How to Remove Moss From a Roof With Detergent


A roof that is covered in moss is more than just an eyesore; it also poses a risk to the integrity of the roof and the rest of the house. Vinegar can be used to kill moss, which is one method for removing it from your roof; however, there are other methods as well. Due to the fact that moss is slippery and working on a roof comes with its own set of inherent risks, you should approach any repair of this nature with extreme caution.

Problems With Moss

Moss sends its roots deep into and under your roofing shingles, where it eventually grows between them and pushes other shingles out of place, which ultimately results in leaks. In addition to this, as the staff at Expert Home Report explains, moss has a natural dampness to it. [Citation needed] The sponge-like surface of moss is able to retain a significant amount of water, which allows it to thrive in environments that are dark, cool, and damp. Moss both feeds on and encourages rot, which occurs as a result of the accumulation of more moisture.

If you do nothing, the water damage caused by these leaks will cause mould and rot in the wooden structure of your home, and the openings in your roof may even attract insects and rodents. If you do nothing, these problems will get worse. In a nutshell, moss should unquestionably be regarded as an imminent danger to both your roof and your home.

It is possible to kill and remove moss yourself by using a variety of home remedies and plenty of elbow grease, but as the moss advances, the difficulty and danger of attempting to remove it yourself increases exponentially. Additionally, climbing on your roof presents its own set of inherent risks to your safety.

Washing Powder to Kill Moss

The widespread belief is that the moss can be eradicated by sprinkling powdered laundry detergent all over the area where it is located. After that, you may save money on costly expert services by simply spraying or scrubbing the shingles to remove any dead moss that has accumulated there.

It has been confirmed by professionals from Roof Life of Oregon that it is technically true that detergents that are readily accessible would destroy moss. In addition, they state that it is possible to physically remove the treated moss that has died by either spraying it with a high-pressure hose or washing and scraping it, despite the fact that this procedure is more difficult and costly than it may first seem. To eradicate moss, an unexpectedly high concentration of detergent is required.

The price of a pressure washer or any other kind of high-pressure hose is another factor that contributes to the overall cost of such a job. In addition, improper usage of such a forceful stream of water might result in damage to the roof, the repair of which would be rather expensive.

Dangers and Complications

Because moss is capable of retaining a significant amount of water, as soon as detergent comes into touch with it, the surface of the moss, which was previously slippery, will become sticky. When this happens, the risk of being hurt if you step on it or are beside it significantly rises. When people try to remove roof moss on their own, they often end up injuring themselves seriously or even losing their lives.

Even if you are able to reach the moss from a ladder without having to step on the roof, there are other considerations to take into account. These include the toxic nature of the detergent and its impact on plants that are located below or near the roof, as well as the impact that the detergent has on your roof and at the end of your downspout.

Detergent is also a degreaser, which means that it may remove the asphalt, tar, and oil that are protecting your shingles and providing a waterproof surface on your roof. This can be accomplished by washing your roof with detergent. The authors at Keeping It Clean believe that doing this may cut the lifetime of your shingles by as much as half, which would defeat the objective of removing the moss from the roof. If you were to wait for the rain to wash away the detergent instead of hosing it off yourself, the intervening time would enable the detergent to further breakdown those compounds. This would be the case since the rain would wash away the detergent.

DIY Alternatives for Moss Removal

There are several approaches that have been investigated to eradicate moss and remove it from a variety of surfaces, and each of these approaches comes with its own set of limitations. The employees at Infinite Roofing say that it may take a few days for vinegar to destroy moss and lichen. After that amount of time has passed, you may remove the dead moss using a scrubbing brush or a broom. According to Roof Life of Oregon, vinegar has a fragrance that lingers after it has been used.

According to Garden Guides, the use of vinegar containing between 4 and 8 percent acetic acid is successful in destroying moss, even when applied to concrete and tile; however, it will also kill other types of plants. Copper sulphate, in addition to being an efficient moss killer, is also non-toxic to the majority of plant species. It leaves a stain not just on porous surfaces but also on skin, clothing, and plants, and it also elevates the soil’s acidity level.

Bleach has the same or even more cleaning power as detergent. Naturally, it will alter the hue of whatever surface it comes in contact with. As with detergent, it also has the negative effects of being poisonous and a degreaser. There are numerous more do-it-yourself solutions, as well as moss killers that can be purchased in stores; but, the potential remains a dangerous one when compared to the possibility that professional services may safely and efficiently remove the moss from your roof.
