How To Eliminate Rooftop Moss


Moss lives in damp environments, which is why it’s typically found in forests, swamps, and other wet areas. While moss can be attractive in certain situations, it’s not becoming when it grows on the roof. To get rid of moss, it must be killed and removed promptly. Below are some tips on achieving moss and mould removal in NZ.

Understand the Need for Moss Removal

Moss can cause severe problems when it grows on a roof. As it thickens, it can lift shingles and allow water or wind to damage the roof. However, it can do much more. Moss can catch insects and debris, which can cause additional water issues. Finally, moss growth can cause shingles to deteriorate over time.

Eliminating Rooftop Moss

Moss can be attractive, but it should be eliminated when it’s on the roof. There are several ways to remove rooftop moss.

  • Brush it off. A brush can make short work of simple moss problems. Use it to dislodge and remove the moss, but use it gently to prevent roof damage. Once that’s done, use a special moss removing cleanser according to the package directions.
  • Try a moss killer liquid concentrate. This works quickly to eliminate moss on the roof, and the ammoniated soap can last for up to a year. Once moss is dead, simply brush it away.
  • Use hot water and salt. For a natural approach, sea salt and hot water can quickly kill moss. Use a spray bottle for application, allow it to soak for about 20 minutes and scrub away the moss. This method may require several applications for the best results.
  • Zinc-containing products. These roof moss killer products are an easy way to get rid of moss. A zinc strip at the rooftop can create an alkaline condition that quickly kills moss. Alternatively, products containing zinc sulphate or zinc chloride can solve the problem almost immediately.

Moss and mould removal in NZ should be handled immediately to prevent further growth and eventual roof damage. Spores can travel a significant distance before settling on the roof, and gutters should be kept as clear as possible for this and other reasons.

Finding the Right Moss and Mould Killer to Use Around Your New Zealand Home


Many homeowners find they have a problem with moss on their lawn or roof and wonder how to go about removing it. The problem is that moss isn’t a problem by itself but a sign that there is an underlying issue encouraging its growth. Homeowners must recognize this basic fact if they wish to eliminate the issue and ensure it doesn’t return.

Why Does Moss Grow In Certain Areas?

When a homeowner looks at their roof and sees moss, it likely means the local weather conditions are damp and the roof is significantly shaded. This vegetation doesn’t develop roots, thus no soil is needed. Moss grows on lawns for these and other reasons. The growth may be associated with excessive shade or it may be a matter of poor drainage. In addition, when the soil has a low pH level or is lacking in certain nutrients, moss may grow.

Removing The Moss

To prevent and eliminate moss growth on roofs, the rooftop needs to be free of any branches and leaves. These organic materials, when allowed to accumulate on the roof, help to hold moisture in, and this encourages moss growth. In addition, any shade prevents the sun from drying these materials. For this reason, it’s best to cut trees back to allow the roof to receive full sun during the day. Moss and mould killer products will be needed to remove any moss that remains.

When it comes to moss growing in one’s lawn, detaching may be enough to eliminate the current growth. NZ moss removal products will be of help in resolving the issue also, but it must be determined why the moss grew in the first place, which involves figuring out where the problem lies. If this step isn’t taken, the moss will return in a short period of time. Once it has been determined if the moss grew as a result of poor drainage, excessive shade, a lack of the proper nutrients in the soil, or the improper pH level, measures must be taken to correct these situations.
