Tools That you’ll Need

You will need some simple tools in order to clean roof tiles. Below is the list of required equipment:

Safety First

Although cleaning roof tiles is not that dangerous. A simple mistake can lead to a damaged roof or you might even hurt yourself. So you need to take care of everything to avoid any incidents.

So, before you start washing the tiles, ensure safety has been actively considered. Use personal protective equipment and other safety equipment.  Get these things first,

  • Fit a temporary safety rail
  • Wear firm, non-slip boots
  • Wear chemical protective gloves
  • Wear wraparound safety glasses
  • Safety line and harness

These safety tools are essential for any size and pitch of home/commercial space roof. The safety line and  safety harness may not be required for all kinds of roofs and they are only needed for high pitched roofs where there’s a lot of algae growth and roof moss.

Algae/moss can make the surface extremely slippery. It’s best to work with a partner so that he can pass the tools and materials up onto the roof. Otherwise, you’d have to keep going up and down to get one tool and return the other, which would delay work and spoil your rocking mood and may even lead to accidents?

Disconnect Water Tanks and Clear Your Guttering

If the gutter system of your home is connected to the water storage tank, disconnect it before you start to clean since the tile cleaning procedure uses a lot of chemicals. If the water storage is combined with the guttering system, the compounds may somehow find their way into the storage.

If the gutter has not been cleaned for a while, you should clean it before you start to clean the roof. You can easily do it yourself using just a gutter brush. Furthermore, use a gutter guard if the gutter easily fills with debris.

Cleaning and Removing Roof Algae and Moss

Roof or wall tiles are often covered with moss or algae if it’s not cleaned for more than 3 months. Random moss spots here and there are easy to clear, but the excessive build-up of algae and moss is pretty hard to remove. Use a roof scraper to scrape the extra debris from the tiles. Also be careful to not damage the tiles. You can easily find many kinds of roof scrapers designed for scraping. Don’t use the crap that’s used for lawn scraping. Those could potentially damage the tiles.

Now that the thick moss and page pad is obliterated, apply an anti-moss spray. If your manufacturer has a particular recommendation for this job, feel free to buy that spray. If you don’t like chemical solutions you could also make a DIY spray if you want. Your tile roofs could be sensitive to particular chemicals. If there is any mention of a particular chemical, obviously avoid buying any spray that contains them.

Spray the bottle by walking away or backward from where it has been applied. Which means you should not step into the wet, treated surface. Once you are done spraying the moss killers let it rest for some time or as per the product’s recommendation to dry roof.

Use Water to Clean Your Roof Tiles

Now it’s time to wash away the anti-moss spray and other debris off the entire roof with clean water. Some people use high-pressure water spray to clean the tiles, but that can damage the tiles. It’s better to use a low pressure water hose and gentle brushes to clean the tiles thoroughly.

At this point, the tiles become wet and slippery. You better use all the personal and other safety equipment and get help from your partner.

Also remember…

If this technique doesn’t work on your roof tiles, then hold on a bit before you apply any harsh chemical without considering the consequences, you better consult with an expert to ask for help.

As you know, roof tiles are not something we use for a short amount of time. You will be using them for many more years to come and so it is important to consider the health of tile’s structural condition as it is both essential and beneficial for the future.

Its’ possible that there might be other changes needed to make the tiles entirely clean and shiny. Some people start to clean with a DIY cleaner made from a combination of vinegar and liquid soap and let the tiles soak for a while. That makes the cleaning quick and results in a much shinier surface.
