Last autumn, we got a call from a couple in Gourock who were considering replacing their roof entirely. Their tiled roof was stained green with moss and black with years of pollution and grime. Water was starting to seep through in parts, and they were convinced the only answer was a full re-roof.

We recommended a steam clean before making any drastic decisions.

Three days later, after a meticulous steam roof cleaning process, the original tile emerged from beneath the muck looking almost new. The leaks? Caused by blocked drainage channels choked with moss—not broken tiles. We saved them over £10,000 in unnecessary roof replacement costs.

That’s the power of a proper clean. That’s the Pristi-clean difference.
