Roof Surfaces

Laserlight Roofs

Little or no maintenance occurs on laserlight sheets, however over a period of time moss growth blocks out light and looks unsightly. Some owners would see that it needs to be replaced which can be quite costly. MRT is perfect for laserlight surfaces as it is a gentle application process and does not require harsh pressure cleaning.

Laserlight generally cleans up the quickest, we allow 6-12 months for this process, depending on viscosity and weather.
