Roof sealant is applied once the roof has been cleaned to provide an additional layer of protection to the tile surface. As roof tiles age and weather, they can become more absorbent, allowing moisture to soak in more easily and contributing to staining, surface wear and organic growth.
A quality roof sealant helps reduce water absorption by creating a more protective surface over the tiles. This can help the roof stay cleaner for longer, improve its overall appearance and give added protection against the effects of rain, frost and general weathering.
