For many concrete and terracotta tiled roofs, yes. Roof paints and coatings sit on the surface and can peel, crack and require ongoing maintenance over time. A penetrating sealer works from within the tile, providing long-lasting protection without creating a surface coating that can break down. It also maintains the natural look of the roof and typically costs significantly less than a full restoration or repaint.

We avoid high-pressure cleaning on tiled roofs. Instead, we use specialised treatment solutions to break down moss, lichen and organic growth at the source, followed by controlled low-pressure rinsing to clean the surface safely without causing damage to tiles, pointing or surrounding areas.

In most cases, a quality penetrating sealer will provide protection for up to 5 years, depending on the condition of the tiles, local weather exposure and the level of organic growth in the area. We assess each roof individually and provide honest recommendations on whether sealing is the right option for your specific situation.
