Roof Surfaces
Pre-Painted Roofs
If your roof has been previously restored and has moss growing on it, most people think that pressure cleaning is the solution to keeping the roof clean. Unfortunately depending on the quality of the paint coats and primer pressure cleaning can remove the colour coats leaving the roof looking faded and untidy.
Moss Roof Treatment is perfect for Pre-Painted roofs as it does not affect the paint coats. MRT will kill the moss, mould & lichen on the tiles, it will then wash off overtime, revealing the colour coats, keeping the roof clean.
