Why Clean Your Roof?

Prevent Damage from Moss, Algae & Lichen

Moss and lichen thrive in damp UK climates. Left untreated, they can:

Lift or displace tiles, particularly concrete or clay ones
Trap moisture, leading to erosion or cracks (especially during winter)
Cause unsightly stains, especially on terracotta and concrete tiles

Reduce Wear & Tear

Over time, dirt and pollution wear down your tiles' protective coating. Regular cleaning helps preserve this layer, keeping tiles resilient to UV, moisture, and wind exposure.

Prevent Water Penetration

Organic build-up can cause small gaps or cracks that let water in. When that water freezes, it expands — potentially cracking tiles. Removing moss and debris stops this damage before it starts.

Protect What’s Underneath

Water-trapping growths can damage the underlayment or wooden battens under your tiles. A clean surface protects not just the roof tiles, but the structure beneath.
