Noticing your roof looking a little run-down, with moss spreading and dirt making it look dull? Brisbane’s weather can be tough on roof tiles, and regular cleaning is important to keep grime, algae, and moss from wearing down your roof and taking away from your home’s appearance. Without regular upkeep, these issues can cause early damage, lead to expensive roof repairs, and even result in roof leaks.
The good news? With the right approach, keeping your roof in good shape doesn’t have to be complicated. This guide covers all you need to clean roof tiles safely and keep them looking great year-round.
Our 7-Step Process for Cleaning Roof Tiles
1. Inspect & Identify Roof Tile Type
Before starting, it’s important to know what type of roof tiles you have. Terracotta, concrete, and clay tiles are common, and each has specific cleaning needs. The type of tile you have will help you decide what cleaning method to use and avoid damage. Look at your roof and see if there is moss, algae, or dirt buildup that may need special treatment.
2. Set Up Essential Safety Precautions
Roof cleaning can be risky if proper safety measures aren’t in place. Make sure to have a sturdy ladder, and consider using a safety harness for steeper roofs. Roofs can get slippery when wet, so non-slip shoes are essential. If you don’t feel comfortable with heights, calling for a professional roof cleaning Brisbane service is the safest option. When working on a roof, it’s always a good idea to take a few extra steps for safety.
3. Prepare the Roof & Surrounding Area
After safety steps are done, it’s time to get the roof area ready. Begin by clearing any loose leaves, branches, or debris from the roof, as these can clog gutters or get in the way during cleaning. Also, move or cover any furniture and plants around the base of the roof to protect them from splashes of cleaning products. Proper preparation keeps your property and garden safe from damage and makes the whole job go smoothly.
4. Choose the Right Cleaning Method for Your Tiles
Roof tiles are tough, but using the wrong cleaning method can cause cracks, chips, or staining. Terracotta, concrete, and clay tiles each require a specific approach to clean thoroughly without causing damage. Here’s how to clean each tile type safely and effectively.
Terracotta Tiles
Terracotta tiles have a beautiful, natural look but are more delicate than some other types. Avoid using high pressure on these tiles, as they can crack under strong force. For a safer clean, stick to low or medium pressure. For tough spots, use a soft brush with a mild cleaner to gently lift dirt and stains.
Concrete Tiles
Concrete tiles are durable and can handle more pressure but still benefit from a moderate approach to avoid chipping. Begin with gentle pressure and then progress through the area in order to get an even cleaning. If you spot moss or algae, a diluted bleach solution can help. Just rinse well afterwards to avoid residue that could discolour the tiles.
Clay Tiles
Clay tiles have a timeless, earthy look but need careful handling to avoid cracking. Use only low-pressure washing and avoid harsh chemicals. For tough stains, use a soft brush and mild soap.
5. Pressure Wash or Scrub Your Roof Tiles
For most homes in Brisbane, using a pressure washer can effectively remove dirt, moss, and algae. Just make sure to set it correctly—a pressure of around 1500 PSI is usually strong enough to remove grime without harming the tiles. Hold the nozzle around 30 centimetres from the surface. Start from the bottom and move up to prevent water from slipping under the tiles. If there are tough stains, you can use a stiff brush and a mild roof-safe cleaner. Always double-check that the cleaner is safe for your specific tile type.
6. Apply Anti-Moss or Anti-Mould Treatments
After cleaning, consider applying an anti-moss or anti-mould treatment to slow down regrowth. Choose a treatment designed for roof tiles, and apply it with a garden sprayer or through your pressure washer on a low setting. Just make sure the treatment is safe for your tile type, and remember to give the roof a good rinse afterwards. It’s an extra step that will help keep your roof cleaner for longer, especially in Brisbane’s humid climate.
7. Final Rinse & Post-Cleaning Check
After you’ve finished cleaning, give the roof a final rinse to wash away any leftover residue or cleaning products. Then, do a quick inspection for any potential issues. Look for loose or cracked tiles, broken edges, or clogged gutters. A quick post-clean check can help you catch small issues before they become bigger problems and save you time and effort down the road.
