Moss growing on your roof might look like something out of a dream, adding an air of quaint to a cute cottage. However, when you come back to the real world, you need to know that moss on your roof can cause some serious harm. If you fail to clear moss clumps from your roof, it can shift shingles out of place and degrade the quality of materials. The best thing you can do is regularly maintain your roof, which will include the removal of moss. If you catch moss early, you can avoid having to pay for expensive repairs. Throughout this article, we will tell you everything you need to know about removing moss from the roof.

Moss Treatments

Before we jump into the how, we’ll give you a quick note on available treatments. Each store-bought moss treatment will work differently, so you will need to check the label. For the most part, you will need to apply the treatment, leave it, and then rinse it off. When you’re cleaning the roof, you need to make sure you’re using the correct amount of chemicals. If you get it wrong, you can cause reactions to the roof and end up having more than just a cleaning task at hand.

If you want to save yourself some money, you can make moss treatments yourself. To do this, you need to add ¼ bleach for each gallon of water you use. Once you’ve done this, pop in some heavy-duty cleaner. For DIY treatments, you should avoid using ammonia-based products because they will let off toxic fumes when it hits the bleach. 

Things You Will Need

Going up onto the roof is dangerous, so you need to make sure you’ve got the correct gear with you:

  • Rubber gloves
  • Soft-bristled brush – preferably long
  • Stable ladder
  • Protective eyewear
  • Your treatment of choice – store-bought or homemade
  • Backpack sprayer – leaving your hands free
  • Garden hose
  • Old clothes and a protective hat
  • Scrubbing brush

Instructions

  1. Before you do anything, you need to make sure you’re wearing protective gear. No matter how careful you are, you will come down from the roof filthy.
  2. If you’ve got any exposed flowers nearby, you need to cover them up to protect them from harsh chemicals.
  3. Position the ladder in a sturdy place and secure it to the building if you’re working along. To ensure you stay on the ladder, you should be wearing non-slip safety boots.
  4. You need to make your way to the top of the roof and use the hose to spray the moss. Water will run down the roof, so there’s no point in starting from the bottom.
  5. Once you’ve got the moss wet, you should remove any large clumps with your long bristle brush. To make the job easier, you should work on square meter patches at a time.
  6. Once an area is clean from moss, you can apply your chosen treatment and follow the solution guidelines. If you’ve used a homemade treatment, you should leave it for 20-minutes and then rinse it off.
  7. Once you’ve rinsed off the treatment, you need to take your brush and put some elbow grease into any remaining moss.
  8. When all of the tiles are clean, you need to rinse the entire roof to double-check. Then, it’s time to pack everything away.

Keep Moss Away

Unfortunately, moss has a habit of coming back. You need to take measures to keep it at bay. The primary reason for moss growth is a lack of sunshine. So, if you’ve got overhanging trees blocking the sun’s path to your roof then it’s time to get rid of them. Further, moss thrives in moist conditions and collects it up like a sponge. You should clean your gutter out and ensure water can flow off your roof freely.

Luckily, there’s a more permanent method of keeping moss away. You need to fetch a strip of copper or zinc and apply it all the way across the ridge of the roof. The copper and zinc hold moss-killing properties that are released during periods of rain. If you carry out this last step, you won’t need to go through the effort of cleaning moss again. All you need to do is maintain the copper wire and carry out other roof maintenance.

Moss may look like a scene from a dream, but the reality is much more a nightmare. If you leave moss to grow and get out of control, you are asking for further damage. Moss will get in between your shingles and force them apart when it has soaked up enough water. You will need to choose an effective cleaner that’s safe for the environment – the last thing you want to do is kill your maintained garden. Remember, to keep the moss away for good, you need to run a copper or zinc wire across the ridge of your roof.
