Moss usually finds a home in an environment that is damp and has lots of moisture content surrounding it. This is what usually causes its growth during rainy winters on your roof. While most removal methods end up harming streams, lakes, wetlands and the environment in general, there are certainly effective and eco-friendly ways in which it can be done.
First of all, understand the amount of moss that you have on your roof and whether it possesses a serious threat. After understanding the amount of moss you have growing on your roof, try and look for preventive measures. Check our other article about roof cleaning.
Well lit areas are not prone to the growth of moss. Thus, you can try either of these methods –
- Prune branches which provide shade on your roof as they also lead to falling leaves and needles – Moss manages to accumulate well in shaded areas. When you prune, you make sure that instead of unnecessary shading, sunlight manages to enter, which not only slows down but also prevents the growth of moss. You don’t have to cut down the entire tree, just a few branches here and there, especially those which provide an unnecessary shade on your roof, will be more than enough.
- Try to keep the surface of your roof clean – Attempt to clean your roof at least once or twice a year so that any debris or dirt which may have found shelter on your roof is removed.
- Keep a watch for any early signs of moss growth – This can usually be understood through green and black discoloration. The moment you notice a spot having such colors, know that moss is growing and immediately treat it and prevent it from spreading.
Other than preventing the growth of moss, there are also ways in which you can kill it off or remove it physically. Since summers ensure abundant sunlight, it is an ideal time to get rid of moss on your roof. If you notice the roof is safe enough for movement, with the help of hand tools and not power washing try and remove the moss because it tends to damage the shingles and often leads to the gathering of water under it. You can make use of a leaf blower too or try gentle sweeping. Both are equally effective.
Remember that in case you are not confident, hire someone to do the work for you. Avoid doing it, if you begin to get cold feet because then you might just end up injuring yourself.
Avoid using any form of chemicals such as zinc sulfates and copper sulfates because not only are they non-biodegradable but they also cause excessive corrosion to the skin and eyes. Also, if you end up using chemicals, most of them get washed out when it rains and ends up harming not only the environment but also different forms of aquatic life and poisons surrounding water bodies such as lakes, rivers, and streams.
So be wise and be eco-friendly!
