss treatment last?

It completely depends on the house and the environment. Moss thrives in dark damp places. If your house is shaded by trees and your roof collects debris, you can expect moss on the roof and the treatment will last for a limited amount of time. If your house receives full sun, you are much less likely to experience moss, and the treatment will be effective for a longer period of time. Essentially our treatment brings your roof back to ground zero, so if it took 5 years for the moss to grow in the first place you can expect it to take 5 years or less for the moss to return.

What are the environmental impacts?

At Seattle Gutter Cleaning LLC, we have done extensive research and testing with all the different rooftop moss treatments available on the market today, including surveying the environmental impacts. We strive to offer our clients the best, effective most treatment in an environmentally friendly way has proven to be a challenge. We encourage our clients to read up, do their homework and call us with questions.

What about unconventional moss treatments?

We do not deal with the unconventional, we only use tried and true methods. Home remedies such as applying bleach, laundry soap, vinegar or lemon juice may or may not kill moss and can be detrimental to the roof. These solutions can be particularly damaging to the tar that binds together the shingles of most composition roofs, and using home remedies to kill moss on your roof will definitely void your roof warranty.
