Moss and lichen on clay-tiled roofs
Much Hadham's older clay tiles are porous and shaded by mature trees, so moss and lichen establish quickly on north-facing slopes. We hand-scrape the growth, clean with low-pressure washing and steam, then apply a biocidal treatment. Our roof cleans keep moss and algae away for at least 6 years; after that, a quick biocide top-up keeps your roof protected.
