The main reason for keeping a roof covered is to prevent mould and moisture from building up in the cracks between the layers of tiles and concrete, says the National Roof and Landscape Association.
If you’re cleaning your roof regularly, you may find the tiles and the concrete are no longer the only thing keeping the roof from rotting.
However, when you have the time, it’s worth washing and cleaning the roof regularly to ensure the tiles are in good condition and are free of mould and other problems.
And it’s also good for the environment.
You want to get rid of all the dirt, dust and grime on the roof to prevent it from getting into the drains and basements and damaging the pipes and grates.
If there is any dirt or dust in the tiles, it needs to be removed, according to the RRLA.
To avoid damaging your tile surfaces, use a dust and mildew remover or airbrush to wipe them with a paper towel, says RRLF.
If your tiles and roof have become a source of mould or other problems, you can use the RFLA’s Cleaning of Roofs guide.
The guide provides an overview of the various cleaning methods and advice on the best way to do it.
