How Long Will My Moss Treatment Last?
Our product has a 1-year guarantee. If you have green on your roof within a year, it means that we missed something and will retreat your roof at no extra cost to you.
In the damp, shaded spots, moss can be visible on a new roof in 2 years. However, in most cases, this product lasts 3-5 years before re-treatment would need to be considered.
Re-treatment is not as expensive as moss removal, so when you see that moss starting to come back, get in touch ASAP to keep your costs down and your roof in tip top condition.
