Will Having Moss Removed Actually Damage My Roof Tiles?

The Direct Answer

Roof damage during a moss removal job almost always comes from one of two things: pressure washing, which strips the protective surface off tiles and can force water under flashings, or someone physically walking on a roof that was never built to take foot traffic, which cracks tiles that were not cracked before. Steam cleaning from 45-foot poles on the ground avoids both, since nothing touches the tiles except the steam itself and nobody climbs up at all.

Where the real risk comes from

• Pressure washing. High pressure aimed at a roof strips the surface and can force water past the laps between tiles and under the flashings, exactly where you do not want it going.
• Walking the roof. Concrete and clay tiles are not designed to be stood on. Someone walking a roof to scrape moss by hand is how tiles end up cracked that were not cracked before the job started.

Why pole-and-steam avoids both

Steam delivered through an extension pole reaches the full roof from the ground, lifting moss without the stripping pressure causes, and without anyone needing to climb up. The gutters catch everything that comes off, and they get cleared as part of the same job.

What about the biocide treatment afterward?

Applied the same way, from the ground, and it is what actually stops the moss coming straight back — holding it off for three years minimum, less on shaded or north-facing roofs that stay damp longer.

FAQ: Will I need scaffold?

No. That is the whole point of working off poles from the ground — no scaffold cost and nobody walking on your tiles.
