If your roof is covered in moss we recommend our roof moss removal service. The damp climate in the UK can create the perfect conditions for moss, algae and lichens to thrive on a roof. Not only does moss look unsightly but it can also cause other problems such as gutters and downpipes becoming blocked. In addition, the extra weight of wet moss can cause stress on the roof structure. What's more, during winter the freeze-thaw process may cause tiles to break. This can cause premature degradation and the appearance of your roof to deteriorate. Plus it could also cost you a substantial amount of money in roof repairs.
