Cement Roof Cleaning

Cement tiled roofs can be kept clean and protected without the risks of pressure cleaning. Moss Roof Treatment kills moss, mould, and lichen at the source, preventing further growth. Over time, the dead growth naturally washes away with rainfall—helping you avoid the damage and costly repairs that pressure cleaning can cause.

This treatment is also ideal for maintaining your roof after other repairs, without the need for a full roof restoration.

• Surface Damage from Cleaning - High-pressure washing can strip away the tile colour, damage the surface, and disturb pointing.
• Weaker Tiles - Some cement tiles are thinner or more fragile, making them unsafe for walking.
• Moss on Pointing - Heavy moss growth can force cracks open in the pointing, allowing water to enter the roof and cause leaks.

By treating the roof instead of pressure cleaning, you maintain the strength of the tiles and avoid expensive repair work.

Our moss treatment is applied gently under controlled medium pressure. It penetrates the tile overlaps, humps, and rough front edges where moss and black mould often grow. This kills spores at the source, prevents regrowth, and keeps your roof cleaner for years to come.

• Before Solar Panels - Treating cement tiles before installation ensures the roof is safe to walk on and prevents moss from spreading to panel frames.
• After Repairs - Following pointing or valley repairs, moss treatment helps protect the work and prevents the need for repeat repairs.
• Better Water Runoff - A clean roof ensures water runs into the gutters, not into the roof cavity.
• During Renovations - Treating the roof before building an extension ensures it looks clean and fresh when the project is complete.
