Roof problems
Moss removal from roof surfaces prevents secondary damage
Moss, lichen and algae on a roof disturbs the flow of rainwater across the roof surface. Growth thrives where the supply of moisture is best and establishes itself where the slates overlap especially along the lower edge, the tail end, of the slate.
During heavy rain, the lap cavities will overflow inside the building. Most roofs have a notional second line of defence in the form of a bituminous felt, but it does not always perform perfectly and is not designed for long term protection.
The battens and fixings, situated above the felt undergo accelerated decay.
Moss release small amounts of organic acids that are corrosive to metal, particularly the lead and zinc used in soakers and flashings.
Applying MossGo Pro to a roof will kill the moss and remove moss and lichen growth before more damage occurs.
Cleaning moss and lichen from slate roofs
On roof slates, lichen dots, sometimes as large as plates colonise the roof. Moss balls sometimes form at the tail, the lower edge of the slate, particularly on man-made roofing slates.
Wet areas on roofing slates
Dirt creeping into the laps is a result of the capillary action of rainwater, something that is inceased by the presence of moss and lichen, resulting in the nail holes being in wet areas.
