Roof Moss Removal 101

We often receive questions regarding proper roof moss removal steps. While we do not endorse climbing on your roof as it can negatively impact your roof warranty, there are several preventative steps that homeowners can take to prevent serious issues from arising. For note, in most cases, severe roof moss can signify serious roof issues and roof moss removal is not advised. This is the case where serious repairs or replacement are in order. Small areas of light moss can and should be removed to best ensure a long lifespan of your roof. Roof moss is primarily caused by water shed issues on your roofing system. When this water holds for long periods of time, moss has the perfect environment for growth. In regard to proper roof moss removal, it is highly recommended to engage in adequate spring and fall cleanup (insert post) to stop moss in its tracks. If you notice early moss growth, add it to these routines to best stay on top of your roof’s health.

So, what exactly can be done to remove non-intrusive areas of moss growth? Again, we do not condone climbing on your roof yourself, but there are several steps that can be taken from the ground and a ladder that can either reduce or completely remove roof moss. It is important to treat moss early before it begins to degrade your shingles which opens your roof up to a host of other problems, most importantly, leaks.

Rinse Your Roof

Properly rinsing your roof is an important first step in quickly and efficiently treating roof moss. Note we say rinse, not pressure wash. Pressure washing your roof is not advised as it can weaken and damage shingles, and effectively void your roof warranty. A light to moderate rinse can help loosen adhesions and aid in roof moss removal. Homeowners may be able to stop at this step if the moss is light.

Consider Scrubbing From the Ground

A light bristle brush on the end of a long pole is a fantastic resource for weakening roof moss adhesions. Much like pressure washing, it is ill-advised to use something with a strong bristle as this can also weaken or damage your shingles. In most cases, a light bristle is all that is needed to agitate the moss enough that it will fall off of your roof. One thing to keep in mind here is to be extremely gentle. If the moss cannot be scrubbed this way, this is an indicator that the growth is worse than it looks and proper roof moss removal may not be possible by yourself.

Roof Moss Removal Chemicals

Several companies offer gentle chemicals that help with killing roof moss and aid in its removal. Like with any chemicals, these are strong manufactured substances that can do more harm than good in the long run. For example, most plumbers do not recommend chemical solutions to clear clogs because the solution erodes the drains. If you choose to work with a chemical solutions, conduct proper due diligence and ensure the chemicals are gentle enough not to damage your shingles. However, much like in home cleansers, diluted vinegar can be a light duty moss remover that does not harm the roof or the environment. There are countless online resources to the ratio for this.

In all, we do not exactly recommend DIY roof moss removal as there are many things that can go wrong and you open your roof for possible damage.
