Roof Moss Killer Buyer’s Guide

Moss is an unwelcome visitor and, if left untreated, can damage the structure of your roof. Luckily there’s a range of moss killers on the market that are easy to apply to problem areas. These are generally safe and easy to use, killing the moss and preventing it from returning.

Not sure what to look for when it comes to the best moss killer? Check out this buyer’s guide.

Efficiency

The most efficient moss killers will produce results quickly and with minimal effort needed on your part. Look for a moss killer that can be applied easily and that prevents moss from regrowing. While they won’t last forever, many can prevent moss from returning for up to a year – meaning an annual application is all you need.

Coverage

The coverage is measured in square metres and refers to the size of roof the moss killer can treat. If you don’t have a huge amount of moss, you may be able to dilute the solution more, giving you a wider coverage area and greater value for money. Most moss killers will have a long shelf life, so you can use the same batch for the next application.

Ease of Use

It’s important that your moss killer is easy to use, especially if you’re going to be applying it to your roof. Most can either be brushed or sprayed directly onto the unwanted moss. The moss will die within a few days.

Safety

Anything that kills plants should be handled with care, and moss killers are no difference. However, most are very safe to use so can be used on areas that receive a lot of footfall such as terraces or patios. The best moss killer for roof tiles will be biodegradable, leaving no lasting impact on your roof.

Moss Killer for Roofs FAQ

When to apply moss killer to the roof?

The best time to kill moss is when it’s actively growing. This happens when the weather is warm but not too hot; either late spring/early summer or late summer/early autumn.

If you want to remove the moss in the winter, you may need to carry out two treatments instead of just one. Apply the moss killer between October and December, then another between January and March.

Conclusion

Fighting against unwanted moss can feel like a never ending battle! Home moss killers have proven very effective and extremely easy to use. For its safe formula, wide coverage area and ease of application, the Wet & Forget Moss Remover is our top recommendation.
