Occasionally you may need to fix or replace roof tiles, there are also other key factors of keeping your roof in great condition, watching out for moss and lichen is extremely important. This unsightly growth thrives in warm & moist conditions, roofs are the ideal place for this to grow.

Moss & Lichen can appear if you neglect cleaning gutters also debris on the roof that slow down the drainage of rain from your roof.

Once moss and lichen is present it can change the tile surface of the roof not just effect the appearance.

Moss can grow thick like patches of grass and has the ability to hold extra moisture, this can damage the tile service or wear away at the tile roof until surface water is entering the roof and cause damage to internal ceilings. Moss can also grow between the tiles and cause leaks inside of the roof space.

Our moss control for roofs can eliminate the re-growth by applying our moss control spray.
