Gerard Roof Refresh – roof maintenance solution
Gerard Roof Refresh is a powerful cleaning agent formulated to target organic growth like lichen and moss – a natural phenomenon that occurs on most permanent outdoor structures including your roof.
Why would my roof need cleaning?
Left unchecked, organic growth can cause damage to the surface coating of your roof and can create ‘moisture traps’ that cause corrosion.
Recognising different types of growth
There are several ‘nasties’ to look out for including mosses, algal growth (which may be seen as either a green or black staining of the surface) and lichens; these can vary from light green through to bright orange, in a number of different shapes.
Prevent growth before it happens
Treating the roof will not only kill any growth, but also the spores that lead to it. Spores may be present on the roof for up to two years before the appearance of any organic growth.
We suggest treating the roof every three to five years, however if you see growth occurring sooner, we recommend you act immediately.
