Concrete roof tiles are a popular choice for homeowners across the UK thanks to their strength, longevity, and weather resistance. However, like any roofing material, they still require periodic care to stay in top condition. At LS Roofing Didcot, we regularly advise property owners in Didcot, Oxfordshire on the best practices for maintaining their concrete tile roofs—ensuring they stay attractive and functional for decades.
Why Concrete Tiles Need Maintenance
Although concrete tiles are known for their durability, they are not immune to the effects of weathering, biological growth, or minor movement. Left unchecked, these issues can lead to leaks, broken tiles, or an unsightly roof. A regular maintenance schedule helps prevent costly repairs and keeps the property looking well cared for.
Key Cleaning and Maintenance Tips
1. Inspect Tiles Annually
Routine inspections, especially after heavy storms or high winds, help identify cracked or dislodged tiles early. Look out for broken corners, slipped tiles, or exposed underlayments. If climbing a ladder isn’t an option, consider booking a professional roofing survey for peace of mind.
2. Remove Moss and Algae Growth
Concrete tiles are prone to moss, algae, and lichen build-up, particularly in shaded or damp areas. While some homeowners attempt to scrape moss off, this can damage the tile surface. A gentle, specialist roof cleaning treatment is far safer and more effective, usually applied by professional roofers using low-pressure equipment.
3. Clear Debris From Valleys and Gutters
Twigs, leaves, and other debris often collect in roof valleys and gutters. This can block water flow and encourage moss growth. Regular clearing, especially in autumn, helps maintain proper drainage and reduces pressure on tiles during heavy rain.
4. Avoid High-Pressure Washing
Using a power washer can dislodge tiles, damage their protective coating, or drive water underneath the tile surface. If cleaning is required, a soft-wash approach using eco-safe biocides is the recommended method for preserving the integrity of concrete tiles.
5. Check for Mortar Decay
The mortar used around ridge tiles, verges, and hips can crack or crumble over time. Damaged mortar joints can lead to loose tiles or water ingress. Repointing or replacing mortar is a small job that can prevent much larger issues.
6. Keep Overhanging Trees Trimmed Back
Trees can drop organic material onto your roof, increasing the risk of moss and lichen. Overhanging branches also present a physical hazard during storms. Keeping trees trimmed back helps protect the roof from both direct and indirect damage.
7. Treat the Tiles to Extend Their Life
Some roofs benefit from a protective sealant applied after professional cleaning. This helps repel water, slow future moss growth, and enhance the tile’s colour. Speak to your roofing contractor to see if this option is right for your roof type and condition.
