How to Remove Moss from a Roof
It can be difficult to remove moss from a roof but by following a few simple tips you can make the job a lot easier.
It can be difficult to remove moss from a roof but by following a few simple tips you can make the job a lot easier.
Moss grows on roofs in many parts of the world, especially those areas that experience heavy rain regularly. Moss is often found along with lichens and algae on roofs, decks, walkways and other outdoor structures. As moss is a living plant that feeds on roofing material, it will make holes in your roof over time. That is why you need to remove moss from a roof before it can cause any damage.
So how do you remove moss from a roof?
The first thing to remember is that it is not just a question of how to remove moss from a roof but also how to stop it coming back as well. Organic debris is the main cause of moss growth on a roof. When it rots, it turns into a rich, compost like soil in which moss spores grow and are then blown into the air before landing on your roof. So to stop moss growing you need to make sure that you keep your roof clean.
The first thing you need to do in order to remove moss from a roof is to clean off any organic debris that has been deposited on it. The best tool to use to remove moss from a roof is a plastic rake that will dislodge and loosen even the largest clumps and make the job a lot easier. The next step in order to remove moss from a roof is sweeping it with a soft bristle broom to clear away the smaller clumps that have been loosened by the rake.
Once you've got rid of these clumps, you need to clean and scrub to remove any remaining moss clusters. You can do this with half a cup of powdered detergent added to ten gallons of warm water and detergent or with bleach. Once you have cleaned and scraped your roof, you need to apply a repellent and keep it clean to stop the moss growing back again.
