    Can A Moss Killer Be Applied Before The Moss Is Removed

    Clay Tile Roof Cleaning

    This is a common question, can/should a moss killing chemical be applied to the roof before the moss is removed?

    The answer is no.

    First, you would need much more of the chemical as the moss would soak it up.

    Second, thick layers of moss will prevent the chemical from soaking into the tile/overlaps.

    Third, if you were thinking of applying the chemical instead of manually removing the moss with a scraper, then you would have a big problem the dead moss would gradually wash down into the gutters and block them. It could take months if not years for all the moss to wash off the roof. Your gutters would need frequent cleaning and even then they are still likely to become blocked.

    Keep An Eye On Your Roof

    You should regularly inspect your roof tiles for problems such as cracks, broken tiles, or gaps where old tiles have fallen away. This is vital as these nooks and crannies are the ideal breeding ground for moss and algae, which if left unchecked could cause you serious and expensive problems in the long-term.

    Coat Or Impregnate The Roof Tiles

    Clay Tile Roof Cleaning | Pressure Washed Then Soft Washed

    Roof tiles that have been polluted with moss generally have a porous structure as well. This does not apply to glazed roof tiles. Ceramic roof tiles that are not glazed however, become porous by age. Cleaning under high pressure may also contribute to higher rates of wear and tear of the top layer. As a result of this, it is often required to protect the tiles against pollution and new moss formation after the cleaning is done. This can happen in two ways: by means of coating or by impregnating.

    Coating the roof

    When coating, a coloured or transparent coating is sprayed onto the roof in two layers. This will be done under high pressure in order for the product to fill all corners and gaps. The coating method is especially chosen when the tiles dont look good anymore, not even after cleansing. If the roof tiles are still good-looking, one mostly opts for impregnating.

    Many people use pressure washers to clean their roof tiles, however this can do more harm than good, as the immense pressure from the water could damage your tiles or their coating. This is why we recommend using equipment such as a garden sprayer, or even a low-powered hose along with a gentle brush to carefully and safely clean each roof tile.

    Be sure to be particularly aware of your surroundings and consider your footing when washing your tiles. This is the most dangerous part of cleaning your roof tiles, as this is when the roof is at its most slippery.

    Cleaning And Removing Roof Algae And Moss

    Roof or wall tiles are often covered with moss or algae if its 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. Dont use the crap thats 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 dont 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 products recommendation to dry roof.

    A small amount of moss is not a problem and this appears on nearly all tiled roofs of a respectable age. However, as a mossed roof is getting older, mosses may gain the upper hand at a certain moment in time.

Along with this, types of weeds could start to grow and root in the moss or even in between of the roof tiles. All of this is not beneficial to the condition of the roof.
