Nail Sickness occurs when the nails that secure roof tiles or slates on a sloping roof deteriorate and, subsequently, tiles or slates become loose and may even slip off. The malady is particularly common in older buildings where fixer-nails were produced with only mild steel that is more susceptible to rusting and breaking.
How to deal with Nail Sickness
If Nail Sickness is identified in its early stages then small maintenance repairs can be made to affected areas. If the problem is ignored then matters become much worse. A roof suffering from a serious case of Nail Sickness must be stripped and resurfaced. A Surveyor ought to be contacted in these cases in order to provide expert advice. .
