How to clean clay roof tiles - roofing maintenance

Maintaining and cleaning clay roof tiles can be seen as a relatively simple task and typically just requires a bit of water and a cleaning solution. However, working at height can be dangerous, so it’s always better to leave the job to the professionals.

The importance of roof maintenance

When you look at your home, the roof is one of the most noticeable features, and clay roof tiles provide a beauty that you’ll want to retain. Taking care of those tiles will help to increase kerb appeal, as well as your own satisfaction with your home, while also ensuring the long-term performance of the roof.

The good news is that clay roof tiles mostly take care of themselves. They require very little maintenance, and cleaning is only really necessary if you notice a build-up of lichen or moss.

Cleaning clay roof tiles

While the need to clean roof tiles is rare, it may be necessary if you notice mould, lichen, moss, or algae growing on the tiles. If left alone, these issues can lead to cracked or damaged tiles, meaning that they need to be replaced as well as other problems with your roof.

According to the Roof Tile Association, scraping off algae, moss or lichen growth is not recommended, as it can result in broken or damaged tiles. Instead, a toxic wash is typically the best option. These must be applied carefully, as they can be dangerous to animals and humans, and they require proper disposal when the project is complete.

Because working from height is difficult and dangerous, since roof tiles can break if they’re stepped on, and because cleaning often requires the use of toxic substances, it’s best to contact a professional roof cleaning company if you notice any problems. They will be able to access the roof safely, and they should know how to work without damaging the tiles.

We do not recommend using a pressure washer to clean clay roof tiles, as the high-power spray can damage the tiles.

Roof maintenance for protecting clay roof tiles

While roof tiles require minimal cleaning and maintenance, it’s also important to look after the overall condition of your roof to prevent problems from building up.

Be sure to keep the roof surface free from debris like leaves or branches. These often collect in places like valleys or abutments and can affect drainage. They can also attract birds or vermin, or lead to the growth of mould, lichen, moss and algae.

Gutters should also be kept clear to ensure good drainage, and any overhanging tree branches should be cut back to prevent items from falling on the roof.
