Moss and Lichen are a Roof’s Top Enemy
Lichen is one of the most damaging issues that your roof can face. It’s slow growing but incredibly strong, sending filament roots into the surface of your roof, creating micro-cracks in the paint, eventually finding the bare steel underneath. Colorsteel is fantastic stuff but it can’t stand up to the force of well-established lichen.
Concrete, decramastic-style and tiled roofs have natural cracks and joins. Plants like Lichen and Moss creep into these cracks and open them up further.
