Restore and Protect Your Roof the Safe Way

At TM Exterior Clean, we specialise in safe, effective roof cleaning that brings your tiles back to life without risking damage. Our three-stage process – roof scraping, low-pressure washing, and biocide treatment – is designed to thoroughly remove moss, algae, and grime while extending the lifespan of your roof. Whether your tiles are lightly weathered or heavily overgrown, we have the tools, training, and experience to clean them the right way.

Roof Scraping

The first stage of most cleans involves manual roof scraping. This is carried out using specially shaped tools that match your roof tile profile, allowing us to remove moss and lichen thoroughly without cracking or disturbing the tiles themselves. Scraping clears the worst of built-up growth and gets the roof ready for further treatment.

Low-Pressure Roof Cleaning

Once the bulk of the moss and growth is removed, we carry out a low-pressure roof wash. This is designed to clean away finer debris, surface grime and any leftover organic material. We focus on cleaning the surface in a way that’s thorough, gentle and safe for all roof types.

Biocide Application

To finish, we apply a professional-grade biocide treatment to prevent moss and algae from returning too quickly. This solution continues to work long after we’ve left, breaking down any remaining spores and helping to preserve your clean roof for months and even years ahead.
